As of writing this article, Core i7-10710U is the top processor of the Comet Lake U line-up. Many users are asking for a comparison with the pretty popular high-end Whiskey Lake Core i7-8565U and now we can provide you that. We should note that Intel has risen the price with 8% for its newest best “ULV” performer, compared to i7-8565U ($443 vs $409 for 1000 units). But let’s see what you’ll get for that price.
Both chips are made through a 14nm manufacturing process and have 15W TDP. However, i7-10710U has 50% more Smart cache – 12MB vs 8MB for i7-8565U. The base frequency of i7-10710U is just 1.1GHz but it can reach the whooping 4.7GHz when needed, thanks to the Turbo Boost technology. The base level for i7-8565U is 1.80GHz going to 4.6GHz when boosted.
You’ll also notice the DDR4-2666 memory support while the Whiskey Lake CPU can work with up to DDR4-2400 RAM.
So what makes the i7-10710U so much better? In addition to the +50% cache size we already mentioned, it also has 50% more cores/threads! Core i7-10710U is equipped with 6 cores / 12 threads while i7-8565U has just 4 cores and 8 threads, respectively.
|Intel Core i7-10710U||Intel Core i7-8565U|
|Cores / Threads||6 / 12||4 / 8|
|Base / Max frequency||1.10 – 4.70 GHz||1.10 – 4.60 GHz|
|Cache||12 MB Intel Smart Cache||8 MB Intel Smart Cache|
|TDP / up / down||15W / 25W / 12.5W||15W / 25W / 10W|
|Memory support||DDR4-2666; LPDDR3-2133||DDR4-2400, LPDDR3-2133|
For this comparison, we chose two MSI devices – the new Prestige 15 vs the well-known PS63 Modern. The new generation leads its predecessor by more than 50%!
Results are from the Cinebench 20 CPU test (the higher the score, the better)
Results are from the Fritz chess benchmark (the higher the score, the better)
We won’t show you any GPU benchmarks here since the “new” UHD Graphics used in Comet Lake U is just a rebranded UHD Graphics 620.
Which one is for you – Core i7-10710U or i7-8565U?
If you’re going to work with massive 3D design or image editing applications you should make your conclusions based on the raw performance (check out our Top Laptop CPU Ranking page). Core i7-10710U is for those who want the perfect balance between high performance and portability.
We’re pretty impressed by the performance of the i7-10710U and given the little price difference we’d definitely choose it over the i7-8565U. However, there aren’t many notebooks with the new CPU on the market yet but that will change very soon.
