Core i3-11100B

2021

Why buy it

✅Better for gaming: +5.2% higher average FPS across 50 shared CPU benchmark tests.
✅Draws 65W instead of 125W, a 60W 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 Bronze 3508U needs a discrete GPU.

Trade-offs

❌Smaller total L3 cache (12 MB vs 23 MB).
❌Less compelling for workstation-style loads than Xeon Bronze 3508U, which brings 8 cores / 8 threads.

Xeon Bronze 3508U

2023

Why buy it

✅+87.5% larger total L3 cache (23 MB vs 12 MB).
✅Better for workstations and heavier parallel workloads: 8 cores / 8 threads.

Trade-offs

❌Worse for gaming: lower average FPS than Core i3-11100B across 50 shared CPU benchmark tests.
❌Lower PassMark (11,248 vs 11,357).
❌92.3% higher power demand at 125W vs 65W.
❌No integrated graphics, while Core i3-11100B can still boot and troubleshoot without a discrete GPU.

Quick Answers
