No, people should be banned for posting pure bullshit over and over again. And sometimes that happens, but as the mods write regularly they are not the babysitters here.So you're saying people from XboxGAF should be ban for saying PS5 is RDNA 1.5 or not a true RDNA 2?
Yes, some people are spreading FUD the whole time. You can always ignore comments like "wait for the date xyz than you will see". Those people just don't have any more knowledge they are just guessing and hoping, and sometimes they get it somehow right (like it is always if you spreading constant FUD, at some point you might actually spread something that really happens) but that is just luck, but they will always remind you that they were right once

Back to the topic.
Sony has just a different way in the chip. They might not have every feature and if this is so, they have their reasons (so they think they didn't need it, they couldn't get it because of patents, ....). For all we know is, that MS might just have a spec nearer to the final RDNA2 chip. If that is good or bad, we just don't know and we can only guess.
What is really funny is, that there are now threads that Sony has VRS and Mesh shaders (under different names) but in the past few weeks/month, the same folks wanted to tell us how unimportant those features are.
