Compared to the original PS4 GPU, this is a 2.2775× or 227.75% 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.
In computing, half precision (sometimes called FP16 or float16) is a binary floating-point computer number format that occupies 16 bits (two bytes in modern computers) in computer memory. It is intended for storage of floating-point values in applications where higher precision is not essential, in particular image processing and neural ...
RGBE allows pixels to have the dynamic range and precision of floating-point values in a relatively compact data structure (32 bits per pixel) - often when images are generated from light simulations, the range of per-pixel color intensity values are much greater than will nicely fit into the standard 0..255 (8-bit) range of standard 24-bit image formats.
512-bit computing. In computer architecture, 512-bit integers, memory addresses, or other data units are those that are 512 bits (64 octets) wide. Also, 512-bit central processing unit (CPU) and arithmetic logic unit (ALU) architectures are those that are based on registers, address buses, or data buses of that size.
RGB color model. Web-safe color. v. t. e. Color depth or colour depth (see spelling differences ), also known as bit depth, is either the number of bits used to indicate the color of a single pixel, or the number of bits used for each color component of a single pixel. When referring to a pixel, the concept can be defined as bits per pixel (bpp).
The bfloat16 ( brain floating point) [ 1 ][ 2 ] floating-point format is a computer number format occupying 16 bits in computer memory; it represents a wide dynamic range of numeric values by using a floating radix point. This format is a shortened (16-bit) version of the 32-bit IEEE 754 single-precision floating-point format (binary32) with ...
I/O Memory: 2 MB EDO DRAM. CPU Core: Original PlayStation CPU (MIPS R3000A clocked at 33.8688 MHz or 36.864 MHz+PS1 GTE and MDEC for backwards compatibility with PS1 games) Automatically underclocked to 33.8688 MHz to achieve hardware backwards compatibility with original PlayStation format games. Sub Bus: 32-bit.
In computing, floating-point arithmetic ( FP) is arithmetic that represents subsets of real numbers using an integer with a fixed precision, called the significand, scaled by an integer exponent of a fixed base. Numbers of this form are called floating-point numbers. [ 1]: 3 [ 2]: 10 For example, 12.345 is a floating-point number in base ten ...
