Update: Upon further review, it appears the benchmark results presented in the video are inaccurate. The tests performed on Windows 10 were done with the "Recommended" performance mode, while the Windows 11 tests were done on "High Performance." This explains the disparity in scores. While it appears there might be performance improvements coming with Windows 11, the benchmarks in this article are not an accurate representation of that. The original story has been updated to reflect these changes.

In case you didn't want to wait for Microsoft to unveil it on June 24, here's the scoop: Windows 11 is out in the wild via a leaked build. One Youtuber, Ben Anonymous, has performed benchmarks comparing Windows 10 and Windows 11, but a disparity in performance modes makes the data a wash in regards to any perceived improvements.

It's a rather long video that goes into the nitty-gritty on a whole bunch of items, ranging from 3DMark and Geekbench 5 results to basic boot speed comparisons. However, it later came out that the Windows 10 tests were performed in the "Recommended" performance mode while Windows 11 was in "High Performance" mode. That makes any comparison virtually worthless, but the tests are still interesting because they're some of the first we've seen with Windows 11.

Here are some of the highlights.

Windows 11 Pro Build 21996.1 booted 18.75% faster than Windows 10 Pro Build 19043 (13 seconds versus 16 seconds).

Windows 10 got a 3DMark score of 6,872 at 4.8GHz, hitting 92 degrees celsius on the CPU while reaching 76 degrees celsius on the GPU. Windows 11 got a score of 7,613 at 4.9 GHz. It hit 99 degrees celsius on the CPU, 78 degrees celsius on the GPU.

CrystalDiskMark, which measures SSD speed, gave these results:

  • Windows 10: Read speed of 2,930 MB/s, write speed of 3,189 MB/s
  • Windows 11: Read speed of 3,448 MB/s, write speed of 3,336 MB/s

And here's what BenAnonymous got during his Geekbench 5 testing:

  • Windows 10 managed a single-core score of 1,138, a multi-core score of 6,284, at 4.8GHz at 97 degrees celsius on its CPU
  • Windows 11 boasts a single-core score of 1,251, a multi-core score of 7,444, at 4.9GHz at 93 degrees celsius on its CPU

While comparisons based on this video can't be done because of the performance mode disparity, it still appears we'll see some improvements with Windows 11. Hot Hardware recently performed some comparison benchmarks that allude to this. However, it's worth noting that all of these tests are being done on a leaked build, and we don't know how old it is. In other words, take anything you see out of this build with a massive grain of salt.

