AMD Kaveri Review: A10-7850K, A10-7700K and A8-7600

Memory Performance

AIDA 64 Engineer

AIDA64 Engineer is a streamlined Windows diagnostic and benchmarking software for engineers. It has unique capabilities to assess the performance of the processor, system memory, and disk drives. AIDA64 is compatible with all current 32-bit and 64-bit Microsoft Windows operating systems, including Windows 8 and Windows Server 2012. Memory and cache benchmarks are available to analyze system RAM bandwidth and latency. Download here.

Memory read performance showed little uplift across generations or thermal envelopes and there is still a significant gap between AMD’s APUs and Intel’s Haswell architecture that needs to be bridged.

In memory write we saw a significant jump in performance of about 25% but the performance of AMD’s APUs in memory write quite literally pales in comparison to Intel’s Haswell CPUs.

The story with memory copy is a different one to both memory read and memory write. AMD’s Kaveri APUs show strong generational improvements over Richland and they are also doing well to close the gap on Intel’s Haswell.

Latency revealed some very concerning numbers with Kaveri being a full 30% slower than Richland and about 50% slower than Haswell. Kaveri has actually become significantly worse in the area of memory latency. Even Richland’s slowest part delivered better latency than the fastest Kaveri part.
