AMD has announced its first two third-generation Ryzen Threadripper processors: the Threadripper 3960X and the Threadripper 3970X. Both processors have higher clock speeds and more PCIe lanes than their second-generation predecessors and also PCIe version 4.0 support.

It will be possible to get your hands on the new chips on November 25th, when AMD announced that it will launch its flagship AM4 mainstream processor: the Ryzen 9 3950X with 16 cores and 32 threads.

The new TRX40 platform

Both new chips are made using AMD's 7 nm Zen 2 microarchitecture and have a total of 72 PCIe 4.0 lanes that can be used. They also use the new TRX40 platform and the sTRX4 socket, a change that AMD believes is necessary in part because of the number of PCIe lanes between the processor and the chipset that have doubled from 4 to 8.


The new Threadripper is followed by the Ryzen 3950X, which finally has a release date after being announced in June. This chip has the most cores and threads from the CPU line with AMD's mainstream AM4 sockets, but it also has the highest single-threaded performance, which according to AMD should make it the best processor to play. Sure, the 3950X's single-threaded performance is only 1 percent better than the Ryzen 3900X, but it has four additional cores.


In addition to a release date for the flagship AM4 chip, AMD also announced a new eco-mode feature for the processor, which allows a mode of execution at a lower power level and with lower energy consumption, preferring lower temperatures to higher performance. Along with the 3950X, AMD says echo mode will be available on all third-generation chips from Ryzen 5 onwards.


Finally, on the other end, AMD also announced a new cheap CPU from 49 dollars, AMD Athlon 3000G. Compared to the high end of the AMD range, the 2 cores and 4 threads of the chip look like a trifle, but AMD says the chip is unlocked and ready to be overclocked, squeezing a little more power with the right hardware. The new chip will be available on November 19th.
