Sony PlayStation Vita Specifications

The Hardware Specifications:

The Vita moves the bar forward in just about every single aspect for a gaming handheld: graphics, communications, and controls. The GPU and CPU are state of the art for the handheld and mobile industry; it will be the first handheld console ever to feature 3G cellular communications. Much to the delight of gamers, the Vita will also have two analog sticks in addition to a slew of secondary controls that include a multi-touch capacitive touch screen and a multi-touch rear touchpad. The Vita will also feature motion controls and GPS functionality. Games will ship on small flash memory-based cards, effectively pushing Sony's UMD format out of the picture. The Vita will be able to play PSP games from the PlayStation Store.

The basic hardware stats for the handheld remain unchanged since they were revealed back in January. Previously unannounced stats for the Vita pertain to the cameras, which didn't have any specific resolutions attached to them, and a full port list. Both cameras appear to be capable of recording video at 120 frames per second at a resolution of 320x240, and 60 frames per second at 640x480. The maximum resolution for both pictures and video appears to be 640x480.

Based on ARM's publicly provided Cortex A9 CPU specs, the chip can be configured in single, dual, and quad-core varieties. Based on its spec sheets, the dual-core variant comes in two flavors, optimized for either power or performance. The power-optimized chip lowers the clock speed to 800MHz, which results in 4,000 DMIPS (Dhrystone millions of instructions per second) of computational power and .5W of power consumption. The performance-optimized version bumps the speed up to 2GHz, and the computational power jumps to 10,000 DMIPS with 1.9W of power consumption. Assuming a linear scaling of performance, the ARM Cortex A9 with four cores could perform anywhere between 8,000 and 20,000 DMIPS. By comparison, the iPad, which is based off of the 1GHz Cortex A8, has roughly 2,000 DMIPS of computational power.
Imagination Technologies makes the PowerVR SGX543MP4+. However, we can only find information on the PowerVR SGX543MP. The normal nomenclature model for the PowerVR SGX543MP contains additional numbers following the MP that indicate the number of cores onboard. Imagine Technologies can configure the GPU to have 1, 2, 4, 8, and 16 cores. Sony opted to use the SGX543MP4+, which indicates that the chip has four cores. We have no details on what the "+" indicates.
Imagine Technologies states:
"At 200MHz core frequency an SGX543MP4 (four cores) will deliver 133 million polygons per second and fill rates in excess of 4Gpixels/sec. Higher frequencies or a larger number of cores each deliver more performance. At 400MHz core frequency an SGX543MP8 (eight cores) will deliver 532 million polygons per second and fill rates in excess of 16Gpixels/sec."
Assuming the chip hasn't been highly modified from the PowerVR SGX543MP4, a 200MHz PowerVR SGX543MP4+ could live up to the PlayStation 3's 4.4Gpixel/s fill rate spec. We also have to add that raw fill rate numbers rarely translate into real-world performance.
