AMD Phenom II X4 955 Black Edition - Image Editing and File Compression

By Edward Chester



Our Score:


Photoshop Batch Processing

For this test we run all the auto-adjustments available in Photoshop on a large collection of images and time how long it takes to complete. It's an old test that isn't multi-threaded but it is incredibly reliable at demonstrating differences in single-threaded performance.

WinRAR File Compression

Though zipping and unzipping files is a fairly quick and easy task, the frequency with which a heavy computer user has to do it means saving five seconds each time you unzip something is a real boon. We therefore feel it makes for an interesting test of system performance.

This test is split into two parts. The first times how long it takes to compress a large video file and the second records how long it takes to compress the folder of photos used in the above Photoshop test. We then repeat this test using the multithreaded version of WinRAR.

Looks good. FYI all the charts in your review say 810 not 955 Black Ed.

Cheers, I think they should all be fixed by now.

no conclusion!?

aww :(

You're right, we only did a 'verdict' on page 3. My bad. ;)

Talk about wanting it on a plate! Overclocking used to be a bit of a black art. Soldering resistors, joining tiny bridges with conductive paint, using the right memory and tinkering with timings and voltages, fiddling with motherboard jumpers, flatting/polishing the cpu heatspreader and huge heatsink, screaming fans, all to get a few extra Mhz. I sweated blood to get a P75 running at 90Mhz on an Asus CUSL2 !

You guys get 3.8Ghz (nearly a 20% overclock) at stock voltage without lifting a finger and moan about it. How hard could it be to raise the voltage 0.1V to see if it would hit 4Ghz? Or more.

Other than that good cpu and great review ;)

As I explained, the system was essentially dead after some initial attempts and due to time constraints we weren't able to recover it for another run. Reading around, these will easily hit 3.8 on stock voltages, and are reasonably likely to reach 4 with a bit of extra voltage. Beyond that you need some serious cooling.

Nevertheless, the point I was making was that the 3.2 to 3.8 overclock we achieved was lower than the 2.8 to 3.41 we achieved with the Q9550 (both without changing any voltages) - a CPU that proved to be generally faster despite its lower clock speed. So the overclocking potential of the 955BE has to be taken with a pinch of salt.

I belive there is missclick - should be 6mb L3 cache instead of 2mb on page 1.

May i ask about cooling? Did you use components included in box or add your own cpu cooling? Was thermal paste included in box? What was temperature when oc to 3.8?
