We’ve got an interesting bit of news regarding the PlayStation 4 CPU. The AMD-made processor will have a final clock speed of 2 GHz. So far the CPU has been underclocked at 1.6 GHz for development kits sent out to various developers.

Previous leaks put the clock speed at 1.6 GHz, but that was for development kits. The final clock speed for the 8-core AMD CPU will be bumped up 2 GHz according to our source. On top of that, the source reports that both the CPU and the GPU will be manufactured at 28nm at GlobalFoundries’ Fab 8 in New York — GlobalFoundries is co-owned by AMD. A desktop version of the “Jaguar” CPU will be available later this year.

The custom chip in the PlayStation 4 includes both the CPU and GPU — both components are made by AMD. The 8-core CPU is based on the upcoming “Jaguar” design, while the GPU is based on the Radeon 7000-series and is capable of 1.84 TFLOPS of processing power. That’s about 4.5x more powerful than the PS3 GPU.
