AMD Phenom II X4 940 & 920: A True Return to Competition

Adobe Photoshop CS4 using Retouch Artists Speed Test
The Photoshop test does basic photo editing; there are a couple of color space conversions, many layer creations, color curve adjustment, image and canvas size adjustment, unsharp mask, and finally a gaussian blur performed on the entire image. The whole process is timed and thanks to the use of Intel's X25-M SSD as our test bed hard drive, performance is far more predictable than back when we used to test on mechanical disks.
For the type of image manipulations the Retouch Artists speed test performs, Intel's Core 2 and Core i7 CPUs are the better performers. Cache appears to have a very strong impact here; Penryn based Core 2s are around 8 - 10% faster than their 65nm counterparts.
Phenom II is 7.5% faster than the original Phenom here. The Phenom II X4 940 is unable to outperform its closest cost competitor, Intel's Core 2 Quad Q9400. The Q9400 is 9.5% faster. The same is true about the Phenom II X4 920 vs. Intel's Core 2 Quad Q8200/Q8300. While we only tested the Q8200, it's still 8% faster than the Phenom II X4 920.
With the new Phenom unable to be competitive here, the old Phenom doesn't fare any better. The Phenom X4 9950 is over 10% slower than the Core 2 Quad Q6600, the first quad-core we all fell in love with.
The benefit of four cores is higher than expected in Photoshop; looking at a dual vs. quad-core Penryn, there's around a 30% performance boost from moving to four cores at the same clock speed. If you use Photoshop a lot, quad-core is the way to go.

Those numbers are all correct, mate. I'm not sure why you'd be getting something different.Finally - Thursday, January 8, 2009 - link
Seriously guys, you should check out the new hard disk technology by Seagate. New density record, already available.kknd1967 - Thursday, January 8, 2009 - link
I thought Q9450 should be better with larger cache?Anand Lal Shimpi - Thursday, January 8, 2009 - link
In some of the tests the two will swap places simply because they run at the same clock speed and the added cache doesn't always help performance. In those cases if the Q9450 is behind it's most likely due to normal variation between test runs.Take care,
Anand

If I didn't have a 5000+ BE sitting in a K9A2 in my rig right now I probably wouldn't consider this CPU, but seeing as I do, it looks like I've found my next upgrade.kmmatney - Thursday, January 8, 2009 - link
I was on a plane flying back from Taiwan (I work in the Fab industry) and I happened to sit next to an Intel employee who had traveled to Asia for the Core i7 launch. I asked him about the small L2 cache, and he explained that these run about 300 test applications, and chose the cache amounts based on a compromise between performance (and latency) and die size. We talked a bit and he asked me how I knew so much about computer hardware, and I mentioned I'm an avid Anandtech reader. He recognized the name, and mentioned that he saw Anand argue with one of his coworkers for quite some time about the L2 cache size!Zaitsev - Thursday, January 8, 2009 - link
That's a great story! I would love to see anand duking it out with some intel employees! LOLslayerized - Thursday, January 8, 2009 - link
AMD has indeed made some notable improvements with Phenom II and their 45nm. Reviews keep mentioning about how there is an upgrade option with Phenom II being AM2 compatible; however, what next (this is probably their last product with AM2 compatibility)? Shouldn't the reviews consider the upgrade options for Core i7/X58 with Westmere in a couple of years too? For someone who is considering a fresh build, I think that is something that should be analyzed too imo. Great review otherwise as always; the playing field if not leveled is at least starting to look competitive in a few segments!!Griswold - Friday, January 9, 2009 - link
No. Facts and "might turn out that way in a few years" arent the same thing.san1s - Thursday, January 8, 2009 - link
still slower than core 2?
