Intel Core i9-14900HX vs Intel Core Ultra 9 290HX Plus: Comparison
Core i9-14900HX vs Core Ultra 9 290HX Plus: the total threads difference
These two are close on paper, and total threads is the only measure that separates them at all: Core i9-14900HX 32 against Core Ultra 9 290HX Plus 24. Measured rather than claimed: in Cinebench 2024 (Multi-Core) the Core Ultra 9 290HX Plus returns 2,104 against 1,763, a 16% lead. Add l2 cache to that, 32 MB on the Core i9-14900HX versus 40 MB on the Core Ultra 9 290HX Plus, and the pattern holds. Core Ultra 9 290HX Plus also leads on pcie lanes, 20 on the Core i9-14900HX versus 24 on the Core Ultra 9 290HX Plus.
Core i9-14900HX vs Core Ultra 9 290HX Plus: which one fits your build
Buy the Core i9-14900HX for high-end gaming laptops and mobile content creation, though it is not built for thin-and-light laptops and battery-life-focused use. The Core Ultra 9 290HX Plus suits flagship gaming laptops with high-end graphics cards and mobile workstations for video editing, 3D rendering and code builds, though it is the wrong buy for thin and light laptops where battery life comes first and copilot+ PC AI features, which need a 40+ TOPS NPU. It is the wrong buy for gamers on a budget, where a Core Ultra 7 HX laptop gets close for less.
What Core i9-14900HX and Core Ultra 9 290HX Plus have in common
The common ground is wider than the gap: total cores, performance cores, efficiency cores, tdp and l3 cache are identical here. They match on 8 further specifications as well.
Do the Core i9-14900HX and Core Ultra 9 290HX Plus differ on p-core boost clock?
Yes. P-Core Boost Clock reads 5.8 GHz on the Core i9-14900HX versus 5.5 GHz on the Core Ultra 9 290HX Plus.
Is the Integrated Graphics the same on the Core i9-14900HX and Core Ultra 9 290HX Plus?
It is. Both are listed at Yes, so it is not a reason to pick one over the other.
