Ryzen 5 8645HS vs Xeon W-1290P: Pros, Cons & Final Verdict

See where each CPU makes more sense in practice: gaming, heavier work, platform cost, power draw, and upgrade path.

Ryzen 5 8645HS

2023

Why buy it

✅Draws 45W instead of 125W, a 80W reduction.
✅Newer platform on FP8 with DDR5 support instead of LGA1200 and DDR4.
✅100+% more PCIe lanes (20 vs 0) for storage and expansion-heavy builds.
✅Integrated graphics onboard with Radeon 760M, while Xeon W-1290P needs a discrete GPU.

Trade-offs

❌Lower PassMark (22,257 vs 22,373).
❌Smaller total L3 cache (16 MB vs 20 MB).
❌Less compelling for workstation-style loads than Xeon W-1290P, which brings 10 cores / 20 threads.

Xeon W-1290P

2020

Why buy it

✅+25% larger total L3 cache (20 MB vs 16 MB).
✅Better for workstations and heavier parallel workloads: 10 cores / 20 threads.

Trade-offs

❌177.8% higher power demand at 125W vs 45W.
❌Older platform position on LGA1200 with DDR4, while Ryzen 5 8645HS moves to FP8 and DDR5.
❌No integrated graphics, while Ryzen 5 8645HS can still boot and troubleshoot without a discrete GPU.

Quick Answers

So, is Xeon W-1290P better than Ryzen 5 8645HS?

Not really, because they are built for different jobs. Xeon W-1290P makes more sense for workstation-style multi-core throughput, while Ryzen 5 8645HS is the more practical desktop choice for gaming, platform cost, and everyday use.

Which one is better for gaming?

If gaming is the priority, Xeon W-1290P is the better pick. According to our tests, it delivers 2.2% more average FPS across 50 shared CPU game tests.

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

For streaming, content creation, and heavier multitasking, Xeon W-1290P is the stronger fit. You are getting 0.5% better PassMark, backed by 10 cores and 20 threads. It also has the larger cache pool with 25% larger total L3 cache (20 MB vs 16 MB).

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

Xeon W-1290P still makes the most sense overall. Xeon W-1290P comes in at an unclear MSRP at unclear MSRP versus unclear MSRP, and it still gives you a 2.2% average FPS lead across 50 shared CPU game tests in our data.

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

Ryzen 5 8645HS makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2023 vs 2020), a healthier platform with FP8 and DDR5 instead of LGA1200, and AVX-512 support for heavier modern compute workloads. That gives you a healthier platform runway for motherboard, RAM, and later CPU upgrades.
