this is forum reply that i made on other forum
but i am also posting it here
the powervr sgx540 (at 150 mhz ) is about the same as tegra 2 gpu core (at 240 mhz)
sgx543 is about roughly doubled sgx540
but the sgx543 is the first powervr gpu core that uses USSE2
* USSE2 - extended USSE instruction set with comprehensive vector operations and co-issue capability
* upgraded tile handling to further reduce memory bandwidth and improve performance for setup-bound applications
* typically 40% faster performance for 'shader-heavy' applications
* 2x floating point and 2x hidden surface removal performance
* enhanced triangle setup delivering up to 50% higher throughput
* improved multi-sampling anti-aliasing performance
* features for optimised performance when used with POWERVR VXD and VXE video cores
* advanced colour space handling and gamma correction
* further optimised OpenVG 1.x support
* cache and MMU improvements
