Intel's New Core X CPU Comes With 18 Cores

The pricey top-of-the line Core i9 Extreme Edition is the first Intel desktop CPU to breach one teraflop of performance. It has less powerful and cheaper siblings, too.

A teraflop of performance in an Intel desktop CPU? Yes, please.

You'll need to shell out handsomely to get it, but Intel's new Core X processor family, unveiled on Tuesday, is designed to handle any task an extreme gamer or video editor can throw at it. Its flagship is the Intel Core i9 7980X Extreme Edition, which boasts 18 cores and and 36 threads. That chip will retail for $1,999, while the base Intel Core i5-7640X goes for $242.

In between are seven new processors, and in a bit of a departure from recent Core CPU lineups, each one offers a different core count, base clock speed, and Turbo Boost version. As you step up the price ladder, each rung adds two processor cores and four threads, topping out at 16 cores and 32 threads for the Intel Core i9-7960X, which retails for $1,699.

The more expensive the processor, the slower the clock speed too, at least in the initial tiers. That's due in part to Intel's improved Turbo Boost technology, which is designed to maximize both single-core and dual-core performance by choosing a "favored core" for each processing task. That means if you opt for the Intel Core i7-7740X, you'll get a 4.3GHz base clock speed that can increase to 4.5GHz thanks to Turbo Boost, while the Intel Core i9-7900X offers a base clock speed of 3.3GHz that can be boosted to either 4.3GHz or 4.5GHz thanks to the favored core selection.

Intel Core X comparison table

It's worth noting that we don't have availability details for each new processor SKU yet, nor did Intel announce the clock speeds or other specs of the Extreme Edition or the other top-of-the line Core i9 X-series CPUs. Still, the applications for the Core i9-series are clear: simultaneous video editing workloads like transcoding a file while you edit another one, or creating high-resolution graphics for use in virtual reality or 4K games.

If you've been waiting for chips that will let you perform these tasks and you have the budget to spend what amounts to $100 per processor core, you'll want to pore over the product sheets for more on the new Core X lineup. But many people will end up comparing the SKUs that Intel announced today with their AMD Ryzen equivalents. In some of the matchups, as Anandtech notes, the Ryzen chips come in a generation behind in terms of performance but significantly cheaper.

Managing Editor

I’m a managing editor at PCMag.com focused on PC hardware. Reading this during the day? Then you've caught me testing gear and editing reviews of Wi-Fi routers, printers, laptops, and tons of other personal tech. (Reading this at night? Then I’m probably dreaming about all those cool products.) I’ve covered the consumer tech world as an editor, reporter, and analyst since 2015.

I've covered most major consumer tech events, including CES, Computex, Google I/O, and IFA. I've also appeared on CBS News, in USA Today, and at many other outlets to offer analysis on breaking technology news.

Before I joined the tech-journalism ranks, I wrote on topics as diverse as Borneo's rainforests, Middle Eastern airlines, and Big Data's role in presidential elections. A graduate of Middlebury College, I also have a master's degree in journalism and French Studies from New York University.

The Technology I Use

While most people buy a phone or laptop and stick with it for years, I’m lucky enough to use devices based on Android, iOS, macOS, and Windows daily as part of my job. As a result, I cycle through lots of tech in addition to my IT-issue work laptop. (Yes, that's a ThinkPad.) Personally, I’ve also owned a lot of tech products both cutting-edge and cringeworthy, from the Nintendo GameCube and the original MacBook to the Palm m105 and the CueCat.
