Our take on the AMD Ryzen Threadripper Pro 3945WX

The AMD Ryzen Threadripper Pro 3945WX is a 12-core, 24-thread workstation processor built on the Zen 2 architecture. It runs at a 4.0 GHz base clock with 4.3 GHz boost, and it sits on the WRX80 platform with 128 PCIe 4.0 lanes and 8-channel memory support. That platform is what separates it from mainstream desktop chips: it suits people running CAD, simulation, rendering and multi-GPU work who need lanes and memory bandwidth more than the highest clock speeds. Against newer Threadripper Pro 5000 and 7000 parts it is older silicon with lower per-core performance, so it makes sense mainly for buyers already on WRX80 or picking one up cheaply.

Best forWorkstation builders on the WRX80 platformCAD, simulation and rendering workloadsMulti-GPU and high-lane-count setupsUsers who need 8-channel memory capacity
Pros
  • 12 cores and 24 threads handle heavy multithreaded work
  • 128 PCIe 4.0 lanes for GPUs, storage and add-in cards
  • 8-channel DDR4 memory support for large datasets
  • 4.0 GHz base clock is high for a workstation chip
  • Unlocked for overclocking on WRX80 boards
Cons
  • Zen 2 cores trail newer Threadripper Pro generations
  • High power draw and heat under sustained load
  • WRX80 motherboards and cooling add significant cost
  • Needs a dedicated large socket and cooler
  • No integrated graphics

What reviewers say

Owner discussion of the 3945WX is thin, but workstation users generally treat it as a solid lane-and-memory platform chip rather than a speed leader. Most commentary compares it unfavorably on per-core performance with newer Threadripper Pro models.

What people mention
  • PerformanceMixedOwners find multithreaded throughput strong but per-core speed behind newer Threadripper Pro chips.
  • PCIe lanesPraisedThe 128 PCIe 4.0 lanes are the main reason buyers choose this platform.
  • Power and heatCriticisedSustained loads draw heavy power and need serious cooling.
  • Platform costCriticisedWRX80 boards and coolers make the total build expensive for the performance.
  • MemoryPraised8-channel DDR4 support is valued for large datasets and memory-hungry applications.

Questions and answers

Is the 3945WX worth it over a mainstream desktop CPU?
Only if you need many PCIe lanes or 8-channel memory. For plain gaming or office work, a mainstream Ryzen or Core chip gives more performance for less.
How does it compare with the Threadripper Pro 3955WX?
The 3955WX has 16 cores and 32 threads on the same platform. The 3945WX trades cores for a higher 4.0 GHz base clock, so it favors lightly threaded work.
What motherboard does it need?
It uses the sWRX8 socket and requires a WRX80 chipset motherboard. It will not fit TRX40 or standard AM4 boards.
Does it support overclocking?
Yes, it is unlocked, and WRX80 boards allow overclocking. Gains are modest and heat rises quickly, so good cooling is required.
Does it have integrated graphics?
No. You need a discrete graphics card to get display output.
What memory does it support?
It supports 8-channel DDR4 memory, which is the main reason to choose this platform over mainstream desktop parts.
Where is the AMD Ryzen Threadripper Pro 3945WX cheapest?
At InpexOpcion, for $191.00, as of our latest check.
