Intel Core Ultra 7 266V vs Intel Core Ultra X7 368H: Comparison
Core Ultra 7 266V vs Core Ultra X7 368H: the l3 cache difference
The gap that matters here is l3 cache: Core Ultra 7 266V 12 MB against Core Ultra X7 368H 18 MB, which puts Core Ultra X7 368H 33% ahead. There is a split on release year as well, 2024 on the Core Ultra 7 266V versus 2026 on the Core Ultra X7 368H. There is a split on igpu as well, Intel Arc 140V GPU on the Core Ultra 7 266V versus Intel Arc B390 on the Core Ultra X7 368H.
Which should you buy, Core Ultra 7 266V or Core Ultra X7 368H?
Buy the Core Ultra 7 266V for Ultra-thin and light laptops and all-day battery life, though it is the wrong buy for heavy sustained multi-core workloads and gaming laptops. Take the Core Ultra X7 368H for thin laptops that lean on the 12-core Intel Arc B390 iGPU instead of a discrete graphics chip. The same goes for buyers who want local AI features backed by the 50 TOPS NPU 5 in a 25 W laptop part. Avoid it for desktop builders, since this is a laptop-only FCBGA2540 package with no socket. Our rating of the Core Ultra 7 266V (9/10): the Intel Core Ultra 7 266V is a non-vPro Lunar Lake variant for consumer ultra-thin laptops wanting more headroom than the Core Ultra 5 tier.
Where the two are identical
Everything else lines up. Performance cores, p-core boost clock, integrated graphics, form factor and market segment read the same on both, so those are not worth weighing. They match on 1 further specification as well.
Do the Core Ultra 7 266V and Core Ultra X7 368H differ on total cores?
Yes. Total Cores reads 8 on the Core Ultra 7 266V versus 16 on the Core Ultra X7 368H.
Is the SMT Enabled the same on the Core Ultra 7 266V and Core Ultra X7 368H?
It is. Both are listed at No, so it is not a reason to pick one over the other.
