✅100+% more PCIe lanes (20 vs 0) for storage and expansion-heavy builds.
✅Includes a boxed cooler (Yes), unlike Xeon E5-2696 V3.

Trade-offs

❌Worse for gaming: lower average FPS than Xeon E5-2696 V3 across 5 shared CPU benchmark tests.
❌Lower PassMark (19,532 vs 21,435).
❌Smaller total L3 cache (18 MB vs 45 MB).
❌Less compelling for workstation-style loads than Xeon E5-2696 V3, which brings 18 cores / 36 threads.
❌Launch MSRP is still $174 MSRP, while Xeon E5-2696 V3 mostly shows up through inconsistent older-market listings.
