Doc from ARM site says G51 MP3 has 4 execution engines and MP4 has 6.Then, does it means we can expect 6/4 times higher computing capability from MP4 than MP3? Not 4/3?
Arithmetic performance will scale by 6/4, but texturing performance and memory access performance scales by 4/3, so exactly what you see in terms of application performance will depend on the bottleneck you have in your shaders.
Note that Mali-G51 is really optimized for mass-market graphics content, so tends to favor a lower ratio of arithmetic-to-texturing than many of the other shader cores as this is the type of workload commonly found in UI, and light gaming applications. The Mali-G7x series has a higher ratio of arithmetic-to-texturing, and is tuned more for compute-dense applications.

Peter Harris Thank you, Peter.
