The transition between PC memory standards has always relied on changes in PC platforms for effectiveness. For example, the LGA 775 saw transition between two standards, the i915 MCH supported DDR and DDR2 memory, i925 onwards it became mandatory for people to use DDR2 memory as the platform required it. In came DDR3 and it became optional for users to choose it over DDR2. Even now, there is only a gradual transit between DDR2 and DDR3. With Nehalem however, it will become mandatory to use DDR3 memory, both with the LGA 1366 and LGA 1160 socket motherboards in either two or three channel configurations.
Qimonda has already chalked out plans for a smooth transition to DDR4 PC memory. According to Qimonda's development plan, DDR4 would be out by 2012. The memory standard will operate at (DDR) frequencies as high as 2,133 MHz at an approximate voltage of 1.2 V and by 2013, we could be seeing 2,667 MHz memory at 1.0 V, a phase during which there's a transition between the current DDR3 and future DDR4 PC memory standards.

well . . . technically, there are slight differences between SYS DRAM and GPU DRAM. it's nothing dramatic, really, but the differences equate to GDRAM being developed for use and access by GPUs; they respond faster, tend to be more efficient and are capable of running at much faster speeds than their equivalent SYS DRAM components. The biggest difference between the two varieties, is that GDDR# can turn on a MEM bank and read from it within the same clock cycle, whereas SYS DDR# can't.
Otherwise GDDR# operates at a theorhetical level the same as DDR#.
I understand there are differences. I don't know much into the details. I was just saying to the average consumer. In a year they will be looking at GPUs running on DDR5 and still be sitting with DDR3 as the big thing in their systems. Don't we already have enough confusion out their for them. LoL
