Futuremark 3DMark06 build 1.0.2
ASUS EN7800GT Top Silent is only 98 points ahead of GeForce 7800 GT working at the nominal GPU and memory frequencies of 400MHz/500(1000MHz) respectively. But this time it manages to defeat Radeon X1800 XL having left it 248 points behind. It is a relatively significant performance difference for 3DMark06. However, before we make any final conclusions let’s take a look at the SM2.0 and SM3.0/HDR results individually.
The results of the graphics SM2.0 test affect the overall score quite significantly, because this test requires high fillrate speed. This definitely explains why ASUS EN7800GT Top Silent is so far ahead Radeon X1800 XL.
In SM3.0/HDR tests our hero wins another victory over Radeon X1800 XL despite the efficient Shader Model 3.0 implementation of the latter. It is the low GPU frequency of the Radeon X1800 XL that lets this happen. For your reference, the Radeon X1800 XT graphics solution with the GPU working at 625MHz shows the best result of all the testing participants here.
In the first SM2.0 graphics test ASUS EN7800GT Top Silent outperforms GeForce 7800 GT and Radeon X1800 XL only in 1024x768. In 1280x1024 all the graphics cards participating in our today’s test session show pretty similar results differing by 0.7fps at most.
The overall picture in the second SM2.0 test is very different from the first one. Namely, ASUS EN7800GT Top Silent, Radeon X1800 XL and the reference GeForce 7800 GT perform almost equally fast. Also, GeForce 7900 GT doesn’t stand out that greatly any more, because its high fillrate remains unused.
