Intel 8th Gen Intel Core i5 8279U vs Intel 8th Gen Intel Core i5 8300H: Comparison
8th Gen Intel Core i5 8279U vs 8th Gen Intel Core i5 8300H: the l3 cache difference
L3 cache is where these two genuinely part company, 8th Gen Intel Core i5 8279U 6 MB against 8th Gen Intel Core i5 8300H 8 MB, a 25% lead for 8th Gen Intel Core i5 8300H. There is a split on base power as well, 28 W on the 8th Gen Intel Core i5 8279U versus 45 W on the 8th Gen Intel Core i5 8300H. They differ on memory type too, DDR4-2400, LPDDR3-2133 on the 8th Gen Intel Core i5 8279U versus DDR4-2666, LPDDR3-2133 on the 8th Gen Intel Core i5 8300H.
Who each one is for
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. Take the 8th Gen Intel Core i5 8300H for mid-range gaming laptops wanting solid 4-core performance at a lower price than 6-core i7 options. It is the wrong buy for buyers needing strong multi-threaded performance, the 6-core i7 8750H offers meaningfully more within the same generation.