  • Basically they're bringing back Widgets from Windows 7. Won't it affect the performance or drain more juice from portable devices?
  • Maybe the widgets are only for NEWS AND INTEREST thingy
  • Hope not, I can see the use for live widgets on portable devices like phones. Windows Phone resurrected!
  • Windows Phone is dead.
  • @CocoPizza_2000 😱😱😱 Nooooooooooooooooooooooo /sarcasm 😁
  • Actually there are two new widget components on Windows. One is in preview in the new Edge browser, and the other is News and Interests. The old widget platform in Windows 7 was built on Internet Explorer's engine.
  • Is there any relation to these "Fluid elements" we are seeing being rolled out in Office and Teams/Whiteboard?
  • I don't know, but that would be cool!
  • I am so excited !!!
  • Now this is great stuff. It seems like Microsoft has managed to trim the fat off of Windows 11 somehow.
  • Seems faster. (No one beat me to this? Come one!)
  • lol, it's been a very long week, but good catch
  • I forgot what this is. I know it is a windows central meme. Can someone please remind me??
  • Every time there was a major Windows update, someone would say in the comments, "Huh, it seems faster" but it was usually not really. That was consistently funny.
  • I think it was "seems snappier". Those were the days :)
  • yeah especially when everyone was talking about WP8 and WP8.1 updates 😂
  • I'm pretty sure it actually became a meme around the time Microsoft was developing the Facebook client app for Windows Phone. With each update, we would have an article on then Windows Phone Central and the first comments would be "seems faster" whether or not that was actually the case.
  • Wen in India? That was another classic.
  • Leaked ISO is already hidden in some websites, don't know it's available on Google index now. We'll probably get the release date in 5 days.
  • Yes, wen in India!
  • Rofl nice one. The days of Windows Phone 7 to 8 for me.
  • I still don't understand why live tiles were never given the functionality to behave like widgets
  • I'm often amazed at how many Android widgets don't launch the app, or do so only when you tap in some awkward place, and it launches to some too specific page.
  • @Andrew G1 ikr... I use Sailfish X which runs droid apps in a container and it's worse there... the lack of optimisation in android apps at first literally made my skin crawl. Thankfully Jolla are coding around the worst of these problems so that makes it bearable. The poor and shoddy optimisations of the apps is in my view the primary reason Android phones have to have beefier and more beefier specs. Previously it was the apps and the Android o/s itself - at least now the Android O/S has really decent optimisations on some phones. The caveat is the forced obsolescence in order to sell the latest and "greatest" flagship every 2 to 3 years.
  • original idea for live tiles is to deliver like widget functionality with minimum battery consumption.
  • I think this guy has the same leaked version that everyone else does.
  • It's been confirmed md5 hash check was done between the "leak" and the one that was sent out to insiders accidently a few weeks ago. It's the same version the file name has changed slightly for some but it'd the same data.
  • I'll be interested to see if it also boost ARM performance, that could be important for any 8cx Gen3 designs.
  • Well benchmark will be interesting to see once Cortana back in Windows 11. But can't deny the excitement to see polished UI with better performance.
  • Since when is a 10% increase in graphics performance a "huge" margin? Significant, maybe
  • I'm hopeful this is true, but skeptical, especially the drive tests. Even if 11 is better and faster than 10, the drive test should be consistent across both. I suspect the same is true for other hardware tests. That makes me think this may just be BS. I hope to be wrong.
  • Looks like it's time for me to buy a new laptop to replace the old ASUS I got with the brand-spankin' new Windows 8.0 (seems like forever ago). Something with Tiger Lake... (Sure hope Microsoft adds back the Microsoft Hearts game, too.)
  • Interesting, I'll wait for the actual launch, reviews and tests based on the official release iso. Right now, for me it's filed under "it's interesting but nothing to see here" lol. As I am not getting carried away by the hype train haha...
  • I am just excited for the event at this moment
    Can't wait anymore XD
  • Well, maybe the latest update to the article will calm ya down abit lol. In short - “nothing to see here” roflmao.
    I don't blame Robert for getting caught up in the hype train as plenty of the technosphere did haha.
  • Can't wait to use it unactivated
  • I used the upgrade path from Windows 10 to Windows 11 and it is wayyy snappier. (I used the setup file in the iso and kept files and apps.) The “modern” apps open instantly.
  • Wow, if that's true, that is exciting, when was the last time a Windows release can be considered exciting I can't remember.
  • It would be great if there was an operating system that was only available for internet browsing. It'd be smaller. For example, it would be 1 GB volume. The operating system is just for the Internet. I would buy such an operating system immediately. It's an operating system built just for internet browsing.
  • The closest would be chrome OS, not really worth building an OS just for browsing.
  • HP Quickweb is?
  • build your own, there are free opensource OS kernel and internet browser .
  • Why? What would be the point? Do you have a 1GB PC that you need to use?
  • How can I logout from this forum? there is no log out buttom ffs
  • You can logout from within the hamburger menu.
  • I realize this is totally off topic, but why does everyone call that the "hamburger menu"? It is 3 lines. It looks nothing like a hamburger. Or a menu. Why not call it the pancake menu? Because it looks nothing like a pancake menu either. It is 3 lines. Why not call it the Egg McMuffin menu? Because it looks nothing like an Egg McMuffin menu either. It is 3 lines. I just call it the Options button.
  • Why the whining? "Options button" is far too vague a term because there are plenty of options buttons around, possibly even on the same page, that are nothing like that. It's fairly obvious that the three lines are, in this context, considered to represent the bun and patty of a hamburger. That it doesn't look like an actual hamburger is irrelevant. What matters most is that, when you use that term, pretty much everyone knows what you're talking about. It's a communication tool and it fulfils its purpose very well. Get over it. And go and click on some radio buttons while you're at it.
  • Awww... What a bummer. And I was hoping Windows 11 would actually be awesome.
  • Isn't Windows 11 using the latest Windows 10 insiders version? which would mean: Windows *10* to get a performance boost. Until now there is nothing indicating that Windows 11 internals is nothing more than the same Windows 10 plus extra programs like: one for a start menu, a program to simulate rounded corners, etc. The same leaked build is used justify why is deserves a next major version, but at the same time ignore the negative parts saying that is an early build. Well, it is MS.. never underestimate their capacity to deliver buggy software and bad hardware. Many articles praising Windows 11 based on a leaked build are just ruining the unannounced versions of Windows, it has become "Windows 11 is a lot more" vs "Is just Windows 10 + skin" 😅
  • Windows improving performance on existing hardware.
    Lol
  • "X DESTROYS Y!" <shocked face> <in the comments> "LOL stupid Y sucks!" Clickbait's clickbait. It's never going away. It works because enough adults with purchasing power and YouTube accounts still think like teenagers.
