You may have noticed something interesting when visiting AMD’s Radeon driver download page. 31-bit (x86) versions of it’s latest drivers simply don’t exist. It turns out AMD has officially discontinued driver support for 32-bit operating systems. This includes Windows 10, 8, and 7, Linux OS distributions such as Debian, Ubuntu, RHEL, and CentOS.
This really does not come at too much of a surprise as 32-bit operating systems have been out the door for a while now. Mainly due to the lack of memory support as x86 operating systems are limited to only 4GB of RAM. The lack of surprise also comes in the wake of NVIDIA which stopped supporting 32-bit operating systems last year. Only a small percentage of gamers will likely be affected. According to Valve’s Steam hardware survey, only a small percentage of Windows 7 and Windows 8.1 users will be affected (1.57% of Windows 7, and 0.06% of Windows 8.1 users)
The latest 32-bit Radeon Driver released by AMD is Adrenalin 18.9.3. So if you’re still running a 32-bit OS, that’s the last update you’ll receive. If you are affected by this, GND-Tech highly recommends upgrading your operating system to a more modern OS version and architecture. You’ll reap the benefits of added support as well as increased system security.
