Quick Answers

So, is Core i5-12600H better than Xeon W-2155?

Not really, because they are built for different jobs. Xeon W-2155 makes more sense for workstation-style multi-core throughput, while Core i5-12600H is the more practical desktop choice for gaming, platform cost, and everyday use.

Which one is better for gaming?

For gaming, this matchup is basically a tie in the data we have.

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

For streaming, content creation, and heavier multitasking, Core i5-12600H is the stronger fit. You are getting 0.1% better PassMark, backed by 12 cores and 16 threads. It also has the larger cache pool with 30.9% larger total L3 cache (18 MB vs 14 MB).

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

Core i5-12600H is still the faster CPU overall, but Xeon W-2155 is easier to justify if budget matters more than peak performance. Core i5-12600H comes in at an unclear MSRP at unclear MSRP versus $1,440 MSRP, and it still gives you a 0.6% average FPS lead across 50 shared CPU game tests in our data. Xeon W-2155 is also 100.0% better value on MSRP (14.5 vs 0.0 PassMark/$), which is why it can still make sense for tighter-budget builds on paper.

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

Core i5-12600H makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2022 vs 2017), a healthier platform with FCBGA1744 and DDR5 instead of LGA2066, 30.9% larger total L3 cache (18 MB vs 14 MB), and more multi-core headroom with 12 cores / 16 threads instead of 10/20. That gives you a healthier platform runway for motherboard, RAM, and later CPU upgrades.
