Talk about contrasting results. In today's thin-and-light laptops, it is fascinating to see performance vary depending on implementation, and the Core i7-8565U in the ZenBook 15 UX533FD is certainly a mixed bag.
Single-thread performance is excellent, with the chip's 4.6GHz boost frequency giving it a clear edge over the favoured Core i7-8750H. The tables are turned in Cinebench, where the quad-core chip's results are in line with expectations, but what's happening in HandBrake? This demanding test runs for some time and puts maximum strain on the CPU, revealing how capable the laptop is at keeping to peak speeds. Our logs show that the ZenBook 15 leans heavily toward keeping cool, as all-core speed drops below 2.5GHz just a few minutes into the run.
Should the amount of throttling be cause for concern? That depends entirely on your typical workload, but it's worth pointing out that we didn't experience any meaningful slowdown during everyday use.
