✅+200% larger total L3 cache (24 MB vs 8 MB).
✅Newer platform on LGA1700 with DDR5 support instead of LGA1151 and DDR4.
✅100+% more PCIe lanes (20 vs 0) for storage and expansion-heavy builds.
✅Integrated graphics onboard with UHD Graphics 770, while Xeon E3-1245 v6 needs a discrete GPU.

Trade-offs

❌Launch MSRP is still $329 MSRP, while Xeon E3-1245 v6 mostly shows up through inconsistent older-market listings.
❌71.2% higher power demand at 125W vs 73W.

Xeon E3-1245 v6

2017

Why buy it

✅Draws 73W instead of 125W, a 52W reduction.

Trade-offs

❌Worse for gaming: lower average FPS than Core i5-13600K across 2 shared CPU benchmark tests.
❌Lower PassMark (8,711 vs 37,655).
❌Smaller total L3 cache (8 MB vs 24 MB).
❌Older platform position on LGA1151 with DDR4, while Core i5-13600K moves to LGA1700 and DDR5.
❌No integrated graphics, while Core i5-13600K can still boot and troubleshoot without a discrete GPU.
