The AMD Ryzen Threadrippers 2920X and 2970WX have been released for sale
AMD has put 2 more new Threadripper 2000-series models on sales. They are the 2920X and 2970WX processors. Like the flagship Ryzen 2 CPUs for this year, they both have 12 nm+ architecture. However, their 24-core/48-thread (for the 2950WX) and 12-core/24-thread (for the 2920X) 6-core structure may be a step down for some customers.
The 2920X and 2970WX have a TDP of 180W and 250W respectivevly, The 2920X has a base clock of 3.0GHz, and a boost clock, 4.3GHz, whereas the 2970WX runs from 3.5GHz to 4.2GHz. Both CPUs have 64 PCIe Gen3 Lanes. However, their most interesting aspect may be their prices: the 2920X goes for a recommended price of US$649, and the 2970WX is set at $1299. For context, this is about $500 less than the 2990WX and possibly $1000 less than a comparable Intel chip (which will have 18 cores).
The first reviews for the newly-released Threadrippers indicate that they can overclock stably (although this may be affected by the chipset lottery) and compete well with HEDT- and workstation-grade i9s well. The 2920X was found to outdo the i9-9900K, albeit in terms of multi-threaded performance only.
Similarly, the 2970WX outperformed the i9-7980XE in demanding tasks such as ray-tracing or rendering tests. However, its uneven memory architecture (by which 2 dies have no linked memory, and may thus falter when tasks bleed over to them) mean that shifts to more single-core work may cause the 2970WX to stutter. Therefore, the 2970WX may be a good deal for content-creation, but not much else.
