Ultra Violet Machines Genesis XOC Rules - 4. Gordian Knot and LameMT 

Written by Sanjin Rados

Review: The mother of all beasts powered by EVGA




Benchmark:

You have to keep in mind that different BIOS versions score different results. All tests were done with AUTO settings, with no BIOS tweaking except for CPU VCore, NB VCore and FST Termination Voltage.

For Genesis XOC testing we opted for comparison with previously tested motherboards, where we used Intel Core 2 Duo E6700 processor and an AMD ATI Radeon X1950XTX graphics card.


Gordian Knot/XVID 1.1.3:

For our Gordian Knot testing we took an PAL episode of "Babylon 5" with a total length of 41 minutes, 57 seconds and 8 frames.

We tried to "emulate" the most common usage of Gordian Knot:

1st: We have a perfect master, so we only de-interlace the content and resize it, with no other manipulation, we marked this as "fast".


2nd: You get bad mastering on many DVDs, especially "old" stuff or when the studios are in a hurry for the release. In this case you like to improve the picture quality, which is done by filtering the content. You can choose from tons of filters for any purposes you can think of, we only used the most common "undot", "FluxSmooth" and "MSharpen". Of course we also de-interlaced, filters were done before any resizing took place (which is slower). We marked this as "slow".

Gordian Knot doesn’t harness multi-core power for now, so our quad core QX6700 scores are no better than dual core processors. Genesis XOC runs at 3.50GHz, so we see the advantage of the overclocked processor.


LameMT

 

The same episode we encoded we also used for our MP3-testing. We don't recommend using MP3 for encoding, because AC3 can do the job better, and nearly 42 minutes gives us approximately the length of any given album.

A measurement in seconds, as many sites have, is useless, because the differences are too small. Therefore, we used the built-in play/CPU ratio which means the CPU is encoding x-times faster than the track-length. Fast memory does not play an important role here. For your convenience we also show you the single-threaded benches. They will be produced with any other L.A.M.E. version because only LameMT can do more than one thread and take advantage of a second dice.

We used the following settings: lamemt --vbr-new -q 2 -V 2 -m j --strictly-enforce-ISO --resample 48

Just like Gordian Knot, Lame also benefitted from the increased processor clock. However, although Lame benefitted from the second core, it’s still not optimized for quad core operation.
