Although AMD’s future is far from certain we do know that they have been pushing towards lower power and lower cost devices. We have seen these in the form of their new APUs and their A75 and A55 chipsets. We have already tested the performance of the A75, now we are ready to take a look at the performance of one of the A55 based motherboards; the Gigabyte A55M-DS2. We have taken a look at the design choices and features so far and have come away with a bit of confusion as to where this product actually fits into the market. Now that we have put the board through our performance tests, let’s see if we can find out exactly where in the market the A66M-DS2 belong and if it is worth your time and money.Section III - Performance Tests, Real-World
Here we have two tests that are designed to put the performance of the motherboard and its subsystems to the test. Both require good CPU, Memory, HDD and even to a lesser extent audio and network performance. The two tests we chose were Lightwave 3D 9.6 and AutoGK 2.55. We will be adding at least one more real-world test to this battery in the near future, but for now these two cover quite a bit.
Lightwave 3D 9.6 x64 -
Lightwave is another industry standard application for 3D animation and rendering. It has a large tool base and the rendering engine is highly threaded (when using the right render model). This application is also capable of expanding to 4k resolutions as well as ray tracing for rending the light sources. For our testing we use frame 470 of the Pinball scene found in the LW 9 Content folder. This uses the newer perspective camera that is better suited to a multi-CPU/Core environment. This camera style also uses ray tracing and a much improved anti-aliasing method. Settings are shown below in the attached screen shot. Of course these are single frame renders and they are not a complete picture; for that you have to take into account the number of frames an average project would have. In a typical 30 second commercial you will have around 840 to 960 frames (at 28 – 32 FPS) this means that you have to multiply the time of a single frame by that number just to get a vague idea of how long that 30 seconds would take. This is because each frame will have a different render time based on complexity.
As with the Cinebench scores, the Lightwave scores here only serve to show that you would not want to pick up the A6-3650 and A55 combination for rendering. The issue is the slow memory performance and caching. This is not a huge concern for the market that this APU/motherboard combination is for though. You might find the odd person that will want to run a higher end video effect application, but for the most part it is highly doubtful that the A3650 or any of the chipsets that support it will be spending time rendering 3D video at 4K resolutions. 
AutoGK 2.55 Transcoding -
AutoGK is a transcoding software that is really multiple parts combined to make an easy to use whole. It combines, items like FDD Show, Xvid encoder, Virtual Dub and others for use in converting one media format to another (usually Xvid AVI). It will not transcode copy protected DVDs or Bluray discs yet (you still need a decrypter for that). But it does an excellent job on everything else. For our testing we use a 2 hour movie that has been placed onto a standard definition DVD for playback; we then transcode this DVD to a 100% quality AVI with the original audio intact. This puts a strain on the CPU, Memory, HDD and the attached DVD ROM drive.
While the times we see for AutoGK are not especially fast, they are not terrible either. If you are looking into getting an AMD APU and an A55 board, I would honestly look into a transcoder that has a little less overhead than AutoGK. Of course you cannot beat the price on AutoGK (free is a great price).
