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.
