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
I launched in the same time the Catalyst Control Center in the Overdrive panel to check how frequencies vary:
Now dear readers, let’s burn HIS’s Radeon HD 4850.
– Stock clocks: GPU=625MHz and Memory=993MHz
– Basic Overclocking: GPU=660MHz and Memory=1005MHz
– Overclocking: GPU=680MHz and Memory=993MHz
– Overclocking: GPU=680MHz and Memory=1100MHz
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)…
|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???
Expreview has done some tests on the new Powercolor product, the Radeon HD 4870:
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.
