The reported TDP is the designed TDP for the motherboard power delivery, not the measured consumption of each processor. To keep the number of TDP values low and to allow motherboard makers design a small number of variants, TDP values are rounded up to 65W, 95W and 105W. That means everything that goes above 65W in real life will be classified as 95W, even if the real consumption is 70 or 75W.
- rasz 7y agoNot really. Intel made TDP numbers meaningless long time ago, AMD finally joined Intel with Zen2. While Zen1 180W TDP Threadrippers actually did consume 180W from the power supply, Zen2 take x1.5 the rated power similar to intel counterparts like "95W" 9900K consuming 150-200W.
- makomk 7y agoActual power cap for Zen2 seems to be 1.35x TDP, but the speculation about them choosing a small number of TDP categories and sticking all their processors into them sounds right aside from that.
- nottorp 7y agoActually I think the anandtech page says that the 65W part consumes 90W at full load? Or so I read their graphs on the power consumption part...
