Quick Answers

So, is Ryzen 9 8945HS better than Core i9-9980XE?

It depends on what you want from the system. For gaming, Ryzen 9 8945HS is ahead with a 22.3% average FPS lead across 50 shared CPU game tests in our data. For rendering, compiling, streaming, and heavier multitasking, Core i9-9980XE pulls ahead with 27.9% better Cinebench R23 multi-core. Core i9-9980XE also has the bigger cache pool with 54.7% larger total L3 cache (25 MB vs 16 MB).

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

For streaming, content creation, and heavier multitasking, Core i9-9980XE is the stronger fit. You are getting 27.9% better Cinebench R23 multi-core, backed by 18 cores and 36 threads. It also has the larger cache pool with 54.7% larger total L3 cache (25 MB vs 16 MB).

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

Ryzen 9 8945HS is still the much better call for a fresh build. Ryzen 9 8945HS comes in at an unclear MSRP at unclear MSRP versus $1,979 MSRP, and it still gives you a 22.3% average FPS lead across 50 shared CPU game tests in our data. Core i9-9980XE only looks stronger on raw value math because it is extremely cheap, but that usually means used-market pricing on an obsolete 2018 platform. Even with 100.0% better value on paper (14.7 vs 0.0 PassMark/$), it really only makes sense as a cheap stopgap or a niche existing-platform option for someone already on LGA2066.

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

Ryzen 9 8945HS makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2023 vs 2018) and a healthier platform with FP8 and DDR5 instead of LGA2066. That gives you a healthier platform runway for motherboard, RAM, and later CPU upgrades.
