Intel Core i7 3820 and ASrock Extreme4-M review

Rating: 8.5.

Intel launched their X79 platform in November and Kitguru was on hand with multiple reviews. Since this launch we have looked at several motherboards primarily targeting the hardcore, high end overclocking audience. There is no doubt the Core i7 3960X Extreme Edition is the processor to rule them all, but at £850 inc vat it is out of reach for 95% of the audience reading this. For those on a more realistic budget, Intel are releasing the the Core i7 3820 for the X79 platform, a new Quad Core design at a much more reasonable price point … around £260.

To make the review more interesting today we decided to build an ultra high end media center using this new processor, The award winning Lian Li PC60 and the new ASRock Extreme4-M motherboard. Is this worth your money?

The Core i7 3820 is based on the Sandy Bridge E design which works on the LGA2011 platform, via motherboards already on the market. It supports Quad channel memory and 40 lanes of PCI Express which are capable of PCIe 3.0 speeds. The processor is also equipped with Hyperthreading, for a total of 4 physical and 8 logical cores.

The other product we are analysing today is the latest Micro ATX board from ASRock … the Extreme4-M based on the LGA2011 socket. This board may be small, but it is feature packed, with support for the latest range of Intel processors and Quad Channel 2400+ (OC) DDR3 memory. It is equipped with 3x PCIe 3.0 x16, SATA 3 and USB 3.0 ports and incorporates an advanced 6+2 Power Phase design with premium gold capacitors for long life and stability under stressful conditions.

We aim to build one of the fastest small form factor systems today, and even try our hand at overclocking.

The Intel Core i7 3820 is aimed at an X79 audience who have a limited budget. Currently we have the 3960X Extreme Edition, which retails for a whopping £850 in the UK, and the 3930k at a more realistic £500. The Core i7 3820 is a more modestly priced Quad Core solution targeted at the sub £300 sector.

The 3820 has 1.27 billion transistors and a die size of 294 mm2 which is smaller than the 3960X EE which has 2.27 billion transistors and a die size of 435mm2. The level 3 cache on the 3820 is 10MB, which is 5MB less than the flagship 3960X EE processor.

How does this compare against the current range of Quad Core processors for the P67 and Z68 platform?

Processor Core i7 2600k Core i7 2700k Core i7 3820
Cores 4 4 4
Base clock 3.4ghz 3.5ghz 3.6ghz
Turbo 3.8ghz 3.9ghz 3.9ghz
Cache 8MB 8MB 10MB
Memory Support Dual Channel Dual Channel Quad Channel

Our sample arrived without retail packaging, in a small black box.

Obviously, the 3820 is the same size as the 3960X EE, to fit into the LGA2011 socket. As expected, we received an engineering sample (ES).

System validation available here.

The Core i7 3820 is not a fully unlocked processor, unlike the 2500k and 2600k. The Core i7 3820 can be set to a maximum multipler that is four steps higher than the top turbo frequency. So we can therefore work out that it can run at 4.3ghz, 400mhz greater than the 3.9ghz top default turbo frequency (single core active). We will look at this more in the overclocking section of the review later.

The ASRock X79 Extreme 4-M arrives in an attractive, dark ‘metallic’ style finished box.

The bundle includes a couple of SATA cables, a comprehensive user manual, driver and software disc, SLI bridge and I/O backplate.

The Extreme4-M may be small, but it is very menacing looking, finished in dark brown with black ports and silver accented heatsinks. It is actively cooled on the Southbridge, like other ‘full sized’ X79 boards we have reviewed recently. It is a Micro ATX board, measuring 9.6-in x 9.6-in, 24.4 cm x 24.4 cm.

There are a total of four DDR3 memory slots, for Quad Channel memory configurations. It supports speeds of 800/1066/1333/1600/1866/2133/2400mhz with a maximum capacity of 32GB. You would need to purchase 8GB DIMMS however, which are still very expensive. There is also full support for XMP 1.2 and 1.3 memory profiles.

The board is populated with Japanese made conductive polymer capacitors, these are premium gold caps. The 8 pin CPU power plug is very close to the memory slots, as shown above. It doesn’t cause any installation problems however.

Despite the small dimensions, the board literally crams in fan headers, seven in total, spread across the four corners of the PCB. This is the same as the Extreme 4 motherboard actually, which is impressive.

The board includes three 16x PCI-E 3.0 slots, two of which are 16x bandwidth rated. The third is limited to 8x. There is also a PCI slot at the bottom which may prove useful for people with older sound cards. It has full support for Quad CrossfireX and Quad Sli configurations.

