Intel Core i9-13905H vs Intel Core Ultra 5 135H: Comparison
Core i9-13905H vs Core Ultra 5 135H performance cores compared
These two are close on paper, and performance cores is the only measure that separates them at all: Core i9-13905H 6 against Core Ultra 5 135H 4. L3 cache runs the same way, 24 MB on the Core i9-13905H versus 18 MB on the Core Ultra 5 135H, another win for Core i9-13905H. They differ on socket too, FCBGA1792 on the Core i9-13905H versus FCBGA2049 on the Core Ultra 5 135H. Igpu is not the same on both, Intel Iris Xe Graphics on the Core i9-13905H versus Intel Arc graphics on the Core Ultra 5 135H.
Who each one is for
Buy the Core i9-13905H for premium laptops and everyday productivity, though it is not the pick for Ultra-thin fanless laptops and maximum battery life. 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. Our rating of the Core i9-13905H (8.3/10): the Intel Core i9-13905H is a well-rounded performance mobile chip, suited to premium laptops balancing power and portability. 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
The common ground is wider than the gap: total cores, integrated graphics, form factor, release year and market segment are identical here. They match on 2 further specifications as well.
