PlayStation 4 Pro Specs
The upgraded 'PS4 Pro' (originally code named Neo) product code CUH-7000 uses a more powerful APU initially built with a 16nm FinFET process from TSMC. While the number of logical processor cores (8) remained the same, clock speed was increased from 1.6 GHz to 2.13 GHz (33.1% improvement in CPU core clockrate), but with the underlying architecture unchanged. The number of graphics compute units on the APU was doubled to 36 Graphics core next (GCN) compute units (from 18), with a clock speed increase to 911 MHz(from 800 MHz), resulting in a theoretical single precision floating point performance metric of 4.19 Teraflops compared to the original PS4 CPU, this is a 2.27X increase in single precision FLOPS. Improvements in GPU 16 bit variable float calculations derived from the newer AMD Vega architecture result in the PS4 Pro having a theoretical half precision floating point performance of 8.39 TeraFLOPS. Overall unified system memory architecture has been improved, with the addition of another 1GB segment of DDR3 DRAM. The PS4 Pro is able to use this increase in memory to swap out non-gaming applications that run in the background, like Netflix and Spotify. As a side benefit to this, an additional 512MB of GDDR5 is available for developers to use for games adding up to 5.5GB, as apposed to the 5GB available on base PS4 hardware. GDDR5 memory speed was increased from 5.5Gbit/s (or 4x1.375 GHz) to 6.8Gbit/s (or 4x1.7 GHz) increasing total memory bandwidth to 217.6GB/s which correlates to a 23.8% improvement.
