Thus the FP16 (or 16-bit integer) FLOPS is twice the FP32 (or 32-bit integer) FLOPS. Since the throughput of FP64 instructions are 2 cycles, the FP64 FLOPS is a quarter (eighth in Apollo Lake) of the FP32 FLOPS. Each Subslice contains 8 EUs (two of which are disabled in GT1) and a sampler (4 tex/clk), and has 64 KB shared memory.
Double-precision floating-point format (sometimes called FP64 or float64) is a floating-point number format, usually occupying 64 bits in computer memory; it represents a wide range of numeric values by using a floating radix point. Double precision may be chosen when the range or precision of single precision would be insufficient.
Floating point operations per second (FLOPS, flops or flop/s) is a measure of computer performance in computing, useful in fields of scientific computations that require floating-point calculations. [1] For such cases, it is a more accurate measure than measuring instructions per second. [citation needed]
The performance measured by the LINPACK benchmark consists of the number of 64-bit floating-point operations, generally additions and multiplications, a computer can perform per second, also known as FLOPS. However, a computer's performance when running actual applications is likely to be far behind the maximal performance it achieves running ...
Support for half precision in the x86 instruction set is specified in the F16C instruction set extension, first introduced in 2009 by AMD and fairly broadly adopted by AMD and Intel CPUs by 2012. This was further extended up the AVX-512_FP16 instruction set extension implemented in the Intel Sapphire Rapids processor.

RapidCAD is a specially packaged Intel 486DX and a dummy floating-point unit (FPU) designed as pin-compatible replacements for an Intel 80386 processor and 80387 FPU. Because the i486DX has a working on-chip FPU, a dummy FPU package (the "RapidCAD-2") is supplied to go in the Intel 387 FPU socket. The dummy FPU is used to provide the FERR ...
(Quadruple-precision REAL*16 is supported by the Intel Fortran Compiler [10] and by the GNU Fortran compiler [11] on x86, x86-64, and Itanium architectures, for example.) For the C programming language , ISO/IEC TS 18661-3 (floating-point extensions for C, interchange and extended types) specifies _Float128 as the type implementing the IEEE 754 ...
