Everest Ultimate
Everest is great for quick diagnostic of computer components and for checking some of the CPU's basic synthetic performance, as well as memory bandwidth and latency. Everest Ultimate version 530 is used to check the Memory Read/Write/Copy/Latency performance.
Based on the very good latency results it's obvious that AMD did some tweaks on the memory controller to optimize it for six core use, but from the rest of the results it's also visible that six cores put a lot of strain on the current generation memory controller. Luckily six is as far as it will go until AMD next-gen architecture.
