<P> The CUH - 1200 series was officially announced in June 2015, releasing first in Japan, then worldwide . Changes to the design included a matte black HDD cover replacing the original gloss black version . Other minor changes to the design included mechanical buttons replacing electrostatic touch sensitive ones, and a shorter LED indicator on the top surface of the console . Internally the CUH - 12 series included a number of minor changes, including the change to 8 memory modules of 1 GB (from a previous 16 modules of 512 MB). </P> <P> At a PlayStation official event in New York (USA) in September 2016 Sony officially announced a new redesigned PS4, the CUH - 2000 series, (known colloquially as the "PS4 slim") for sale from 15 Sep at $299, € 299, £ 259, or 29,980 Yen for the base 500GB model . According to a Sony press release the new model (CUH - 2000) was 16% lighter and used 28% less energy than the CUH - 1200 series . A 1TB model at 34,980 Yen was also announced . At the same event a more powerful variant, named the "PS4 Pro" was also announced, designed for 4K and HDR displays . </P> <P> The upgraded' PS4 Pro' (originally codenamed' Neo', product code CUH - 7000) uses a more powerful APU initially built with a 16 nm FinFET process from TSMC . While the number of logical processor cores (8) remained the same, CPU 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 GPU, this is a 2.27 X 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 . </P> <P> 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 5.5 GB, as opposed to the 5GB available on base PS4 hardware . GDDR5 memory speed was increased from 5.5 Gbit / s (or 4x 1.375 GHz) to 6.8 Gbit / s (or 4x 1.7 GHz) increasing total memory bandwidth to 217.6 GB / s which correlates to a 23.8% improvement . </P>
