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

✅Draws 65W instead of 115W, a 50W reduction.
✅Integrated graphics onboard with UHD Graphics for 11th Gen (16 EU), while Xeon E5-2670 v2 needs a discrete GPU.
✅AVX-512 support for select workstation, AI, and scientific workloads.

Trade-offs

❌Smaller total L3 cache (12 MB vs 25 MB).
❌Less compelling for workstation-style loads than Xeon E5-2670 v2, which brings 10 cores / 20 threads and 40 PCIe lanes.

Xeon E5-2670 v2

2013

Why buy it

✅+108.3% larger total L3 cache (25 MB vs 12 MB).
✅Better for workstations and heavier parallel workloads: 10 cores / 20 threads, plus 40 PCIe lanes vs 20.
✅100% more PCIe lanes (40 vs 20) for storage and expansion-heavy builds.

Trade-offs

❌Lower PassMark (11,346 vs 11,357).
❌Launch MSRP is still $1,556 MSRP, while Core i3-11100B mostly shows up through inconsistent older-market listings.
❌76.9% higher power demand at 115W vs 65W.
❌No integrated graphics, while Core i3-11100B can still boot and troubleshoot without a discrete GPU.

Quick Answers

So, is Core i3-11100B better than Xeon E5-2670 v2?

Not really, because they are built for different jobs. Xeon E5-2670 v2 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 gaming?

If gaming is the priority, Core i3-11100B is the better pick. According to our tests, it delivers 1.4% 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, Core i3-11100B is the stronger fit. You are getting 0.1% better PassMark, backed by 4 cores and 8 threads.

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

Core i3-11100B is still the faster CPU overall, but Xeon E5-2670 v2 is easier to justify if budget matters more than peak performance. Core i3-11100B comes in at an unclear MSRP at unclear MSRP versus $1,556 MSRP, and it still gives you a 1.4% average FPS lead across 50 shared CPU game tests in our data. Xeon E5-2670 v2 is also 100.0% better value on MSRP (7.3 vs 0.0 PassMark/$), 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 i3-11100B makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2021 vs 2013), more multi-core headroom with 4 cores / 8 threads instead of 10/20, 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.
