[Geek3D-Test] FurMark, Catalyst 8.8 and HIS Radeon HD 4850: Torture Test PASSED!

Ok now that I have in my hands a HIS’s Radeon HD 4850, I played with this card and of course did the FurMark renaming experience with Catalyst 8.8 (see ATI Optimizes Catalyst 8.8 to be FurMark-Proof!). The difference of score in simply… incredible, better it’s shocking! Here is the score when I launch FurMark.exe: 2234 points


And now, the score when FurMark.exe is renamed in… ati.exe (why not?): 4383 points


This score is almost twice the first one. That explains now the odd result I get with FurMark in this post: ATI Catalyst 8.8 vs 8.7: OpenGL Performance Drop.

I launched in the same time the Catalyst Control Center in the Overdrive panel to check how frequencies vary:


In both tests, the frequencies were the same. ATI Catalyst 8.8 does not downclock the GPU frequency but makes the GPU running slower (what does it means???). Anyway, it seems obvious the Radeon HD 4800 series have some serious thermic problems. Maybe I could add a kind of GPU temperature limitation for Radeon HD 4800 series. If temperature exceeds 90 degrees on Radeon HD 4850 and HD 4870, FurMark will stop the rendering or will render one frame over two or three… But actually I think I’m not going to do that. FurMark is a torture test but it’s most of all a standard OpenGL application. I don’t use low level code or different rendering path for Radeon or GeForce. The same code is injected in both rendering pipeline. And then any OpenGL 2.0 compliant GPU should process this code if the surrounding graphics hardware (I mean memory modules, power MOSFETs properly cooled, etc.) is well designed and implemented by graphics cards makers. The proof, HIS’s Radeon HD 4850 PASSED all FurMark tests I did, with stock clocks as well as with overclocked clocks.

Now dear readers, let’s burn HIS’s Radeon HD 4850.

– Stock clocks: GPU=625MHz and Memory=993MHz

  • 94 degrees after 3 minutes in 640×480 no AA windowed mode: TEST PASSED!
  • 96 degrees after 3 minutes in 1024×768 no AA windowed mode: TEST PASSED!

– Basic Overclocking: GPU=660MHz and Memory=1005MHz

  • 96 degrees after 3 minutes in 1024×768 no AA windowed mode: TEST PASSED!

– Overclocking: GPU=680MHz and Memory=993MHz

  • 96 degrees after 3 minutes in 1024×768 no AA windowed mode: : TEST PASSED!

– Overclocking: GPU=680MHz and Memory=1100MHz

  • 97 degrees in 1024×768 no AA windowed mode. After 140 seconds, VPU Recover:

Yes the latest overclocking was a little bit extreme, but it shows HIS’s Radeon HD 4850 is a very good product and is already FurMark-Proof. No need hidden tweak in Catalyst to run FurMark. I think graphics cards that do not resist to FurMark torture tests are either bad quality products or have some bad cooled parts like the VRM (voltage regulator modules)…

ATI Optimizes Catalyst 8.8 to be FurMark-Proof!

15 comments - What do you think?  Posted by JeGX - 2008/08/26 at 10:32

Categories: Catalyst, FurMark, Graphics Cards   Tags: , , , , , , ,


Here is an incredible news to start the day: Expreview has found that ATI’s Catalyst 8.8 have been optimized to detect FurMark and downclock the frequencies of a Radeon HD 4850/4870 to avoid to burn the GPU.

So if you have a Radeon HD 4850 or Radeon HD 4870, just rename FurMark.exe in something.exe and you will see the difference!

Expreview has done the test with Quake Wars: Emeny Territory and has renamed etqw.exe to FurMark.exe and saw performance drop from 141.3FPS to 93.7FPS!

I have not a Radeon HD 4000 series but I think that I’m going to buy a Radeon HD 4850 today!

It’s a pain to develop a benchmark to make it running properly on most graphics hardwares and now I have to include in FurMark a Catalyst anit-cheat???? Thanks AMD/ATI….

