PlayStation 4 technical specifications

The PlayStation 4 technical specifications describe the various hardware components of the PlayStation 4 home video game console group. Multiple versions of this console have been released since the initial launch of the PlayStation 4, including the PlayStation 4 Slim and the PlayStation 4 Pro. Subsequent versions include changes to the technical specifications of the console.

The original released 420 GB HDD PS4s had manufacturer serial numbers of the form CUH-10XXA; a minor modification with a different form of Wi-Fi Microstrip antenna was registered in mid 2014 as part numbers CUH-11XXA.

In 2015, the CUH-12 series as variants CUH-1215A and CUH-1215B (with 500 GB and 1 TB storage respectively) were certified in the US by the FCC. Differences between the CUH-11 and CUH-12 series included a reduction in rated power from 250 W to 230 W, a reduction in weight from 2.8 to 2.5 kg, and physical buttons. The CUH-12xx series are also referred to as the "C chassis" variant of the PS4.

In late June 2015, a 1 TB CUH-11 series machine was announced for European/PAL markets.

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 but brighter 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).

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 500 GB 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 1 TB 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. Earlier PS4 models received HDR support with System Software 4.00.

The upgraded PS4 Pro (originally codenamed 'Neo', product code CUH-7000) used a more powerful APU built with a 16 nm FinFET process from TSMC. While the number of logical processor cores (8) was unchanged, its CPU clock speed increased from 1.6 GHz to 2.13 GHz (a 33.1% improvement in CPU core clock rate), but with the underlying architecture unchanged. The number of graphics Compute Units on the APU 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 2.2775× or 127.75% 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 was improved, with the addition of another 1 GB segment of DDR3 DRAM. The PS4 Pro could 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 512 MB of GDDR5 was available for developers to use for games adding up to 5.5 GB, as opposed to the 5 GB available on base PS4 hardware. GDDR5 memory speed was increased from 5.5 Gbit/s (or 4× 1.375 GHz) to 6.8 Gbit/s (or 4× 1.7 GHz), increasing total memory bandwidth to 217.6 GB/s which correlates to a 23.8% improvement.
