280W TDP?! That's more than what a large refrigerator uses ..
- gameswithgo 7y agoTDP does not reflect actual power draw. Actual power draw might be more, might be less. Either way, its like, eight normal computers.
- bitL 7y agoExpect max around 430W...
- bryanlarsen 7y agoAnandtech's testing showed full load power consumption of 279.82 W (3960X) and 286.72 W (3970X). OTOH the "255W" Xeon W-3175X full load power consumption was 381.08W...
- g4d 7y agoGoodness, I had no idea the power consumption of that Xeon was so high!
- bitL 7y ago2990WX with PBO enabled went over 400W.
- kllrnohj 7y agoOverclocking chips does tend to cause power usage to spike, yes. That's not exactly a new thing, nor is the increase that surprising. A slight bump to voltage will cause power consumption to skyrocket. Heck, i9-7980XE's at 4.9ghz are pushing 1kW in consumption. Hence why intel's 28 core @ 5ghz demo used a 1700W capable cooler.
- xbmcuser 7y agoah no Amd power numbers are usually on the money
- lazyjones 7y agoHow will they manage to package twice the cores at the same TDP? (3990X vs. 3970X, both apparently rated at 280W).
- wtallis 7y agoThe power consumption of an individual core can vary greatly depending on its clock speed (and voltage, which can be reduced when running at a lower clock speed). Putting 64 cores into the same TDP as their 32-core chip is actually pretty easy. If you actively use all 64 cores, they'll be running at a lower clock speed than if you were only using 32 cores.
- Zekio 7y agobinning the Chiplets helps them a ton with this
- geogra4 7y agoreminds me of how things were back in the days of the Pentium 4 Extreme Edition! EDIT: Wow, the TDP of that was only 115 watts[0]. I remember thinking it was just a monstrous power-sucker of a CPU. 0: https://ark.intel.com/content/www/us/en/ark/products/27492/pentium-4-processor-extreme-edition-supporting-ht-technology-3-73-ghz-2m-cache-1066-mhz-fsb.html https://ark.intel.com/content/www/us/en/ark/products/27492/p...
- gruez 7y ago>That's more than what a large refrigerator uses .. That's partially due to good insulation in modern fridges. After all, if the insulation is perfect, you could run a fridge on 0W (assuming you don't open the doors).
- all_blue_chucks 7y agoHow's that? By powering them with Maxwell's Demon? https://en.wikipedia.org/wiki/Maxwell%27s_demon https://en.wikipedia.org/wiki/Maxwell%27s_demon
- dsjimi 7y agoWatts are joules/second - with perfect insulation and doors not opening, the only energy used is the energy used to cool the contents initially. As time approaches infinity watts approach zero, despite the energy consumed initially. c/t -> 0 as t->INF given constant c.
- adtac 7y agoThen it's clear what must be done in the CPU world -- we need to insulate our CPUs better and eliminate all heat transfer.
