Power Consumption Comparison

Except for an APU with slightly higher clock speeds, the hardware inside the Edge HD3 is very similar to configuration of the Viako ML-45 barebones nettop we reviewed several months ago. The two systems consumed nearly identical amounts of power at idle and H.264 video playback, but the Sapphire used 4~5W more on load. It was still more energy efficient than than previously tested ION configurations of the Zotac ZBOX and Asus Eee Box.

CPU Performance

The Edge HD3 is powered by an AMD E-450 APU with the same dual core CPU as the E-350, only a scant 50 MHz faster. We don't expect any significant performance differences.

The E-450 was faster to the tune of 5~6% in some of our tests, but the overall performance level is still far behind that of Intel's CULV Celeron SU2300 which based on the Core 2 architecture. An E-series chip is a big step up from an Atom processor, but not as speedy as a modern desktop CPU.

3D Performance

The HD 6320 graphics chip is as you would expect, an iterative improvement over HD 6310, offering a small boost in core clock speed. With only 80 shader units and relatively low core and memory speeds, the HD 4350 is its closest desktop competitor.

In 3DMark05/06, the Edge HD3 achieved scores 20% higher than the E-350 based Asus E35M1-M motherboard, while the improvement in our H.A.W.X 2 and Lost Planet 2 benchmarks was 9~10%. An extra two frames per second at 1366x768 doesn't really change the overall gaming experience.
