Quick Answers

So, is Xeon 6737P better than Ryzen Threadripper 3990X?

It depends on what you want from the system. For gaming, Ryzen Threadripper 3990X is ahead with a 12.4% average FPS lead across 50 shared CPU game tests in our data. For rendering, compiling, streaming, and heavier multitasking, Xeon 6737P pulls ahead with 104.1% better Geekbench multi-core. Ryzen Threadripper 3990X also has the bigger cache pool with 77.8% larger total L3 cache (256 MB vs 144 MB).

Which one is better for streaming, content creation, and heavy multitasking?

For streaming, content creation, and heavier multitasking, Xeon 6737P is the stronger fit. You are getting 104.1% better Geekbench multi-core, backed by 32 cores and 64 threads.

Which one is the smarter buy today, not just the cheaper CPU?

Xeon 6737P is still the faster CPU overall, but Ryzen Threadripper 3990X is easier to justify if budget matters more than peak performance. Xeon 6737P comes in 25.2% more expensive on MSRP at $4,995 MSRP versus $3,990 MSRP, and it still gives you 104.1% better Geekbench multi-core. The compromise is that Ryzen Threadripper 3990X is still the better pure gaming CPU with a 12.4% average FPS lead across 50 shared CPU game tests in our data. Ryzen Threadripper 3990X is also 25.6% better value on MSRP (20.0 vs 15.9 PassMark/$), 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 6737P makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2025 vs 2019), a healthier platform with LGA4710 and DDR5 instead of TR4, more multi-core headroom with 32 cores / 64 threads instead of 64/128, and AVX-512 support for heavier modern compute workloads. That gives you a healthier platform runway for motherboard, RAM, and later CPU upgrades.
