The Snapdragon S4 Prime MPQ8064 chipset powers an up to 1.7 Ghz Qualcomm Krait quad core processor and is very similar in spec to the Snapdragon S4 Pro APQ8064 which is also listed on this website. The chipset has been used by very few unlike the APQ8064 chipset.
The basics of the chipset is as follows:
The level 2 cache on the processor is twice as large as the norm being 2,048 KB/Core which is normally reserved for high-end mobile phones where multimedia options are used. It comes with a good GPU in the form of the Qualcomm Adreno 320. It allows the chipset to run video in 1080p and can power a screen resolution of 2048 x 1536 pixels. That is large for a mobile phone. With the multicore the chipset is very efficient at multitasking and comes in well with phones which have a large memory and good quality cameras. This chipset will manage up to 20 MP cameras.
