While there are plenty of differences, the most important ones are that 64-bit Windows and programs may use more RAM, that 64-bit Windows offers additional security benefits, and that 64-bit Windows and programs are usually larger. We talked about the differences of 32-bit and 64-bit versions of Windows back when Windows 7 was released. Mozilla pushed the 32-bit version of Firefox on Windows, and is just starting to change that.ĭifferences between 64-bit and 32-bit programs This has been the case for the Firefox web browser for instance. Plenty of high profile applications are either only available as 32-bit versions, or prioritize the 32-bit version over the 64-bit version. Things are different on the software side. The differences are less drastically for Windows 7 (28.82% to 5.40%) and Windows 8.1 (8.59% to 1.19%). Still, Windows 10 64-bit dominates Steam with 48.37% currently opposed to 32-bit Windows 10 with only 1.23%.

That is somewhat to be expected considering that games benefit from a lot of memory. If you look at Steam's Hardware Survey, as flawed as it is, you will notice that 64-bit dominates the chart. Microsoft itself has not released statistics about the distribution of 32-bit and 64-bit Windows systems. While Microsoft is still producing 32-bit copies of Windows 10, those are sold and deployed considerably less than 64-bit copies.

If you have bought a computer in recent years, chance is you run a 64-bit version of Windows on it.
