Intel 8th Gen Intel Core i5 8365U vs Intel 10th Gen Intel Core i7-10870H: Comparison
8th Gen Intel Core i5 8365U vs 10th Gen Intel Core i7-10870H l3 cache compared
L3 cache is where these two genuinely part company, 8th Gen Intel Core i5 8365U 6 MB against 10th Gen Intel Core i7-10870H 16 MB, a 63% lead for 10th Gen Intel Core i7-10870H. L2 cache runs the same way, 1 MB on the 8th Gen Intel Core i5 8365U versus 2 MB on the 10th Gen Intel Core i7-10870H, another win for 10th Gen Intel Core i7-10870H. There is a split on tdp as well, 15 W on the 8th Gen Intel Core i5 8365U versus 45 W on the 10th Gen Intel Core i7-10870H. There is a split on socket as well, FCBGA1528 on the 8th Gen Intel Core i5 8365U versus FCBGA1440 on the 10th Gen Intel Core i7-10870H.
Which should you buy, 8th Gen Intel Core i5 8365U or 10th Gen Intel Core i7-10870H?
The 8th Gen Intel Core i5 8365U suits mainstream thin-and-light laptops wanting solid 4-core Whiskey Lake performance. Avoid it for buyers with access to newer generations, considerably more recent U-series chips offer meaningful IPC and efficiency gains. Take the 10th Gen Intel Core i7-10870H for content creation and gaming laptops wanting full 8-core Comet Lake performance with a high single-thread clock ceiling. It is the wrong buy for buyers on a tighter budget not needing the full 8-core count, the 6-core i7-10750H offers similar single-thread clocks for less.
What 8th Gen Intel Core i5 8365U and 10th Gen Intel Core i7-10870H have in common
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.
