Last year, Intel showcased a CPU during its keynote a processor with all of its cores at 5 GHz. Today, that becomes a reality – Intel is set to launch a processor that promises that frequency in any scenario. The new Core i9-9900KS is an 8-core processor that will run at 5.0 GHz during single core workloads and multi-core workloads.

That demo last year was on an overclockable 28-core Xeon CPU, but in reality was clocked way lower. There was even a good amount of controversy, as Intel didn’t state at the time they were using a sub-zero chiller to achieve that result. But this year we’re getting something a little more realistic. The new Core i9-9900KS uses the same silicon currently in the i9-9900K, but selectively binned in order to achieve 5.0 GHz on every core, all of the time.

Technically the CPU has a base frequency of 4.0 GHz, however it will only ever go down to that amount based on a default Intel BIOS (no consumer board uses the base BIOS specifications). The new CPU will be enabled in the same motherboards as the Core i9-9900K, but with a small firmware update. The CPU also has the same integrated graphics as the Core i9-9900K.

Intel did not tell us the TDP yet, but we will update this article when we know. Pricing and the launch date are also an unknown, however Intel SVP and GM Gregory Bryant is running a keynote here at Computex in a couple of days, and we expect to have the details then.

Update 05/28: As part of his Computex keynote, Gregory Bryant has confirmed that the processor is launching in Q4 of this year. Pricing and TDP will presumably be announced much closer to the actual launch.

i7-9700KF 8 / 8 3.6 GHz 4.6 GHz 4.9 GHz - 2666 95 W $374

The main difference compared to the Core i9-9900K is currently that all-core turbo value, which is a flat 5.0 GHz, a 300 MHz increase. There's a slight chance Intel might have increased the TDP, especially given that the base frequency (which TDP is built on) has increased 10% from 3.6 GHz to 4.0 GHz.

Why Intel Processors Draw More Power Than Expected: TDP and Turbo Explained

Intel did have a demo system for us to look at, which used a standard off-the-shelf motherboard and a closed loop liquid cooler. Intel confirmed that the chip is soldered, and that this is just simply the same silicon as the 9900K but better binned.

More info in a couple of days.

    Should be given on Tuesday at the keynote.

    Not a chance.

    It would be 95W when underclocked, and Turbo is disabled. Also with zombieland HT is useless so its just an overglorified i7-9700K.
  • IntelUser2000 - Sunday, May 26, 2019 - link

    The zombieland flaw is for pre 8th gen Core chips.
  • notashill - Sunday, May 26, 2019 - link

    They fixed it in *some* 8th gen chips. Specifically Intel64 Family 6 Model 142 Stepping 12, which does include the 9900K. But the "8th gen" U-series chips are a mix of stepping 10 and 11 and are not fixed.

    When the release first came out it was only fixed in Whiskey Lake and Atom CPUs not Coffee Lake based ones.
  • notashill - Sunday, May 26, 2019 - link

    Intel's generations are not very meaningful here. They claim to have fixed the issue in stepping 12 of all their current chip families, except Atom which didn't have the issue in the first place.

    There are "9th gen" chips that are stepping 10 and "8th gen" chips that are stepping 12. Some Coffee Lake chips are stepping 12 or 13, most are 10 or 11.

    Yeah, the fixed ones were all mobile or mostly. The chart/product line up was a bit convoluted. The side channel attacks don't seem to be in the wild yet, but I'm kind of glad I went with a 9700K.
  • GreenReaper - Friday, May 31, 2019 - link

    It gets worse because the MDS issues are only fixed in hardware in stepping 13. Frustrating that they didn't make separate SKUs. Does an i9-9900K have hardware protection for certain issues, or does it need performance-sapping firmware? Who knows! Surely the retailer won't tell you.
  • futurepastnow - Sunday, May 26, 2019 - link

    Don't think I'm going to take Intel's word on that.
