Intel is now the same ... Their 10nm being what it was, was a unique selling point and being fact-based about specs is just the same.
I want to chime in on this. This is so very untrue. The process integration is more organic than just which nodes they use.
Intel did develop 14nm to the point where power consumption was down 50%. However, the genuinity you mention is not just a 'performance and numbers' speak.
I am not EE and not attune to the stuff, but there is a p/w chart that take on the challenges of SRAM by comparing cell transistor count against power consumption. I forgot which is 5-6-7T, or 8T for that matter, but if you notice the density cost, there are some efficiency measures that just aren't possible with a fixed transistor budget. The power gradient makes large SRAM banks unavailable with a former process node. That is just the way it is.
What AMD did was to enhance the pallette of tools their designers could use. They are not magicians.
Just because one is 8T and the other is 5T does not negate just how crazy that is to be able to compete on the technologic front and the performance front on a relegated node. People - don't take it for granted. These people don't just tape out better, or worse layouts. There is no default set like ARM provides.
It is like Caesar 3. You just have to intersperse 'just enough' desirability(Tr/mm²) venues. Just how many years do they have to deliberate before an initial design to its tape-out & engineering sample testing again?
PS: no blunder in a 100,000 workforce company on a 7 years long project is not a failure.
Failure is if it no longer clocks as high. Heat on the other hand, is a quite natural when you are spacing the design layout closer than before.
