How is it a plus to have to wait 18 months to get performance rather than getting it on day 1?
You didn't wait for anything, both were almost equal, you only waited 18 months to get the full ~+23% performance gained by incremental updates over the 18 month period.
If you can't work out -2% day 1 performance or 98% day 1 performance(non optimised driver) V 100% day 1 performance(full optimised driver)
= 'Almost equal performance delta' then honestly you shouldn't be getting into conversations you can't comprehend and/or being deliberately obtuse, trolling.
Who would seriously choose to wait 18 months to get the performance?
Again as above impossible to wait when both start almost equal
How is saying it's better to wait 18 months rather than get performance day 1 not showing bias to the company that takes 18 months?
If you increase performance from ~-2% to ~+25% over the space of 18 months then there is no bias it's merit unless you simply refuse to give said merit because it's AMD.
If it were Nvidia doing it I can't imagine the same people would be spinning it as a positive.
If Nvidia increase performance from ~-2% to ~+25% over 18 months(like I already stated above by swapping the vendors), it would be the same outcome and cause it's Nv they would market it at least twice as good as AMD know how to, and of course it should be applauded, I certainly would and the majority would also, you'd be laughing at anyone not agreeing it was anything but positive achievement wouldn't you?
If the 1080 was released with 1070 performance and had only recently gotten to the level it's at now I don't think that would be better than it releasing with 1080 performance and not gaining too much. But here we're constantly told that when AMD do this that it's a good thing. How is that not AMD bias?
IF is irrelevant, nothing remotely happened the way you are trying to flip it, you're making it up as you go along to try and stay valid so there's no point trying to add some kind of bias validity into it.
You are trying to suggest a £450 290 went head to head with a £300 970 and didn't get to the £450 performance for 18 months, it didn't happen, if it did then no one in their right mind would be saying anything but it's rubbish.
However using your 1080 v 1070 scenario but pricing them both the same@£400 is exactly what's been happening except you bought the under performing 1080
for 1070 money that didn't perform to it's peak for 18 months, but it only cost 1070 money so you can only gain you can't possibly lose-it's impossible, you would have to be thick beyond comprehension to state otherwise.
And yes I'd take that scenario every single time as it costs the same money at the same performance delta from day 1.
