Core i3-11100B

2021

Why buy it

✅Draws 65W instead of 115W, a 50W reduction.
✅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 E5-4657L v2 needs a discrete GPU.

Trade-offs

❌Worse for gaming: lower average FPS than Xeon E5-4657L v2 across 50 shared CPU benchmark tests.
❌Lower PassMark (11,357 vs 11,613).
❌Smaller total L3 cache (12 MB vs 30 MB).
❌Less compelling for workstation-style loads than Xeon E5-4657L v2, which brings 12 cores / 24 threads.

Xeon E5-4657L v2

2014

Why buy it

✅Better for gaming: +4.1% higher average FPS across 50 shared CPU benchmark tests.
✅+150% larger total L3 cache (30 MB vs 12 MB).
✅Better for workstations and heavier parallel workloads: 12 cores / 24 threads.

Trade-offs

❌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.
❌No AVX-512 support for niche heavy compute workloads where it can matter.

Quick Answers

So, is Xeon E5-4657L v2 better than Core i3-11100B?

Not really, because they are built for different jobs. Xeon E5-4657L 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.
