AMD A10-5800K 'Black Edition' Trinity APU - AMD Takes HSA to Newer Heights
Results - Cinebench 11.5 & Handbrake 0.9.4
Cinebench 11.5 Results
Cinebench is a rendering benchmark that's designed to use the CPU processing power and scales well to the degree of multi-threading support available on the processor. Below, you can distinctly see the performance band for true dual-core processors and quad-core processors. Since rendering applications are more floating point operation intensive and the AMD Trinity A10-5800K having only two such units, its performance falls in the class of true dual-core processors like the Intel Core i3-3220. The latter's Hyper-Threading capability to process up to four threads wasn't really utilized in this test scenario due to lack of spare resources (which is the premise of using this technology to better utilize the processor).
What's more surprising is that the older AMD A8-3850 Llano APU at slower clock speeds is marginally better than the AMD A10-5800K Trinity APU. Given the improvements at the core's processing blocks, you would expect Trinity to be speedier than Llano without second guessing, but this test says otherwise. If you noticed performance from the Lightwave benchmark, when using 4 and 8 threads to execute the test, the performance difference between both APUs were small. In fact, using the Sunset render scene, the older Llano was again a fraction better than Trinity - and that's despite the fact Llano operates at a much lower speed than the newcomer.
Handbrake 0.9.4 Results
On Handbrake, the disappointment was more pronounced as the A10-5800K lost out to the older A8-3850. Though the former did beat its Intel competitor by a margin of about 13%, it losing out to an older AMD architecture, casts some doubts about the new Piledriver architecture.
