Core i3-11100B vs Xeon E-2186M: Pros, Cons & Final Verdict

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

Core i3-11100B

2021

Why buy it

✅+0.6% higher PassMark.
✅100+% more PCIe lanes (20 vs 0) for storage and expansion-heavy builds.
✅Integrated graphics onboard with UHD Graphics for 11th Gen (16 EU), while Xeon E-2186M needs a discrete GPU.

Trade-offs

❌Less compelling for workstation-style loads than Xeon E-2186M, which brings 6 cores / 12 threads.
❌44.4% higher power demand at 65W vs 45W.

Xeon E-2186M

2018

Why buy it

✅Better for workstations and heavier parallel workloads: 6 cores / 12 threads.
✅Draws 45W instead of 65W, a 20W reduction.

Trade-offs

❌Lower PassMark (11,285 vs 11,357).
❌No integrated graphics, while Core i3-11100B can still boot and troubleshoot without a discrete GPU.
❌No AVX-512 support for niche heavy compute workloads where it can matter.

Quick Answers

So, is Core i3-11100B better than Xeon E-2186M?

Not really, because they are built for different jobs. Xeon E-2186M makes more sense for workstation-style multi-core throughput, while Core i3-11100B 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, Core i3-11100B is the stronger fit. You are getting 0.6% better PassMark, backed by 4 cores and 8 threads.

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

Core i3-11100B still makes the most sense overall. Core i3-11100B comes in at an unclear MSRP at unclear MSRP versus unclear MSRP, and it still gives you 0.6% better PassMark.

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

Core i3-11100B makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2021 vs 2018), more multi-core headroom with 4 cores / 8 threads instead of 6/12, and AVX-512 support for heavier modern compute workloads. That extra compute headroom is more likely to matter as games, background tasks, and creator workloads get heavier.
