Core i9-7940X - Intel
Template:mpu Core i9-7940X is a 64-bit tetradeca-core high-performance x86 desktop microprocessor introduced by Intel in mid-2017. This chip, which is based on the Skylake microarchitecture, is fabricated on Intel's 14 nm process. The i7-7940X operates at ? GHz with a TDP of 160 W and a Turbo Boost frequency of ? GHz. The processor supports up to 128 GiB of quad-channel DDR4-2666 memory.
Cache
- Main article: Skylake § Cache
Cache Organization
Cache is a hardware component containing a relatively small and extremely fast memory designed to speed up the performance of a CPU by preparing ahead of time the data it needs to read from a relatively slower medium such as main memory. The organization and amount of cache can have a large impact on the performance, power consumption, die size, and consequently cost of the IC. Cache is specified by its size, number of sets, associativity, block size, sub-block size, and fetch and write-back policies. Note: All units are in kibibytes and mebibytes. |
