How is Sony going to implement 8GBs GDDR5 in PS4? *spawn

[Wynix]

Samsung has 4Gbit GDDR5 too, and theirs has been in mass production since last year.

The "28, 03, 04" speed grades mean 7Gbps, 6Gbps and 5Gbps, respectively.

Yeah that was posted a few pages back, along with the Hynix pdf.

So, if you look at those numbers, they appear to be saying 2GB of GDDR5 at 4GHz on a 256bit bus is 8.7W, right? PS4 having 8GB at 5.5GHz with the same number, assuming linear scaling with clock speed is 8.7*4 =34.8W and then 4/5.5= .7272 and 34.8/0.7272 is almost 48W. Of course clock scaling usually isn't linear...

Are you sure it is 2GB of RAM? It says "40nm 2Gb GDDR5", I assumed they are talking about the density. Yet how can they quote a wattage without knowing how many chips?
