Core i7-13700K

2022

Why buy it

✅Better for gaming: +21.2% higher average FPS across 50 shared CPU benchmark tests.
✅Draws 125W instead of 180W, a 55W reduction.
✅Newer platform on LGA1700 with DDR5 support instead of TR4 and DDR4.
✅100+% more PCIe lanes (20 vs 0) for storage and expansion-heavy builds.
✅Integrated graphics onboard with Intel UHD Graphics 770, while EPYC 7451 needs a discrete GPU.

Trade-offs

❌Smaller total L3 cache (30 MB vs 64 MB).
❌Less compelling for workstation-style loads than EPYC 7451, which brings 24 cores / 48 threads.
❌Launch MSRP is still $409 MSRP, while EPYC 7451 mostly shows up through inconsistent older-market listings.

EPYC 7451

2017

Why buy it

✅+113.3% larger total L3 cache (64 MB vs 30 MB).
✅Better for workstations and heavier parallel workloads: 24 cores / 48 threads.

Trade-offs

❌Worse for gaming: lower average FPS than Core i7-13700K across 50 shared CPU benchmark tests.
❌Lower PassMark (26,639 vs 45,784).
❌44% higher power demand at 180W vs 125W.
❌Older platform position on TR4 with DDR4, while Core i7-13700K moves to LGA1700 and DDR5.
❌No integrated graphics, while Core i7-13700K can still boot and troubleshoot without a discrete GPU.
