Review of AMD ATI Radeon HD 5670 512MB Graphics Card

INTRODUCTION

The first member of the Evergreen family hit the market back in September (2009). AMD has since then not said much about what would follow.

AMD chose to release the 5670 card at last week's CES 2010 event. The 5600 series chip is called Redwood and currently only includes the Radeon HD 5650 and 5670 chips. The 5600 series is clearly directed to the mid range segment of the market as illustrated in AMD's release strategy below. AMD has release two versions of the HD 5670 card, one with 1GB GDDR5 and another with 512MB GDDR5. This review covers the latter one.

The 5600 series adopts the technologies of its big brothers like ATI Stream and ATI Eyefinity. Here are AMD's own words about their new "ATI Stream" technology:

ATI Stream technology is a set of advanced hardware and software technologies that enable AMD graphics processors (GPUs), working in concert with the system's central processors (CPUs), to accelerate enabled applications beyond traditional graphics and video processing. This enables balanced platforms to run computationally-intensive tasks more efficiently, providing a better application experience to the end user. The 5600 series also has full support for Microsoft's DirectX11 API. I guess most people buying a graphics card in the middle range segment don't really know what the big deal is but anyone interested in the GPU industry knows that if you want to see the latest innovations in gaming you want to be on the latest DirectX train.

ENGINEERING SPECIFICATIONS

The test sample I will be reviewing today is a generic AMD ATI Radeon HD 5670 512MB GDDR5. It is a pre production unit which AMD sends out to selected publications before other outfitters' versions hit the store shelves. I am actually a bit late out with my review, but hey, what's the hurry anyway?

Here are the specifications for the HD5670 512MB GDDR5:

AMD ATI Radeon HD 5670 512 MB GDDR5 GPU Redwood (Radeon HD 5670) Transistors 627 Ms GPU Speed 775 MHz Stream processors 400 Performance calculation 620GFLOPS Texture units 20 Texture fill rate 25.2 GTexels/s ROPs 16 Pixel fill rate 6.2 Gpixel/s Z/Stencil 24.8 GSamples/s Type of memory GDDR5 Speed of memory 1000 MHZ Amount of memory 515MB Bandwidth of memory 64 GB/s Bus width 128-bit Consumption Normal (61W)/IDLE (14W)

IN DETAIL:

I'm not going to spend too much time rambling about what the card looks like since most outfitters will be mounting their own cooling solutions. In short however, the card has a one slot cooler which is great and expected with a middle range card.

The card is manufactured with a 40nm technology which is great since it will increase its energy efficiency and decrease the generated heat in relation to performance.

A good thing about the fact that this card is fairly small and thin is that it fits in smaller cases suitable for HTPC and media PC projects. The length of the Radeon HD 5670 is 170mm.

The card has no PCI- Express power connector which should be considered as something positive I guess. It means that the card will never draw more power than what the PCI-Express bus can handle.

The 5670 generic card has 3 connectors; a Display Port; a HDMI and a DVI connector. It supports the "ATI Eyefinity" technology which means you can use monitors on each connector simultaneously. The HMDI connector support s HDMI 1.3a which means full support for Dolby True HD and DTS Audio Masters.

TEST SYSTEM I used my normal test system for this review, here are the specs:

Test equipment Processor Intel Core i7 920 Fan Prolimatech Mega Shadow Motherboard Asus Rampage II Gene Graphics card ATI Radeon HD 5670 512MB GDDR5 Soundcard Integrated Memory 3 x2 GB GSkill Trident 1600 MHZ (6-7-6-18) Hard disk Intel X25-M G2 Postville 80 GB Power supply Corsair HX850W

Operating system and software Operating system Windows 7 64bits System dirvers Controller 8.69_RC3 (BETA) DirectX August 2009 Benchmarking software 3D Mark 06 3D Mark Vantage Furmark 1.7 Unigyne Heaven Benchmark Games The Last Remnant Street Fighter IV Resident Evil 5 Weak May Cry 4 S.T.A.L.K.E.R. Clear Sky S.T.A.L.K.E.R. Call of Prypiat DIRT 2 Far Cry 2 Crysis Warhead Other software CPU-Z 1.49 GPU-Z 0.3.7 OCCT 3.1

During my test I set the in-game graphics settings to the highest quality. I set the filter settings to "medium" because of the fact that this card is not intended for people who "must" have the filter settings to max.

For those of you who are not too familiar of how to measure the performance of a graphics card, here's a table with frame rate numbers and what they actually mean in real life gaming experience:

FPS (Frames per second) FPS lower than 30 Not a good gaming experience 30 - 40 FPS OK but not good gaming experience 40 - 60 FPS Good gaming experience Higher than 60 FPS Excellent gaming experience

I always do the tests with the benchmarking software first because it often gives a glint of the overall performance of the card. In this case the results tell me that the performance of this card is a bit above what I had expected from a medium range card in the new AMD generation.

As a comparison a Nvidia GT 240 GDDR5 card I have tested in the same system obtained around 7000 points in 3DMark 2006 and in my last review of a GT220 card (a card more towards the lower end segment) it achieved 6700 points. The Radeon HD5670 card came in at 11700 points which exceeds the NVIDIA cards by quite a lot.

