Core i7-9700K

2018

Why buy it

✅Better for gaming: +8.6% higher average FPS across 47 shared CPU benchmark tests.
✅Draws 95W instead of 130W, a 35W reduction.
✅100+% more PCIe lanes (16 vs 0) for storage and expansion-heavy builds.
✅Integrated graphics onboard with UHD Graphics 630, while Xeon E7-8880 v2 needs a discrete GPU.

Trade-offs

❌Lower PassMark (14,397 vs 25,966).
❌Smaller total L3 cache (12 MB vs 38 MB).
❌Less compelling for workstation-style loads than Xeon E7-8880 v2, which brings 15 cores / 30 threads.
❌Launch MSRP is still $385 MSRP, while Xeon E7-8880 v2 mostly shows up through inconsistent older-market listings.

Xeon E7-8880 v2

2014

Why buy it

✅+80.4% higher PassMark.
✅+212.5% larger total L3 cache (38 MB vs 12 MB).
✅Better for workstations and heavier parallel workloads: 15 cores / 30 threads.

Trade-offs

❌Worse for gaming: lower average FPS than Core i7-9700K across 47 shared CPU benchmark tests.
