AMD is right... DDR3 is already old and now it is starting to become expensive.

GDDR5 (and DDR4 after launch) will be even more cheaper when the mass production for APU, console and GPUs started.

And remember the "latency" is more related to the memory controller than the memory itself... the memory controller in GPU that have a high latency and not the GDDR5.

ethomaz, this is nothing to do with tech and everything to do with cash.

Would DDR4/GDDR5 be faster? Yes. Can they be done, by AMD, in 2013? No!
