Quick Answers

So, is Ryzen 7 8745HX better than Ryzen Threadripper PRO 3945WX?

Not really, because they are built for different jobs. Ryzen Threadripper PRO 3945WX makes more sense for workstation-style multi-core throughput, while Ryzen 7 8745HX is the more practical desktop choice for gaming, platform cost, and everyday use.

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

For streaming, content creation, and heavier multitasking, Ryzen Threadripper PRO 3945WX is the stronger fit. You are getting 2.8% better Cinebench R23 multi-core, backed by 12 cores and 24 threads. It also has the larger cache pool with 100% larger total L3 cache (64 MB vs 32 MB).

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 is easier to justify if budget matters more than peak performance. Ryzen 7 8745HX comes in at an unclear MSRP at unclear MSRP versus $1,149 MSRP, and it still gives you a 2.1% average FPS lead across 50 shared CPU game tests in our data. The compromise is that Ryzen Threadripper PRO 3945WX is still stronger for heavier multi-core work with 2.8% better Cinebench R23 multi-core. Ryzen Threadripper PRO 3945WX is also 100.0% better value on MSRP (29.1 vs 0.0 PassMark/$), which is why it can still make sense for tighter-budget builds on paper.

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

Ryzen 7 8745HX makes more sense long term 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 gives you a healthier platform runway for motherboard, RAM, and later CPU upgrades.
