1. People don't want Intel to introduce either DRAM L cache on CPU or DRAM-on-die because they are afraid of change
2. Remember how physics cards were external(it's own card
) well now it's adopted into the chip itself, before that there were audio cards, now it's integrated into mobos, also network controllers and cards, you get the drift. So integration is the way of advancement, if you don't like it go use a 486 or P-I.
3. There are two directions Intel is likely to go in the future, 1. optical processing, 2. further integration by enlarging the die to double-tripple to fit DRAM+miscellenious improvements that benefit from integration. Intel could also follow #2, and then when optical processing matures do #1.
Note: Integration of 4-16 CPUs, plus graphic processors, plus DRAM = a lot of heat, but because the die is now 2-3 times bigger, the cooling becomes easier with greater surface area. Remember, they shrink the size in order to speed up latency of wires\\paths in the processor and reduce heat. The overall speed and latency is many times smaller inside the integrated CPU/Graphics/DRAM and 2-3 times bigger in size compared to external DRAM, video card and else, the value of integration is evident.Edited by dumont - 6/19/08 at 4:08pm
