Quick Answers

So, is Xeon Gold 6240R better than Ryzen Threadripper PRO 3945WX?
It depends on what you want from the system. For gaming, Ryzen Threadripper PRO 3945WX is ahead with a 16.3% average FPS lead across 50 shared CPU game tests in our data. For rendering, compiling, streaming, and heavier multitasking, Xeon Gold 6240R pulls ahead with 21.6% better Cinebench R23 multi-core. Ryzen Threadripper PRO 3945WX also has the bigger cache pool with 79% larger total L3 cache (64 MB vs 36 MB).
Which one is better for streaming, content creation, and heavy multitasking?
For streaming, content creation, and heavier multitasking, Xeon Gold 6240R is the stronger fit. You are getting 21.6% better Cinebench R23 multi-core, backed by 24 cores and 48 threads.
Which one is the smarter buy today, not just the cheaper CPU?
Xeon Gold 6240R is still the faster CPU overall, but Ryzen Threadripper PRO 3945WX is easier to justify if budget matters more than peak performance. Xeon Gold 6240R comes in 112.7% more expensive on MSRP at $2,444 MSRP versus $1,149 MSRP, and it still gives you 21.6% better Cinebench R23 multi-core. The compromise is that Ryzen Threadripper PRO 3945WX is still the better pure gaming CPU with a 16.3% average FPS lead across 50 shared CPU game tests in our data. Ryzen Threadripper PRO 3945WX is also 113.4% better value on MSRP (29.1 vs 13.6 PassMark/$), which is why it can still make sense for tighter-budget builds on paper.
Which one is more future-proof for 2026 and beyond?
Xeon Gold 6240R makes more sense long term for 2026 and beyond. You are getting more multi-core headroom with 24 cores / 48 threads instead of 12/24 and AVX-512 support for heavier modern compute workloads. That extra compute headroom is more likely to matter as games, background tasks, and creator workloads get heavier.