The board has a total of 7 SATA ports. The four black ports are SATA 2 rated (3Gbps – Intel X79 chipset controlled). The three grey ports are SATA 3 rated (6GBps). One of the grey ports is vertically mounted for front panel chassis connection. The 2x grey SATA 3 connectors are controlled by the Intel X79 chipset (Raid 0, 1, 5 and 10 support) and the single connector is powered by the ASMedia ASM1061 processor.

At the bottom of the board is a diagnostic readout, and a power and reset button, for quick, easy access.

I/O Panel has the following ports:

  • 1 x PS/2 Mouse Port
  • 1 x PS/2 Keyboard Port
  • 1 x Coaxial SPDIF Out Port
  • 1 x Optical SPDIF Out Port
  • 6 x Ready-to-Use USB 2.0 Ports
  • 1 x eSATA3 Connector
  • 2 x Ready-to-Use USB 3.0 Ports
  • 1 x RJ-45 LAN Port with LED (ACT/LINK LED and SPEED LED)
  • 1 x IEEE 1394 Port
  • 1 x Clear CMOS Switch with LED
  • HD Audio Jack: Side Speaker / Rear Speaker / Central / Bass / Line in / Front Speaker / Microphone

On this page we present some super high resolution images of the product taken with the 24.5MP Nikon D3X camera and 24-70mm ED lens. These will take much longer to open due to the dimensions, especially on slower connections. If you use these pictures on another site or publication, please credit Kitguru.net as the owner/source.

ASRock are using a fully featured UEFI style interface for the Extreme4-M, which is intuitive and loaded with plenty of settings for overclocking.

The advanced tab offers many settings to give the user control over the hardware. The hardware monitoring tab shows real time views of voltages, temperatures and fan settings.

The boot menu is easy to navigate and allows for control over the hard drives and SSD drives and the boot priority. The full screen boot logo can be disabled (always a must).

The ASRock board has some very handy pre-built overclocking settings as shown above. Unfortunately as we mentioned earlier the Core i7 3820 is not a fully unlocked processor, unlike the 2500k and 2600k. The Core i7 3820 can be set to a maximum multipler that is four steps higher than the top turbo frequency. So we can therefore work out that it can run at 4.3ghz, 400mhz greater than the 3.9ghz top default turbo frequency (single core active).

This is when the bios gets slightly confusing, because if you use one of the preconfigured bios overclocked settings in the ‘EZ OC’, it will actually show a ratio above 43, such as 46 for 4.6ghz. The bios will even report a successful overclocked speed, after reboot. It unfortunately is limited to 4.3ghz via a 43x ratio as CPU-z in Windows will verify. If the user tries to manually overclock, bypassing the EZ OC menu it is correctly limited to 43.

If you are happy running a beta bios ASrock updated to V1.62 which resolves this particular problem.

Some motherboards have ‘straps’ which act as a multiplier on the base clock (such as 1.25x or 125mhz). This could push the overclocking results even further.

We tested with some Corsair GTX8 2,400mhz rated DDR3 which we used in our launch article for the Asus IV Rampage Extreme Edition.

Sadly we couldn’t get the memory to post at 2,400mhz, regardless of settings. We did get it to run at 2,133mhz without any problems.

The ASRock bios offers many voltage settings which allow the processor to be overclocked further. Using a BCLK setting of 105 at the maximum ratio,

Using modest air cooling with only a very slight core voltage increase we managed to get the system overclocked and stable at 4.5ghz. Validation is available here. We could probably push further with more advanced cooling and higher voltage but these are great results for a Micro ATX board.

The HD7970 is a powerful video card and the performance is as good as would expect and slightly higher than we achieved with the Sapphire X79 motherboard we tested recently.

SiSoftware Sandra (the System ANalyser, Diagnostic and Reporting Assistant) is an information & diagnostic utility. It should provide most of the information (including undocumented) you need to know about your hardware, software and other devices whether hardware or software.

Sandra is a (girl’s) name of Greek origin that means “defender”, “helper of mankind”. We think that’s quite fitting.

It works along the lines of other Windows utilities, however it tries to go beyond them and show you more of what’s really going on. Giving the user the ability to draw comparisons at both a high and low-level. You can get information about the CPU, chipset, video adapter, ports, printers, sound card, memory, network, Windows internals, AGP, PCI, PCI-X, PCIe (PCI Express), database, USB, USB2, 1394/Firewire, etc.

