Intel Core Ultra 5 135H vs Intel Core Ultra 5 235H: Comparison
Core Ultra 5 135H vs Core Ultra 5 235H: the total threads difference
These two are close on paper, and total threads is the only measure that separates them at all: Core Ultra 5 135H 18 against Core Ultra 5 235H 14. Memory type is not the same on both, DDR5, LPDDR5/X on the Core Ultra 5 135H versus LPDDR5/x up to 8400 MT/s, DDR5 up to 6400... on the Core Ultra 5 235H. Npu peak tops is not the same on both, 11 TOPS on the Core Ultra 5 135H versus 13 TOPS on the Core Ultra 5 235H.
Core Ultra 5 135H vs Core Ultra 5 235H: which one fits your build
The Core Ultra 5 135H is the one to take for everyday laptop computing and on-device AI features, though it is the wrong buy for gaming laptops and heavy sustained workloads. The Core Ultra 5 235H suits business laptops managed by IT with Intel vPro and coding, photo editing and heavy multitasking, though it is not built for copilot+ PC AI features, which need a 40+ TOPS NPU and demanding modern games without a dedicated GPU. Avoid it for home buyers who do not need vPro and want the lowest price. Our rating of the Core Ultra 5 135H (8.3/10): the Intel Core Ultra 5 135H is the higher-binned half of Intel's H-series Meteor Lake pair, well suited to premium laptops that want a bit more headroom than the 125H.
Where the two are identical
Everything else lines up. Total cores, performance cores, efficiency cores, tdp and l3 cache read the same on both, so those are not worth weighing. They match on 6 further specifications as well.
Do the Core Ultra 5 135H and Core Ultra 5 235H differ on p-core boost clock?
Yes. P-Core Boost Clock reads 4.6 GHz on the Core Ultra 5 135H versus 5 GHz on the Core Ultra 5 235H.
Is the Integrated Graphics the same on the Core Ultra 5 135H and Core Ultra 5 235H?
It is. Both are listed at Yes, so it is not a reason to pick one over the other.
