AMD A10 and A8 Trinity APU: Virgo CPU Performance

Article Index:   

Test Setup and SiSoft SANDRA

Test System Configuration Notes: When configuring our test systems for this article, we first entered their respective system BIOSes or UEFIs and set each board to its "Optimized" or "High performance Defaults". We then saved the settings, re-entered the BIOS/UEFI and set the memory speed to each platform's maximum, officially supported speed--DDR3-1866 in the case of Virgo. The solid state drives were then formatted, and Windows 7 Ultimate x64 was installed. When the Windows installation was complete, we fully updated the OS, and installed the drivers necessary for our components. Auto-Updating and Windows Defender were then disabled and we installed all of our benchmarking software, performed a disk clean-up, cleared any prefetch and temp data, and ran the tests.

SiSoftware SANDRA 2012
Synthetic Benchmarks

We began our testing with SiSoftware's SANDRA 2012, the System ANalyzer, Diagnostic and Reporting Assistant. We ran four of the built-in subsystem tests that partially comprise the SANDRA 2012 suite with AMD's latest APUs (CPU Arithmetic, Multimedia, Memory Bandwidth, and Cache and Memory). All of the scores reported below were taken with the processors running at their default clock speeds with 8GB of DDR3-1866 RAM running in dual-channel mode on an Asus F2A85-M Pro motherboard.

Cache Latency Benchmark
 

Despite their new architecture and much higher base and Turbo frequencies, the AMD A10-5800K and A8-5600K offer only marginal improvements in performance over previous-gen products according to SANDRA. As the processor and multimedia benchmarks show, the A10-5800K and A8-5600K are only marginally faster than a Phenom II X4 965 and hang with older Core 2 Quads. Memory bandwidth is in the 11.1 - 11.4GB/s range, and like Bulldozer-based FX-Series processors, cache latency is unfortunately much higher than previous-gen products.
