Intel’s next-generation Comet Lake CPUs will run hot and will require a lot of power

33 Comments

According to reports, Intel will officially reveal its next-generation Comet Lake CPUs on April 30th. And according to some early leaks, the high-end model, the Intel Core i9 10900-series, will require a lot of power and will run really hot.

HXL has shared the following images, showing the i9 10900F during a stress test. This CPU was running at 4.5Ghz on all ten cores and as we can clearly see, it hits 89 degrees of Celcium. And while Intel claims that this CPU may hit 5.3Ghz, it will obviously require the best CPU cooler solution in order to come close to that.

Not only that, but the i9 10900F has a PL1 rating of 170W and a PL2 rating of 224W. What this means is that the official TDP will be around 170W. However, and in order to sustain such overclocks on all cores, this CPU will require at times 224W.

Again, from what we know so far, Intel will officially reveal its Comet Lake CPUs on April 30th. The first benchmarks and reviews will also appear on April 30th. Lastly, the latest rumors suggest a late May release.

Stay tuned for more!

  1. Those power limits are frightening, but 89° really means nothing without knowing what cooler was used. An i7 8700 (non K), which is usually a pretty reasonable chip temp wise, can easily thermal throttle on Intel’s crappy stock cooler.

      1. Not compared to something like a 3600, but if you use even the cheapest, crappiest aftermarket air cooler on the 8700, the temps are more than reasonable. My point being that 89° temp for the 10900F means nothing unless we know the cooler used.

        1. No i wasn’t comparing it to anything, i was just talking about tests i saw back at its launch and right after it.

          1. Hardware Unboxed did extensive testing, and found that a $10-$20 air cooler is more than enough to keep the i7 8700 from thermal throttling. This link goes to the relevant timestamp, but it’s an interesting video that’s worth watching all the way through.

          2. >Hardware unboxed

            Besides he might’ve been lucky with his sample, 8700/K is not a reasonable chip temp wise, it’s probably one of the worst recent CPUs in that regard.

            Yes, one of the best hardware reviewers in the industry. And WTF are you talking about with golden sample? It’s a locked part.

          5. Lmao one of the worst maybe, and it’s not like silicon lottery is only about overclocking, you think every 8700 you buy is going to have the exact same temps? Due to the thermal compound used under the ihs, which isn’t soldered unlike series 9000 or older intel CPUs, temps are not consistent

    2. those power limits are not frightening. They are essentially in line with any 8xxx/9xxx CPU you overclock to exactly those values yourself. It’s just all that intel did was take an 8xxx tech and set the lower limit to over 4 GHz instead of 3-something as it was the case before. Push those to 4.8-5GHz and they do well over 200W.

  3. I just bought an AMD Ryzen 9 3900X (12C/24T), Gigabyte Aorus Master mobo, RTX2080 Super. (finally upgrading my FX8350 + GTX970 combo)

      1. Yeah man, but I’m going the 4k route soon (I know that 2080 Super won’t be enough tho), I like to play on big screens and put my eye in a 55″ 4k TV LG C9 OLED 120hz (around 1400€).
        I saved for 5 months to buy a 2700€ PC (including the case Phanteks Enthoo Evolv X, NVMe SSD Crucial P1, a 2TB Crucial MX500 SSD, liquid cooler Fractal Design Celsius S36, 32GB RAM Kingston Hyper X, a 850W Cooler Master PSU).
        I’m a happy guy for sure. That TV will be at least another 2 to 3 month of saves, but I got used to big screens since I play on a 47″ HDTV Sharp Aquos since 2009, can’t stand monitors anymore just because of the size.

        Thanks for the good vibes. 😉

        PS: That TV has G-Sync, and if I play in a lower resolution, the upscale is still amazing and I’ll have 120Hz. hehe

  6. Intel instead of innovating tries to win a battle with brute force and huge power supply behind it, just to have that nr1 spot.

    1. Nope. They just try to stay relevant as they fall over themselves trying to catch up. They were seriously planning to release a 10 nm CPU last or this year but AMD going 7 nm made that obsolete before it even happened. So they are in a full panic mode trying to get to 7 nm themselves.

  7. Wonder which coolers can run it. 95TDP i7 8086k already hits to 60-70 with 360 AIO non overclocked. Even slight overclock will push it to near 90s and overheating if ran with heavy stress test

    1. that must be a pretty bad AIO setup you have. My 9600K (which is about the same, bar hyperthreading) running at 4.8 GHz on all cores gets to 82C in summertime tops on a Noctua air cooler.

      1. It lacks hyperthreading which increases heat output a ton. And 8gen CPUs have toothpaste inside ISH unlike yours which is soldered

  9. “Not only that, but the i9 10900F has a PL1 rating of 170W and a PL2 rating of 224W. What this means is that the official TDP will be around 170W.”

    Holy crap. Ya, no thanks.

    1. still won’t help. Sadly laptops just lack the space needed for proper cooling, especially nowadays when everybody goes after as thin as possible.

  13. Base cooler: 420mm aio, optimal cooling: custom 560mm or better with very thicC radiators, super fast amd powerfull pump.
