stuff about how using automated design tools instantly made things worse
Example of AMD and Nvidia designs which did well
You latching onto me talking about Atom and talking about power consumption
Yet last year when Zacate was launched,both Intel and AMD were both using 40NM/45NM design processes. Yet the 45NM Atom still turned out poorer overall. The reason why the newer Atoms do better is down to the process shrink down to 32NM. You saw that with Nehalem to SB.
Zacate was a mostly a design using automated tools,just like a lot of ARM licensees like Nvidia who don't design the cores but modify parts and integrate them with their own IP.
The current AMD Zacate chips were meant to be shrunk down to 28NM,but they shelved that so they could bring Jaguar forward.
I'm not sure why the technicalities are brought in.
They won't be able to penetrate the mobile market if their APU's are using twice as much power as the Intel stuff, performance aside (I'd take the AMD stuff personally)
And it's not just the fabrication, AMD themselves have gone to some lengths to make their new tablet/netbook stuff more power efficient than their previous offerings, but as far as I'm aware, both Hondo and Ontario (And desna etc) are 40nm.
Not vastly different from when AMD stayed 40nm on GPU's and made their designs more efficient.
Because the conversation was about automated design and how it made worse CPUs. This is not the case all the time. The only reason that Atom is doing better is due to the shrink to 32NM. The 28NM AMD shrinks were shelved in favour of bringing forward Jaguar - this has been known for a VERY long time.
You know why?? Atom is being redesigned with new cores and being built on a 22NM process for late 2013. This is the big threat. Zacate is the most successful AMD CPU for years unlike their higher end stuff. So,AMD decided to spend their resources on getting 28NM Jaguar out as quickly as possible:

Jaguar is a new core,and is made to be more efficient by design. Zacate was a netbook CPU,Jaguar appears to be design with tablets in view too.
This is the SOC which will make or break AMD in the tablet market.
Moreover,Jaguar is a much more portable design. They have made it such that you can change between processes far more quickly and easily than any previous AMD design. This means they are less at the mercy of an individual fab.
