The higher clock speeds of the Core i9-9900KS will lead to increased power consumption. The CPU will likely require high-end cooling and a premium motherboard.
Frankly, this was pretty obvious. Achieving an all-core 5000 MHz frequency on the outdated 14nm+ process, while maintaining a 95-watt package, is simply impossible. Even the regular 9900K struggled to stay within that limit and often consumed significantly more power.
Higher clock speeds inevitably lead to higher power consumption, and now we know the TDP for the as-yet-unreleased Core i9-9900KS.
ASUS recently updated information regarding the ROG Maximus XI APEX motherboard on its official website. It was on its CPU support page that the newcomer was spotted with an unprecedented TDP for LGA1151 processors:
⤢ ВІДКРИТИIt's hard to imagine how much power the Core i9-9900KS will draw in applications that heavily utilize AVX instructions, for example. Most likely, it will hit its thermal limits and throttle down to 4500-4700 MHz.
While this protection can certainly be disabled in the motherboard's BIOS settings, whether it's worth paying extra for a CPU that can't consistently maintain its advertised frequency is a subjective question.
These are all assumptions, of course. We'll need to wait for the processor's release and see in practice what all-core frequencies it can sustain under prolonged heavy loads.
However, we can already confidently state that future Core i9-9900KS owners will need serious liquid cooling to keep things quiet, along with a high-end motherboard featuring a robust power delivery system.
⤢ ВІДКРИТИThe price for the Core i9-9900KS hasn't been announced yet, but it's expected to fall in the $500–$600 range, especially considering the Core i9-9900K already sits between $488 and $500 in the US.
The processor is set to launch in October, and we'll be sure to provide more information on its thermal output and power consumption as soon as we have official data or independent test results.
