My friend has just bought a brand new Dell XPS 15 a GT420M (96 Tsuda H @ 500/1000/800). To overclock, I increased the level of a future release of GT540M (670/1340/900) holds the highest degree of temperature below 75 ° C (temperature so there is no question at all). In fact, the comparison was a lot of titles, I noticed that, in contrast to the GT335 (72 Cores Cuda – the Alienware m11x 450/1080/1066), retaining the resolution, the GT420 GT540 @ still performs about 20% slower than GT335 in the environment, and sometimes even the DX9 DX10 as well.
I know that the architecture of the other GPU, and GPGPU be more effective, by the way I thought, the overall results would be even better for the game (because of the rough on the GPU horsepower).
Now, the drivers are installed on the one provided directly by Dell (259.51), and until recently they were the only ones available to work (even optimus) on my card (I tried a modified *. inf from laptopvideo2go, but I ID_Hardware missing). I would like to know if anyone with similar configuration on the performance of the same questions, and if this is the “missing frames” can be one of the leading age-related problem, or if the architecture would really work in this way (only to improve the GPGPU IMHO, that useless for generic customers).
DX9 performance sometimes goes down even more and newer drivers. Not always, but I’ve seen that before long the DX 8.7. I havent read about it, but quite a few guys I’ve talked to has said the 400 series had a very bad mess.
As for CUDA and GPGPU performance I havent seen you post something to the class. DX10 physics tests will show a bit of the arena, there is a todo DX9 performance.
