What is the Threadripper Pro 5945WX good at?

It is a 12-core, 24-thread professional CPU with a 4.1 GHz base clock. It handles multi-threaded rendering, simulation and CAD work well, and its 128 PCIe 4.0 lanes support multiple GPUs and fast storage.

How does the P620 compare with a dual-socket Xeon workstation?

The P620 uses one Threadripper Pro socket instead of two Xeon sockets. That means fewer parts, lower noise and simpler memory population, while still offering high core counts and 8-channel memory.

Can I upgrade the CPU later?

The P620 uses the sWRX8 socket for Threadripper Pro chips. Upgrades are limited to that platform and depend on Lenovo's supported CPU list and BIOS, so check compatibility before buying a replacement part.

Is it good for gaming?

It can run games, but the P620 is tuned for professional workloads. A consumer desktop with a faster gaming GPU generally gives better frame rates for less.

What kind of memory does it use?

Threadripper Pro supports 8-channel DDR4 ECC memory. ECC is useful for long simulations and data work where memory errors are costly.

Who should not buy it?

Shoppers who mainly browse, write documents or play games will not use its cores or PCIe lanes. A mainstream desktop is smaller, quieter and better value for those tasks.
