✅Draws 65W instead of 180W, a 115W 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 UHD 730, while EPYC 7451 needs a discrete GPU.

Trade-offs

❌Smaller total L3 cache (20 MB vs 64 MB).
❌Less compelling for workstation-style loads than EPYC 7451, which brings 24 cores / 48 threads.
❌Launch MSRP is still $221 MSRP, while EPYC 7451 mostly shows up through inconsistent older-market listings.

EPYC 7451

2017

Why buy it

✅+220% larger total L3 cache (64 MB vs 20 MB).
✅Better for workstations and heavier parallel workloads: 24 cores / 48 threads.

Trade-offs

❌Worse for gaming: lower average FPS than Core i5-13400E across 4 shared CPU benchmark tests.
❌Lower PassMark (26,639 vs 27,000).