Why AMD doesn’t contact me directly to find out the problem???

[Geeks3D-Test] ATI Catalyst 8.8 vs 8.7: OpenGL Performance Drop

2 comments - What do you think?  Posted by JeGX - 2008/08/24 at 23:51

Catalyst 8.8 graphics drivers have been released few days ago, and today, or better this evening I’ve done some tests with oZone3D.Net OpenGL Benchmarks and a Radeon HD 3870 (stock clocks). I also used Lightsmark 2008 in order to have another OpenGL 2.0 application to confirm oZone3D.Net OpenGL benchmarks.


Here are the results, rather unexpected

Catalyst 8.7 Catalyst 8.8 Diff
FurMark 1280×1024 3100 3229 +4%
FluidMark 1280×1024 954 937 -1.8%
Soft Shadows Branching OFF 3384 2590 -23%
Soft Shadows Branching ON 4088 2993 -26%
Surface Deformer 13526 10332 -23%
Lightsmark 2008 391 376 -4%
TOTAL Sum 25443 20457 -18%


System Configuration: Core 2 Duo E8400 default clock, motherboard EVGA 790i Ultra SLI, 2Gb DDR3 1333, HIS Radeon HD 3870 default clocks, Catalyst 8.8 XP32, Windows XP SP2 32-bit.

Global Performance Drop: 18%. OpenGL performance tumbled by around 26% in dynamic branching (soft shadows), around 23% in vertex processing (surface deformer) and around 4% in Lightsmark 2008. Only FurMark takes advantage of Catalyst 8.8 with a little 4% of performance boost. FurMark makes an intensive use of texture fetching and blending (ROPs) and maybe ATI has improved something in this part of Catalyst. But as said hereafter, Expreview has noticed a performance drop with a Radeon HD 4850 and FurMark. I don’t have such a radeon and then I can’t confirm this last result but FurMark score is somewhat weird…

Expreview on his side, has tested the Catalyst 8.8 with an ATI Radeon HD 4850 and compared to Catalyst 8.7, the new driver boosts the performance in games. If you have a Radeon HD 4850, Expreview recommends you update to Catalyst 8.8. But if you look at the results more seriously, you can notice that scores are boosted mainly for DirectX 10 titles. In other OpenGL or DirectX 9 titles, there is no or a little boost only. And with FurMark, Expreview has the same kind of performance drop I had with the HD 3870.

TweakTown in his Catalyst 8.8 review has also experienced a severe OpenGL performance drop with Radeon HD 3870 and Cinebench, the OpenGL benchmark derived from Cinema 4D. The Radeon HD 4870 has a drop too but less important.

Conclusion: for OpenGL applications that are performance focused, it’s better to not use Catalyst 8.8. In some cases, Catalyst 8.8 brings a little boost only and in other cases, a dramatic drop is noticed.

If you have some interesting results with OpenGL applications, do no hesitate to post a comment!

Sapphire Toxic Radeon HD 4850 Review

Be the first to comment - What do you think?  Posted by JeGX - 2008/08/07 at 09:33

Categories: Graphics Cards, VGA Coolers   Tags: , , , , , , , ,

The biggest problem of Radeon HD 4850 is that this card reaches high temperatures (70 degrees celcius) even in idle (i.e. not loaded). So manufacturers decided to discard the stock cooler in favour of a better and more efficient cooler. In these reviews, the Sapphire’s solution, the Radeon HD 4850 Toxic edition, is analyzed. This Radeon features a Zalman heatpipe fan, providing more efficient cooling, quieter operation and more headroom for performance tuning.


