Performance - AES data encryption | CPU Transcoding

AES data encryption

For this test we encrypt some precious data. Data encryption has become a sad necessity for responsible data managers. Cryptography is the science of secret codes, enabling the confidentiality of communication through an insecure channel. The AES algorithm uses one of three cipher key strengths: a 128-, 192-, or 256-bit encryption key (password). Each encryption key size causes the algorithm to behave slightly differently, so the increasing key sizes not only offer a larger number of bits with which you can scramble the data, but also increase the complexity of the cipher algorithm. AES encryption is applied in a lot of compressing software like WinZIP.

AMD processors always have been extremely good with AES (Advanced Encryption Standard) encryption in this particular test. Again nearly NIL difference in between the 965BE and the 965BE C3 on today's tested platform.

Transcoding over the CPU or GPU

We recently added another benchmark to the test-suite. It's MediaShow Espresso. The fun thing about this video transcoder is that it can utilize the GPU to assist it with the transcending process.  However, you can also solely use the CPU, making this a very interesting benchmark and you can check out behavior of CPU transcoding AND GPU transcoding all in one test.

Below you can find the first results of this new test. In this test we transcode a 200 MB AVCHD 1920x1080i media file to a 1280x720P MP4 binary.

As you can observe, very little results just yet. We recently introduced this test. As you can see the GPU is very well suited for this process. There's no performance difference in-between the two 965 processors and overclocked we gain a good step.
