Core i7-9700K

2018

Why buy it

✅Better for gaming: +50.0% higher average FPS across 2 shared CPU benchmark tests.
✅+50% larger total L3 cache (12 MB vs 8 MB).
✅100+% more PCIe lanes (16 vs 0) for storage and expansion-heavy builds.
✅Integrated graphics onboard with UHD Graphics 630, while U300 needs a discrete GPU.

Trade-offs

❌Launch MSRP is still $385 MSRP, while U300 mostly shows up through inconsistent older-market listings.
❌72.7% higher power demand at 95W vs 55W.
❌Older platform position on LGA1151 with DDR4, while U300 moves to FCBGA1744 and DDR5.

U300

2023

Why buy it

✅Draws 55W instead of 95W, a 40W reduction.
✅Newer platform on FCBGA1744 with DDR5 support instead of LGA1151 and DDR4.

Trade-offs

❌Worse for gaming: lower average FPS than Core i7-9700K across 2 shared CPU benchmark tests.
❌Lower PassMark (8,492 vs 14,397).
❌Smaller total L3 cache (8 MB vs 12 MB).
❌No integrated graphics, while Core i7-9700K can still boot and troubleshoot without a discrete GPU.
