eVGA Classified SR-2 review with Quad SLI GTX 480 on LN2 -
Performance ZLib CPU | Transcoding
ZLib CPU test
This integer benchmark measures combined CPU and memory subsystem performance through the public ZLib compression library Version 1.2.2
Some compression benchmark then, CPU ZLib test uses the basic x86 instructions, it is HyperThreading, and multi-core (CMP) aware. A very good test to measure multi-core performance among platforms.
Now check that out, and for the sake of it let's say you own a nice Core i7 920 based PC. At default clocks this setup is three times faster, and overclocked... well, just have a peek.
Multi-threaded Video Transcoding
Please do not compare the results above with numbers from our Guru3D reviews, Beaux ran into issues transcoding the Guru3D material, so he used a fairly simple movie and transcoded it to a film format 720P file. Unfortunately that also means a lack of comparative material. But since one X5680 is roughly equal to a Core i7 980X, you can keep that in mind and compare with it when overclocked.
The displayed number is the number of frames rendered per second averaged out over the encoding process. The higher the number, the faster the performance is. It's exactly in applications like these where processors with more cores really shine as they are all utilized to the maximum.
We test and review the eVGA Classified SR-2 motherboard. The SR-2 is a dual-socket Intel 5520 chipset based server motherboard dressed up for hardware enthusiasts and pro-overclockers. We'll smack two six-core Xeon X5680 processors on there, four GeForce GTX 480 cards, we'll cool them all with Liquid Nitrogen, overclock it... and see if we can break some records.
