Samsung begins production of 50nm GDDR5 memory

It's still a little ways away from actually landing in some graphics cards, but Samsung has announced that it has begun mass production of its new 50nm GDDR5 memory, which promises to support a maximum data transfer speed of 7.0 gigabits per second and boast a maximum bandwidth of 28 gigabytes per second. What's more, according to Samsung, the shift to a 50nm manufacturing process also increases production efficiency by a full 100 percent, and allows the memory to operate at 1.35 volts, which is a 20 percent reduction compared to current GDDR4 memory. From the looks of it, however, manufacturers will have to make do with a 32Megabit x 32 configuration (also configurable as a 64Mb x 16 device) initially, although Samsung says it plans to expand the 50nm process throughout its graphics memory line-up by the end of the year.

Next-generation ATI Radeon cards to pack GDDR5 memory

by Darren Murph, posted May 21st 2008 at 2:04PM

A full six months after Samsung took the wraps off of GDDR5 memory, along comes word from AMD that the next-generation ATI Radeon graphics cards will boast said technology. Apparently AMD will be tapping Qimonda for its supply of GDDR5 modules, which should boost gaming performance as well as benefit stream processing, "where GPUs are applied to address complex, massively parallel calculations." As Hot Hardware points out, the release comes just weeks away from the rumored debut of the Radeon 4000 series, so if our deductive reasoning is sound, we'd surmise that the looming Radeon 4800 will indeed feature GDDR5.

Samsung announces world's fastest memory: GDDR5

Gadzooks gamers, Samsung just announced what they are calling the world's fastest memory: GDDR5. The new series five, double-data rate memory chip transfers data at a lickity quick 6Gbps -- about 4x faster while using 20% less power than the GDDR3 memory found in modern GPUs and the PS3. Compare that to their 4Gbps GDDR4 chips and you'll understand the fuss. The chips have already been delivered in samples to the likes of NVIDIA and ATI. Samsung expects the series five chips to capture more than 50 percent of the high-end PC graphics market by 2010.
