AMD has introduced two new third-generation top-of-the-line models, Threadripper 3000 CPUs based on AMD&s 7nm "Zen 2" architecture together with the new sTRX4 socket, which are the fastest desktop processors available on the market. Together with the new TRX40 platform with 72 PCIe 4.0 lanes, they target professional applications such as video editing or 3D modeling that require maximum performance.
The new models Ryzen Threadripper 3960X with 24 CPU cores (48 threads) and 3970X with 32 cores (64 threads) have a basic clock rate of 3.8 GHz (3960X : 3.7GHz), which corresponds to a significant increase in the clock rate (and thus the speed) of 800 and 700 MHz (3970X) respectively compared to the predecessor models Ryzen Threadripper 2990WX and 2970WX. The maximum turbo clock was slightly increased by 300 MHz to 4.5 GHz. The performance should be 40-60 percent higher than the predecessors on average, ideally even up to 80%. The new processors have up to 88 (72 of them usable) PCIe lanes and 144 MB cache (3960X : 140 MB) - the TDP stereizes from 250 to 280 watts.

Interesting for editors: according to the AMD press release, the 32-core 3970X Threadripper delivers 47% more performance in Adobe Premiere as well as an impressive 90% increase in Cinebench score compared to the similarly expensive 18-core Intel Core i9-9980XE.
The new Threadripper 3000 CPUs cannot be used on an old X399 motherboard, they need a new TRX40 motherboard with sTRX4 socket, which is supposed to scale better according to AMD - according to rumours AMD will introduce a 64-core Ryzen Threadripper 3990X at a later time.
The change from PCIe 3.0 to version 4.0, which results in a doubling of the PCIe bandwidth per lane, guarantees a big jump in performance. Further improvements of the new platform include several important points: there are four additional PCIe 4.0 lanes as well as a doubling of the four PCIe lanes for communication between chipset and CPU to eight, thereby and by using PCIe 4.0 the transfer rate quadruples to 16 GB/s.
A total of 72 PCIe lanes are available on a TRX40 motherboard (56 per Threadripper 3000 plus 16 per TRX40 chipset), the motherboard manufacturers then decide on the exact distribution. Eight lanes can be used for mass storage (e.g. two x4 NVMe SSDs or eight SATA 6G ports). Up to 48 PCIe 4.0 lanes can be used for graphics cards, which can be used to connect three GPUs in the form of three x16 slots, for example. A further 16 PCIe 4.0 lanes are available, e.g. in the form of twelve SATA ports as well as four USB 2.0 and eight fast USB 3.2 Gen2 ports. Four additional USB 3.2 Gen2 ports are directly connected to the processor.
Several manufacturers (ASRock, Asus, Gigabyte and MSI) have already introduced TRX40 mainboards which use the numerous PCIe 4.0 lanes and thus offer a rich selection of interfaces: 3-4 PCIe 4.0 x16 slots, several M.2 and USB 3.2 Gen2x2 ports (with 20 Gigabit/s) as well as 10-Gigabit-LAN.
Market launch for the new processors and matching motherboards is November 25th - the 3960X will cost around 1,400, the 3970X around 1,800, the motherboards will be slightly more expensive than their X399 counterparts.
