AMD Ryzen Threadripper

The AMD Threadripper series bundles the currently fastest AMD processors and is only available for the desktop area. Technically, the AMD Threadripper processors are similar to AMD's EPYC series server processors, but the memory interface has been halved compared to the server processors. The AMD Threadripper processors support 4 memory channels (quad-channel) and a maximum amount of 2 TB of RAM. DDR4-3200 RAM is supported as a maximum, the maximum bandwidth when using all four memory channels is over 102 GB/s and thus twice as high as with the current AMD Ryzen processors.

The AMD Threadripper processors are also better positioned in terms of interface support than the AMD Ryzen CPUs, which were developed for the mainstream area. AMD's Threadripper CPUs support up to 72 PCIe 4.0 lines and can thus connect multiple graphics cards and fast M.2 SSDs to the system with maximum bandwidth.

Although the core architecture of the AMD Threadripper processors is based on that of the AMD Ryzen processors, up to 4 internal chips are combined here (with AMD Ryzen 9 a maximum of 2). A maximum of up to 64 CPU cores and 128 simultaneous threads are currently possible in the AMD Threadripper processors. Due to the many CPU cores, the clock frequency is a maximum of 4.3 GHz (single-core turbo) and thus slightly lower than the fastest AMD Ryzen 9 processors, which clock at up to 4.9 GHz.

Due to the many CPU cores, the Threadripper CPUs also need a lot of energy. Up to 280 watts TDP are possible, the processors are supplied with the necessary energy via the TRX4 socket. The 64-core CPUs can access up to 256 MB level 3 cache. The AMD Threadripper processors do not have internal graphics. Likewise, there are no mobile processors in the series.
