KitGuru has already reviewed many AMD HD6800 series cards and we have been impressed with the competitive pricing and mid range performance. The GTX460 dominated the market for many weeks but AMD finally stepped up to the plate.

Today we are going to look at the new HIS HD6870 Turbo Edition Card, which while featuring the same reference AMD cooling system, is supplied with modest overclocks. None of the leading manufacturers have yet to release a custom cooled HD6870, so it looks as if we will have to wait a while longer.

Many overclocked cards are hand picked from the production line to ensure that RMA's don't prove to be an issue long term.

The new 6800 series has seen hardware architecture changes with a focus on strengthening tessellation and geometry throughput. Avid readers of KitGuru will have seen over recent months that nVidia Fermi hardware has been leading the way in titles such as UniGine Heaven Benchmark, a synthetic test which relies heavily on Tessellation performance.

The 6800 series has a reconfigured core design which offers up to 2.0 TeraFLOPS and 24 Gigapixels per second performance. The command processor is linked to the graphics engine as seen in the diagram above, with the new generation 7 Tessellator. The Dual rasterizers and 12-14 SIMD engines tied to a 256 bit GDDR5 memory interface help to improve performance beyond the levels of the last generation, while using 25% less silicon.

	AMD HD5850	AMD HD6870
Die Size	334 mm2	255mm2
Transistors	2.15 billion	1.7 billion
Memory Bandwidth	153.6GB/sec	134.4 GB/sec
Geometry Throughput	725 million polygons/sec	900 million polygons/sec
SIMD Engines	18	14
Stream Processors	1440	1120
Texture Units	72	56
Z/Stencil ROPs	128	128
Colour ROPs	32	32
Max Board Power	151W	151W
Idle Power	27W	19W

The table above shows a direct comparison against the HD5850 and HD6870. The HD6870 has less texture units, SIMD engines, Stream Processors with a lower memory bandwidth but the Geometry throughput has been significantly increases from 725 million polygons per second to 900 million polygons per second. The new design is more efficient and with the die shrink requires less power at idle.

	Hardware Tessellator Progression
Generation 1	ATI Radeon 8500	Fixed Function PN Triangles (TRUFORM)
Generation 2	Microsoft Xbox 360	Displacement mapping, adaptive tessellation
Generation 3	AMD Radeon HD2000 family	Dirext X 10 compatibility
Generation 4	AMD Radeon HD 3000 family	Direct X 10.1 compatibility
Generation 5	AMD Radeon HD 4000 family	Performance Enhancements
Generation 6	AMD Radeon HD 5000 family	Direct X 11 compatibility
Generation 7	AMD Radeon HD 6800 Series	Improved Thread Management and buffering

The updated Tessellation unit, called ‘Generation 7' brings new thread management capabilities as well as buffering enhancements to the table. This means that performance is increased by up to two times when directly compared to the HD5000 series. This should mean that AMD are closely competitive with similarly priced nVidia Fermi hardware, we will look at performance later in this article. AMD's internal testing shows that the HD6870 achieves twice the tessellation performance of the HD5870.

Tessellation is a hotly discussed topic right now, and it is a bone of contention between nVidia and AMD. Our recent interview with Richard Huddy opened a few eyes, as he said “nVidia is pushing a single message and that’s tessellation. Tessellation is about enriching detail, and that’s a good thing, but nVidia is pushing to get as much tessellation as possible into everything. With artificial tests like Stone Giant, which was paid for by nVidia, tessellation can be done down to the single pixel level. Even though that pixel can’t be broken away from the 3 other pixels in its quad. Doing additional processing for each pixel in a group of 4 and then throwing 75% of that work away is just sad.”

AMD's stance on this is “Tessellating the Right Way” – which means a focus on the most efficient tessellation usage models with 16 pixels per polygon combining solid image quality with high levels of performance. Adaptive Tessellation is how they want to approach it, using high levels for objects close to the front of the screen (and in eye shot of the gamers) and then switch to lower levels for distant and simple objects to help improve performance while avoiding geometry aliasing problems.

