Quick Answers

So, is Xeon W-10855M better than Xeon D-2143IT?

Yes. Xeon W-10855M is the better all-around CPU here. It gives you a 16.4% average FPS lead across 50 shared CPU game tests in our data, 1.1% better PassMark, and the stronger long-term platform, which is enough to make it the stronger overall pick.

Which one is better for gaming?

If gaming is the priority, Xeon W-10855M is the better pick. According to our tests, it delivers 16.4% 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-10855M is the stronger fit. You are getting 1.1% better PassMark, backed by 6 cores and 12 threads.

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

Xeon W-10855M is the better buy right now. Xeon W-10855M comes in at an unclear MSRP at $118 MSRP versus unclear MSRP, and it still gives you a 16.4% average FPS lead across 50 shared CPU game tests in our data. It is also 100.0% better value on MSRP (103.8 vs 0.0 PassMark/$), so you are getting the faster CPU without taking a value hit on paper.

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

Xeon W-10855M makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2020 vs 2018) and more multi-core headroom with 6 cores / 12 threads instead of 8/16. That extra compute headroom is more likely to matter as games, background tasks, and creator workloads get heavier.
