Final Words

Architecturally, Phenom II is what the original Phenom should have been. It's not cache starved, and while not as balanced as Core i7, it's a step in the right direction.

Compared to the Core 2 Quad Q9400, the Phenom II X4 940 is clearly the better pick. While it's not faster across the board, more often than not the 940 is equal to or faster than the Q9400. If Intel can drop the price of the Core 2 Quad Q9550 to the same price as the Phenom II X4 940 then the recommendation goes back to Intel. The Q9550 is generally faster than the 940, more overclockable at lower voltages, and a high enough default clock speed to keep you happy in the long run.

The same goes for the Phenom II X4 920 vs. Q9300/Q8200; AMD wins that comparison at the same price point. Compared to the Q9400, the Phenom II X4 920 falls behind. The Q9400 is the better buy of the two, but only if Intel does come through with rumored price cuts. We'll know for sure by the end of the month.

AMD also thankfully produced a good overclocker, at least with our review samples. The fact that we weren't able to overclock too high without increasing the core voltage is a testament to the early nature of AMD's 45nm process. Core i7, on the other hand, was basically able to reach maximum clock speed without so much as touching the voltage dials. Remember that Core i7 is Intel's second 45nm processor while Phenom II is AMD's first; it will only get better with time.

Looking through the performance results, it's also worthwhile to recognize just how fast Intel's Core i7 is. Across the board Core i7 is the fastest thing out there. If the motherboard guys could get X58 board pricing down below $200 and DDR3 memory was available at the same price as DDR2, then the i7-920 would be the clear recommendation. The entry-level Core i7 is pretty much faster than the-top end Core 2 Extreme or the Phenom II. When I originally reviewed Conroe I wrote that it was the world's fastest microprocessor; Core i7 continues to hang on to that title.

Despite Intel's strengths, AMD was able to do very well here today with Phenom II. Being able to have a CPU competitive with Penryn right out of the gates is worthy of a commendation. The scary part is that Intel could easily mitigate AMD's gains here with some simple price adjustments. Even more worrisome for AMD is that Phenom II is its only foot forward until 2011 when the first Bulldozer based CPUs arrive. There's headroom in AMD's 45nm process, but what happens when Core i7 goes mainstream? We must not forget that Phenom II is competitive with a 45nm derivative of a 2+ year old architecture.

If you have a Socket-AM2+ motherboard with BIOS support for Phenom II there's no question - Phenom II is the best upgrade path for you. If you are trying to build a new system from scratch, I'd suggest waiting for either the Socket-AM3 CPUs or see what Intel does with its pricing later this month.

Phenom II is AMD's return to competition, and unlike the best the original could do, the sequel is actually worthwhile. Even if Intel drops prices to maintain control of the quad-core market, you have AMD to thank for that. It's similar to what happened in the GPU market last summer: competition keeps prices in check. Economic woes or not, both AMD and Intel are going to be fighting hard for your business this year.

    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.... Reply

    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?

    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 genuinely

    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.
