4770 is a 4core 8 thread cpu, not a 6core
I think he meant you can get a Ryzen 6 core for £120 new which performs the same as a 4770K.
Except that the only £120 Ryzen 6 core I can find is the Ryzen 5 1600X (£130) and it holds its own against a 7700K in everything except 1080p gaming. But then Dg does seem to fixate purely on gaming performance as the all-encompassing metric, presumably because that's where Intel hold their only lead.
This forum, since the Ryzen release, is well known for having a strong AMD bias and I'm sure I am not the only one who has found it a pretty rubbish place to just come and get good information from because of pro AMD vitriol. There are one or two Intel crazies here for sure but for the vast majority of the last couple of years it's been the AMD crowd drowning out any decent debate and I find it odd that this has gone unnoticed by you. I've seen many times certain posters literally making stuff up about Ryzen even when it has been proven wrong.
