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.

    Still not clear on the exact relationship between base and turbo. When will this chip run at base vs the latter? Reply

    Base frequency is when the Tau moving window time has expired. How most modern high end motherboards set it to an effective unlimited time. Check the link to the TDP article. Reply

    At what voltage does it do 5ghz allcore. With what uncore. What about AVX. Is "all the time" really all the time. Reply

    Going by the fact it's the same silicon, just binned as stated by the rep, uncore and AVX remains the same. And as usual with AVX, that's always excluded from the all core turbo as that always brings the rest of cpu performance/clocks down. Most overclocks on the 9900k usually use -2 offset or more to hit the all core clocks. As for voltage, I really wonder myself if they actually keep at original voltage or need to bump it up. Most 9900k have trouble OC'ing to 5ghz without pushing voltage up and subsequently lots and lots of heat. Reply

    So, since almost everything uses AVX nowadays, NOT "Every core at 5.0 Ghz, All the Time" :p thought I understand what he meant. Reply

    > almost everything uses AVX nowadays

    Did you mean "nothing"?
  • patrickjp93 - Sunday, May 26, 2019 - link

    No, he meant "everything". Your web browser uses it for compiling and interpreting javascript code, for example. The AVX data streaming instructions let you move data quickly between registers rather than load 64 bits one datem at a time from cache. Even games make extensive use of this rudimentary application of AVX. Reply

    Lol, wut?
