Intel Core i9-9900KS TDP Details: ASUS Maximus XI Apex Supportby Anton Shilov on September 18, 2019 9:30 AM EST

Intel announced plans to launch its eight-core Core i9-9900KS processor along with its performance specifications quite a while ago, but the company did not disclose the TDP. As the processor will have an all-core base frequency of 4.0 GHz and an all-core turbo of 5.0 GHz, this number is vitally important for motherboard support. This week ASUS released a new BIOS version for some of its motherboards that adds support for the Core i9-9900KS and revealed the number.
The Intel Core i9-9900 processor has a base frequency of 4.0 GHz as well as an all-core turbo frequency of 5.0 GHz, which essentially makes it an eight-core Coffee Lake Refresh silicon binned to hit higher clocks when cooling is good enough. As it turns out, in a bid to enable higher frequencies, Intel has increased the TDP all the way to 127 W (according to a listing at ASUS.com), which is considerably higher when compared to any existing (or historical) Intel’s CPU for mainstream platforms.
One thing that should be noted is that Intel only guarantees base frequency at a rated TDP (e.g., 4.0 GHz at 127 W), so everything above base (i.e., turbo clocks) means a higher power consumption. As a result, not only will the Core i9-9900KS require a motherboard that can supply 127 W of power and a cooling system that will dissipate 127 W of power, but it will need an advanced platform to hit the turbo clocks. Fortunately, there are plenty of high-end motherboards and coolers around to support the Core i9-9900KS.

|i9-9900KS||8 / 16||4.0 GHz||5.0 GHz||5.0 GHz||UHD 630||2666||127 W||?|
|i9-9900K||8 / 16||3.6 GHz||4.7 GHz||5.0 GHz||UHD 630||2666||95 W||$488|
|i9-9900KF||8 / 16||3.6 GHz||4.7 GHz||5.0 GHz||-||2666||95 W||$488|
|i7-9700K||8 / 8||3.6 GHz||4.6 GHz||4.9 GHz||UHD 630||2666||95 W||$374|
|i7-9700KF||8 / 8||3.6 GHz||4.6 GHz||4.9 GHz||-||2666||95 W||$374|
One thing to keep in mind is that the information about the TDP of the Core i9-9900KS comes from a third party (albeit a very reliable one), not from Intel. Intel has confirmed that the new Core i9-9900KS will be released in October.

bug77 - Wednesday, September 18, 2019 - linkFor the price difference, I can almost get another 8c/16t :D
AshlayW - Thursday, September 19, 2019 - linkThe difference between 5 GHz 9900K 1T and 4.4 GHz 3700X 1T is tiny. It is single digit percent. The former costs 75% more, consumer stupidity is why Intel still managed to command such a premium when it is now obvious they are the second-tir brand.
Flunk - Wednesday, September 18, 2019 - linkIntel's asleep at the wheel. If they weren't so desperate to ship every chip with half the space dedicated to an onboard GPU, they wouldn't have this problem. AMD's 16-core chip is smaller (even combining all modules) than Intel's 8-core.
Great_Scott - Wednesday, September 18, 2019 - linkIntel can come back from this. All they'd need to do is drop prices by 33% and they'd be the best option.
Of course, it's an open question whether Intel can actually profitably sell CPUs at those prices...
Gondalf - Wednesday, September 18, 2019 - linkBut yes 177 mm2 of 14nm silicon is very cheap today.
Korguz - Wednesday, September 18, 2019 - linkif 14nm is so cheap as you say.. then why does intel charge so much for its products ???
ilt24 - Wednesday, September 18, 2019 - link@Korguz ... "if 14nm is so cheap as you say.. then why does intel charge so much for its products"
Because they want to make a lot of profit.
Korguz - Wednesday, September 18, 2019 - linkyep.. thats why intel also makes you buy a new board after 2 or 3 years, if not sooner, cause their upgrade path sucks. X99 only lasted 2 cpus, before it was replaced...
edzieba - Thursday, September 19, 2019 - linkEvery Intel chipset was supported two generations of CPU ()and vice versa), since Sandy Bridge the better part of a decade ago. Pulling the "quelle surprise" act fools nobody.
As for Ryzen: while the idea to support more generations on AM4 is laudable, in practice the first-gen X300, A300 and A320 already do not support Zen 2 CPUs, and X570 does not support gen 1 CPUs. More than two generations support has already become a 'maybe' rather than a guarantee.
Karmena - Thursday, September 19, 2019 - linkB350, B450, X370, X470 and x570 do support all the generations. If you look those chipsets will be the majority of mobos sold. Also, A320 got support for 3rd gen CPUs however in the begging it was said that they will not do that. X300 chipset - was it even released as the intended use for ITX was taken by Xx70 chipset.
