The Steam Hardware and Software survey uses the Steam client to find out what sort of hardware and software is used among the gamers using Steam. The survey brings with it an interesting, and somewhat predictable, view of the gaming PC landscape. The short version of the results is that NVIDIA and Intel dominate the market share.
Let's start with CPUs. Unsurprisingly, Intel dominates the gaming landscape as far as CPUs are concerned. Intel has 72% of the PCs that participated in the hardware survey. Just about half of Steam gamers have a dual-core CPU and 7.5% have a single core. Fewer than 4% have more than four cores and 38% are running quads.
On the GPU front, NVIDIA commands 47% of the surveyed computers. 36% of users are running an AMD Radeon GPU and 11% of users are stuck running Intel's integrated graphics processor. The NVIDIA GTX 560 is the most popular GPU of the DX11 generation and commands 10% of the computers surveyed. The GTX 460 is the next highest at just under 6%. The 5770, the most popular Radeon, is sitting at just under 5%.
