Core i7-9700K

2018

Why buy it

✅Better for gaming: +11.5% higher average FPS across 12 shared CPU benchmark tests.
✅100+% more PCIe lanes (16 vs 0) for storage and expansion-heavy builds.
✅Integrated graphics onboard with UHD Graphics 630, while Core Ultra 7 155U needs a discrete GPU.

Trade-offs

❌Lower PassMark (14,397 vs 16,185).
❌Launch MSRP is still $385 MSRP, while Core Ultra 7 155U mostly shows up through inconsistent older-market listings.
❌Older platform position on LGA1151 with DDR4, while Core Ultra 7 155U moves to FCBGA2049 and DDR5.

Core Ultra 7 155U

2023

Why buy it

✅+12.4% higher PassMark.
✅Newer platform on FCBGA2049 with DDR5 support instead of LGA1151 and DDR4.

Trade-offs

❌Worse for gaming: lower average FPS than Core i7-9700K across 12 shared CPU benchmark tests.
❌No integrated graphics, while Core i7-9700K can still boot and troubleshoot without a discrete GPU.
