Intel 8th Gen Intel Core i5 8279U vs Intel 10th Gen Intel Core i7 10510U: Comparison
8th Gen Intel Core i5 8279U vs 10th Gen Intel Core i7 10510U: the l3 cache difference
Start with l3 cache, because it is the widest measured gap between them: 8th Gen Intel Core i5 8279U 6 MB against 10th Gen Intel Core i7 10510U 8 MB, 25% in favour of 10th Gen Intel Core i7 10510U. There is a split on microarchitecture as well, Coffee Lake, 8th Gen Intel Core on the 8th Gen Intel Core i5 8279U versus Comet Lake, 10th Gen Intel Core on the 10th Gen Intel Core i7 10510U. They differ on base power too, 28 W on the 8th Gen Intel Core i5 8279U versus 15 W on the 10th Gen Intel Core i7 10510U. They differ on memory type too, DDR4-2400, LPDDR3-2133 on the 8th Gen Intel Core i5 8279U versus DDR4-2666, LPDDR3-2133, LPDDR4-2933 on the 10th Gen Intel Core i7 10510U.
8th Gen Intel Core i5 8279U vs 10th Gen Intel Core i7 10510U: which one fits your build
Take the 8th Gen Intel Core i5 8279U for premium ultraportable laptops wanting genuinely stronger integrated graphics at a more accessible price than i7-tier options. Avoid it for buyers needing dedicated gaming or heavy creative graphics capability, a discrete GPU remains necessary for that. Buy the 10th Gen Intel Core i7 10510U for mainstream thin-and-light productivity laptops wanting strong single-thread responsiveness. It is the wrong buy for sustained multi-threaded workloads, the 4-core count is a real ceiling compared to H-series chips.
What 8th Gen Intel Core i5 8279U and 10th Gen Intel Core i7 10510U have in common
The common ground is wider than the gap: total cores, performance cores, efficiency cores, total threads and integrated graphics are identical here. They match on 6 further specifications as well.
Frequently asked questions
Do the 8th Gen Intel Core i5 8279U and 10th Gen Intel Core i7 10510U differ on p-core boost clock?
Yes. P-Core Boost Clock reads 4.1 GHz on the 8th Gen Intel Core i5 8279U versus 4.9 GHz on the 10th Gen Intel Core i7 10510U.
Is the Socket the same on the 8th Gen Intel Core i5 8279U and 10th Gen Intel Core i7 10510U?
It is. Both are listed at FCBGA1528, so it is not a reason to pick one over the other.
