Sapphire RX 470 Nitro + OC 4GB Review

650px12.jpg
Rating: 7.0.

Yesterday AMD launched their new RX 470 graphics card, and we were on hand to cover the Asus Strix Gaming OC solution. Today we take a look at the new Sapphire RX 470 Nitro + OC 4GB which features a custom dual fan cooler with enhanced core and memory clock speeds.

This Sapphire RX 470 Nitro+ OC card looks very like their higher end models that we have reviewed in recent months, which is not a bad thing. Its a dual fan solution with thick heatpipes visible close to the PCIe connector.

An overview of the Ellesmere RX 470 in GPUz. AMD's RX 480 has 2,304 stream processors, the RX 470 has 2,048. Both have 32 ROPS, however the RX470 loses 16 texture units, from 144 on the RX 480 to 128 on the RX 470.

The Sapphire RX 470 Nitro + OC card has has both core and memory overclocked. The core is running at 1260mhz, and the memory is running at 1,750mhz (7Gbps effective). This is 10mhz less than the Asus version of the RX 470, although Asus didn't overclock the GDDR5 on their card.

While AMD told me in email that they could not confirm 8GB RX470's would be available it would appear that MSI have already released a version. I received one a few hours ago and its in my test bed as we speak and I plan on publishing that review as soon as I can. I am currently chasing the price of this 8GB model, because with 4GB RX470's only £10 less than 4GB RX480's it would appear that an 8GB RX470 could actually cost more than a 4GB RX480. What a bizarre launch this has turned out to be.

The Sapphire RX 470 Nitro + OC 4GB arrives in a thin long box featuring artwork of a robot on the front.

L1000648

A little background history on Sapphire and some product features populate the rear of the box.

L1000650L1000651

Inside the small box is the card, alongside a software disc and some literature on the product. We recommend to always get the drivers direct from the AMD website as they are updated every month with new performance improvements and bug fixes.

L1000654L1000656

The Sapphire RX 470 Nitro + OC 4GB is a subdued, but attractive looking graphics card. The front is plain black, but the rear is equipped with a very tasty looking custom backplate. The Asus RX 470 Strix Gaming OC Aura was NOT equipped with a backplate which seems like an oversight to me.

L1000659

The card takes power from a single 8 Pin PCIE connector.

L1000662

A V Bios switch and LED mode button are placed closely together at the other side of the card.

The I/O plate is fitted with a single DVI (Dual link) connector, two HDMI (2.0) connectors, and two DisplayPort (1.4) connectors.

There are a lot of screws on the Sapphire cards. The cooler is mounted via a series of screws and fan headers. The heatsink can then be seen clearly mounted to the PCB. When the cooler is removed, we can see two thick heatpipes running into two large aluminum fins on either side of the copper core. The memory and VRMs are also cooled by the heatsink system above.

Sapphire are using SK Hynix GDDR5 memory on the card. The card is equipped with 5 GPU power phases and 2 memory power phases.

The upcoming TriXX 3.0 software tool from Sapphire has control options for the lighting on the card. We don't have the final version of the software yet, so we can't really go into any detail.

I have spent the last month benchmarking a selection of AMD and NVIDIA cards with the latest drivers on one of our new 6700k test beds. We are using the AMD Crimson Edition Display Driver, Version 16.8.1 and Nvidia ForceWare 368.81 driver.

We list each resolution test for every game on its own page – meaning if you are just interested in 1440p resolutions for instance, you can skip the other resolutions without effort. If you want to read the whole review and find all the page changes annoying – click on our menu system top right of these pages, and head to ’32. view all pages’.

We are aware the RX 470 is not designed for Ultra HD 4k gaming, but we include the results out of the sake of being thorough. There is also the possibility that if AMD do release an 8GB version of the RX 470, we will want to test it against the 4GB version at higher resolutions. Even if it seems somewhat pointless in the grand scheme of things.

We are using a custom Titan Bayonet system supplied by Overclockers UK as the basis of our test system today. Read more on this system over HERE.

The Sapphire RX 470 Nitro + OC averages 45 frames per second, which places it just behind the reference AMD RX 480 and ahead of the Palit GTX 970.

Ashes of the Singularity is a real-time strategy game set in the future where descendants of humans (called Post- Humans) and a powerful artificial intelligence (called the Substrate) fight a war for control of a resource known as Turinium.

Players will engage in massive-scale land/air battles by commanding entire armies of their own design. Each game takes place on one area of a planet, with each player starting with a home base (known as a Nexus) and a single construction unit.

We noticed that the Sapphire RX 470 Nitro + OC was holding a very high clock speed at all times, which actually gave it a slight edge (less than a single frame per second) over the reference RX 480. It was rare however to see this card outperform the reference RX 480. It just goes to show what a great cooling solution (against a rubbish one fitted to the reference RX 480) can do for performance.

