tl;dr - Around 99.5% of Firefox Desktop clients on release channel represented by (a 20% sample of) pings submitted by on January 21, 2016 had "hasSSE2" detected.
Here's the analysis and results on github. Please feel free to check my work: https://gist.github.com/chutten/4959c873d7fbbec0785a Keep in mind we cannot prove a negative from this. I cannot state that those pings without hasSSE2 correspond to clients that don't have SSE2 support on their machines. So I tried (and failed, see bottom section of that gist) to keep analysis and discussion centred on the "hasSSE" population alone. :chutten On Fri, Jan 29, 2016 at 2:44 PM, Mike Hoye <mh...@mozilla.com> wrote: > On 2016-01-29 2:05 PM, Cameron Kaiser wrote: > >> On 1/29/16 9:43 AM, Ashley Gullen wrote: >> >>> FWIW, the Steam Hardware Survey says 99.99% of users have SSE2 (under >>> "other settings"): http://store.steampowered.com/hwsurvey >>> >> >> For that to be valid, one must assume that the population of Firefox >> users and Steam users are sufficiently similar.