The image above was captured from Alien V Predator and showcases the new Morphological Anti-Aliasing technique from AMD which is a post process filtering technique accelerated with DirectCompute. It delivers full scene anti Aliasing and it is not limited to polygon edges or alpha tested surfaces. The system is faster than super sampling with similar performance levels to edge detect CFAA, but it applies to all edges. This can be enabled from Catalyst Control Center and is compatible with any Direct X 9/10/11 supported application.

Anistrophic Filtering has also been fine tuned and enhanced with a newly refined algorithm in place. It addresses visible discontinuities in very noisy textures offering smoother transitions between filter levels. It also maintains full performance and angle independence.

The HIS HD6870 Turbo Edition card is supplied in an identical box to the reference edition, with the addition of a ‘Turbo' sticker top right.

The HIS sample includes a video converter, power adapters, Crossfire cable and literature with disc.

The HIS HD6870 is based around the AMD reference design so features the ‘traditional' cooling fan configuration on the right of the PCB.

The HIS HD6870 supports 2x mini DP (1.2), HDMI 1.4a, and 2x DL-DVI and SL-DVI connectors. It requires two 6 pin power connectors to operate. This card will expel hot air out the back of the chassis.

The reference HD6870 cooler is quite substantial, with a copper block running out to several small heatpipes. The fan is positioned on the far side so it forces air across the heatsink and out the rear of the case.

Two HIS HD6870′s in our system, running in CrossfireX.

Above, GPUz specifications. 920mhz (from reference 900mhz) on the core, and 1120mhz/4480mhz effective (from reference 1050mhz/4200mhz effective).

For the review today we have built a strong system which we feel would fit in well with the audience purchasing these cards. We are using a Core i7 950 Quad Core CPU with 6GB of DDR3 memory. We have applied a moderate overclock to the processor because we know you guys never run anything at reference speeds!

We are also going to limit testing to 1920×1080 (1080) and 1920×1200 as less than 1% of the enthusiast user base reading this will have a 30 inch screen – this will address the widest possible audience.

Test System: Validation here.

All the latest BIOS updates and drivers are used during testing. We perform under real world conditions, meaning KitGuru tests all games across five closely matched runs and average out the results to get an accurate median figure.

Unigine provides an interesting way to test hardware. It can be easily adapted to various projects due to its elaborated software design and flexible toolset. A lot of their customers claim that they have never seen such extremely-effective code, which is so easy to understand.

Heaven Benchmark is a DirectX 11 GPU benchmark based on advanced Unigine engine from Unigine Corp. It reveals the enchanting magic of floating islands with a tiny village hidden in the cloudy skies. Interactive mode provides emerging experience of exploring the intricate world of steampunk.

Efficient and well-architected framework makes Unigine highly scalable:

• Multiple API (DirectX 9 / DirectX 10 / DirectX 11 / OpenGL) render
• Cross-platform: MS Windows (XP, Vista, Windows 7) / Linux
• Full support of 32bit and 64bit systems
• Multicore CPU support
• Little / big endian support (ready for game consoles)
• Powerful C++ API
• Comprehensive performance profiling system
• Flexible XML-based data structures

1080p is a standard resolution we use with the Heaven Benchmark on all graphics cards, this means all review results are comparible throughout previous months.

Shaders are set to high, Tessellation to normal, anistrophy to 4 and Anti Aliasing is disabled.

The overclocks on the HIS card help it to generate an extra frame per second in Unigine, falling just behind the overclocked MSI GTX460 Talon card

Futuremark released 3DMark Vantage, on April 28, 2008. It is a benchmark based upon DirectX 10, and therefore will only run under Windows Vista (Service Pack 1 is stated as a requirement) and Windows 7.  This is the first edition where the feature-restricted, free of charge version could not be used any number of times. 1280×1024 resolution was used with performance settings.

The HIS HD6870 Turbo is close to the top of the pack, falling behind the GTX460 FTW edition and the HD5870.

Aliens V Predator has proved to be a big seller since the release and Sega have taken the franchise into new territory after taking it from Sierra. AVP is a Direct X 11 supported title and delivers not only advanced shadow rendering but high quality tessellation for the cards on test today.

