RA Tech has a video about it. Watch and listen to the benchmarks running. In Shadow of the Tomb Raider, Ivy Bridge i5 had audio issues, and failed to render assets and NPCs. It will spit out good numbers at the end though. RA was playing games and using discord on windows 10 (you know how many gamers actually use their gaming PCs) and experiencing audio issues on those old similarly priced Intel CPUs, the FX was fine. That said, there were and still are games where the better single thread IPC of those i3 and i5 Intel CPUs makes a positive difference to playability vs FX, which IMO is all that matters, the gaming experience. Not bigger bar better on charts. Most test suites were automated and or unattended. And certainly not jumping in 64p MP and playing a few rounds then reporting back. Instead testing early in games which is usually less CPU taxing. In game test runs, when not using canned, were and often still are, under a minute each, often under 30 seconds.
