What we’ve done today is compare the Diamond HD 3650 against the Sapphire HD 3650. Diamond does something that is quite common when companies increase the amount of RAM on lower end models. Instead of using 1GB of GDDR3, they’ve dropped back to GDDR2. With the Sapphire card however, while only having 512MB of memory, it is GDDR3 based.
3DMark06 is the very latest version of the “Gamers Benchmark” from FutureMark. The newest version of 3DMark expands on the tests in 3DMark05 by adding graphical effects using Shader Model 3.0 and HDR (High Dynamic Range lighting) which will push even the best DX9 graphics cards to the extremes.
3DMark06 also focuses on not just the GPU but the CPU using the AGEIA PhysX software physics library to effectively test single and Dual Core processors.
We can see straight away that the increased speed on offer from the Sapphire 256MB model gives it the better performance.
