Core i7-9700K

2018

Why buy it

✅Better for gaming: +20.7% higher average FPS across 4 shared CPU benchmark tests.
✅Draws 95W instead of 120W, a 25W reduction.
✅100+% more PCIe lanes (16 vs 0) for storage and expansion-heavy builds.
✅Integrated graphics onboard with UHD Graphics 630, while Xeon E5-2683 v3 needs a discrete GPU.

Trade-offs

❌Lower PassMark (14,397 vs 14,686).
❌Smaller total L3 cache (12 MB vs 35 MB).
❌Less compelling for workstation-style loads than Xeon E5-2683 v3, which brings 14 cores / 28 threads.
❌Launch MSRP is still $385 MSRP, while Xeon E5-2683 v3 mostly shows up through inconsistent older-market listings.

Xeon E5-2683 v3

2014

Why buy it

✅+2% higher PassMark.
✅+191.7% larger total L3 cache (35 MB vs 12 MB).
✅Better for workstations and heavier parallel workloads: 14 cores / 28 threads.

Trade-offs

❌Worse for gaming: lower average FPS than Core i7-9700K across 4 shared CPU benchmark tests.
❌26.3% higher power demand at 120W vs 95W.
❌No integrated graphics, while Core i7-9700K can still boot and troubleshoot without a discrete GPU.
