I wonder what will happen to the CPU, especially if it’s not speeding up much anymore. Perhaps with Apple doing its own chips, the CPU will just have less and less of the work assigned to it.
- ianai 9y agoAt some point it was going to be germanium to replace silicon.
- resource0x 9y agoRemember GaAs? It was the Future in 1980.
- deepnotderp 9y agoHe's talking about germanium channel FinFETs, GaAs was intended to entirely replace silicon, which probably was never going to happen.
- Tobba_ 9y agoGaAs logic is probably happening at some point, just not yet. All improvements like that which would be incredibly expensive to develop will be held off on until all cheaper options have been exhausted. It does seem to be slowly moving though.
- woadwarrior01 9y agoGaAs is gallium arsenide, which still has applications in high frequency transistors.
- ScottBurson 9y agoGermanium could still come back: https://spectrum.ieee.org/semiconductors/materials/germanium-can-take-transistors-where-silicon-cant https://spectrum.ieee.org/semiconductors/materials/germanium...
- jeffreyrogers 9y agoThe problem is silicon is really cheap compared to germanium, so germanium only makes sense if the increased speed is worth the cost (which it probably isn't for almost all applications);
- ianai 9y agoWhat’s the cost factor? Ie why not have a UI germanium chip and silicon the rest of it?
- blueline 9y agoif someone figures out a way to bring EUV to mass production scale, we would afaik essentially have a clear path all the way to 3nm
- abritinthebay 9y agoThat’s a BIG if.
- martinpw 9y agoWhich still really isn't that much further considering how far we have come so far.
