As “usage” is subjective, I will consider any application / workload that offers a 35% ~ or higher performance improvement for the 32-core Threadripper 3970X.
Threadripper 3990x brings more CPU threads than Windows Pro can handle

On Friday, AMD launched its latest powerful processor – the 64-core, 128-thread Threadripper 3990x. The 3990x is not the first publicly available 128-thread x86-64 processor – this honor goes to the AMD Epyc 7742, 7702, and 7702P three-way processors. But the 3990X is the first “desktop” processor to offer so many threads – and thus stretches the ecosystem.
Cost per thread
Despite the groundbreaking TR3990x specs, AMD sticks to the same pricing strategy it has been using for years – choose a processor that suits your needs and pay for it a reasonable, roughly linear scaled price. If you want Threadripper threads, you’ll pay around $ 30 apiece for them, whether you’re looking for smaller or larger parts.
|Editor||Cores / threads||Cost||Cost per thread|
|AMD Threadripper 3990x||64/128||3990||$ 31.17|
|AMD Threadripper 3970x||32/64||400.999||$ 31.23|
|AMD Threadripper 3960x||24/48||400 399||29.15|
|AMD Epyc 7702P||64/128||4 784||37.36|
|Intel Xeon Platinum 9282||56/112||30,000 (?)||$ 267.86 (?)|
|Intel Core i9-10980XE||18/36||400,000||$ 27.78|
|Intel Core i9-9980XE||18/36||400 979||54.97|
This is in sharp contrast to Intel’s pricing strategies, which over the years have been tending to “pick a processor you can afford” rather than “choose a processor that suits your needs.” The prime example of this strategy is the top-of-the-line Intel Xeon Platinum series, which literally cannot be priced – they are not retailed – but can reasonably be estimated to cost about ten times more per thread than the closest competing Epyc parts.
However, we can see a major shift in Intel’s HEDT (High End DeskTop) pricing strategy since the introduction of the 3rd Gen Threadripper. Team Blue cut the price of its flagship HEDT part in half in one year. As a result, the cost of the top Core i9 part per thread was in line with – or even slightly cheaper – than competing Threadripper parts.
Back to Team Red, the 64-core Threadripper is a bit cheaper than the 64-core single-socket Epyc 7702P – but not enough to write about. This leaves the decision between building your system around the TR3990x or the 7702P, again, more focused on finding a build that fits your workflow rather than the cost that fits your wallet.
In our tests, the inclusion of PBO (Precision Boost Overdrive) resulted in a fairly high temperature rise. However, when working in a warehouse, it remains in a healthy area, even with a constant and full load.
