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

The AMD we used to know and love is back. As I write this sentence, most of AMD is still on vacation. By the time you read this, that will have changed, but it's such a stark contrast to what happened when the original Phenom processor launched. In the months leading up to Phenom, AMD treated it like it would be its hero. "Just wait", we were told. So we did. And Phenom was the biggest disappointment AMD had ever left us with.
AMD re-launched Phenom the following year, in 2008, with slightly better reception. The CPU evolved from something unsellable to an honest alternative to Intel's CPUs, just not one we'd recommend. Phenom ran too hot, didn't offer better performance, and offered some strange behavior with Cool'n'Quiet enabled.
While AMD was very excited about the first Phenom, we heard relatively little about Phenom II. The first time we heard the name was at AMD's Financial Analyst Day a couple of months ago, and then a month later we had a chip. AMD invited us to overclock the CPU, but I was busy working on another AMD story at the time and couldn't make it. I was done with flying around for AMD CPU launches; if Phenom II was going to be good, the chip would have to prove itself without an exotic locale or delicious Texas BBQ to sweeten the deal.
And good it is.
AMD is launching two new 45nm Phenom II CPUs today. There's the Phenom II X4 940 at 3.0GHz and the 920 at 2.8GHz. I'll go ahead and say that although it's a little long, I like the name. The II just works. I'm also feeling a bit chipper, so I'll go ahead and give you the conclusion now too.
Here's how it breaks down. The Phenom II X4 940 is usually the same speed or faster than Intel's Core 2 Quad Q9400, and priced similarly at $275. There are some areas where the Q9400 will be faster than the Phenom II X4 940, so if you happen to use an application that runs better on Intel hardware then you've got your choice made out for you. But for the most part, if you're buying a quad-core processor at around $275 today, Phenom II will tempt you.
Similarly, the Phenom II X4 920 is generally better than or equal to Intel's Core 2 Quad Q9300, and priced less (it's more of a competitor to the slower Q8300, but I didn't have one available for testing). The same stipulations detailed above exist here as well; there are some areas where Intel is going to be faster but for the most part our tests showed the Phenom II to be a better option.
Wait, what? An AMD CPU recommendation?
After over two years of us recommending Intel's Core 2 lineup almost exclusively, AMD finally released a real alternative, one that's not just similarly priced, but actually higher performing than the price-competitive Intel part. Over the coming pages I'll explain how.
Now Intel could've spoiled the party, it still has the performance crown and it could easily drive CPU prices even lower. But out of the kindness of its heart, there are no unexpected price cuts, no new product introductions, nothing to spoil AMD's day (yet). While I'll talk about what Intel may do to restore its leadership at these price points, today is all about Phenom II. If you've been waiting for an AMD to be excited about for the past couple of years, today is your day.
Competition is back. Let's get to it.

Super, so because MS Vista has a really bad and stupid CPU scheduler, AMD had to disable perfectly legit and smart power saving feature = CnC per core rather than per chip. I really love windows! I expect that CnC per-core caused no problems under linux for example....CuE0083 - Sunday, April 26, 2009 - link
I have been a reader of this site for a few years (first time commenting) and I just wanted to know how you guys determine that a particular processor is a good overclocker.1) Do you guys try overclocking multiple chips?
2) Do you just walk into the store, pick a random chip, and try overclocking it?
3) Or does AMD send you a chip?

