X4500 is Slower than GMA 3100

1,291 Views

Hi,

I have intel core2duo (DG41RQ) mother board with integerated graphic chipset.( GMA X4500).

I have another pc DG33FB mother board with integerated graphic chipset.( GMA 3100) which is a previous generation than X4500.

I use "PerformanceTest" software to test 3d performance on both PC.

The same test runs faster on 3100 and slower (about half speed) on x4500.

Performance of 2d test are a little bit faster on x4500.

Can any body explain what is the reason for that.

I have tried with griphic dirver 14.42.4.5258 and 6.14.10.5284. The perfomance is same with both drivers.

I have also tired more latest drivers 14.42.4.5268and 14.42.4.5273 but any 3D application or game that use vertex shader hangs the system with these drivers.

Regards

Arban.
