Huh, the benchmarks are similar, you're right! Very interesting, and the Dell's CPU has a suspiciously low base clock, too.
It'd be interesting to see some numbers on the sustained performance from both of those and I couldn't find any benchmark that measures this kind of performance.
I'm concerned because I know from experience that the 12-inch Macbook 2016 is horrible for anything serious while the contemporary Dell XPS 13 9350 is very versatile. For me the Macbook stayed at 800 MHz most of the time, which made it unusable, while the Dell maintained at least a 2 GHz clock. Those laptops, too, show very similar performance numbers in Geekbench -

Which means Geekbench samples those bursty clocks on the Y-series that get up for tens of seconds at most.
And while it may seem like bursty loads are okay for the average user, I'd say the reality is more complex - I routinely see my wife leaving lots of tabs open in her browser, which leads to some CPU usage, and sometimes some sites just decide they need to run heavy Javascript, Facebook for example is quite heavy. As soon as this happens, the Y series laptop would throttle down and impact other work. I saw it myself on the 12-inch Macbook, and given how Apple skimped on the cooling solution for the 2018 Air, I think the 2020 model may be prone to this as well.
- artimaeis 7y agoI definitely wish there was someone out there publishing like SPEC[1] test differences across various laptops -- would make for much more meaningful comparison than Geekbench scores, but that's the real advantage of Geekbench right now is that it's pretty easy to find samples across nearly every line of computer. For what it's worth, the CPUs in those 12-inch Macbooks were pretty terrible. The base models were equipped with the M-series 4.5W chips. They had options for a couple of 7.5W chips, but even they didn't hold up in performance due to the lack of forced cooling on the 12-inch. I think 2017 is the last year they made them, and even its Geekbench score shows how underpowered it was: https://browser.geekbench.com/macs/423 https://browser.geekbench.com/macs/423 I'm still definitely looking forward to seeing how the cooling solution holds up on the 2020 Air.
