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!

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

Phoronix has tested VisionTek’s Radeon HD 4870 X2 2GB under Ubuntu 8.04.1 32-bit with the Linux 2.6.24 kernel and the latest ATI Catalyst 8.8. Catalyst 8.8 for Linux supports CrossFire, OverDrive overclocking, adaptive anti-aliasing, and other improvements. The benchmark suite used by Phoronix includes OpenGL titles like Doom 3, Quake 4, Enemy Territory: Quake Wars and the Phoronix Test Suite.

The conclusion of this test is the Radeon HD 4870 X2 isn’t quite as far as two Radeon HD 4870 512MB graphics cards linked together via CrossFire, but it’s darn close.

ATI Radeon HD 4870 Overclocking Guide

TechARP has published an article about Radeon HD 4870 overclocking. They used ATI Catalyst Control Center (or CCC) to overclock the card. The overclocking principle is to firstly to overclock the graphics memory with steps of 10Mhz until you see some visual artifacts. Once you see artifacts, downclock by around 10/20MHz. Second phase, overclock the GPU. Reset memory clock to default and increase GPU clock with steps of 10MHz and do the same artifact test than for memory.

PowerColor Radeon HD 4870 Fails to Complete FurMark

Be the first to comment - What do you think?  Posted by JeGX - 2008/08/14 at 13:55

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

Expreview has done some tests on the new Powercolor product, the Radeon HD 4870:


One of these tests is FurMark and the HD 4870 fails to complete one minute of FurMark’s stability test. Failure symptoms are VPU recovery message, red LED (on the PCB) that shines…

For one thing, BIOS limited fan speed too low, that results in a higher GPU temperature; For the other thing, it gets through 3DMark Vantage, but fails to complete FurMark test. We believe it’s the BIOS setting that causes these problems and asked PowerColor for a new BIOS, but the answer was not available yet.

Other pictures of Powercolor’s Radeon HD 4870: PowerColor HD 4870 in our hand, looks even better than reference.

Categories: Graphics Cards   Tags: ,

Sapphire’s Radeon HD 4870 reviewed at Hardware Secrets.

Read the full review HERE.

In most scenarios Sapphire HD 4870 was between 20% and 30% faster than Sapphire HD 4850, but on some games like Quake 4 and Half-Life 2: Episode Two both cards achieved a similar performance, depending on the video configuration used.

Sapphire HD 4870 and GeForce GTX 260 achieved a similar performance in most scenarios. The only time that GeForce GTX 260 was faster than Sapphire HD 4870 was on Call of Duty 4 at 2560×1600 maxing out image quality settings (11% faster). In all other configurations on this game both cards achieved the same performance level.

InfraRed Photo Shows which Part of Your HD 4870 is Hot While Running FurMark

5 comments - What do you think?  Posted by JeGX - 2008/07/18 at 17:23

Categories: Benchmarks   Tags: , , , , ,

German Radeon user Tiesie have posted some Infra-red photo of his/her HD 4870 with Arctic Cooling Accelero S1. The sticker part is hot and keeping the reference red cooler base is no help for cooling. All these shots have been taken after 10~20min of FurMark.

I wonder if Tiesie has used FurMark in Xtreme Burning mode (currently command line but soon in the startup dialog box) or in standard mode…

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.

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.
