WebJul 18, 2016 · This is where cache coherency fits in. Preliminary benchmarking of CPU and GPU coherency shows up to 90% reduction in overheads relating to memory operations, according to Neil Parris, senior product manager at ARM. Hardware cache coherency can add some complexity to the IP, but it also can provide significant savings for system power.