Due to the better cooling solution, frequencies have been overclocked:

Toxic Radeon HD 4850 has the following features:
– GPU: RV770
– stream processors: 800
– ROPs: 16
– transistors: 956M
– memory 512Mb / 256-bit
– core clock: 675MHz
– memory clock: 1100Mhz
– DirectX 10 / OpenGL 2.1


However, the Sapphire cooling solution is one of the noisiest cards under idle: around 40db. But this cooler does its job by keeping GPU temperature at least 20 degrees lower than a standard Radeon HD 4850.

MSI Radeon HD 4850 Review

Be the first to comment - What do you think?  Posted by JeGX - 2008/08/05 at 09:27

Categories: Graphics Cards   Tags: , , , , , ,

FiringSquad has reviewed the MSI’s Radeon HD 4850 that runs significantly cooler than ATI’s stock Radeon 4850 reference design. To reach that goal and offer maximum cooling performance, MSI uses four copper heatpipes for cooling the RV770 GPU. With their copper design, the heatpipes are capable pulling quite a bit of heat off the GPU. This heat must then be dispersed in order to prevent the heatpipes themselves from becoming a hotspot on the graphics card. To accomplish this, MSI employs a dual-slot aluminum heatsink.

Main features of the Radeon HD 4850:
– GPU: RV770
– 800 stream processors
– ROPs: 16
– Transistors: 956 million
– Memory: 512Mb GDDR3 256-bit
– core clock: 625MHz
– memory clock: 1.0GHz
– DirectX 10 / Shader Model 4.1
– OpenGL 2.1

The weird thing is FiringSqaud has used the Catalyst 7.7 to test this Radeon. Mistake???

TT-Hardware nous propose un article comparatif des performances entre la GeForce GTX 280 et les Radeon HD 4870/4850.

Lire le test complete ICI.

La GeForce GTX 280 confirme qu’elle est bien la carte de tous les superlatifs : la plus grosse, la plus complexe, la plus performante mais aussi la plus encombrante, la plus bruyante, la plus gourmande et surtout la plus chère (de 460 € à plus de 500 €). Des points faibles qui pèsent lourd par rapport aux avantages surtout que la Radeon HD 4870 vient jouer les trouble-fêtes. En effet, si la Radeon HD 4870 est un peu en retrait par rapport à sa rivale, elle est surtout beaucoup moins chère (230 €) et nettement plus discrète. Sa seule contrepartie est une consommation importante au repos. La Radeon HD 4850 (moins de 160 €) est la révélation de ce comparatif : elle ne souffre d’aucun point faible. Ses prestations la mettent en concurrence avec la GeForce 8800 GTS OC MSI ainsi que les GeForce 9800 GTX et GTX+ (220 à 230 €). Ces dernières sont au moins 30% plus chères et nettement plus bruyantes et donc dans l’état actuel des choses sans le moindre intérêt ! Seules les GeForce 8800 GTS 512 Mo peuvent encore tirer leur épingle du jeu en raison d’un prix inférieur à 200 € et un silence de fonctionnement plus qu’appréciable. Particulièrement intéressante à son lancement, la GeForce 9600 GT est aujourd’hui caduque.

Categories: Graphics Cards   Tags: , , , , ,

Sapphire has always offered the most influential ATI graphics products available, and the new Radeon HD 4850 is no different. Although it still uses GDDR3 clocked at 993 (1986 MHz DDR), unlike the 4870 version that is decked out with GDDR5, the Sapphire 100242L model offers 24x custom filter anti-aliasing (CFAA) on its 625 MHz 800-core RV770 GPU. Benchmark Reviews tests the Sapphire Radeon HD 4850 graphics card against the closest competition, and even compare CrossFireX performance in this performance review.

Since Radeon series 4800 cards offer so much value, it might even be interesting to pair them in CrossfireX mode. AMDs ATI solution can be paired and matched as well. So today Guru3D has placed several cards together in CrossfireX mode.

Read the complete review HERE

No kidding it is sick how much performance these cards combined can push, the 2-way GPU scaling is just really superb. Crossfire with two series 4800 cards definitely makes more sense than NVIDIA’s high-end SLI money wise.