As I have experienced with all the DirectX11 compatible cards I have reviewed, the performance diminishes with the jump from DirectX10 to DirectX11. This is strange because "higher performance" is one of the major selling points with the new API from Microsoft.

The Radeon HD 5670 actually turns out to be even more powerful in the first batch of games that I had expected based on the results achieved in the benchmarking tests. I was actually somewhat surprised that this medium range card, at a price level below $100, could move these games with great fluidity.

Games like The Last Remnant, Street Fighter IV and Devil May Cry 4 actually ran really well no matter what level of graphics quality setting, resolution or filter I set. Even Resident Evil 5 ran OK

A strange thing about the results above is the case of the games STALKER: Clear Sky and STALKER: Call of Prypiat. The first one uses DirectX10 and the second DirectX11. STALKER Clear Sky (DX10) offers a very limited gaming experience while STALKER: Call of Prypiat (DX11) has much better results. I mean, those games are part of the same series. It raises questions like: is DirectX11 more efficient than DirectX10 after all? Or; do these two games have different 3D motors? I am afraid I cannot answer those questions for you, just thought that I'd bring it to your awareness.

There are however clearly two games in this batch which this card cannot handle; Far Cry 2 and Crysis Warhead. The performance of the Radeon HD 5670 in Far Cry 2 at a resolution of 1680×1050 (without filters) at 41.04 FPS just isn't good enough and far from the results I achieved with the Sapphire HD 5750 (61.57 FPS).

Still, the Radeon HD 5670 demonstrates a remarkable performance in very demanding games. If we can live with not always running the games in the highest resolutions with filters enabled, then you will not be disappointed.

HD VIDEO

In order to analyze the performance of the Radeon HD 5670 when replaying HD video I measured the average CPU load (%) during a 5 minute period while playing HD content. I did the measurements in two resolutions: 720p (H.261) and 1080p.

The excellent results are really thanks to the ATI Steam technology. It is great to see such a powerful card with such small dimensions. It makes the card ideal for a HTPC.

OVERCLOCKING, COOLING AND CONSUMPTION

Overclocking is always exciting (at least for me) but I wasn't overly enthusiastic about this card since all I had to work with was the ATI Catalyst application. I did however reach a decent 9% increase of the GPU (775 MHz) and a 9.5% increase of the original memory frequency. This was the max numbers I could set in the ATI Catalyst application which leaves some room for other outfitters to unlock a greater overclocking.

The cooling system of this card fulfills its task. We must consider that is just a generic sample of the card so none of the outfitters fancy cooling solutions are present. The temperatures that you see in the graph below at full load are high but they are actually what I usually see with a new reference model AMD ATI card. We will just see what the different outfitters can come up with in terms of cooling solutions for the 5670 chip and what they can do with the temperatures.

The fan is automatically regulated and its rotation speed is around 28% when the card is in idle mode. Below 40% the fan is imperceptible but above 50% it is perfectly audible without ever getting as annoying as fans on high end cards.

The use of the new manufacturing technology at 40nm gives this card a better efficiency ratio than previous generation of graphics cards. In the real world this means an improvement of the performance at the same power consumption levels. Or the other way around; a lower power consumption at the same performance level. According to AMD ATI, the idle mode consumption should be 14W whereas the typical consumption in operation is at 61W.

I measured the total power drainage of my system in idle mode and overclock mode which is illustrated in the graph below. I cannot tell you if AMD ATI's number are correct or not.

RESULTS OF THE TEST WITH OVERCLOCK

The results tells us a slight increase of the performance. For instance the gain in Crysis Warhead was around 1.5 FPS and in Far Cry 2 the increase was around 3 FPS. In reality this doesn't mean much.

CONCLUSIONS

OK, so this card is clearly not a high end gaming card, but the big question is if it's powerful enough to be of any use for us gamers? I would say definitely yes! If you can accept playing FPS games without filters you will be satisfied with this card. Hard core gamers will however have to go for the next price level.

What is great with this card is that AMD has managed to squeeze in all the new technologies which we saw in the 5800 series, like the ATI Steam, DirectX11 and ATI Eyefinity. That fact combined with the fact that this card is quite small makes it ideal for anyone looking for a graphics card for HTPC project.

Review of Asus Radeon HD 5850 1GB GDDR5 Graphics Card

INTRODUCTION

As usual when a new generation of graphics cards are is released, the first cards out on the market are the high end cards. In this case the HD 5870 and HD 5850. Later these have been followed by the 5770 and 5750 and we will soon see some lower end versions coming out too.

The release of the HD 5800 series brought a couple of new technology innovations with it. The "ATI Eyefinity" is a technology which enables one single card to support up to 6 monitors. "ATI Stream" enables GPU accelerated calculations, OpenCL gives us parallel GPU-CPU processing. However, the most important update is the support for DirectX 11 which in itself incorporates full support of Windows 7. This time around, Microsoft promises that the update of the DirectX API means a direct increase of the ratio between the graphical quality and the use of system resources.