All this bickering and nick picking—when to me the solution seems simple.All the poor folks clamoring about numbers they COULD NOT EVER POSSIBLY tell the difference if using Intel Vs AMD in a dboule-blind test! None of you can tell the measurable diffs in FPS and temp. It's all little programs with numbers telling you there's a difference. So wtf is all the fus about?
Phenom-II is for people that already have an old AM2 rig and want to upgrade. But you forget that your old, slow ass mobo chipset and antiquated ram wouldn't even come close of a newer Intel system period.
A Brand NEW Phenom-II would "compete," but it barely does that. And as prices drop Phenom-II is losing even more ground as someone with an intel 775 can spring for a fast Quad-core, while you're stuck with the SAME OLD MOBO and RAM DERRRRR?
Stop all the nit-picking and bemoaning over Intel.
Does it make sense to scrap your current AMD rig for a completely new Intel unit?
YES = If you're doing video/AV editing and plan on getting an i7/i5 or if you’re not broke!
NO = If you currently have an AMD and need some extra horse-power.
But to falsely rationalize your purchase/mindset by suddenly putting the i7 into the "it's SO expensive" BS category; you're BROKE, you have no say about price. Get a real job and stop spending money on other nonsense and SAVE up like smart people do. It's YOUR own fault you cannot afford a damn $1100-1400 computer: that's NOT a lot. Just b/c YOU cannot afford it doesn't mean there's something "wrong" with i7.
You're comparing a 2yr old Q6600 against AMD's newest unit LOL? That's like a car magazine comparing the newest lambo to a 2 year old Ferrari etc. BUT PRICE OMG... Prices steadily go DOWN, thus folks with 775 can still upgrade to 6700, 6800 and so forth.
I'm glad AMD is "sort of" showing a rally to CATCH UP... BUT... when you buy into INTEL you're buying into a PROVEN ROADMAP OF PERFORMANCE VS AMD: you're buying into a mystery grab-bag of performance PROMISES.
Geesh. Just get the Phenom-II if you cannot afford the i7. Nobody with sense is talking about going from a Q6600/9xxx to 2 year behind the pack Phenom. This is just sophomoric nonsense.
Common-sense would tell you:
1) GET A BETTER JOB (education/certs etc)
2) Stop spending money on other hobbies and misc junk
3) STFU already and improve your financial situation, THEN you have a say. It's YOUR fault you don't have enough for a paltry $1200 machine. WHO doesn't have $1200? If you don't you haven't EARNED the right to complain. Complain b/c it's someone else's fault - I'm betting it's mostly your own lack of saving & discipline that's the problem.
None of you may like or agree w/me, but guess what? I don't care b/c I HAVE $1200 to spend so Fsck it I'm happy. Stop drinking, doing drugs, going out, blowing money on cable-TV and crap, for a change? Most of you are guilty of 1 or more of these frivolities.
Honestly THINK about what you’re saying here? You’re complaining about a superior i7 that is too expensive to do WHAT— play some damn video games? So your rationale is to do what? Buy a new or CPU upgrade to do the same? So THUS instead of continually saving to get the best… You BLOW your loads for inferior technology… and so the cycle continues. You’re NOW BROKE AGAIN and behind. Maybe you’ll start saving once again and come out of the wood work 2-3yrs later and STILL be complain once again “OMG it’s TOO EXPENSIVE” “I’ll by the cheap crap instead!”
LMFAO NOW THAT IS Ludicrous!

Are you serious dude?It ain't the money. I know. I have money. I also have a lambo a porche and an evo. I like testing AMD because they give us "certified" techs something to tinker with and work on. AMD is a brand for builders and true techs like to tinker with a processor and see how far it can go. Even when I was in high school I owned 486's which were the latest and greatest that time. I had an INTEL PC and it sucked dirt once Microsoft came out with windows. Maybe Intel is ahead now but AMD is catching up. They can create the ultimate processor but they don't have to. Not yet.
BTW, watch how you talk. Be considerate. It ain't the money man. I can afford to buy as many alienware pc's I want. But I don't. Am I a gamer? Yes! I have a powerful system now and am happy I did not spend a lot of money on it. See, this is the thing. If you are smart you just don't want to buy the fastest CPU and fastest RAM that comes out. It's like buying an PS3 for $6,000.00 on ebay just because you want to be the first to play it. That is stupid.
People buy AMD because they are tweakable. They try to buy the cheapest parts out there, tweak it, and see how far it can go. Makes sense?
So what if you have the fastest computer in the world. If you don't use it everyday you just wasted money.
Understand now kid. Now STFU and Go to your room!

I know that we should look at relative sysmark scores, but I'm still puzzled by the higher scores in this batch of tests, compared to those done in April 2008.For example the top performer from April - Core 2 Duo E8400 got a score of 161 on Overall in April 2008, and 191 in Jan 2009. The X4 Phenom 9750 went from 126 to 148. Other CPU's in both tests had similar differences. That's a bigger percentage difference than what gets used to debate whether Intel or AMD is better.
Anand - any comments on what caused such a large difference?

http://www.overclockersclub.com/reviews/phenomii94...">http://www.overclockersclub.com/reviews/phenomii94...After overclocking it really comes near and sometime it gets better performance them Core i7. Which is good. AMD has done superb job and they are in the right direction. Next black edition will make Intel so worry they have to go to work again.

Phenom II is showing power much better then here. To me it seems they have not done the testing properly. You better check out this link and find how its performing genuinelyhttp://www.guru3d.com/article/amd-phenom-ii-x4-920...">http://www.guru3d.com/article/amd-phenom-ii-x4-920...

The Q9400 are 126W~174W not like what Intel said 95W ?even E8600 (124W~157W) while they say 65W ?
their huge deferent in numbers here .

I think the new i7 core sucks compare Phenom II. Just look at the pricing vs performance on those two.Here is the benchmarks http://www.overclockersclub.com/reviews/phenomii94...">http://www.overclockersclub.com/reviews/phenomii94...

You do the overclocks but don't show us the results? Following overclocking, those stock processors have WIDELY different capabilities.I'd love to see those video encode charts redone with the overclocked processors. That would tell me the TRUE value of the 64x2BE, C2D, Phenom, PhenomII, and i7 relative to one another.
Otherwise, your overclock information borders on worthless.
