The AMD Threadripper PRO 7945WX is a desktop processor with 12 cores, launched in October 2023, at an MSRP of $1399. It is part of the Ryzen Threadripper lineup, using the Zen 4 (Storm Peak) architecture with Socket sTR5. Thanks to AMD Simultaneous Multithreading (SMT) the core-count is effectively doubled, to 24 threads. Threadripper PRO 7945WX has 64 MB of L3 cache and operates at 4.7 GHz by default, but can boost up to 5.3 GHz, depending on the workload. AMD is making the Threadripper PRO 7945WX on a 5 nm production node using 13,140 million transistors. The silicon die of the chip is not fabricated at AMD, but at the foundry of TSMC. You may freely adjust the unlocked multiplier on Threadripper PRO 7945WX, which simplifies overclocking greatly, as you can easily dial in any overclocking frequency.
With a TDP of 350 W, the Threadripper PRO 7945WX is extremely power hungry, which means you need top-notch cooling. AMD's processor supports DDR5 memory with an eight-channel interface. The highest officially supported memory speed is 5200 MT/s, but with overclocking (and the right memory modules) you can go even higher. ECC memory is supported, too, which is an important capability for mission-critical systems, to avoid data corruption. For communication with other components in the machine, Threadripper PRO 7945WX uses a PCI-Express Gen 5 connection. This processor does not have integrated graphics, you will need a separate graphics card.
Hardware virtualization is available on the Threadripper PRO 7945WX, which greatly improves virtual machine performance. Programs using Advanced Vector Extensions (AVX) can run on this processor, boosting performance for calculation-heavy applications. Besides AVX, AMD has added support for the newer AVX2 and AVX-512 instructions, too.
