Which VXD does the iPhone 5s have?
Their newer ones support HEVC/H.265 decoding!

I'm not sure about the working clocks of these VXD video accelerators and if all of them are integrated inside PowerVR SGX GPU and I don't know If they have the same clock as the GPU but in any case, every iPhone from 3GS to 5 uses a different VXD accelerator.
iPhone 3GS = PowerVR SGX535@150 MHz + VXD370
iPhone 4 = PowerVR SGX535@200 MHz + VXD375
iPhone 4S = PowerVR SGX543MP2@200 MHz + VXD385 (most probable)
iPhone 5 = PowerVR SGX543MP3@266 MHz + VXD390
So because of possible different clocks of various VXD processors inside iPhones and because of definitely different VXD architectures, we could say for sure that hardware acceleration performance of iPhones is not the same across the line.
