A8-7680 is a 64-bit quad-core low TDP x86 desktop microprocessor introduced by AMD in early 2019. This processor is based on AMD's Excavator microarchitecture and is fabricated on a 28 nm process. The A8-7680 operates at a base frequency of 3.5 GHz with a TDP of 65 W and a turbo frequency of 3.8 GHz. This APU supports dual-channel DDR3-1600 memory and incorporates AMD Radeon R7 series graphics operating at up to 720 MHz.

[Edit/Modify Cache Info]

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.
