TrueCrypt disk encryption
TrueCrypt supports acceleration via Intel's AES-NI instructions, so the encoding of the AES algorithm, in particular, should be very fast on the CPUs that support those instructions. We've also included results for another algorithm, Twofish, that isn't accelerated via dedicated instructions.

7-Zip file compression and decompression

SunSpider JavaScript performance

Trinity's hardware AES acceleration gives it a massive lead over Llano in our first TrueCrypt test. Elsewhere, the differences are smaller. We do see a sizeable improvement from the A8 to the A10 in SunSpider, though, which is a very good thing. You might not compress or decrypt files everyday, but most of us spend a big chunk of our day using JavaScript-heavy websites and web apps. The A10 promises to be solidly faster than the A8 in those.

Neither AMD APU can catch up to Intel's quad-core offerings, of course, but that's no great surprise. We didn't expect AMD to catch Intel in raw CPU performance, especially not with a 10W power envelope handicap. Still, Trinity will have to do well on other fronts to distinguish itself.

Image processing

The Panorama Factory photo stitching
The Panorama Factory handles an increasingly popular image processing task: joining together multiple images to create a wide-aspect panorama. This task can require lots of memory and can be computationally intensive, so The Panorama Factory comes in a 64-bit version that's widely multithreaded. We asked it to join four pictures, each eight megapixels, into a glorious panorama of the interior of Damage Labs.

In the past, we've added up the time taken by all of the different elements of the panorama creation wizard and reported that number, along with detailed results for each operation. However, doing so is incredibly data-input-intensive, and the process tends to be dominated by a single, long operation: the stitch. Thus, we've simply decided to report the stitch time, which saves us a lot of work and still gets at the heart of the matter.

Video encoding

x264 HD benchmark
This benchmark tests one of the most popular H.264 video encoders, the open-source x264. The results come in two parts, for the two passes the encoder makes through the video file. I've chosen to report them separately, since that's typically how the results are reported in the public database of results for this benchmark.

We see the same story unfold in our image editing and video encoding tests: the A10-4600M edges out the A8-3500M by a decent margin, but it's no match for quad-core Sandy and Ivy CPUs.
