3a) A lot of rumors and leaked documents have hinted that MS was intending on using DDR4. This was supposed to be launched late late 2012 but was delayed due to less growth in the desktop market and more growth in the mobile market which has no need for DDR4. DDR4 is not as fast as GDDR5 but it can be close (and better with EDRAM/ESRAM), and it would dropped in price dramatically over the years as it entered the PC market (In contrast DDR3 prices should continue to rise like DDR2 did when it was replaced). |
Mobile Market does have a need for DDR4, it uses less power.
Also, Initially, like DDR and DDR2 that came before it, DDR4 won't be that much of a leap over DDR3, heck you can already get DDR3 that will clock up over 3Ghz.
Won't be untill a few years after launch that speeds will climb above DDR3's ceiling.
As for DDR4 vs GDDR5, lol. - Enough said, GDDR5 will still have a massive bandwidth advantage and won't be replaced untill GDDR6.
