This! You can see a lot of discrepancies in testing and wildly differing results from various review outlets. On top of that the gaming performance does not at all match the synthetic or productivity performance and even the same games from reviewer to reviewer. For instance in Joker's test of DX11 BF1 he shows an OCed 1700 beating the Intel 7700K even, but when you look at DX12 BF1 in other tests, Ryzen is seriously behind, like what's going on?
HardwareUnboxed for instance admit their sample is underperforming where it should be compared to other tests, but still notice a less intermittent stutter when playing games with Ryzen compared to 7700K.
We also know of a couple of issues some reviewers ran into and others didn't. Like XFR not working for some, memory XMP not working for some, window's balanced profile not playing nice with Ryzen (AMD apparently submitted a driver for this we should be seeing come down the pike at some point).
At this point I really want to see motherboard side by side reviews and see if some of these issues can be uncovered, and traced down to BIOS issues.
I am really not convinced Ryzen is as slow in some games as some of the reviews show.
At the end of the day.. Ryzen is a big launch. A whole new architecture on a brand new platform, on a brand new process. It's also the first competitive CPU AMD has made in a decade.. so it was always a given there were going to be teething pains with this baby.
