Hey everyone, i read quite a lot about hardware and i found this interesting article on the french website (Hardware.fr). I translated it for you guys because i think it's interesting.
Check this out and sorry for the mistakes, my primary language is french. Post your comments and make this thread stay!
" As you already know if you read our articles on a regular basis, Quad Core CPUs are not yet well used in actual games. If in fact the use of Dual Core CPUs is more spread out, not many games can use full benefit from additional cores.
With some tests to observe the dependence of Quad Cores, we arrived to the conclusion that one parameter has more impact than expected : the graphic card, or rather, it’s driver. In our protocol test the CPUs, we use to games, Crysis V1.2 (using it’s integrated benchmark_cpu2) and World in Conflict V1.0.0.9 (also using the integrated benchmark). In both cases, the tests are done using 800*600 to limit the impact on the graphic card and concentrate on the limitations of the CPUs. Details are set to the Maximum so the level of stress on the CPUs is as high as possible.
Here are the results we obtained with an E8400 and an Q9650, both clocked at 3 GHZ. We put in both a Radeon 4870 (Catalyst 8.11 hotfix) and a GTX 280 (Forceware 180.48). DX9 and DX10 under vista 32bits :
The results speaks for themselves! With DX10 and an Nvidia card, the gain is about 21 to 24% when you pass from 2 cores to 4 cores. With the ATI card, the gain is minimal. On the other hand, with DX9, the gains are less important : only 10 to 11% gain with Nvidia, and this time, but only with Crysis, we note an almost similar amelioration with the Radeon. We have to say that in DX9 and DX10 mode under Vista, the multi-threading is not managed the same way.
The obtained results clearly show that the DX10 Nvidia drivers are better suited for multi-thread than the DX10 AMD ones, which are almost not or not multi-thread friendly. We can see that the Nvidia card is more suited to substantial gain from a Quad Core CPU, which can’t be taken lightly when you are in a game in which the CPU can limit the performance ( Note: sorry for the last sentence, my English is not A1..)
From Intel’s saying, 25 to 40% of the CPU load in a game is linked to Direct3d and to the graphic card driver. The threading from this load is not negligent, and it would be more than useful that AMD get is nose in this issue to rapidly give at least something comparable to Nvidia in their drivers."
That's it.
