Intel Core i7-980X Extreme 6-Core Processor Review

Introduction, Specifications, Related Links

Although they are not due to hit store shelves for a few more weeks, Intel is using the always exciting Game Developers Conference currently being held in San Francisco to officially unveil the new Core i7-980X Extreme processor. Intel's Extreme Edition processors have always been targeted at enthusiasts and hardcore-gamers, so what better place to show off the fastest desktop processor for the PC to date?  Unless of course you're catching it here on the pages of HotHardware, that is.

The new Core i7-980X Extreme is an interesting animal, however, that requires a detailed look. Although its branding implies that it may be just a simple speed-bump over the previous flagship Core i7-975 Extreme, the 980X is actually a totally different beast. And what a beast it is. While the Core i7-975 is based on the 45nm Bloomfield core and features quad execution cores, the new Core i7-980X Extreme is based on the 32nm Gulftown core and sports six execution cores.  That's right folks, quad-cores are no longer king of the hill.

There is much more to talk about with regards to Gulftown and the Core i7-980X Extreme specifically, but we're not about to cram it all into a pithy intro. Check out the specs immediately below and perhaps take a few moments to peruse some other recent Intel processor coverage a bit further down the page.  Then strap yourself in as we take the killer Intel Core i7-980X Extreme 6-Core processor for a spin...

32nm Gulftown 6-Core Wafer

The new Core i7-980X Extreme is based on the 32nm Gulftown core, which is derived from the 45nm Nehalem architecture that debuted with the original Core i7s. We've already posted a number of articles in the past detailing Nehalem in which we cover all its main features and specifications, and have even covered Gulftown a bit here and there. Due to the similarities between Gulftown and Nehalem, the two share many of the same capabilities.  We have written about Nehalem's features in depth in our coverage of the original Core i7 launch, we've posted information on overclocking Nehalem, even under extreme conditions, and have covered other 32nm derivatives as well...

We're going to summarize Gulftown's main features as they relate to the Core i7-980X Extreme again here, but if you'd like to check out our complete coverage of the Core i7 family and the X58 Express chipset which supports it, the list of articles above offers up just about all there is to know.
