Intel debuts 9th-generation Core chips, including Core i9 and X-series parts, with a few twists

Hyper-Threading suddenly becomes scarce, and the stunning 28-core chip is Xeon only.

Intel unveiled its 9th-generation Core desktop chips (after weeks of speculation and leaks), with the notable omission of a key feature: Hyper-Threading, at least on all but the most exclusive Core i9-9900K for mainstream PCs. Hyper-Threading has also been reserved for a new iteration of Intel’s X-series processors, which includes up to 18 cores and 36 threads. 

In a livestream Monday morning from its Fall Launch Event in New York, the company announced just a single Core i9 chip, the $488 Core i9-9900K, Later, the company privately revealed two others in the Core i7 and Core i5 families. 

Intel also announced a new series of X-class chips, ranging from 8 cores and 16 threads through 18 cores and 36 threads. Prices will range from $589 to $1,979.

What this means: It's certainly fair to say that Intel surprised us all with the unexpected shift of its upcoming 28-core chip to the Xeon family, as well as the announcement of the X-series chips, too. And what's the deal with hyperthreading? Intel's announcement certainly adds some new topics to talk about in the months ahead.

Part of the confusion was due to what Intel was expected to announce: a family of new 9th-gen chips, from Core i3s up through the Core i9, and how it did so. On the publicly available livestream, the company revealed only the presence of the Core i9-9900K, as well as the presence of the new X-series parts. Later, after the livestream had concluded, Intel fleshed out the remaining members of the K-series parts, and disclosed the price and performance of the X-series parts.

However, Intel didn’t even mention what many enthusiasts wanted to know: why only the i9-9900K, out of all of Intel’s mainstream parts, boasts the Hyper-Threading feature.

Hyper-Threading is now an Intel gaming feature

Hyper-Threading, of course, has been a staple of Intel’s processors since 2002’s Pentium 4. As clock speeds tended to top out at 4GHz to 5GHz, parallelism—originally in the form of support for more processor threads, and later to more physical cores—kept the processor performance on an upward trajectory. 

Rival AMD made multi-core chips a staple of its success with Ryzen and its Threadripper parts, with a massive 32-core, 64-thread 2nd-gen Threadripper already on store shelves. Game developers, though, have been slower to keep up, with most using just a handful of the available threads. That’s made Hyper-Threaded, multi-core chips more suitable for video editing and rendering, rather than everyday PC workloads.

Another factor is Intel’s own manufacturing problems. No, these new chips aren’t Intel’s long-awaited launch into the 10nm generation. The new “Coffee Lake Refresh (-R)” chips Intel announced Monday are still built upon a 14nm process, in might what be called a “14nm++” process technology.

By now, Intel expected its 10nm fabs would be churning out new “Cannon Lake” processors, reserving the 14nm production lines for older chips. But the slow transition forced Intel to change direction, and Intel has said its production will suffer. Fortunately, the company is prioritizing high-end Core chips.

Anand Srivatsa, vice president and general manager in the Client Computing Group at Intel, introduced the new 9th-gen parts. “We know that the PC is already great in enabling performance to create, to connect, and we intend to build on these strengths,” Srivatsa said. 

Srivatsa began his presentation with an apparent surprise: Intel appears to be calling its upcoming 28-core chip that it announced at Computex the W-3175X Xeon, a part that runs up to 4.3GHz—and not a member of the Core family. It will include 68 platform PCIe lanes. It will ship in December, Srivatsa said, at an undisclosed price. 

Srivatsa also highlighted Intel’s existing 14-, 16-, and 18-core Intel’s X-series chips as a part for creators, of which Intel said there are 100 million in the U.S., the U.K. and China combined. Intel announced several parts, listed below. They’ll ship this November.

  • 3.0GHz (4.4GHz turbo) 18-core/36-thread Core i9-9980XE, for $1,979
  • 3.1GHz(4.4GHz) 16-core/32-thread Core i9-9960X, for $1,684
  • 3.3GHz (4.4GHz) 14-core/28thread Core i9-9940X, for $1,387
  • 3.5GHz (4.4GHz) 12-core/24-thread Core i9-9920X, for $1,189
  • 3.5GHz (4.4GHz) 10-core/20-thread Core i9-9900X, for $989
  • 3.3GHz (4.1GHz) 10-core/20-thread Core i9-9820X, for $889
  • 3.8GHz (4.4GHz) 8-core/16-thread Core i7-9800X, for $589

Intel also released performance metrics for the new chips.

Here’s how the new 9th-gen X-series parts are expected to perform.

Everyone was waiting for the mainstream desktop parts. The company introduced its first 9th-gen chips, spearheaded by the Core i9-9900K. It's the company’s first broad-volume 5GHz chip, with 8 cores and 16 threads. Intel is also adding solder TIM for additional overclocking headroom. 

To demonstrate its processing power, Intel took a Core i9-9900K, placed a pair of virtual machines on it, and gamed and streamed Player Unknown: Battlegrounds on the system. “The Core i9-9900K: best gaming processor in the world, period,” Srivatsa said.

From a security standpoint, there’s another plus: The new 9th-generation parts contain some of Intel’s first mitigations in hardware to solve the Meltdown bug, the company said. 

Intel announced three members of the new 9th-gen K series:

  • 3.6GHz (5.0GHz) 8-core/16-thread Core i9-9900K, for $488
  • 3.6GHz (4.9GHz) 8-core/8-thread Core i7-9700K, for $374
  • 3.7GHz (4.6GHz) 6-core, 6-thread Core i5-9600K, for $262

Starting today, Intel said, you can preorder the Core i9-9900K. The Acer Predator, the Asus ROG line, the HP Omen, and the Dell Alienware lineup will all use it.  Users can also go to Corei9.Intel.com for free codes and other prizes.
