TDP are made up numbers. Since they are arbitrary, you can't meaningfully say that they have doubled.

- wmf 4y agoIt's not that made up. 5950X used 120-140 W and I expect the 7950X to use 210-230 W. AMD said that the increased multicore performance comes from a higher power limit.
- db48x 4y agoI’ve no doubt that the newer cpu will use more power, but the numbers are made up. They’re picked by the marketing department using a formula, and calling them “watts” to try to make them look like energy used or heat dissipated doesn’t make them real. They don’t correspond to numbers that you can actually measure in any way.
- joshvm 4y agoWhether or not what marketing calls it is accurate, Anandtech measure power draw in their reviews and (at least in this example) it's pretty well aligned with the advertised TDP/PPT: https://www.anandtech.com/show/15043/the-amd-ryzen-9-3950x-review-16-cores-on-7nm-with-pcie-40/2 https://www.anandtech.com/show/15043/the-amd-ryzen-9-3950x-r...
- trashtester 4y agoThe 105W for the 3950X doesn't include package power. Add that, and it's closer to 150W (at least for me). This is before enabling PBO.
- db48x 4y agoThey measured one “105W” TDP chip maxing out at 86 Watts, and another “105W” TDP chip maxing out at 144 Watts? That’s not “pretty well aligned” with anything.