Very closely matched against the AMD RX480, due to the high constant clock speeds of the Sapphire card.

Middle-earth: Shadow of Mordor is a third-person open world video game, where the player controls a ranger by the name of Talion who seeks revenge on the forces of Sauron after his family, including his wife, are killed. Players can travel across locations in the game through parkour, riding monsters, or accessing Forge Towers, which serve as fast travel points.

Dirt Rally is developed by British video game developer Codemasters using the in house Ego engine. Development began with a small team of individuals following the release of their 2012 video game Dirt: Showdown. Codemasters have emphasised a desire to create a simulation with Dirt Rally. They started by prototyping a handling model and creating tracks based on map data. The game employs a different physics model from previous titles, rebuilt from the ground up.

The GTX 970, 380X and RX 470 cannot maintain smooth frame rates with these settings at 4K. You could dial down a lot of the image quality settings to get above 30fps, but spending more cash would be advised.

Rise of the Tomb Raider is a third-person action-adventure game that features similar gameplay found in 2013's Tomb Raider. Players control Lara Croft through various environments, battling enemies, and completing puzzle platforming sections, while using improvised weapons and gadgets in order to progress through the story. It uses a Direct X 12 capable engine.

No chance of being able to get a smooth gaming experience at 4K – not unless we opted for one of the lowest image quality profiles in the options. Still we can see the Sapphire card holds its own against the GTX 970 from the last generation.

Grand Theft Auto V is an action-adventure game played from either a first-person or third-person view. Players complete missions—linear scenarios with set objectives—to progress through the story. Outside of missions, players may freely roam the open world. Composed of the San Andreas open countryside area and the fictional city of Los Santos, the world is much larger in area than earlier entries in the series. It may be fully explored after the game's beginning without restriction, although story progress unlocks more gameplay content.

4K is not the resolution of choice for a RX 470, but with the 8GB versions of the cards that we are testing now, it will be interesting to see if the extra memory will make any difference at all at higher resolutions.

Just like the original game Metro 2033, Metro: Last Light is played from the perspective of Artyom, the player-character. The story takes place in post-apocalyptic Moscow, mostly inside the metro system, but occasionally missions bring the player above ground. Metro: Last Light takes place one year after the events of Metro 2033, following the canonical ending in which Artyom chose to proceed with the missile strike against the Dark Ones (this happens regardless of your actions in the first game). Redux adds all the DLC and graphical improvements.

‘I'll have an overclocked GTX 1080 please!', said every gamer who wants to play Metro at 4K. The Sapphire RX 470 is completely out of juice at these settings. Again these are just included for curiosity, and also to compare against 8GB versions of these cards which are just hitting our labs this week.

Hitman (2016) is a third-person stealth video game in which players take control of Agent 47, a genetically enhanced, superhuman assassin, travelling to international locations and eliminating contracted targets. As in other games in the Hitman series, players are given a large amount of room for creativity in approaching their assassinations. The game is being released in stages, which hasn't proved too popular with a large audience.

We test with many of the settings maximised, SSAO is disabled however as I found it causes some crashing. I have to say that Hitman is a little unstable at times under the best of situations, but we managed to get it running well enough to benchmark. The built in benchmark is very flaky indeed however, so real world runs had to be used.

At Ultra HD 4k resolutions the Sapphire RX 470 Nitro + OC struggles to maintain playable frame rates. This is not the ideal card for super high resolutions, however with AMD partners releasing 8GB versions, we will be interested to see how they compare.

We have built a system inside a Lian Li chassis with no case fans and have used a fanless cooler on our CPU. The motherboard is also passively cooled. This gives us a build with almost completely passive cooling and it means we can measure noise of just the graphics card inside the system when we run looped 3dMark tests.

We measure from a distance of around 1 meter from the closed chassis and 4 foot from the ground to mirror a real world situation. Ambient noise in the room measures close to the limits of our sound meter at 28dBa. 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.

The fans disable at idle and lower power demands, which is a great feature to have. When load increases, the fans spin up to around 1,350 rpm when gaming, and 1,650 rpm when running FurMark. The fans are quiet under load.

We didn't hear any coil whine either, which is positive to note.

The tests were performed in a controlled air conditioned room with temperatures maintained at a constant 21c – 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 Rise Of The Tomb Raider for 90 minutes and measuring the peak temperature. We also have included Furmark results, recording maximum temperatures throughout a 10 minute stress test. All fan settings were left on automatic.

Sapphire are opting for a less aggressive profile, holding a thermal profile around 75c. When gaming the card holds the temperature steady at 72c. This rises a little further when pressed hard with the synthetic FurMark software test.

thermals

With the backplate installed the temperatures hold steady around the 50c mark under load. There are no hotspots across the PCB which is good to see.

