What's your CPU compression rate

Cheers chap! I shall have a butchers in a min

Got a game running in the background, not sure if it makes a difference, but i was expecting higher, a little disappointed

A really stupid question coming up, drum roll please...

What is CPU compression?

What is CPU compression?

Gary linked an explanation here mate

Does anyone know what it's actually measuring? I'd got a load of browser tab's, you tube video and Procon running when I tested.

Here's a fairly simple explanation Ryan, I didn't know either.
PassMark CPU Benchmarks - CPU Test Information

This is my i7-3770K rig, My i5-2550K got a 576.4MBs.

What is CPU compression?

As stated in Gary's link

The Compression Test measures the speed that the CPU can compress blocks of data into smaller blocks of data without losing any of the original data. The result is reported in Kilobytes per Second. This test uses complex data structures and complex data manipulation techniques to perform a function that is very common in software applications, ranging from backup software to Email software. The compression test uses an Adaptive encoding algorithm based on a method described by from Ian H. Witten, Radford M. Neal, and John G. Cleary in an article called “Arithmetic Coding for Data Compression”. The system uses a model which maintains the probability of each symbol being the next encoded. It reports a compression rate of 363% for English text, which is slightly better than the classic Huffman method. This tests uses memory buffers totaling about 16kb per core.

OK the cpu compresses data to enable it to deal with less data. This assumes that it's faster to compress and deal with the compressed data than to deal with non compressed data. Does compression mean something like zipping a file or trunjating data that the processor does not need?

 

[jmichae3]

"cpu compression" is the wrong title. "file compression cpu test" would be more descriptive and accurate I think. to my knowledge, the i7 doesn't have compression instructions. this is done through software.
zipping a file is basically the same thing. except with this you time it.

Great! Thank you all for your replies

That's top'o'the board Paul.

Here be mine.

My 3770K at 4600, I think. EDIT: Yes 4600, just checked.

Robert if you press ALT+PRNTSRN it will capture only the active window to paste in Paint.

The Ivy E looks like a powerhouse Paul.
