PlayStation 4 technical specifications

[-INTOX-]

The PlayStation 4 technical specifications describe the various components of the PlayStation 4 (PS4) video game console.

The original released 500GB HDD PS4s had manufacture serial numbers of the form CUH-10XXA; a minor modification with a different form of WiFi Microstrip antenna was registered in mid 2014 as part numbers CUH-11XXA.[1][2]

In 2015, the CUH-12 series as variants CUH-1215A and CUH-1215B (with 500GB and 1TB storage respectively) were certified in the USA by the FCC. Differences between the CUH-11 and CUH-12 series included a reduction in rated power from 250W to 230W, a reduction in weight from 2.8 to 2.5 kg, and physical buttons.[3][4][5] The CUH-12xx series are also referred to as the "C chassis" variant of the PS4.[6]

In late June 2015, a 1TB CUH-11 series machine was announced for European/PAL markets.[7]

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.[8][9][10] 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.[11][12] 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).[13]

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.[14][15] According to a Sony press release the new model (CUH-2000) was 16% lighter and used 28% less energy than the CUH-1200 series.[14] A 1TB model at 34,980 Yen was also announced.[14] At the same event a more powerful variant, named the "PS4 Pro" was also announced, designed for 4K and HDR displays.

PlayStation 4 Pro[edit]

The upgraded 'PS4 Pro' (originally codenamed 'Neo',[17][18] 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 2.27X 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 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 217.6GB/s which correlates to a 23.8% improvement.

Some elements added to the design were derived from AMD's newer Polaris and newer architectures;[20][21] such new features of the processor included a HEVC video codec supporting up to 4k resolution. Other specification changes included HDMI output to HDMI 2.0b standard, with HDCP 2.2 compliance. Wireless networking included 5 GHz band support using the IEEE 802.11ac standard, and Bluetooth support was to version 4.0; wired LAN was as the original PS4. The rated power of the original PS4 Pro was 310W.

The PS4 Pro does not support Ultra HD Blu-ray (UHD BD) discs, used for 4K content, as the BD-ROM internal drive does not support the BDXL format (100GB +) required for 4K video, on preliminary tests the console is able to recognize and play these discs on a 4K capable USB 3.0 external disc drive.[citation needed] The decision not to upgrade was predicated primarily on cost.

A limited translucent case-version of the PS4 Pro was released in August 2018, which include minor hardware updates. This new system, model number CUH-7100, besides offering a larger hard drive, used a quieter fan that helped to reduce the noise levels. It also drew power at a consistent rate compared to the CUH-7000, though ran slightly hotter than the launch system.

A second minor hardware refresh, with model number CUH-7200, was first released in bundles with Red Dead Redemption 2 in November 2018. The newer version, otherwise functionally equivalent to the CUH-7000, has a different power connectors, and uses a quieter fan, which, according to Digital Foundary, made a "night and day" difference in the noise level, similar to the improvements in the CUH-7100. It further draws power consistently at 170W, whereas the 7000 while rated at 170W would have brief spikes up to 177W. However, the newer console runs slightly slower and hotter than the 7000 model to gain this improvement.
