Core i7-9700K
2018Why buy it
- ✅Better for gaming: +47.0% higher average FPS across 4 shared CPU benchmark tests.
- ✅+20% larger total L3 cache (12 MB vs 10 MB).
- ✅100+% more PCIe lanes (16 vs 0) for storage and expansion-heavy builds.
- ✅Integrated graphics onboard with UHD Graphics 630, while Core Ultra 5 115U needs a discrete GPU.
Trade-offs
- ❌Launch MSRP is still $385 MSRP, while Core Ultra 5 115U mostly shows up through inconsistent older-market listings.
- ❌Older platform position on LGA1151 with DDR4, while Core Ultra 5 115U moves to FCBGA2049 and DDR5.
Core Ultra 5 115U
2023Why buy it
- ✅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 4 shared CPU benchmark tests.
- ❌Lower PassMark (11,518 vs 14,397).
- ❌Smaller total L3 cache (10 MB vs 12 MB).
- ❌No integrated graphics, while Core i7-9700K can still boot and troubleshoot without a discrete GPU.
