Radeon 9600
That brings us to ATi's new mainstream product, the Radeon 9600, which will replace the 9500 series.
The Radeon 9600 VPU (alias RV350) is a fully DirectX 9 compliant chip and is based largely on the R300 core (more a mix between R300/R350), but with a few features omitted. Also, it is ATi's first chip to be produced on the same 0.13 micron process as the GeForceFX. As a result, it requires less current, can run at higher clock speeds, and produces less heat. The number of pixel pipelines has been reduced from eight to four, and the vertex shader units have also seen a cut, from four to only two. On paper, these cuts seem like a definite step backwards from both the Radeon 9500 and 9500 PRO. The RV350 does add the new "SmoothVision 2.1" and "SmartShader 2.0" enhancements, though, without "F-Buffer". The "Hyper-Z" optimizations, on the other hand, are still on the same level as that of the "old" R300, meaning 8:1 "Lossless Z" compression instead of the R350's 24:1 compression factor.

While we already have a review sample of the Radeon 9800 PRO, we won't be able to take a look at the 9600, since it won't be launched until later this month.
