621 million transistor chip

    I thought we were on the limit for transistor density but this chip looks like it is way over that limit.

    From science daily.

    A microchip containing 1,000 independent programmable processors has been designed. The energy-efficient 'KiloCore' chip has a maximum computation rate of 1.78 trillion instructions per second and contains 621 million transistors.

    Ho hum. Modern off the shelf CPU chips routinely have over 1,000,000,000 transistors so 621,000,000 isn't particularly impressive.

    The one in my desktop has 1,400,000,000 and it's not particularly high end.

    @phinds - the chip described in the article is massively parallel, and is unique. IMO. It is fundamentally different from a GPU-like cpu as you cited. And apparently very efficient - energy consumption ~0.7W as opposed to an NVIDIA 970 which is 145W minimum. It runs on a single 6V battery.

    Agreed, but the OP was commenting on his thought that this had hit a limit in transistor density, which is what I was responding to.

    EDIT: Hm ... I see that actually I was not looking at the DENSITY of the chip, just the number of transistors so my point may be off.

    32nm technology is not as dense as it gets these days. Go here, and look to the right towards the top of the page for a table that puts 32nm in perspective.


    The big deal about the chip you referenced is the amount of parallel processing it can do - imo quite impressive.

    Millions, trillions of transistors.
    Wouldn't it be fun to scroll the circuit diagram of such a beast?

    Ah... well... maybe not ; )

    Actually, I'm pretty sure these things are built with magic ... no diagram required :smile:

    I doubt there ever was a circuit diagram. It went:

    verilog --> netlist --> gds --> chip