Native ports for all major operating systems are available:

  • Windows XP, 2003/R2, Vista, 7, 2008/R2 (x86)
  • Windows XP, 2003/R2, Vista, 7, 2008/R2 (x64)
  • Windows 2003/R2, 2008/R2* (IA64)

  • NUMA – Non-Uniform Memory Access
  • AMD64/EM64T/x64 – 64-bit extensions to x86
  • IA64 – Intel* Itanium 64-bit

Great all round performance, at the same level as the 2700k, except in the memory bandwidth test where it is significantly faster, falling in behind the Intel Core i7 3960X system at almost 40 GB/s.

CINEBENCH R11.5 64 Bit is a real-world cross platform test suite that evaluates your computer’s performance capabilities. CINEBENCH is based on MAXON’s award-winning animation software CINEMA 4D, which is used extensively by studios and production houses worldwide for 3D content creation. MAXON software has been used in blockbuster movies such as Spider-Man, Star Wars, The Chronicles of Narnia and many more.

CINEBENCH is the perfect tool to compare CPU and graphics performance across various systems and platforms (Windows and Mac OS X). And best of all: It’s completely free.

The Core i7 3820 running on the ASRock Extreme4-M motherboard falls in between the Core i7 2600k and the Core i7 2700k, scoring 7.19 points. When overclocked to 4.5ghz, it scores 8.79 points, falling in behind the reference clocked Intel Core i7 990X Extreme Edition.

Crystalmark is a useful benchmark to measure theoretical performance levels of hard drives and SSD’s. We are using V3.0.1 x64.

Performance figures are as good as we have seen from the Pyro 240GB SE SSD, scoring around 500 MB/s in both the sequential read and write tests. 4K performance is brilliant.

The ATTO Disk Benchmark performance measurement tool is compatible with Microsoft Windows. Measure your storage systems performance with various transfer sizes and test lengths for reads and writes. Several options are available to customize your performance measurement including queue depth, overlapped I/O and even a comparison mode with the option to run continuously. Use ATTO Disk Benchmark to test any manufacturers RAID controllers, storage controllers, host adapters, hard drives and SSD drives and notice that ATTO products will consistently provide the highest level of performance to your storage.

Strong performance from the ASRock motherboard, scoring 560 MB/S in the sequential read test and around 530 MB/s in the sequential write test. As good as we have seen from this particular drive.

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.

We created a new 8200×3200 scene and recorded the time for the hardware to finalise the render.

The Quad Channel memory architecture shows benefits with this specific test, delivering a time six seconds faster than the Core i7 2700k. When overclocked to 4.5ghz, the time is reduced to 6 minutes and 22 seconds which is around 11 seconds slower than the reference clocked Core i7 990X Extreme Edition.

CyberLink MediaEspresso 6 is the successor to CyberLink MediaShow Espresso 5.5. With its further optimized CPU/GPU-acceleration, MediaEspresso is an even faster way to convert not only your video but also your music and image files between a wide range of popular formats.

  • Online Sharing – Conversion to video formats used by popular social networking websites and a direct upload feature means posting videos to Facebook and YouTube has never been easier.

For our testing today we are converting a 3.3GB 720p MKV file (2h:12mins) to Apple Mp4 format for playback on a portable device. This is a common procedure for many people and will give a good indication of system power. We are using the newest version which has been optimised for Sandybridge processors.

Again, the Quad Channel memory architecture shows huge benefits with this video encoding software, completing the test in 10 minutes and 15 seconds, around 17 seconds faster than the Core i7 2700k. When we overclock the 3820 to 4.5ghz, the system is actually faster than the last generation flagship Core i7 990X system, and equals the reference clocked 3960X EE system. It is worth pointing out that this particular test doesn’t utilise all cores @ 100%.

Our good friends at Cyberlink kindly supplied the software for our BluRay and conversion tests.

Cyberlink PowerDVD 11 is one of the finest solutions for the BluRay experience on Windows and we found this software to work perfectly with this chipset. We tested with the new Bluray Disc of ‘The Road’.

These results are roughly equivalent to the 2600k, demanding 0.2% less CPU time.

Many people using this system will be enjoying Flash related content so we feel it is important to test with some of the more demanding material available freely online.

Close to the 2600k again, averaging 7.2% this time.

Handbrake is a fantastic free program which we wanted to include to confirm findings with Media Espresso, earlier in the review. HandBrake is an open-source, GPL-licensed, multiplatform, multithreaded video transcoder, available for MacOS X, Linux and Windows.

We used the latest V 0.9.5 for testing today across all platforms. We encoded an DVD.MPG file.

The memory bandwidth reaps rewards with this specific test. The 3820 is around 7 seconds faster than the 2700k at default clocks and is only 8 seconds slower than the reference 990X EE when overclocked to 4.5ghz.

