There is an interesting video over on IGN (sadly I cannot embed into my blog) that says the PS4 has been in development at Sony for the past couple of years, which goes against many rumours saying they have only just started develpment.
The uncovered tidbits revolve around an ex-Sony employee named Atilla Vass, whose CV (curriculum vitae) on LinkedIn talks a bit about the “Next Generation PlayStation”. Vass worked at Sony for 14 years, beginning in May of 1998. His tenure at Sony, according to his CV, ended in April of 2012. His specialty appeared to have been “R&D” centering on technology ranging from graphics to cloud services and more.
Specifically, he talks about how, from August 2010 until April of 2012, he worked simultaneously on PlayStation Vita and what he calls the Next Generation PlayStation. For the latter, he worked on Graphics Library and Security. He founded some 17 technology patents for Sony, suggesting that his work on Sony’s platform may have very well been of the integral variety.
The HD 7670 is a rebranded version of last year’s HD 6670, sporting identical specs across the board. If you recall, the HD 6670 is the same card that we reported will be used in the Xbox 720. The implication, of course, is that the two systems will effectively go toe-to-toe as far as discrete graphics are concerned.
By current standards, the HD 6670 is an entry-level processor with a price of about $74.99. Benchmark tests place framerate performance for taxing titles games like Metro 2033 and Crysis 2 set to high settings at a resolution of 1920×1080 (1080p) with average framerates of just over 30 frames-per-second. The chip also supports HDMI1.4a output, which is necessary for the system’s rumored 4k output. Naturally, a comparably lightweight operating system and console-optimized games will likely improve performance, but the PS4’s real edge could come from the secondary GPU provided by the APU.
Onboard the A8-3850 is an HD 6550D, which makes the APU capable of running games at baseline specs and lower resolutions without the help of a discrete GPU. When the APU is paired with the HD 7670, however, Sony will be able to utilize an asymmetrical CrossFire configuration to share the load of realtime graphics processing.
Our sources caution that while current plans for the device make use of the the chipsets mentioned, it is possible that changes could be made prior to the system’s launch.
