Kaby Lake R notebooks are still on the shelves no matter that the release date of those CPUs was back in 2017. It will be interesting to see what a two-year-old i7 CPU has to offer compared to a fresh product like Core i7-1065G7. The latter has a new tech process and new iGPU as well, so we’ll see if the old one can stand his ground in 2019.

Let the comparison begins.

Quick Specs

Intel is asking $426 for the new CPU – i7-1065G7 and $409 for i7-8650U. That’s not a big price difference. Core i7-1065G7 has a lower base frequency (1.30 GHz vs 1.90 GHz) but it can boost higher than i7-8650U (4.20 GHz to 3.30 GHz). Both CPUs have some identical specs – 4 cores and 8 threads, 8MB cache size, and almost the same TDP levels (i7-1065G7 has a bit higher TDP-down value).

You can clearly see the differences between the generations here – Core i7-1065G7 supports memories with much higher frequencies (DDR4-3200; LPDDR4-2133) than i7-8650U (DDR4-2400, LPDDR3-2133). Last but not least, the Ice Lake representative is equipped with the newest Intel Iris Plus G7 integrated graphics and we have Intel UHD 620 for i7-8650U.

Quick specs table:

	Intel Core i7-1065G7	Intel Core i7-8565U
Cores / Threads	4 / 8	4 / 8
Base / Max frequency	1.30 – 3.90 GHz	1.90 – 4.20 GHz
Cache	8 MB Intel Smart Cache	8 MB Intel Smart Cache
TDP / up / down	15W / 25W / 12W	15W / 25W / 10W
Memory support	DDR4-3200; LPDDR4-2133	DDR4-2400, LPDDR3-2133

CPU Benchmarks

Core i7-1065G7 is edging the i7-8650U with just 3% CPU performance difference. Both are very close.

GPU Benchmarks

Intel Iris Plus G7 is 45% faster than the UHD 620. Well, that’s bad news for i7-8650U.

Verdict

We think that our benchmarks above show everything. The two CPUs have almost the same CPU performance (ok, the new one is 3% faster) but when it comes to iGPU power the UHD 620 is crushed by the Intel Iris Plus G7 with 45% better score.

Intel Core i7-1065G7 costs $17 more (bulk price) but for us, it is the better choice because the overall performance is better. Still, the i7-8650U is not a bad CPU and if you find a nicely discounted notebook with it (and you don’t need better graphics performance) this will be the right choice because its CPU performance is still completely fine.
