Which one is the smarter buy today, not just the cheaper CPU?
Ryzen 7 8745HX is still the faster CPU overall, but Ryzen Threadripper PRO 3945WX makes more sense if price matters more than absolute performance. Ryzen 7 8745HX is at an unclear MSRP at unclear MSRP versus $1,149 MSRP, and it gives you a 9.5% average FPS lead across 3 shared CPU game tests in our data. The trade-off is that Ryzen Threadripper PRO 3945WX is still stronger for heavier multi-core work with 2.8% better Cinebench R23 multi-core. Ryzen Threadripper PRO 3945WX is also 100.0% better value on MSRP (29.1 vs 0.0 PassMark/$), which is why it is easier to justify for price-conscious builds on paper.
Which one is more future-proof for 2026 and beyond?
Ryzen 7 8745HX is the more future-proof choice for 2026 and beyond. You are getting a newer CPU generation (2025 vs 2020), a healthier platform with FL1 and DDR5 instead of sWRX8, 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.

Games Benchmarks

Paired with RTX 4090

To accurately isolate CPU performance, all benchmarks below use an NVIDIA RTX 4090 as the reference GPU. This eliminates GPU-side bottlenecks and highlights pure processing throughput differences between the CPUs.

Note: Real-world results may vary based on your actual GPU. CPU performance impact is more visible in processing-intensive titles and high-refresh-rate gaming scenarios.
