JEDEC finalizes DDR4 spec, coming to a PC near you in 2015

  1. Memory standards group JEDEC has published the final specifications for DDR4 SDRAM, promising more performance, reliability and efficiency than today's DDR3 parts. DDR4 touts a per-pin data rate of 1.6GT/s to 3.2GT/s (giga transfers per second), though JEDEC notes that...

  2. "The new design consumes 1.2 volts"
    A device doesn't consume volts; it consumes power (Watts). And while watts are more or less based on volts (for DC: P=U*I or Watt=Volt*Ampere; for AC or complex waveforms this becomes a bit more difficult), they're really not the same.

    It really doesn't matter. The point is it draws less power.

    The point is one can use a single supply for both processor and memory banks and maybe integrated graphics...

    Well, I think the Guest's feedback matters. I've changed the text so it reads "runs at" instead of "consumes" -- hopefully that's more accurate :).
     
  6. Guest above was totally on with power vs potential. You could run at only .5 V but draw 1 A which would be 500 mW. On the other hand you can run at 1.6 V and only use .25 A and end up with a power consumption of 400 mW. It is nice to see that the author took the reader feedback into consideration. Good on you.

    Something to look forward to, I suppose. Always nice to see progress marching on. I'm pretty happy with my computer now, so it's likely that the next time I do a full system replacement, I'll be buying myself something like 32GB of DDR4.
