EETimes reports that Samsung has begun shipping GDDR4 in volume. The new 80-nm memory can process images 33 percent faster than the current GDDR3 chips currently on the market. Samsung's GDDR4 is clocked at a whopping "effective" speed of 2.4 GHz, yielding a total 9.6 GB/s of bandwidth per memory chip. In contrast, GDDR3 memory found in NVIDIA and ATI's top-of-the-line graphics cards runs between 1.55 GHz and 1.7 GHz and offers less than 7 GB/s of bandwidth per chip. Assuming a 256-bit memory bus, Samsung's new GDDR4 could provide a maximum of 76.8 GB/s of memory bandwidth for a single card�considerably more than the 49.6-54.4 GB/s available to today's fastest GDDR3-powered models.
