Intel Xeon E5-2650L 8-Core Processor vs AMD Ryzen Threadripper PRO 3975WX
These are not rivals. The Xeon E5-2650L is a 2012-era 8-core server chip on LGA2011; the Threadripper PRO 3975WX is a 32-core workstation part on sWRX8. Buy the Threadripper PRO if you need modern multi-core throughput, PCIe 4.0 and eight-channel memory. Buy the Xeon only to fill an existing LGA2011 board cheaply. The Threadripper PRO's lowest daily price was $547.95 as of November 3, 2026; no price was given for the Xeon.

Choose the Xeon E5-2650L if you already own a working LGA2011 board and need a low-power 70 W 8-core drop-in.
- 70 W TDP runs cool and quiet
- Cheap to buy used
- Fits existing LGA2011 servers and boards
- 20 MB L3 is decent for an 8-core of its generation

What reviewers say
AMD Ryzen Threadripper PRO 3975WX
Owner discussion of the 3975WX centers on its memory bandwidth and lane count for workstation work, and on the cost and heat of the platform around it. Most agree the chip itself is strong for rendering and virtualization; the complaints target the board, cooling and power budget.
- Memory bandwidthPraisedOwners value the eight-channel DDR4 setup for memory-hungry workloads.
- PCIe lanesPraisedThe 128 Gen 4 lanes are cited as the reason to pick this platform over mainstream CPUs.
- Power and heatCriticisedSustained all-core work draws close to the 280 W TDP and needs serious cooling.
Questions and answers
- Which is better for video rendering?
- The Threadripper PRO 3975WX. Its 32 cores, 64 threads and 128 MB L3 finish renders far faster than an 8-core 1.8 GHz Xeon.
- Is the Xeon E5-2650L still worth buying?
- Only as a cheap replacement in an existing LGA2011 system. As a new build it is far behind on clocks, memory and PCIe.
- Which uses less power?
- The Xeon at 70 W TDP versus 280 W for the Threadripper PRO. The Threadripper also needs a larger cooler and PSU.
- Does the Threadripper PRO support ECC memory?
- Yes. It supports registered ECC DDR4 across eight channels on sWRX8 boards.
- Can I put either chip in a normal desktop board?
- No. The Xeon needs LGA2011 and the Threadripper PRO needs sWRX8. Neither fits consumer sockets.
- Is the Threadripper PRO worth the extra cost?
- If you run parallel workloads, yes. At $547.95 as of November 3, 2026 it is a lot of cores for the money, but budget for the board and cooling.