To test the cards we used a 1080p resolution with DX11, Texture Quality Very High, MSAA Samples 1, 16 af, ambient occulsion on, shadow complexity high, motion blur on. We use this with most of our graphics card testing so cards are comparible throughout reviews.

The HIS HD6870 Turbo card delivers an average frame rate, just shy of 50, leading the pack and only behind the AMD HD5870.

Far Cry 2 (commonly abbreviated as “FC2 or “fc2″) is an open-ended first-person shooter developed by Ubisoft Montreal and published by Ubisoft. It was released on October 21, 2008 in North America and on October 23, 2008 in Europe and Australia. It was made available on Steam on October 22, 2008. Crytek, the developers of the original game, were not involved in the development of Far Cry 2.

Ubisoft has marketed Far Cry 2 as the true sequel to Far Cry, though the sequel has very few noticeable similarities to the original game. Instead, it features completely new characters and setting, as well as a new style of gameplay that allows the player greater freedom to explore different African landscapes such as deserts, jungles, and savannas. The game takes place in a modern-day East African nation in a state of anarchy and civil war. The player takes control of a mercenary on a lengthy journey to locate and assassinate “The Jackal,” a notorious arms dealer.

Far Cry 2 is still a popular game and the open world environment can be taxing on even the latest hardware available today.

Our settings: 1920×1200 (60Hz), D3D10, Fixed Time Step(No), Disable Artificial Intelligence(No), Full Screen, Anti-Aliasing(4x), VSync(No), Overall Quality(Optimal), Vegetation(High), Shading(High), Terrain(High), Geometry(High), Post FX(High), Texture(High), Shadow(High), Ambient(High), Hdr(Yes), Bloom(Yes), Fire(Very High), Physics(Very High), RealTrees(Very High).

nVidia cards have always been strong with the Far Cry 2 engine, and the HIS HD6870 Turbo edition manages to lead the AMD pack with an average frame rate of around 75. The overclocked GTX460 are significantly out in front.

Lost Planet 2 is a third-person shooter video game developed and published by Capcom. The game is the sequel to Lost Planet: Extreme Condition which is also made by Capcom, taking place ten years after the events of the first game, on the same fictional planet. The story takes place back on E.D.N. III 10 years after the events of the first game. The snow has melted to reveal jungles and more tropical areas that have taken the place of more frozen regions. The plot begins with Mercenaries fighting against Jungle Pirates.

After destroying a mine, the Mercenaries continue on to evacuate the area, in which a Category-G Akrid appears and attacks them. After being rescued, they find out their evacuation point (Where the Category-G appeared) was a set-up and no pick up team awaited them. Lost Planet 2 runs on the MT-Framework 2.0, an updated version of the engine used in several Capcom-developed games.

We are testing in DX11 mode.

Lost Planet 2 is a great looking game and the HIS HD6870 Turbo Edition manages to fall between the overclocked GTX460 eVGA board and the MSI GTX460 Talon Edition. There are some drops below the 25 fps mark, so a few compromises with IQ would have to be made to improve this frame rate.

Mafia II is a gritty drama which chronicles the rise of World War II veteran Vito Scaletta, the son of Sicilian immigrants. As the game progresses, Vito will join the Falcone Crime Family and become a made man. There are 15 chapters in the game, connected into one storyline.

We tested at 1080p with fullscreen: on, antialiasing:on , Anisotrophic filtering: 16x, Shadow Quality: High, Ambient Occlusion: on, Geometry Detail: High and APEX PhysX: off.

Even though Mafia 2 is an nvidia sponsored title, the HIS HD6870 Turbo Edition manages to push past the overclocked GTX460 cards, coming out on top with an average of 51 fps.

