We tested video encoding performance using VirtualDub-MPEG version 1.6.15 and a multithreaded version of the Xvid codec, along with the LAME MT MP3 encoder for encoding audio. We did a two-pass encode of a 15-minute 276MB digital TV recording with a target file size of 100MB.
The Kingston is again consistently faster than the OCZ, especially with low latencies at 1,066MHz. Remember these benchmarks are an average of three runs so the OCZ is consistently taking longer.
MP3 Encoding:
We used LAME MT for our audio encoding test - it's the multi-threaded version of the popular LAME MP3 encoder. We ran tests with both Intel's and Microsoft's compilers - naturally, the Intel compiler resulted in some performance increases on Intel's processors. We converted all 18 tracks from Moby's popular Play album to a 192kbps variable bit-rate MP3.
Just like before the OCZ outperforms the Kingston memory with low latencies but the situation reverses at stock speeds and there's very little difference between the respective overclocked performance. Unlike the file decoding, the MP3 decoding is far less clear cut with the OCZ coming out ahead in both low latency scenarios.
