Intel Core i7-8565U
A 15W Whiskey Lake refresh of Intel's 8th-gen U-series, keeping the same quad-core, eight-thread layout as its Kaby Lake Refresh predecessor but pushing boost clocks to 4.6GHz. It remained Intel's mainstream thin-and-light chip through 2018-2020.
Pros
- Boosts to 4.6GHz, among the highest single-core clocks in Intel's 8th-gen U-series lineup (only the vPro-focused i7-8665U clocks higher, at 4.8GHz)
- Quad-core, eight-thread design handles multitasking well for a 15W part
- 8MB L3 cache, up from 6MB on entry-level i5 SKUs of the same generation
- Supports up to 64GB of DDR4-2400 or LPDDR3-2133 memory
- Configurable to 25W cTDP-up for sustained turbo in well-cooled chassis
Cons
- Base clock is only 1.8GHz; sustained multi-core loads run well under the boost figure
- Same 14nm process and UHD Graphics 620 iGPU as the previous two generations
- UHD Graphics 620 iGPU offers no meaningful gaming performance
- An iterative refresh over the i7-8550U with limited real-world gains
Awaiting benchmarks
No Inno Score yet: single-core still needs a published benchmark result.

Quick answers
Is the Intel Core i7-8565U good in 2026?
We haven't scored the Intel Core i7-8565U yet: there are no published single-core benchmark results for it in our database, and we don't score chips on their spec sheet alone. A 15W Whiskey Lake refresh of Intel's 8th-gen U-series, keeping the same quad-core, eight-thread layout as its Kaby Lake Refresh predecessor but pushing boost clocks to 4.6GHz. It remained Intel's mainstream thin-and-light chip through 2018-2020.
Does the Intel Core i7-8565U count as "Core i7 or equivalent"?
Its PassMark CPU Mark average is 5,935 (cpubenchmark.net, retrieved Sep 26, 2026), which puts it in Tier D of our CPU tier checker: legacy Core i7 and budget chips, slower than recent Core i5 chips such as the i5-1235U. Requirement pages word this differently, so check the exact wording with your department.
