AndroidAndMe has rewatched the Samsung Galaxy S keynote from earlier in the week (barrel of laughs 'round their way!) and realised that the 1GHz chip they mentioned - which can "process a staggering 90 million triangles per second" actually works out to three times faster than the Snapdragon processor.
Samsung's S5PC110 processor contains an ARM Cortex-A8 (codename of Hummingbird) and a PowerVR SGX540 GPU - which has only been seen in the Wave previously.
AndroidAndMe has compared the GPU to other available smartphones:
* Motorola Droid: TI OMAP3430 with PowerVR SGX530 = 7 million(?) triangles/sec
* Nexus One: Qualcomm QSD8×50 with Adreno 200 = 22 million triangles/sec
* iPhone 3G S: 600 MHz Cortex-A8 with PowerVR SGX535 = 28 million triangles/sec
* Samsung Galaxy S: S5PC110 with PowerVR SGX540 = 90 million triangles/sec
Looks very fast to me. [AndroidAndMe]
