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. 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. The CUH-12xx series are also referred to as the 'C chassis' variant of the PS4. In late June 2015, a 1TB CUH-11 series machine was announced for European/ 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, 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). 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 and displays. PlayStation 4 Pro [ ] 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.

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 (GCN) Compute Units (from 18), with a clock speed increase to 911 MHz (from 800 MHz), resulting in a theoretical performance metric of 4.19 TeraFLOPs. Compared to the original PS4 GPU, this is a 2. Ielts Foundation Macmillan Teacher. 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; such new features of the processor included a video codec supporting up to 4k resolution.

Other specification changes included HDMI output to HDMI 2.0b standard, with 2.2 compliance. Wireless networking included 5 GHz band support using the standard, and 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 (UHD BD) discs, used for 4K content, as the internal drive does not support the format (100GB +) required for 4K video, on preliminary tests the console is able to recognize and play these discs on a 4K capable USB3.0 external disc drive.

'[We] have not built an APU quite like that for anyone else in the market. It is by far the most powerful APU we have built to date'. — John Taylor, AMD The PlayStation 4 uses a semi-custom (APU) developed by in cooperation with Sony and is manufactured by on a process node.

Its APU is a single-chip that combines a (CPU) and (GPU), as well as other components such as a and /. The console also includes secondary custom chips that handle tasks associated with downloading, uploading, and social gameplay. These tasks can be handled seamlessly in the background during gameplay or while the system is in. Though not much is publicly known of the PS4's audio capabilities, the console also contains a dedicated hardware audio module, which can support in-game chat with minimal external resources as well as 'a very large number' of streams for use in in-game audio. APU [ ] The main APU (2013 release) had a die size of 19 by 18.3 mm (0.75 by 0.72 in), with GPUs, CPUs and memory controllers on the same die. 2013 release version APUs contained 20 compute units on die, two of which are thought to be present to provide redundancy to improve manufacturing yield.

CPUs plus CPU caches make up approximately 15% of the chip area, and the GPU compute units take up approximately 33% of the 348 mm 2 (0.539 sq in) die area.

How To Determine Your PS2 Playstation 2 Version Follow this guide to determine your PS2 version. The GH-XXX or GH-XXX-XX number on the motherboard determines the version.

Determining your version will help you find the parts you need. SCPH-XXXXX number refers to the number on the back of the PS2.

Models SCPH-39001/N and SCPH-50001/N are on the left side of the PS2. Slim models SCPH number is on the bottom. Date code refers to the small box near where the SCPH number is displayed. GH-XXX (big models) and GH-XXX-XX (slim models) refers to the number on the motherboard - The number is marked on the motherboard either right under the heatsink or on the bottom where the metal shielding is.

Please contact me if your SCPH or GH number is not listed and I will attempt to find out what version it is. If someone else sees this and knows other SCPH or GH numbers and what version they are please contact me via ebays messages system (perfectosolutions).
