Elpida Memory, Inc., Japan's leading global supplier of Dynamic Random Access Memory (DRAM), today announced that it had completed development of a high-density, high-speed, low-power consumption 50nm process 2-gigabit GDDR5 using copper interconnects (product name: EDW2032BABG). The new GDDR5, the first graphics DRAM designed by Elpida, was developed at the company's Munich Design Center in Germany.

Fitting 2GB worth of GDDR on a video card versus 1GB usually means that the pcb size/length will probably be the same as current 2GB cards....maybe a tad bit smaller, who knows. I'm not sure what nm process current cards use for their GDDR5, so its just a guess.

Uhm dude that one chip is 2gig in size.

No, that chip is 256MB. 2Gb = 256MB. So that means to get 1GB of GDDR5 on a card, they would only need to use 4 chips instead of 8.

First thing I think of when I see Gb whether it be like GB, gb, or Gb, I think Gigabyte. My mistake.

so the title of this thread is a little mis-leading ?

Not if you bother to understand PC hardware. Much like a 1TB HDD isn't 1TB when formatted, but then again that never stopped idiots from suing and winning.

2Gb= 2048 million bits = 256 million bytes

8 bits to the byte and all that.

Gb is Gigabit
GB is Gigabyte
8 bit = 1 byte
So, 2Gigabits GDDR5 Memory Chips = 2,048 Megabits = 256 Megabyte per chip.

Todays HD5870 1GB version is 128MB x 8 chips total = 1024MB/1GB.
HD5870 Eyefinity version has 2GB memory from 128MB x 16 chips total = 2048MB/2GB.
So Eyefinity 2GB version consume power more than 1GB version because of more chips.

If you use 2Gb chip(256MB) you can use 256MB x 8 chips to do 2 Gigabyte memory on a card.
Less power consumption.

Note : if GPU memory width is 256-bit like 5870, it could not make 256MB x 4 for 1 Gigabyte card.
They need 8 chip for 1 card such as 256MB x 8 or 128 MB x 8 instead.
Because of each memory chip contain 32-bit width.

Elpida needs to get back to work on a regular DDR3 IC with copper interconnects to fill the void left when they stopped making J1108BASE Hypers.
