AMD Preparing to Drop 32-bit Support for Radeon Drivers?
Is AMD planning to retire driver support for 32-bit Windows? A bulk of the company's Radeon R9 and Fury series GPUs feature 4 GB or more of video memory, and 64-bit Windows users making up the overwhelming majority, the company has begun steering users away from using 32-bit Windows altogether. We got whiff of this when we visited AMD's Drivers + Download Center on the company website, and tried clicking on the "32-bit" links of some of its Windows 10 and Windows 8.1 drivers, which redirected to an ominously-worded AMD knowledge-base article (Article #GPU-622).

A system running Microsoft Windows 10 64 Bit can take full advantage of the advanced visual and performance features of these graphics cards. However, AMD also provides 64 Bit drivers for Microsoft Windows 8.1 and Microsoft Windows 7 to accomodate those users who choose to use an older Microsoft Operating System.The knowledge-base article has no links for the drivers users are looking for. A little URL guessing later, we did manage to find 32-bit versions of Radeon Software 16.3.2, but that's something ordinary users will not be able to make. According to the download page, AMD's recently launched Radeon Pro Duo already completely lacks 32-bit Windows support, and the company is only providing 64-bit drivers. This move could prove useful for AMD as it frees up resources inside the driver team.

Also, it isn't 0.1-0.2% of the market. Go over to the Steam hardware survey. 32-bit OSes account for ~12% of the computers surveyed. And that is among gamers, who are less likely than the standard user to be using 32-bit. So I don't think the number of people using 32-bit is as small as you think.
And how many of that 12% will go for a Zen APU and keep that 32bit windows version?
I mean, you just bought a new PC with a probably and hopefully not very cheap Zen APU, a new motherboard and DDR4 RAM. Windows key is universal for both 32bit and 64bit versions and Microsoft is giving the option to upgrade from a 32bit version of Windows, to 64bit Windows 10. Are you really staying with a 32bit operating system?
There's a crap load of 32-Bit OS's out including Windows 10, 7, 8, Vista etc., the silly part of this is the very fact Windows 10 comes in 32-Bit. That is laughable at best, especially when you need MIN 8GB of Ram to run it properly.
You need a 64bit CPU to run this systems anyway (well Windows 8 and later), at least on a Desktop sockets because they require the NX bit to be present.
Thus you need a Pentium 4 with an E-Stepping Prescott core - wich also supports AMD64 in some LGA775 versions. I don't have any information on the S478 ones though...
So the 32bit versions of those are useless for desktop systems.
They are only needed for those shitty 32bit only ATOMs (up to 2000 series, the 3000 series is 64bit AFAIR).
Windows 10 ran pretty well on my 7y/o PC with 4 GB of RAM than ran better than Windows 8[.1] that ran better than Windows 7.

it must be getting harder to code for the 32bit users. the Dual GPU boards I honestly feel might be held back in 32bit environments
-no 16-bit application support on 64-bit Windows (processors support it but Microsoft does not)
-all drivers must be 64-bit (this is only an issue if the hardware was designed for Windows XP or older; Windows Vista and newer WHQL required 32-bit and 64-bit drivers)
-64-bit binaries tend to be about 20% larger than 32-bit binaries because of the increased address length.
Dinosaur printers, hardware, and software should be relegated to legacy hardware. For example, set up a printer server on the legacy machine so that 64-bit machines can print via a 32-bit server to the legacy printer. The bulk of machines everywhere should be migrating to 64-bit.
I think a lot of businesses/IT stick to 32-bit because they don't want to tackle the challenges (assuming there are any) associated with changing to 64-bit. You know, the whole "don't fix it if it isn't broke" montra. They won't switch until Microsoft gives them no choice.
Outside of businesses/IT as well as tablets, 32-bit is rare. Even the cheap $400 laptops these days ship with 64-bit.
Windows emulates NX bit in software (DEP) if the hardware doesn't support it.
It translates 32-bit calls to 64-bit on the fly. 16-bit calls aren't accepted.
It really doesn't behave any differently than how Windows 95 (32-bit) handled Windows 3.x (16-bit) executables.

You'd be surprised how many games came out recently run on 64-bit given the opportunity.
Even to this day, if a game does not use that flag they can't use 4GB of ram - and if they do, they'll crash under XP/32 bit OS's if they pass 2GB so its a proper catch 22.
Companies are beginning the death of 32 bit OS's, which is not the same thing AT ALL as killing 32 bit games, software or programs.
