Core i5-1235U vs Xeon E5-2685 v3: Pros, Cons & Final Verdict
See where each CPU makes more sense in practice: gaming, heavier work, platform cost, power draw, and upgrade path.
Core i5-1235U
2022Why buy it
- ✅Better for gaming: +11.3% higher average FPS across 50 shared CPU benchmark tests.
- ✅Draws 15W instead of 120W, a 105W reduction.
- ✅Newer platform on FCBGA1744 with DDR5 support instead of LGA2011-3 and DDR4.
- ✅100+% more PCIe lanes (20 vs 0) for storage and expansion-heavy builds.
- ✅Integrated graphics onboard with Iris Xe Graphics 80EU, while Xeon E5-2685 v3 needs a discrete GPU.
Trade-offs
- ❌Lower PassMark (12,740 vs 12,944).
- ❌Smaller total L3 cache (12 MB vs 30 MB).
- ❌Less compelling for workstation-style loads than Xeon E5-2685 v3, which brings 12 cores / 12 threads.
Xeon E5-2685 v3
2014Why buy it
- ✅+1.6% higher PassMark.
- ✅+150% larger total L3 cache (30 MB vs 12 MB).
- ✅Better for workstations and heavier parallel workloads: 12 cores / 12 threads.
Trade-offs
- ❌Worse for gaming: lower average FPS than Core i5-1235U across 50 shared CPU benchmark tests.
- ❌Launch MSRP is still $2,090 MSRP, while Core i5-1235U mostly shows up through inconsistent older-market listings.
- ❌700% higher power demand at 120W vs 15W.
- ❌Older platform position on LGA2011-3 with DDR4, while Core i5-1235U moves to FCBGA1744 and DDR5.
- ❌No integrated graphics, while Core i5-1235U can still boot and troubleshoot without a discrete GPU.