We measure power consumption from the whole system when idle and when gaming, excluding the monitor. We play Rise Of the Tomb Raider and measure demand.

power consumption

Power consumption from the system showed around 234 watts, very similar against the Nvidia GTX 970.

We overclocked the Sapphire RX470 Nitro+ OC with AMD's Wattman. We did have a very early beta version of Sapphire's StriXX tool but we aren't allowed to show any screenshots of it yet, as the user interface is not finished.

overclocking

ocspeeds

Using the overclocking software I was able to get the Sapphire RX 470 Nitro+ OC to a core speed of 1,400mhz which is very good. The memory was stable at the maximum available setting of 1,800mhz.

The Sapphire RX 470 Nitro + OC 4GB is another well built card from AMD's leading GPU partner. We really didn't expect anything less.

Asus may have removed the backplate from their Strix version of the RX 470 but Sapphire decided it was important enough to keep. Our thermal imaging camera proved that Sapphires implementation eliminated PCB hot spots while the Asus card was running 28c hotter in positions close to the VRM's. It was a good decision by Sapphire to keep the backplate.

Sapphire also opted for a less aggressive fan profile and a higher thermal temperature profile, set at 75c. Due to this we noticed that the Sapphire RX 470 Nitro+ OC 4GB held a higher clock speed than the Asus RX 470 Strix under load, even though the Strix was actually clocked 10mhz higher. It is worth pointing out that Sapphire are the only partner at this point who have also overclocked the GDDR5 memory. This gives a minor boost to frame rates.

Unfortunately for Sapphire, they are the same victims of pricing concerns that I discussed in detail in KitGuru's Asus RX 470 Strix OC review also published today. This Sapphire RX 470 Nitro + OC will be priced at £188.99 inc vat on Overclockers UK making it £11 less expensive than Sapphire's own, faster RX 480 Nitro + OC. It's a fairly ludicrous market situation to be discussing and one that has caused much head scratching in the last week.

Is there is any reason to buy the Sapphire RX 470 Nitro + OC over the RX 480 Nitro + OC which we reviewed on July 27th (HERE)? Honestly, I can't find any. The RX 470 has 16 less texture units and 256 stream processors have been disabled. I think paying £11 to get those back is a worthwhile expenditure, especially when noise levels and cooling performance are basically identical between the solutions. Sapphire don't incorporate weak cooling solutions on any of these cards.

In the build up to launch today I have been talking with Sapphire, AMD and leading etail partners such as Overclockers UK trying to get my head around the price points. Unfortunately pricing is such a critical concern in this sector that it completely changes my recommendations.

sapphire reference RX 470

We have been told that while these Nitro+ OC RX 470's are expensive there will be some cheaper ‘reference style' RX 470 options available. Sapphire for instance are releasing a reference design RX 470 for £164.99 inc vat. The clocks are set at 932mhz base, 1,216mhz boost with 7000mhz GDDR5. It is equipped with a single fan (dual ball bearing) reference style AMD blower cooling system (see image above). We can't comment on how good, or bad this version is, as we have only been sent the Nitro+ OC version of the RX 470. If you are further restricted in budget to £170, then this cheaper reference design is probably a decent option, but I need to raise a few concerns over potential noise levels and perhaps even some thermal throttling.

For me, this has been a rather disappointing, disorganised launch from AMD. Both Sapphire Nitro+ OC and Asus Strix RX 470 cards are fine implementations of a sub £200 gaming solution, but with the faster 4GB Sapphire RX 480 Nitro+ OC available at £199 there really is only one card we can recommend to readers with a £200 budget.

Next up, I will be looking at some 8GB versions of the RX 470, which are actually more expensive than the Sapphire RX 480 Nitro+ OC 4GB.

I was told two days before this launch directly by AMD that they couldn't comment on whether an 8GB RX 470 even existed, and within a few hours time, I had one on my lap, delivered straight from Asia by MSI. Yes, AMD wouldn't confirm the existence of a card that I had on my desk in front of me, supplied by one of their partners. AMD PR has been so utterly ill informed throughout this entire launch that I actually wonder if they communicate at all internally.

You will be able to buy the Sapphire RX 470 Nitro + OC 4GB from Overclockers UK for £188.99 inc vat. Our honest advice is to spend the extra £10 to get the Sapphire RX 480 Nitro+ OC 4GB instead. It is a more powerful card well worth the marginal increase in price.

Pros:

  • great build quality.
  • dual fan cooler works well.
  • no coil whine.
  • backplate.
  • quiet.
  • good overclocking headroom.

Cons:

  • The superior Sapphire RX 480 Nitro+ OC is only £11 more.

Kitguru says: The Sapphire RX 470 Nitro + OC 4GB is a card that performs well at 1080p. The price point would be more acceptable if Sapphire's own RX 480 Nitro+ OC 4GB wasn't just £10 more. You get more texture and shader power for half the price of a Domino's pizza.
