Samsung releases fastest GDDR-4 SGRAM

SAMSUNG IS WELL ready for the upcoming war between Nvidia's G80 refresh and ATI's R600.

The semiconductor division of this manufacturing giant announced that it has started mass production of 512Mbit (64MB) GDDR-4 SGRAM chips boasting a massive 1.4GHz working clock in DDR mode.

The K4U52324QE-BC07 chips work at a 2.8GHz clock speed, which is astonishing and the amount of bandwidth both Nvidia and ATI can count on is mind-boggling.

If you pair a 384-bit wide G80 GPU with these chips, you will end up with around 134.4 GB/s, a third faster than the in the currently-available GeForce 8800GTX. However, even these chips won't be enough for the 8850/8900 to beat the R600 in terms of sheer memory bandwidth.

If DAAMIT plugs these into its its upcoming water-cooled R600 Uber Edition, with a 512-bit memory controller you get 179.2 GB/s of bandwidth, or more than double the bandwidth than GeForce 8800GTX can currently boast (86.4 GB/s).

Just some food for thought.

In Nvidia's shoes, you'd be bonkers to think about doing an "8850" or "8900" if this memory wasn't on the PCB. µ
