We had always reported that Qualcomm’s Snapdragon GPU was slower than the PowerVR SGX used in Apple’s A4 and TI’s OMAP 3, but we didn’t have a good idea of how much slower. When Brian first started cranking on the Droid X review he wanted to put the Qualcomm Adreno 200 vs. The GPU Performance Showdown: Snapdragon vs. Should a customer choose to go for 200MHz LPDDR1 you’d get a 20% increase in memory bandwidth which will come in handy with the faster GPU in 3D apps for sure. The memory controller is still a 32-bit LPDDR1 interface, but can now run at up to 200MHz (the 3430 was limited to 166MHz). Just as with the CPU, there are no significant architectural changes to the GPU - it just runs faster. The 80% increase in GPU clock speed should result in significant real world GPU performance improvements. Intel runs the SGX 535 in Moorestown (Atom Z600 series) at 200MHz as well and I believe that’s what Apple uses in the A4 as well. We’re seeing a lot of convergence around this 200MHz mark at 45nm. While the OMAP 3430 ran the GPU core at ~110MHz, the 3630 ramps it up to 200MHz.

Until we get a Moorestown dev kit running Android we won’t be able to shed much light on that. We’d expect that 3D apps on smartphones are more compute bound these days so it’s difficult to say how much you lose by going with the SGX 530 vs. The SGX 535 used in Apple’s A4 and Intel’s Atom Z600 series apparently have a second texturing unit and DirectX 9L support. Both the SGX 530 and 535 have two USSE pipes from what I can tell. Each USSE pipe can execute a 2-wide vector or up to a 4-way SIMD scalar op in a single clock. ImgTec refers to the execution hardware in its Series 5 GPUs as a Universal Scalable Shader Engine (USSE).

The difference between the SGX 530 and 535 is as follows. Rather than move to the PowerVR SGX 535 used by Apple and Intel, TI stuck with the same PowerVR SGX 530 core used in the OMAP 3430.
