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

SYSMark 2007
Our journey starts with SYSMark 2007, the only all-encompassing performance suite in our review today. The idea here is simple: one benchmark to indicate the overall performance of your machine.
AMD hasn’t done too well under SYSMark 2007, especially with Phenom - it was just never competitive. There were even murmurs of AMD complaining about its poor performance under SYSMark 2007 not too long ago. The complaints never went anywhere because Phenom II addressed the shortcomings. SYSMark 2007 favors larger caches and the original Phenom left its cores cache-starved. With 1.5MB of L3 cache per core, Phenom II now offers the same performance as its closest cost competitors under SYSMark 2007.
The Phenom II X4 940 gets the exact same score as the Core 2 Quad Q9400. The Phenom II X4 920 equals the performance of the Q9300, which is actually a bit more expensive than AMD’s proposed price. If the two were competing against the Q9550 and Q9400, respectively, AMD would go back to trailing Penryn.
The older Phenom processors are mostly worthless here - Intel’s Core 2 Quad Q6600 outperforms the Phenom X4 9950 by 8%, and that’s with CnQ disabled. Turn on CnQ and the performance gap grows to a noticeable 25%. One of the biggest advantages of Phenom II is that you can have CnQ enabled without the painful performance impact.
It’s worth pointing out the sort of performance you can get out of a high frequency dual-core CPU here. The Core 2 Duo E8600 is a bit expensive for a dual-core, priced at $266, but it offers the same performance as the Core 2 Quad Q9650. The more affordable Core 2 Duo E8400 runs at 3.0GHz, priced at $166, and outperforms all sub-2.66GHz quad-core Core 2 chips. While a quad-core will last you longer, if you are a frequent upgrader it’s worth paying attention to the dual-core market. An E8400 today, followed by a mainstream Nehalem next year, could be your path to performance enlightenment.

fanboys help keep them alive.if more ppl started looking at AMD again, then Intel will be scared, so us the consumers will be happy because of prices.
intel has been greedy and overpriced their c2 because there was no competetion at that time.

I generally buy AMD processors for two reasons. The first is that I am not a gamer so I'm looking for cost-effective business application solutions. I'd rather double the memory than increase the processor speed, so AMD works well at the price points I build to.Secondly, I believe in the need for competition. With the power PC processor virtually absent from the consumer market and there being little else to choose from for the desktop market, AMD is Intel's only real competitor. So long as AMD has chips that are good enough to compete with Intel's on price/performance, I prefer to buy them.
If Via got their Cyrix processors up to a decent speed, I might be tempted to switch to them, but let's face it, they don't really compete in this market. So in a two-way race, we need to put our money behind the underdog to prevent a monopoly.
I've been buying ATI cards too for similar reasons. Nice to see that AMD's making advances in both areas.
To be clear, I've got nothing against Intel, at least not since the Pentium fiasco, but I think everyone will agree that having multiple firms competing is better for consumers than having one company dominate (Windows 95, 98, Millenium Edition, Vista come to mind). :)

Much of your post should go next to the Webster definition of "AMDfanboi"If you want true competition, buy the better product. I got my sweet A64. I will now consider P2 over a C2D, but because of price/performance/watt alone.

"Blender is one of the few tests that doesn't strongly favor the Core i7, in fact it does not favor them at all. Here the Core 2 Quad Q9650 is the fastest processor, followed by the Phenom II X4 940 and the Phenom II X4 920."http://www.techspot.com/review/137-amd-phenom2-x4-...">http://www.techspot.com/review/137-amd-phenom2-x4-...
"Blender shows Phenom II less competitive than the other 3D rendering tests we've seen thus far."

Both can't be true. Explanations would be highly appreciated. I suggest, that anandtech ask techspot about the test settings. Blender is capable of using several threads but I'm not sure wether the optimization is automated. Please, play with the settings. For example, 8*8 (render) tiles can benefit from 8 threads while 1*1 can't.

How much money has paid Intel to you for this "testing"? You have tested productivity of processors only on two games. In both games productivity of Core 2 is above. In one of them much more above, but it happens seldom. Other tests show, that productivity of Core 2 Quad in part of games is above. In part of games productivity Phenom II of same frequency is above. Why there is so a lot of coding and synthetic tests where Intel is faster, and as always there are no other applications? Why you continue to say lies, as earlier liars for money of Intel that Northwood is ostensibly faster, than Barton.strikeback03 - Friday, January 9, 2009 - link
I'm surprised how long it took the fanbois to start commenting on this article. Didn't really get rolling until several pages into the comments.JimmiG - Friday, January 9, 2009 - link
Bit disappointing that it's still slower than Core2 clock for clock. But given the performance of the original Phenom, I think the CPU performs as expected. A big leap for AMD. Unfortunately for them, Intel made an even bigger leap when they switched from Netbust to Core2.Also a bit concerned about this supposed "backwards compatibility". Many of the original 790FX boards, my M3A32-MVP Deluxe in particular, will not work with AM3 CPUs because Asus does not plan on releasing a BIOS update. Of course that's the fault of second-rate mobo companies like Asus, and not the fault of AMD. I'll probably end up getting a DDR2 PII-940 to replace my X4 9650, but I'll wait until the prices have dropped some.

Just wait till Am3 socket comes out, Intel will have to make a slight cheaper version of x58chipset. Is that sweat i see on their forehead?Amd buy Via's Nano and give them a 2 prong attack.

AMD has gone a long way to improving the performance of its processors, and everyone should go out and buy them. They need our support, and without it we will have to put up with whatever Intel decide to give us. And everyone here I think remembers the P4 days, let them not come again!The AM2 /2+ /3 platform is by far the easiest upgrade option. No need to worry if your NB chipset supports the latest FSB or RAM, because its all integrated into the CPU. A feature than Intel has copied in its new i7. Along with the monlithic quad core design, and level 3 cache. Also do not forget that AMD released the first x86-64 CPU, and intel basically complied to its x86-64 code to be compatible with the software developed for it.
i7 is fast, very fast. But do you need that kind of performance in your everyday life? i7 is designed for workstation's hence the benchmarks of video encoding and 3D applications. Gamers would be better off getting a top of the line GPU. Is your CPU 100% utilized 24/7?
I saw a comment about the 2 year old Core 2 Quad being faster, only in Far Cry 2, that one test. And I would rather play Crysis anyday.
Since its release Intel has tweaked the performance of these with new cores no end.
Sorry I digest.... lol
Keep things competitive, buy AMD. Fanboy or no, let the price wars rage on.

1. Most people use their everyday system to *work* too.2. Dont compare i7 to P2. Youll just look like youre really reaching and a fanboy.
3. You dont -Need- anything better than a A64 for everyday tasks. Depending on how long you wanna wait though, you will go to a better system. That point about not -needing- better hardware has always been ridiculous and only applies to grandmas and people that use the computer for browsing and music. Those people dont care about this area in computer so its moot!
P2 is great, but be realistic. Its competing against C2 right now. Comparing technicalities and -who was firsts- doesnt provide more FPs in anything. It just makes for flame fodder. The numbers speak for themselves and I think this article did a good job in putting the P2 in its place. As a great alternative for people looking to upgrade from older than C2 hardware.
