The AMD third-generation thread tearer processor Threadripper 3970X has a thermal design of 280W, but AMD actually offers 180W, 140W, or even 95W TDP gears for user debugging options for better energy efficiency. Germany’s CB recently examined in detail how much the 3970X would lose in performance if it pulled the wall.
Tests showthat that at 180W TDP, the 3970X’s main frequency is reduced to 3.37GHz, i.e. 35% less power consumption and 10% reduction in the main frequency. Interestingly, however, even then, its multithreaded performance is still better than the blood-soaked 3960X (24 cores).
Moreover, in the 140W state, the 3970X’s multicore application performance remains before intel i9-10980XE, which has 165W, 18-core 32 threads.
As for single-core performance, the 3970X is flat with the i9-10980XE even if it is reduced to a 95W hypereconomy model.
If you’re still stuck in the stereotype of three years ago that AMD is hot, power-hungry, and low-performance, it’s a shame.
