Core i5-12400T

2022

Why buy it

✅Better for gaming: +3.2% higher average FPS across 4 shared CPU benchmark tests.
✅+30.9% larger total L3 cache (18 MB vs 14 MB).
✅Draws 35W instead of 85W, a 50W reduction.
✅Newer platform on LGA1700 with DDR5 support instead of LGA3647 and DDR4.
✅100+% more PCIe lanes (20 vs 0) for storage and expansion-heavy builds.

Trade-offs

❌Lower PassMark (15,543 vs 15,757).
❌Less compelling for workstation-style loads than Xeon Gold 5215, which brings 10 cores / 20 threads.
❌Launch MSRP is still $192 MSRP, while Xeon Gold 5215 mostly shows up through inconsistent older-market listings.

Xeon Gold 5215

2019

Why buy it

✅+1.4% higher PassMark.
✅Better for workstations and heavier parallel workloads: 10 cores / 20 threads.

Trade-offs

❌Worse for gaming: lower average FPS than Core i5-12400T across 4 shared CPU benchmark tests.
❌Smaller total L3 cache (14 MB vs 18 MB).
❌142.9% higher power demand at 85W vs 35W.
❌Older platform position on LGA3647 with DDR4, while Core i5-12400T moves to LGA1700 and DDR5.
❌No integrated graphics, while Core i5-12400T can still boot and troubleshoot without a discrete GPU.
