The ATI Radeon HD 3650 is the slowest card again. You can note that MSI’s pre-overclocking of the GPU has almost no effect on the final result here.
The Radeon HD 3650 behaves in the same way in both SM2.0 and SM3.0/HDR tests. In the latter group of tests it is about as fast as the Nvidia GeForce 8600 GTS which feels a lack of computing capacity. The effect from factory overclocking is negligible in both cases.
The gap between the Radeon HD 3650 and the GeForce 8600 GTS is smaller in the second SM2.0 than in the first one because the performance of the texture processors is not a decisive factor then.
Here, it is the second SM3.0/HDR test that shows a considerable advantage of the Nvidia GeForce 8600 GTS over the ATI Radeon HD 3650 although it doesn’t load the TMUs as much as the first SM3.0 test does and mainly displays HDR effects and dynamic CSM shadows. The Radeon HD architecture should cope with such shadows better thanks to Gather4/Fetch4 features but it is not so, perhaps due to the less efficient TMU architecture overall. Anyway, these results agree well with the overall 3DMark06 scores.
