Windows 11's NEW CPU Requirements (Why You Shouldn't Care)

Is it a big deal though? 🤔

Ah yes, 0:03 "Mac'osoft", the fusion between Mac and Microsoft

In 1989 I worked on a Boeing 737-300 Communications Bus in Michigan.
I was hired to increase traffic flow rate.
As the project was wrapping up, we received a notice
from the bus controller manufacturer that
if more than 22 bits of a 32 bit data word were 1,
the controller would glitch and lose data.
I NEEDED THE POPCNT instruction.
But it was not in the Z8002 processor at the time.

Excellent Info.

No one with a 2006 procesor would try to install windows 11 🤔 they would probably chill with 7 or 10

I understand the rationale behind Windows dropping support for various processors as they aim to streamline and remove legacy code from the operating system. The old legacy code interfacing with newer versions necessitates this decision. However, my concern lies in the lack of transparency. It would be more honest to clearly communicate the reasons instead of using explanations like security measures.

As you said for Cryptography, it makes the task very very fast as it is directly running on hard ware. While the other option might be some kind of emulation or program which might make such a task slower. Hamming code is used to check if data is tampered either intentionally or unintentionally, and having dedicated hardware for such a task is actually good as far as my knowledge goes.

Edit:- Now that I think of, bit locker might rely heavily on it, also all network packets verification might be done with it but not sure

Apparently there are other programs that had these requirements that have been patches with a software version of this instruction.

Popcount is something that you can implement in code. In fact, some code optimizers will detect if you try to write your own code to implement Popcount and replace it with the POPCNT CPU instruction.

I can rest easy knowing that my retired 1st gen i7 960 just barely makes the cut for a version of Windows it will never see. That particular computer was made for 7 and I wouldn't have it any other way.

Thing is PopCnt is so old that newer CPUs since SSE4.2 was introduced into x64 processors STILL won't have TMP support, nor SecureBoot. You'd have to be sporting an old 32bit CPU like an Athlon XP or a Pentium 4 which a 64bit version of Windows wouldn't run on anyway, and Windows 11 doesn't exist as a 32bit OS.

There are a lot of people in the third world (or in very rural places with low access to technology in the first world) running very old devices because that's what they have access to or can afford. I worry that they're *not* going to change to Linux and will just continue running whatever Windows they can past the expiration date.

I don't really fault Microsoft for implementing changes that affect stuff older than Nehalem, I mean that's ancient, but it's still unfortunate any time this comes up. It's good that Linux is there as an option, but I really wish Microsoft would just make some kind of stripped down version of Windows for older devices so that they can at least get minimal web functionality and updates. I guess it's not really in their business strategy, though.

[xXx_Regulus_xXx]

what does windows 11 *do* that warrants better hardware, anyway? I still do the same things I did several versions ago so I'm not sure what the value add is for me.

Just to clarify, as Thio talks about SSE 4 and begin to talk about them at 1:57, the first Intel CPUs that supported SSE 4 (by means of SSE 4.1) were the Penryn based, known by their market name Intel Core 2. The SSE 4.2 which implements the PopCnt feature required by the Windows 11 24H2 update is indeed the Nehalem, as he states in the video.

As a Windows 10 user who’s not upgrading ever: “Oh no… Anyways”

[hentosama]

i5 4960k running latest w11 here, still chugging along!

[Munenushi]

i would not have been able to pronounce the cpu feature "POPCNT", as often as you have, without saying the 'bad' word that the abbreviation is making me think in my head. you are a stronger man than i am. kudos, and kudos for informative vid!

What's interesting is that the Hackintosh community was confronted with the same problem ages ago. They wrote an SSE4.2 emulator and had the kernel trap said instructions to get newer MacOS versions working on SSE4.1 Macs.

i love that he put the windows 10 logo instead of the windows 11 logo in the thumbnail

[benhaze]

I still can't believe that my i7-4770 is not compatible with Windows 11. It was a high end CPU at that time...

Wow. Not a black V-neck. Congrats 🎉

Joe not wearing a black V-neck makes me feel like I'm in an alternate universe.

The problem I have is it’s a slow rolling snowball, people don’t realize it yet but windows has been doing more and more to limit what people can and can’t do.

The amount they changed without warning “should” be concerning but for some reason it’s just not.

Microsoft are even turning windows into even worse spyware and putting ad placements in the start menu.

What’s worse is a lot of people still feel forced to use windows either because they don’t know how to use Linux or because there is no better alternative yet.

Proper subtitles, wahoo! Please never stop providing those :D