The makers of Metro 2033 – 4A Games was founded by people who split off from GSC Game World a year before the release of S.T.A.L.K.E.R.: Shadow of Chernobyl, in particular Oles’ Shiskovtsov and Aleksandr Maksimchuk, the programmers who worked on the development of X-Ray engine used in the S.T.A.L.K.E.R. series. The game utilizes multi-platform 4A Engine, running on Xbox 360, PlayStation 3, and Microsoft Windows. There is some contention regarding whether the engine is based on the pre-release X-Ray engine (as claimed by Sergiy Grygorovych, the founder of GSC Game World, as well as users who have seen the 4A Engine SDK screenshots, citing visual similarities, shared resources, and technical evaluation of the pre-release 4A Engine demo conducted at the request of GSC Game World), or whether the engine is an original development (as claimed by 4A Games and Oles’ Shiskovtsov in particular, who claims it would have been impractical to retrofit the X-ray engine with console support). 4A Engine features Nvidia PhysX support, enhanced AI, and a console SDK for Xbox 360. The PC version includes exclusive features such as DirectX 11 support and has been described as “a love letter to PC gamers” because of the developers’ choice to “make the PC version [especially] phenomenal”.

We tested at 1920×1080 with settings on default ‘normal’

The overclock helps the HIS HD6870 Turbo climb to a level footing with the HD5870 graphics card at the top of the pile. An excellent result.

Resident Evil 5, known in Japan as Biohazard 5, is a survival horror third-person shooter video game developed and published by Capcom. The game is the seventh installment in the Resident Evil survival horror series, and was released on March 5, 2009 in Japan and on March 13, 2009 in North America and Europe for the PlayStation 3 and Xbox 360. A Windows version of the game was released on September 15, 2009 in North America, September 17 in Japan and September 18 in Europe. Resident Evil 5 revolves around Chris Redfield and Sheva Alomar as they investigate a terrorist threat in Kijuju, a fictional town in Africa.

Within its first three weeks of release, the game sold over 2 million units worldwide and became the best-selling game of the franchise in the United Kingdom. As of December, 2009, Resident Evil 5 has sold 5.3 million copies worldwide since launch, becoming the best selling Resident Evil game ever made.

It is tight at the top of this test with the HD5870 just beating the reference clocked HD6870. The HIS HD6870 Turbo Edition however manages to climb past the reference clocked HD5870, scoring over 100fps.

Tom Clancy HAWX is set in the same universe as Tom Clancy’s Ghost Recon Advanced Warfighter; as Captain Scott Mitchell, the Ghost leader, is featured in a few missions of the missions. Plot elements are carried over from other Tom Clancy games such as the missile defense system found in Tom Clancy’s EndWar. G4′s interview with H.A.W.X’s lead designer Thomas Simon reveals that the game takes place in between Tom Clancy’s Ghost Recon Advanced Warfighter 2 and Tom Clancy’s EndWar.

The player begins the game in 2014 as the player assumes the role of former U.S. Air Force pilot, David Crenshaw, who is part of an elite unit called H.A.W.X (“High Altitude Warfare eXperimental squadron”), provides fire-support missions for the Ghost team carrying out covert operations in Ciudad Juárez, Mexico. However, shortly after the mission, the Air Force decides to deactivate the H.A.W.X squadron and its pilots, including Crenshaw, are recruited into the PMC Artemis Global Security.

We are testing : DX 10.1 with shadows high, sun shafts high, ambient occlusion (SSAO) very high. view distance high, forest high, environment high, texture quality high, HDR on, Engine heat on and DOF on.

The overclock on the HIS HD6870 Turbo boosts the framerates by around 5, helping it to outperform the MSI GTX460 Talon with this specific engine.

HQV Benchmark 2.0 is an updated version of the original tool and it consists of various video clips and test patterns which are designed to evalute motion correction, de-interlacing, decoding, noise reduction, detail enhancement and film cadence detection.

There are two versions of the program, standard definition on DVD and high definition on Bluray. As our audience will be concentrating on HD content so will we.

This has a total of 39 video tests which is increased from 23 in the original and the scoring is also up from a total of 130 to 210. As hardware and software gets more complicated, the software has been tuned to make sure we can thoroughly maximise our analysis.

To test power consumption today we are using a Keithley Integra unit and we measure power consumption from the VGA card inputs, not the system wide drain. The best way to get maximum load results is by using Furmark, and even though it is not indicative of a real world situation it shows the limits the card can theoretically demand. The ‘gaming’ results are measured when playing Crysis Warhead and is a more valuable result to take from this.

A very good set of results for the overclocked HIS HD6870 Turbo Edition, hovering around 125-130watts when gaming.

