30 billion on a chip now. 7 Nm in production, 5 Nm next year or so.

Originally posted by FabianFnasI think laps use generally 15 nm size transistors, giving several billion on a chip. go to 5 nm and you get something like 8 times as many, it makes for more complex CPU/graphics and so forth or for the same number of devices, less power so more battery life.
7 nm doesn't tell me much.
What do we have now? Like 10 nm?
What do I have in my laptop?

You could for instance, put 8 or so CPU's in one chip or more.
Now you can get 4 but that co ...[text shortened]... t with these new 5 nm chips coming out in a couple years, Exa bit computers won't be far behind.

It couldn't hold an assembler in memory so I had to program the thing in machine code hexadecimally. Learnt a lot. Those were the days!
Originally posted by DeepThoughtIt was a Nascom-2, bought as a do-it-yourself construction kit. Soldered for a week, and it was quite a feeling when I put in the plug - and it failed. However, I found the error and corrected it. Then it worked fine with a staggering speed!

I think, and it is easy for me to be mistaken about this, that the channel width limits the frequency the processor can run at, so as well as increasing the number of transistors that can fit on a die they can make its clock run faster as well.
Originally posted by FabianFnasWell, we were given a REAL gem. A genuine IBM computer, a FOUR megahertz 8080 WITH co-processor. A real screamer! Funny, I remember, it belonged to a friend, a college prof, and he got something better (how could you get better than THAT🙂
