Quick Answers

So, is Ryzen 9 5900X better than Xeon 6737P?

Not in a simple one-size-fits-all way. Xeon 6737P makes more sense for workstation-style multi-core throughput, while Ryzen 9 5900X is the better mainstream desktop choice for gaming, platform cost, and day-to-day practicality.

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

For streaming, content creation, and heavier multitasking, Xeon 6737P is the better fit. You are getting 278.5% better Geekbench multi-core, backed by 32 cores and 64 threads. It also carries the larger cache pool with 125% larger total L3 cache (144 MB vs 64 MB).

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

Ryzen 9 5900X is the smarter buy today. Ryzen 9 5900X is $4,446 cheaper on MSRP at $549 MSRP versus $4,995 MSRP, and it gives you a 27.7% average FPS lead across 50 shared CPU game tests in our data. The trade-off is that Xeon 6737P is still stronger for heavier multi-core work with 278.5% better Geekbench multi-core. It is also 345.1% better value on MSRP (71.0 vs 15.9 PassMark/$), so the better CPU is not just faster, it is also the cleaner value play on paper.

Which one is more future-proof for 2026 and beyond?

Xeon 6737P is the more future-proof choice for 2026 and beyond. You are getting a newer CPU generation (2025 vs 2020), a healthier platform with LGA4710 and DDR5 instead of AM4, 125% larger total L3 cache (144 MB vs 64 MB), more multi-core headroom with 32 cores / 64 threads instead of 12/24, and AVX-512 support for heavier modern compute workloads. That should give you a better long-term upgrade path for motherboard, RAM, and future CPU swaps.
