Multitasking: Gaming while transcoding video
A number of readers over the years have suggested that some sort of real-time multitasking test would be a nice benchmark for multi-core CPUs. That goal has proven to be rather elusive, but we think our new game testing methods may allow us to pull it off. What we did is play some Skyrim, with a 60-second tour around Whiterun, using the same settings as our earlier gaming test. In the background, we had Windows Live Movie Maker transcoding a video from MPEG2 to H.264. Here's a look at the quality of our Skyrim experience while encoding.
So, who had the Pentium G2120 being the whipping boy here? Good call, although it wasn't hard to see coming. Disappointingly, the Trinity chips turn out to be slower than their older sibling, the A8-3850, in our latency-oriented metrics—and yes, folks, the Core i3-3225 is again quite a bit faster than any of 'em.
Civ V will run this benchmark in two ways, either while using the graphics card to draw everything on the screen, just as it would during a game, or entirely in software, without bothering with rendering, as a pure CPU performance test.
Either way you run it, the Trinity APUs are near the back of the pack, only ahead of their Llano predecessor.
