Lavalys Everest 4.60.1540 Beta Memory Performance

Website: Lavalys



With the 200MHz increase in memory controller clock on the overclocked 7850 Black Edition, the overall effect in the raw benchmarks above is very little. In fact, the latency increases as the clock speed does, we think because of the increased difference in core-to-uncore ratio.

The improvement over the 7750 BE is negligible and clock to clock compared to the older Athlon K8s, there's actually less memory bandwidth available, but it does have 2MB of lower latency L3 cache to dive into. The memory bandwidth is significantly higher than the Intel parts, but Intel has compensated with a larger L2 cache and its specific core optimisations for reducing the reliance on memory access.
