Journal TehDuffman's Journal: Samsung Mass Produces GDDR4 Memory

"The new GDDR4 chips operate at 2400MHz, an unprecedented speed-bin for graphics memory, and also features lower power consumption when compared to the GDDR3. The devices are produced using 80nm process technology, which increases clock-speed potential and lowers overall power consumption. When measured against GDDR3 at the highest comparable speed (2.00GHz), GDDR4 showed a 45% power savings. Samsung said that the first GDDR4 chips have 512Mb capacity."

"The product may be approximately 15% faster compared to the current flagship offering from the company. It is highly likely that Samsung will begin shipments of GDDR4 to ATI."
