If MS switches to GDDR5 now, did Sony make a silly mistake?

  i find it hard to understand why no manufacturer has used GDDR5 for main memory yet.

Maybe because the memory interface in all cpus (excluding exotic designs) is a ddr3 memory interface?

Well thanks, capt. obvious. That's because GDDR5 is a handicap for CPU.

I have no clue as to your answer being something that should be considered "clever" but obviously you have not the slightest clues as to what my answer means and how processors talk to memory.
