TDP 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.
