Ryzen 7000 Rumored to run very Hot

270w and just 82oC? I find this hard to believe when 12900k at 241w can reach 100c (in CB23) with the best air cooling and around 93c with average priced AIO..

Higher numbers, more faster though :P

I know what will happen next. Suddenly AMD fanboys will no longer care that CPUs are running hot, it will become "fine" and "norm" 😀

Just like it is normal for top-end Intel owners! 🙂

to be expected, high frequency and very high transistor density. In the future I suspect that direct die or full encasement will become unavoidable, unless the power consumption can be drastically improved through some other means than just making the transistors smaller.

Nobody is going to see these kinds of temps or power draws outside of a benchmark unless they're doing renders all day long (on either platform).

4790K ran hot? When running it stock with a dual 120 rad I didn't see it get near the max temperatures of my current CPU @ stock with a triple 120 rad.

My 4690k with undervolting ran stupid hot with 120mm rad even de-lidding it didn't help too much it was a bad design choice removing the solder to be more greedy

Yep, it was bad. It was the first gen where they started using TIM. I replaced the TIM with liquid metal and dropped ~20C iirc. After that I found I was able to reduce vcore from stock while bumping up the speed to 4.7ghz. Prior to that overclocking was a complete no go with the cooler I had.

Or some avx test and since this new zen4 is 512avx capable, it could be where most heat and wattage comes from.

Meh TDP is now a meaningless number the real number we need is the total power draw at max all core speed

I don't think that avx 512 will make much difference to the power consumption, unlike intel which has full 512 width simd units on their chips, amd isn't doing that , they are opting to keep it at 256bit like avx2, presumably they do 512bit instructions broken up into 2 256bit ops instead, the amd presentation claimed that this was done because the loss of frequency with 512 bit wide units can be pretty severe, so "double pumping" a 256bit design allows them to keep the frequency higher. While amd will support the instruction, its probably not going to offer the same level of gains seen on intel chips with software that benefits from it.

With a nickname like that, of course it "grabs your attention". Aka, you perfectly know this isn't a stock configuration for 13900K, just trying to make sensationalist post. Any CPU can do crazy wattage when you overclock, overvolt, etc. etc.

UMMM ok? https://media1.giphy.com/media/HIzPcMOuWfEyY/200.gif?cid=ecf05e47ypxgebudr2vdzgm8l23yghrvf4ntzo4gi6g2mjvz&rid=200.gif&ct=g

Up Til September 2017 i was strictly AMD processor user, knew nothing on CPU Cooling that much, used the Stock Intel Cooler for 4 years on my I7 7700 i had then. Updated in June 2020 to Intel 10700, went with what Shop used at the time when built this PC, Stock CPU Cooler til May 2022, and decided to upgrade to a bigger a bit Tower Cooler, Originally wanted to go with Be Quiet Pure Rock 2 Black, but had issues installing it, so Plan B lugged it to PC shop, and went with whatever Air Cooler was in stock. Arctic Freezer 7X Cools much better than the Stock Air Cooler did, so i'm pretty happy at this point.
