Intel 8th Gen Intel Core i3 8145U vs Intel 11th Gen Intel Core i5 11400H: Comparison
8th Gen Intel Core i3 8145U vs 11th Gen Intel Core i5 11400H l3 cache compared
The gap that matters here is l3 cache: 8th Gen Intel Core i3 8145U 4 MB against 11th Gen Intel Core i5 11400H 12 MB, which puts 11th Gen Intel Core i5 11400H 67% ahead. Tdp is not the same on both, 15 W on the 8th Gen Intel Core i3 8145U versus 45 W on the 11th Gen Intel Core i5 11400H. They differ on socket too, FCBGA1528 on the 8th Gen Intel Core i3 8145U versus FCBGA1787 on the 11th Gen Intel Core i5 11400H. There is a split on product line as well, Core i3 on the 8th Gen Intel Core i3 8145U versus Core i5 on the 11th Gen Intel Core i5 11400H.
Who each one is for
Take the 8th Gen Intel Core i3 8145U for budget mainstream laptops wanting solid entry-level performance with hyperthreaded multitasking capability. It is the wrong buy for buyers needing more than 2 physical cores for any real multitasking headroom. The 11th Gen Intel Core i5 11400H suits mainstream gaming laptops wanting solid 6-core Tiger Lake H performance. Avoid it for buyers needing more than 6 cores for sustained multi-threaded work, the 8-core i7/i9 H-series chips of the same generation offer more.
Where the two are identical
Where they agree, they agree completely, efficiency cores, integrated graphics, form factor, market segment and smt enabled included, so the decision does not turn on any of those.
