The Intel Core i7-990X Extreme Edition Processor Review

Features

We were impressed enough with Intel’s Sandy Bridge architecture that we awarded the Core i5-2500K our coveted Recommended Buy award. Just north of $200, that’s a solid value. But it’s not Intel’s flagship. That honor goes to the new Core i7-990X Extreme.

Conclusion

Two months ago, when I finished testing Intel’s Core i5-2500K and Core i7-2600K, I came to the conclusion that you’d have to be battier than Charlie Sheen with a suitcase of blow to spend $1000 on a Core i7-980X Extreme Edition in the face of Sandy Bridge-based CPUs. I was so convinced, in fact, that I didn’t bother benchmarking the super-exclusive chip, and instead focused on drilling deep into Quick Sync and Intel’s HD Graphics engines.

Now, in the face of a new flagship processor, we see that there are actually situations where a Core i7-900-series chip still makes sense. Frankly, enthusiasts and gamers need not apply. You can get so much value from the Core i5-2500K for $230 that it’s entirely worth waiting for new P67-based motherboards before you buy something new. Or, hold off for Z68, which will have some surprises of its own. The $770 you pocket as a result of not buying an Extreme Edition CPU buys a sick set of GeForce GTX 570s in SLI and a couple terabytes of storage.

But if your workstation is responsible for making you money; if it’s a true workhorse that you know for a fact muscles through threaded software like Premiere Pro, 3ds Max, and MainConcept (among others), then there’s a legitimate business case for buying the highest-end processor possible. And if you’re in that position, you can probably calculate exactly how long it’ll take for the Core i7-990X to pay for itself.

More so now than ever before, Intel’s X58 Express platform is being pegged as a 1P server/workstation configuration, and not a power user’s toy. There are limited reasons you’d actually want to spend $1000 on a processor in light of Sandy Bridge’s potency. The reasons are there though, and we’ve illustrated where you can expect to see them surface…

Win a Core i7-990X? We can make that happen.

…granted, it’d be a lot more fun to win Intel’s six-core flagship in a random giveaway, wouldn’t it? Well, we can make that happen—and all you have to do is enter. We’ve opened up the stash box, and here’s what we have:

  • 2 x Combo Intel Core i7-990X and Intel DX58SO2 Motherboard: Value of $1261
  • 1 x Combo Intel Core i7-980X and Intel DX58SO2 Motherboard: Value of $1261
  • 2 x Combo Intel Core i7-950 and Intel DX58SO2 Motherboard: Value of $556
  • 25 x one-month supply of Sparkling ICE water (two cases): Value of $54

The contest is going on between now and the end of the day, March 10th. Click here for the entry-sheet and a full list of rules.

    Chris, I think your first conclusion still valid.

    My friend just built a new gaming rig with the 980x as the processor... He plays Age of Conan. I busted up laughing when he said he spent $1k on a processor that he'll only use to 1/10th of its potential. Told him he should have gotten an i5, now I'll send him this article as further proof.

    This is just a ripoff by intel on those who are not knowledgeable enough that more expensive does not always mean better.

    Well, some people just want the best when they buy a PC, regardless of cost efficiency, can't blame 'em. There'll always be that market.

    Really wish it could be binoyski. We have specific tax laws, unfortunately, that prevent it. Same reason the folks in RI can't enter :-/

    Wow AMD's CPU is just getting plain-ol decimated in this review.

    Still, it does hold it's ground even though the architecture is like 4 years old, using the same technology that was around back when the C2Q's we're the high-end (the same as the original phenoms on a die shrink).

    Because of this, I can almost guarantee AMD's success with their future CPU's, just like I predicted the 2600K would be faster in most cases than the 980X.

    That doesn't mean I'm saying that Bulldozer will outperform the i7's or upcoming 8-core Intel CPU's I'm just saying that there's going to be some serious decisions for upgraders this year.

    I mean look at Magny corus 12 core (2.2GHz) vs i7 980x, it's almost as fast and 1GHz slower (but 12 physical cores) and cost's the same.

    joytech22Wow AMD's CPU is just getting plain-ol decimated in this review.i wouldnt say decimated, and its cheaper also. That benchmark of metro 2033 is interesting, particularly the better lowfps the AMD chip managed. But i agree they have flogged this horse as far as it will go and they need bulldozer ASAP to be competitive.

    I thought that's what Intel is doing with all of their CPUs :-)
