Now that the new Ryzen 3000 CPUs have been released with many reviews showing their performance over previous generations, it is time for the leaks and rumours about the Ryzen Threadripper 3000 series to begin.

A UserBenchmark result spotted by twitter user TUM_APISAK who is famous for his leaks.

The UserBenchmark result is for a 16-core, 32-thread engineering sample, appearing to be a codename ‘Castle Peak’ part. This would likely be an early version of what would have been the AMD Ryzen 3950X, however that name is taken so the best guess at the moment is 3950WX. The chip is running at a base clock of 3.6 GHz along with a boost clock of 4.0 GHz running on AMD’s SP3v2 socket with a quad-channel memory configuration.

When compared against the Ryzen Threadripper 2950X, the Castle Peak engineering sample has a 100 MHz higher base clock, but a 400 MHz lower base clock.  As this is an engineering sample, the clocks will not be final. This engineering sample has more L3 cache, just like other Zen 2 processors.

Compared to Ryzen Threadripper 2950X, the new Castle Peak chip results in an overall performance uplift of 11%. In the single-core and quad-core fields 11% faster than the Ryzen Threadripper 2950X, and 18% faster when comparing multi-core performance.

It does, however, only perform on par with the Ryzen 9 3900X in single and quad-core but and leads by 36% in multi-core performance (2061 vs 2811) which is to be expected due to its higher core count.

Not a great deal is known about the new Ryzen 3rd Generation Threadripper. At the moment we know that 64-cores are possible with Zen 2 on AMD’s SP3 EPYC socket, which means that up to 64-core designs are also possible on TR4. With the 3950X doubling the number of cores available on the consumer range it is almost guaranteed we will see another big increase in cores on Threadripper, with it potentially going all the way up to 64-cores.

Unlike AMD’s existing Threadripper processors, Ryzen 3rd Generation/Zen 2 Threadripper will utilise a single, unified memory controller on a separate I/O/memory die. This is similar to what AMD has shown with their Zen 2 EPYC processors. With 3rd Gen Threadripper, AMD can deliver a true quad-channel memory setup with identical memory access latencies to all CPU cores. This is impossible on AMD’s previous multi-memory controller solution.

Ryzen Threadripper 3000 will be built on the 7nm FinFET process by TSMC and will bring new features to AMD’s HEDT platform such as PCIe 4.0. Whether or not AMD plans on releasing a successor to X399 is unknown, and if they do the combination of PCIe 4.0 and the premium prices of X399 will likely set new levels of pricing for motherboards which is already very steep with the £700+ Gigabyte AMD Ryzen X570 AORUS XTREME.
