1st off MT Arm processors are not one of the best performance Processors out there, so they in fact rarely get to those listed Gflops/sec let alone sustain them. also as for the PSVita maxing out @ 52 Gflops , You may want to do some more research SGX 543 MP4 = 38.4 GFLOPS (triple core tho) http://www.anandtech.com/show/6426/ipad-4-gpu-performance-analyzed-powervr-sgx-554mp4-under-the-hood A) the Speed of the SGX543MP4+ is more than 400 MHz B) C) since its a 3D stacked TSV its performance index is very..very High That Smatphone you gave as an example i doubt very much is not going to outpace the PSVita's Performance index again: another example is the clock rate can indeed be pushing over 533 MHz, since sony has a SGX543MP4"+" being and increase clock rate, among other things you can take also as an index: The Exynos variant of the Samsung Galaxy S4 sports the tri-core SGX544MP3 clocked at 533 MHz. The series x5 Power VR GPU's were and still are some of the best GPU's that give a High Performance on Mobile SOC's..still even Today. Yes there is more powerful mobile chipsets than the PSVita, but many time the Costs are still High, and Again you would d@mn sight need to be on a contract for a mobile carrier to get it for 2 year contract, and thats still way more than $70.00 |
You realise that some MT chips, like the MT5327, have the SG543 MP2. So that kind of contradicts your statement about MT chipsets. But here is an article about this chip in particular anyway.

This is a very fast processor. It has 8 cores clocked at 600 Mhz each, and it topped AnTuTu for a period of time. Its GPU is a PowerVR G6200, which competes with the Adreno 330.

The only reason the phone I linked is so cheap is because it doesn't take advantage of the processor's abilities with certain features. Its resolution is only the same as the Vita's while this processor is designed for QHD resolutions, for example. Still, the core hardware without any fancy features to best/match the Vita's processor is less than $100 and can get as low as $70.
As for the Vita's performance.

PowerVR SGX 543MP4 - 38.4 GFLOPS
That's on the IPAD 3, the 52 GFLOP estimate considers the factors you mentioned, like Sony overclocking.
The VIta has an SGX 543MP4, by the way, not an SGX 544MP4.
