✅Integrated graphics onboard with UHD Graphics 770, while EPYC 7451 needs a discrete GPU.

Trade-offs

❌Smaller total L3 cache (24 MB vs 64 MB).
❌Less compelling for workstation-style loads than EPYC 7451, which brings 24 cores / 48 threads.
❌Launch MSRP is still $329 MSRP, while EPYC 7451 mostly shows up through inconsistent older-market listings.

EPYC 7451

2017

Why buy it

✅+166.7% larger total L3 cache (64 MB vs 24 MB).
✅Better for workstations and heavier parallel workloads: 24 cores / 48 threads.

Trade-offs

❌Worse for gaming: lower average FPS than Core i5-13600K across 16 shared CPU benchmark tests.
❌Lower PassMark (26,639 vs 37,655).
❌44% higher power demand at 180W vs 125W.
❌Older platform position on TR4 with DDR4, while Core i5-13600K moves to LGA1700 and DDR5.
