One supports 32-bit and 64-bit integer, FP16, FP32, FP64, and transcendental math functions, and the other supports only 32-bit and 64-bit integer, FP16 and FP32. 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 of the FP32 FLOPS.
FLOPS can be recorded in different measures of precision, for example, the TOP500 supercomputer list ranks computers by 64 bit (double-precision floating-point format) operations per second, abbreviated to FP64. [9] Similar measures are available for 32-bit (FP32) and 16-bit (FP16) operations.
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.
These results are used to compile the TOP500 list twice a year, with the world's most powerful computers. [1] TOP500 measures these in double-precision floating-point format (FP64). The ratio of R max to R peak is called parallel efficiency or HPL efficiency. [11] It is typically lower the more nodes a system has due to communication overhead.
Emerald Rapids is the codename for Intel's fifth generation Xeon Scalable server processors based on the Intel 7 node. [3] [4] Emerald Rapids CPUs are designed for data centers; the roughly contemporary Raptor Lake is intended for desktop and mobile usage. [5] [6] Nevine Nassif is a chief engineer for this generation. [7]
Intel Haswell Core i7-4771 CPU, sitting atop its original packaging that contains an OEM fan-cooled heatsink. This generational list of Intel processors attempts to present all of Intel's processors from the 4-bit 4004 (1971) to the present high-end offerings. Concise technical data is given for each product.
