Trade-offs

❌Smaller total L3 cache (25 MB vs 30 MB).
❌Less compelling for workstation-style loads than Xeon E5-4650 v3, which brings 12 cores / 24 threads.
❌Launch MSRP is still $409 MSRP, while Xeon E5-4650 v3 mostly shows up through inconsistent older-market listings.
❌19% higher power demand at 125W vs 105W.

Xeon E5-4650 v3

2015

Why buy it
