AMD A8-3870K Black Edition & Hybrid Crossfire Review
Firstly it's worth pointing out that from the FX8150 down the OpenGL results were obtained on a GTX570, and from the rest on a HD7970. Even still the HD6550D gets its first test and performs much better than we'd anticipated. Certainly it is by no means disgraced. The CPU scores aren't bad either for a straight Quad Core, especially when we see how average the FX8150 results are.
POV-Ray has two major areas of comparison. The absolute speed, and the rendering speed available from each core. As we can see the overall performance isn't too bad when compared to some much more expensive hardware, and the per CPU score is right in the ballpark.