The tests were performed in a controlled air conditioned room with temperatures maintained at a constant 25c – a comfortable environment for the majority of people reading this.

Idle temperatures were measured after sitting at the desktop for 30 minutes. Load measurements were acquired by playing Crysis Warhead for 30 minutes and measuring the peak temperature. We also have included Furmark results, recording maximum temperatures throughout a 30 minute stress test. All fan settings were left on automatic.

The HD6870 is a reference design (with the standard AMD cooler) and as such we don’t expect wonderful results. The load results aren't bad, but we would expect this to drop when customised cooling solutions make their entrance onto the market.

Return to ambient is a feature we have recently added to our reviews … we measure the time it takes for a solution to return to idle temperatures, immediately after full load. The faster the time, the better the cooler – for example a Noctua NH D14 cooler will return an Intel processor to idle temperatures much faster than a reference cooler. This is a good indication of how quickly a heatsink can dissipate heat.

The HIS card is reasonably quiet, with their techs having focused on generating a reasonable cooling profile without causing much noise. The return to idle time is what we would expect with a reference cooler.

Recently we have changed our method of measuring noise levels. We have built a system inside a Lian Li chassis with no case fans and have used a fanless cooler on our CPU. We are using a heatpipe based passive power supply and an Intel SSD to keep noise levels to a minimum. The motherboard is also passively cooled. This gives us a build with completely passive cooling and it means we can measure noise of just the graphics card inside the system when we run looped 3dMark tests. Ambient noise in the room is around 20-25dBa. We measure from a distance of around 1 meter from the chassis and 4 foot from the ground to mirror a real world situation.

Why do this? Well this means we can eliminate secondary noise pollution in the test room and concentrate on only the video card. It also brings us slightly closer to industry standards, such as DIN 45635.

KitGuru noise guide
10dBA – Normal Breathing/Rustling Leaves
20-25dBA – Whisper
30dBA – High Quality Computer fan
40dBA – A Bubbling Brook, or a Refridgerator
50dBA – Normal Conversation
60dBA – Laughter
70dBA – Vacuum Cleaner or Hairdryer
80dBA – City Traffic or a Garbage Disposal
90dBA – Motorcycle or Lawnmower
100dBA – MP3 player at maximum output
110dBA – Orchestra
120dBA – Front row rock concert/Jet Engine
130dBA – Threshold of Pain
140dBA – Military Jet takeoff/Gunshot (close range)
160dBA – Instant Perforation of eardrum

When gaming, the card generates around 35dBA of noise, which rises to just under 40 dBA when running Furmark. The HIS card is slightly quieter than our reference design HD6870.

To overclock we used the Sapphire TRIXX software tool.

We managed to get another 70mhz from the core and another 55mhz (220mhz effective) from the GDDR5 memory. This earns the card another 500 points in 3DMARK Vantage and 3-4 extra frames in most of the leading engines at 1080p.

The HIS HD6870 Turbo is based around the reference AMD design and as such might not seem that exciting a proposition for many people, we are still waiting on custom cooled solutions which will reignite our excitement.

To be fair, the HIS Turbo Edition has proven to be the best HD6870 we have tested yet, not because of the relatively minor ‘out of the box' overclocks, but because we noticed a higher overclocking threshold, almost achieving 1ghz on the core. We aren't sure if HIS hand pick the Turbo cards from their production line, but clearly our review sample was better than the other five in our labs right now.

We are still impressed with the HD6870, especially in an overclocked state, because the levels of performance are close to the HD5870, which a year ago cost £100 more in the UK. There really has never been a better time to buy a video card as every sector is inundated with quality models.

Pricing for the HD6870 Turbo Edition a couple of days ago wasn't in such a healthy state, we noticed that UK stores were selling it for £40 more than the reference solution, which seemed over the odds for a card without a sexy cooler installed. After we flagged this to HIS directly however, the price dropped to £210 inc vat, which means you pay a £20 premium. We think this is fairly good value and while we can't verify that all Turbo Editions can hit 1ghz on the core it does appear that the overclocking thresholds are slightly better.

KitGuru says: HIS HD6870 Turbo is good bet if you want kick ass gaming performance at high resolutions.
