Core i7-11700

2021

Why buy it

✅Draws 65W instead of 80W, a 15W reduction.
✅100+% more PCIe lanes (20 vs 0) for storage and expansion-heavy builds.
✅Integrated graphics onboard with UHD Graphics 750, while Xeon E-2456 needs a discrete GPU.
✅Includes a boxed cooler (Stock), unlike Xeon E-2456.

Trade-offs

❌Worse for gaming: lower average FPS than Xeon E-2456 across 50 shared CPU benchmark tests.
❌Lower PassMark (20,625 vs 20,705).
❌Launch MSRP is still $323 MSRP, while Xeon E-2456 mostly shows up through inconsistent older-market listings.
❌Older platform position on LGA1200 with DDR4, while Xeon E-2456 moves to LGA1700 and DDR5.

Xeon E-2456

2023

Why buy it

✅Better for gaming: +5.9% higher average FPS across 50 shared CPU benchmark tests.
✅Newer platform on LGA1700 with DDR5 support instead of LGA1200 and DDR4.

Trade-offs

❌23.1% higher power demand at 80W vs 65W.
❌No integrated graphics, while Core i7-11700 can still boot and troubleshoot without a discrete GPU.
❌No boxed cooler included, unlike Core i7-11700.

Quick Answers

So, is Xeon E-2456 better than Core i7-11700?

Not really, because they are built for different jobs. Xeon E-2456 makes more sense for workstation-style multi-core throughput, while Core i7-11700 is the more practical desktop choice for gaming, platform cost, and everyday use.

Which one is better for gaming?

If gaming is the priority, Xeon E-2456 is the better pick. According to our tests, it delivers 5.9% 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, Xeon E-2456 is the stronger fit. You are getting 0.4% better PassMark, backed by 6 cores and 12 threads.

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

Xeon E-2456 is still the faster CPU overall, but Core i7-11700 is easier to justify if budget matters more than peak performance. Xeon E-2456 comes in at an unclear MSRP at unclear MSRP versus $323 MSRP, and it still gives you a 5.9% average FPS lead across 50 shared CPU game tests in our data. Core i7-11700 is also 100.0% better value on MSRP (63.9 vs 0.0 PassMark/$), which is why it can still make sense for tighter-budget builds on paper.

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

Xeon E-2456 makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2023 vs 2021), a healthier platform with LGA1700 and DDR5 instead of LGA1200, and more multi-core headroom with 6 cores / 12 threads instead of 8/16. That gives you a healthier platform runway for motherboard, RAM, and later CPU upgrades.