AMD says their new GPU can achieve 2.7 TFLOPS, which really doesn't say much about what the GPU performs like in real world (gaming) situations, but it does tell us that it is truly a very powerful data processor. The manufacturing technology is now down to 40nm, which should mean less power consumption and heat development.

Talking about the power consumption, AMD now promises that the max consumption will not exceed 190W in full load and in idle mode the card will not surpass 27W. If this is correct it would be a big improvement compared to their previous generation of cards.

ASUS EAH5850 SPECIFICATIONS

OK, enough rambling about all the new technologies and promises of the new AMD series, here are the hard facts of the Asus HD 5850 card:

Asus hasn't added any physical alternations on this card; it is basically Asus' version of the generic AMD 5850. However Asus has a series of software tools which help us overclockers to reach the maximum potential of this card; the "Gamer OSD" and "Smart Doctor". This last application will be most useful since it allows us to play with the voltage of the core.

ASUS EAH5850, FIRST IMPRESSIONS

The card comes in a nice looking card board box with loads of aggressive printing on it. As is customary with graphics cards, ASUS pushes a lot on the overclocking tools. Also, the bundle (EAH5850/2DIS/1GD5) includes the game DIRT 2. When I opened the box, I almost got a little Apple feeling for a moment when I saw the black cover with the Asus logo in gold. Underneath the cover I found two boxes. The bigger box contained the graphics card itself, enfolded by a standard anti static plastic bag and protected by a white foam plastic material. The other box contained the accessories.

Except for the DIRT 2 game (digital download, no DVD), I wasn't overly impressed by the accessories; CDs with drivers and applications; a printed manual; a power adapter (2 molex to 1 x 6 pin PCIe), a DVI-VGA adapter and a CrossFireX bridge.

ASUS EAH5850 IN DETAIL

My first impression was that it really looks powerful with its red and black finish. The card faithfully follows the AMD reference card in all aspects. This is a big card, the length is 240 mm and it takes up two slots. The fan is a 70mm and I hope it will not bee too noisy, but looking at the rather small air exhaust in the back of card, I don't feel overly positive.

The front of the card holds two 6 pin PCIe connectors which would theoretically provide 150W to the card. Although I wanted to take the cooler off and have a closer look at the PCB I decided to let go of that intention since I would have to loosen a multitude of screws and it was impossible to remove only the housing without also clearing the cooler itself, which felt a little too risky. A great thing about AMDs new cards is their connectivity. They include two DVI-I, a HDMI and a DisplayPort. With the ATI Eyefinity technology, it is possible to use 3 monitors simultaneously with this card, not bad.

MY TEST SYSTEM

OK, so here comes the list of the hardware components I used for this test:

Test equipment

Crysis Warhead

Other software CPU-Z 1.52

GPU-Z 0.4.5

OCCT 3.1

And here's the screenshots of my configuration:

The main changes in my test setup are that I have included the benchmark software "Unigine Heaven" and removed Lightsmark 2008. The main reason for this is that it enables me to compare the difference in performance between DirectX 10 and DirectX 11.

BENCHMARKING RESULTS

I will not compare these results to the result I have received in previous graphics cards reviews since my test system has been updated. I was very interested in what the performance comparison between DirectX 10 and DirectX 11 would produce. As you can see from the graphs above the results were opposite of what I had expected, the performance was actually lower with DirectX 11 than with DirectX 10.

GAMING TESTS I

It is interesting to note that the performance remains high even when adding filters. This is something that AMD has corrected from their previous series which really suffered when filters were added. Otherwise, same here; the performance is very good but I will not make any direct comparisons to previous reviews.

GAMING TESTS II

The second batch of games includes more demanding games as usual. This test clearly shows that the EAH5850 has a lot of power under the hood and it was only in two games where the FPS rate didn't hold steady above 30 FPS with the highest possible settings.

OVERCLOCKING, REFRIGERATION AND CONSUMPTION

On the packaging, Asus emphasized the "Voltage Tweaking" which is done with the Asus Smart Doctor software which also lets us modify the frequencies of both the core and memories.

It's a dream to work with Asus' tool for overclocking the card and it is impressive just how far this card can be clocked.

The cooling system of the card is very effective. The fan is noisy at full power but mostly it didn't bother me too much.

I measured the total power consumption of my system in idle mode and in full load, here are the results:

Clearly the difference is enormous and it should be since AMD's PowerPlay technology has drastically diminished the power consumption in 2D.

OVERCLOCKING RESULTS

OK, so here are the results from the overclocking tests:

The increase in the 3D Mark Vantage was truly impressive and this is also confirmed by the increase of 6 FPS in Far Cry 2 and the increase is there with filters enabled as well.

CONCLUSIONS

I must first praise AMD for the work they have done with this card. It is both energy efficient and a high performer, very impressive. Asus has taken AMDs reference design and added a lot of value to it with their smart technologies and software tools. The main advantage with this Asus card is of course its overclocking abilities which are nothing short of fantastic. ASUS EAH5850 is already on sale at a price that oscillates between the $270 and $300, which is very competitive given its performance, overclocking abilities and the fact that it includes DIRT 2.
