Ryzen 5 8645HS vs Xeon W-2255: 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 165W, a 120W reduction.
✅Newer platform on FP8 with DDR5 support instead of LGA2066 and DDR4.
✅100+% more PCIe lanes (20 vs 0) for storage and expansion-heavy builds.
✅Integrated graphics onboard with Radeon 760M, while Xeon W-2255 needs a discrete GPU.

Trade-offs

❌Lower PassMark (22,257 vs 22,504).
❌Smaller total L3 cache (16 MB vs 19 MB).
❌Less compelling for workstation-style loads than Xeon W-2255, which brings 10 cores / 20 threads.

Xeon W-2255

2019

Why buy it

✅+1.1% higher PassMark.
✅+20.3% larger total L3 cache (19 MB vs 16 MB).
✅Better for workstations and heavier parallel workloads: 10 cores / 20 threads.

Trade-offs

❌Launch MSRP is still $778 MSRP, while Ryzen 5 8645HS mostly shows up through inconsistent older-market listings.
❌266.7% higher power demand at 165W vs 45W.
❌Older platform position on LGA2066 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 Ryzen 5 8645HS better than Xeon W-2255?

Not really, because they are built for different jobs. Xeon W-2255 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 streaming, content creation, and heavy multitasking?

For streaming, content creation, and heavier multitasking, Xeon W-2255 is the stronger fit. You are getting 1.1% better PassMark, backed by 10 cores and 20 threads. It also has the larger cache pool with 20.3% larger total L3 cache (19 MB vs 16 MB).

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

Ryzen 5 8645HS is still the faster CPU overall, but Xeon W-2255 is easier to justify if budget matters more than peak performance. Ryzen 5 8645HS comes in at an unclear MSRP at unclear MSRP versus $778 MSRP, and it still gives you a 0.5% average FPS lead across 50 shared CPU game tests in our data. The compromise is that Xeon W-2255 is still stronger for heavier multi-core work with 1.1% better PassMark. Xeon W-2255 is also 100.0% better value on MSRP (28.9 vs 0.0 PassMark/$), 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 5 8645HS makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2023 vs 2019), a healthier platform with FP8 and DDR5 instead of LGA2066, and AVX-512 support for heavier modern compute workloads. That gives you a healthier platform runway for motherboard, RAM, and later CPU upgrades.
