Core i3-12100E

2022

Why buy it

✅+700% larger total L3 cache (12 MB vs 1.5 MB).
✅Draws 60W instead of 65W, a 5W reduction.
✅Newer platform on LGA1700 with DDR5 support instead of FCBGA1667 and DDR4.
✅100+% more PCIe lanes (20 vs 0) for storage and expansion-heavy builds.
✅Integrated graphics onboard with UHD Graphics 730, while Xeon D-1587 needs a discrete GPU.

Trade-offs

❌Lower PassMark (13,535 vs 13,630).
❌Less compelling for workstation-style loads than Xeon D-1587, which brings 16 cores / 32 threads.

Xeon D-1587

2016

Why buy it

✅+0.7% higher PassMark.
✅Better for workstations and heavier parallel workloads: 16 cores / 32 threads.

Trade-offs

❌Smaller total L3 cache (1.5 MB vs 12 MB).
❌Launch MSRP is still $1,652 MSRP, while Core i3-12100E mostly shows up through inconsistent older-market listings.
❌Older platform position on FCBGA1667 with DDR4, while Core i3-12100E moves to LGA1700 and DDR5.
❌No integrated graphics, while Core i3-12100E can still boot and troubleshoot without a discrete GPU.

Quick Answers

So, is Core i3-12100E better than Xeon D-1587?

Not really, because they are built for different jobs. Xeon D-1587 makes more sense for workstation-style multi-core throughput, while Core i3-12100E 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, Xeon D-1587 is the stronger fit. You are getting 0.7% better PassMark, backed by 16 cores and 32 threads.

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

Core i3-12100E is the easy recommendation for a fresh desktop build. Core i3-12100E comes in at an unclear MSRP at unclear MSRP versus $1,652 MSRP, and it still gives you a 1.2% average FPS lead across 50 shared CPU game tests in our data. Xeon D-1587 only looks good on raw value math because it is a cheap legacy laptop chip, not because it is a real desktop gaming recommendation. It simply does not keep up in modern games, especially when the gap is already 1.2% in the shared gaming data.

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

Core i3-12100E makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2022 vs 2016), a healthier platform with LGA1700 and DDR5 instead of FCBGA1667, and 700% larger total L3 cache (12 MB vs 1.5 MB). That gives you a healthier platform runway for motherboard, RAM, and later CPU upgrades.
