The upcoming Ice Lake processor recently posted an impressive set of Geekbench scores, and now a set of SiSoftware benchmark results point to the CPU reaching up to 65 W. The quad-core processor will have a 3.9 GHz boost clock along with 2 MB of L2 cache and 8 MB of L3 cache too.

The Core i7-1065G7 has popped up again online, having appeared on Geekbench last week in a new HP Spectre x360 and a few months ago in the upcoming XPS 13 7390 2-in-1. The listing confirmed that the Ice Lake chip has four cores, can execute up to eight threads simultaneously and has a 15 W stock thermal design power (TDP). However, the CPU has now appeared on SiSoftware, with the website claiming that it can boost its TDP up to 65 W.

This would be a huge power draw for what we expect to be a U series processor. We would recommend taking this with a pinch of salt though, as SiSoftware also claims that the Core i7-8565U in the XPS 13 9380 can reach up to 64.5 W, which is not the case. The SiSoftware listing does re-affirm that the Core i7-1065G7 can reach up to 3.9 GHz, with the CPU also having 2 MB of L2 and 8 MB of L3 caches. By contrast, the Core i7-8565U has just 1 MB of L2 cache but also has 8 MB of L3.

According to previous leaks, the Core i7-1065G7 will have a 1.5 GHz base clock speed, which is significantly lower than its Whiskey Lake counterparts. This improved efficiency at lower clock speeds may be down to the switch from 14 nm to 10 nm FinFET manufacturing. The CPU appears to offer healthy single and multi-core performance improvements over the Core i7-8565U too, although it is too early to say whether the jump to 10 nm will bring anything other than just better performance.
