Speed test pits six generations of Windows against each other — Windows 11 placed dead last across most benchmarks, 8.1 emerges as unexpected winner in this unscientific comparison

Windows 11 gets a bad rep in the community because of its higher baseline overhead, stringent hardware requirements, UI regressions, and more – not to mention the forced Microsoft hooks that keep getting worse by the day. Moreover, when placed in a rather unscientific test by TrigrZolt, comparing six different generations of Windows with each other, it placed dead last in pretty much every individual test, though the situation is a bit more nuanced.

Six Lenovo ThinkPad X220 laptops were used in the test, featuring a Core i5-2520M CPU and 8GB of RAM, with a 256GB hard drive — running the latest versions of Windows XP, Windows Vista, Windows 7, Windows 8.1, Windows 10, and Windows 11. That setup alone should tell you how the methodology employed here is skewed toward favoring older software. Windows 11 isn’t even officially supported on these components.

Regardless, the experiment begins with a startup test, where Windows 8.1 booted up the quickest, while Windows 11 was the slowest. Both of these versions (and Windows 10) have Fast Boot capability that older Windows editions lack. In the video, we also see that Windows 11 struggles to load the taskbar for a bit, an infamous quirk of the OS that’s been heavily scrutinized ever since launch.

Then comes the storage test, where it’s Windows XP that takes the cake, with only 18.9GB of space taken up for all the apps installed. The same number of programs, along with Windows itself, took 37.3GB of hard drive real estate on Windows 11, so there’s definitely a lot of extras there. But Windows 11 actually came third here, behind Windows Vista, at 37.8GB, and the revered Windows 7, at a whopping 44.6GB.

Next up is RAM management where Windows XP is the winner once again, consuming only 0.8GB of system memory at idle, while Windows 11’s appetite grew to 3.3GB on average; it jumped to 3.7GB at one point. This is because of the added resources the OS loads in the background, including persistent telemetry.

Older hardware with less RAM, therefore, will be more susceptible to sluggishness on Windows 11. Keep in mind, TrigrZolt is also running a system with a hard drive, which are outdated at this point regardless of your operating system loyalties. Any modern system with a decent CPU and NVMe SSD will likely mask over the general inefficiency Windows 11 shows, plus options like debloat tools and Xbox FSE can further help here.

Now we move on to the second part of the RAM management test, where the YouTuber loaded as many browser tabs as possible before the memory hits 5GB of utilization. Since Firefox and Chrome don’t load webpages properly anymore on archaic Windows versions, a more widely-compatible browser called Supermium was used across all devices.

Once again, Windows 11 places dead last here, only being able to load a measly 49 tabs. Compare that to the insane 252 tabs Windows 8.1 was able to load. Even the older Windows XP managed 50 tabs, and that’s because it kept crashing past that number because of its paging file failing to keep up, not because it had hit the 5GB memory ceiling.

Our fourth test is for battery life and, of course, Windows 11 died first here, while Windows XP walked away with the best endurance. Though, the delta between all the devices was only about two minutes so it won’t make a difference in real-world usage. All the laptops had 100% battery health, too, and the same program was run to drain them as quickly as possible.

Moving on, exporting an audio file in Audacity once again put Windows 11 at fifth place, only ahead of Windows Vista which was experiencing an unusual delay, otherwise all laptops finished around the same time. The same fate follows Windows 11 when it came to rendering a video, finishing in last, with Windows 10 taking first place. Here, Windows XP and Vista couldn’t load the OpenShot Video Editor that was used, so they were disqualified.
