Intel 8th Gen Intel Core i5 8265U vs Intel 10th Gen Intel Core i7 10510U: Comparison
8th Gen Intel Core i5 8265U vs 10th Gen Intel Core i7 10510U: the l3 cache difference
On l3 cache the spread is 25%, 8th Gen Intel Core i5 8265U 6 MB against 10th Gen Intel Core i7 10510U 8 MB, so 10th Gen Intel Core i7 10510U takes it. Igpu is not the same on both, Intel UHD Graphics 620 on the 8th Gen Intel Core i5 8265U versus Intel UHD Graphics for 10th Gen Intel Processors on the 10th Gen Intel Core i7 10510U. Microarchitecture is not the same on both, Whiskey Lake, 8th Gen Intel Core on the 8th Gen Intel Core i5 8265U versus Comet Lake, 10th Gen Intel Core on the 10th Gen Intel Core i7 10510U. They differ on memory type too, DDR4, LPDDR3 on the 8th Gen Intel Core i5 8265U versus DDR4-2666, LPDDR3-2133, LPDDR4-2933 on the 10th Gen Intel Core i7 10510U.
Which should you buy, 8th Gen Intel Core i5 8265U or 10th Gen Intel Core i7 10510U?
The 8th Gen Intel Core i5 8265U is the one to take for 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. The 10th Gen Intel Core i7 10510U suits mainstream thin-and-light productivity laptops wanting strong single-thread responsiveness. It is not the one for sustained multi-threaded workloads, the 4-core count is a real ceiling compared to H-series chips.
Where the two are identical
Everything else lines up. Total cores, performance cores, efficiency cores, total threads and tdp read the same on both, so those are not worth weighing. They match on 6 further specifications as well.
Frequently asked questions
Do the 8th Gen Intel Core i5 8265U and 10th Gen Intel Core i7 10510U differ on p-core boost clock?