F1 2011 is the newest Direct X 11 racing game from industry pioneers CodeMasters. The 2011 Formula One season is the 62nd FIA Formula One season. The original calendar consisted of twenty rounds, including the inaugural running of the Indian Grand Prix before the cancellation of the Bahrain Grand Prix. Pirelli returns to the sport as tyre supplier for all teams, taking over from Bridgestone. Red Bull Racing are the reigning Constructor’s Champions. Red Bull Racing’s Sebastian Vettel is the defending Drivers’ Champion, one of five World Champions appearing on the grid.

The system averages just under 80 fps at these settings, which is an excellent result.

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, taking place ten years after the events of the first game, on the same fictional planet. We don’t really enjoy playing this game, but the engine is a great Direct X 11 test of modern hardware.

Another great set of results, averaging 66 fps at these high settings, while maintaining frame rates above 40 at all times.

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 comparable throughout reviews.

No problems powering through this title, averaging 180 fps in Crossfire.

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.

Settings: 1920×1200, D3D10, Disable Artificial Intelligence(No), Full Screen, Anti-Aliasing(8x), VSync(No), Overall Quality(Ultra High), Vegetation(Very High), Shading(Ultra High), Terrain(Ultra High), Geometry(Ultra High), Post FX(High), Texture(Ultra High), Shadow(Ultra High), Ambient(High), Hdr(Yes), Bloom(Yes), Fire(Very High), Physics(Very High), RealTrees(Very High).

A demanding title, but no problems for this system, averaging around 185 fps.

We are measuring power drain at the wall, excluding the monitor and focusing just on the system. For load tests, we run Cinebench R11.5 64 bit.

Power efficiency is good, but slightly worse than the Core i7 2600k, both when idle and when at full load. The FX8150 leads the pack here, in the test it actually won’t want to lead!

The Intel Core i7 3820 is launched to target the audience who want the benefits of the X79 platform without having to spend £850 for a Core i7 3960X Extreme Edition, or £500 for a Core i7 3930. We haven’t been given official prices yet, but insiders have told us that the 3820 will cost around £260 when it hits the United Kingdom, and should be released shortly.

We have been extremely impressed with the performance from Intel’s 3820 and the system felt just as fast as the last 3960X EE system we built for general duties and even gaming. The performance is enhanced by the Quad Channel memory architecture, which is a significant improvement when compared against the P67 and Z68 platform’s dual channel configuration.

For gaming duties, we didn’t notice much in the way of a tangible difference between the Core i7 3820 system and the Core i7 2600k/2700k rigs, but if you also encode video or render 3D scenes on a regular basis, then the new architecture has benefits as shown with some of the results today. Improvements were easily noticeable with 3D Studio Max 2011, Media Espresso and Handbrake.

Overclocking proved a positive experience, and the ASrock Extreme4-M is a fully loaded loaded Micro ATX board which suffers very few compromises. Achieving 4.5ghz required minimal work and more should be possible with better cooling than we used in our Lian LI PC60 chassis. That said, the hardcore overclocking audience will be slightly disappointed to see that unlike the 2500k, 2600k and 2700k the new chip is partially locked, limited to a ratio of x43. QuickSync and integrated graphics are not supported, which may prove a problem for a small portion of the audience.

For those people who already own a high performance 2700k, 2600k or 2500k system, the move to a 3830 X79 system will be expensive. Unless you really need Quad Channel memory, and the benefits of improved future proofing it may be a hard sell.

If you are in the market for a new system build and want to move to the X79 platform, then the 3820 is a fairly cost effective solution. The biggest issue would be the price of the motherboards, which are often in the region of £250, around the same price as the processor itself. The ASrock Extreme4-M we reviewed today is cheaper than most, being sold on Scan for £170 inc vat, offering good value for money. It also means you can look at a variety of Micro ATX cases, if you fancy downsizing without compromising. We have no hesitations recommending the Extreme4-M, it didn’t cause us a problem over a week of stress testing and delivers fantastic discrete graphics performance, as highlighted with our HD7970 and HD7970 Crossfire results today.

Both Intel Core i7 3820 and Asrock Extreme4-M earn our ‘WORTH BUYING’ award, scoring 8.5/10. The Core i7 3820 may not be an ideal investment for gamers who already own a high performance 2600k or 2700k system, but for those building a new system from scratch and who want access to the X79 architecture then the system we built today is very stable, overclocks well and more importantly doesn’t cost a fortune.

Kitguru says: We managed to build an ultra high performance system in a small form factor Lian Li case today. A 3820 and ASRock Extreme4-M is a powerful foundation for a system that doesn’t cost the earth.
