Graphics chip makers are on a never-ending quest for improved performance, with increasingly intricate graphics processing unit chip designs that already transcend the complexity of the CPUs used in Macs and PCs, and ever-faster board architectures. ATI Technologies Inc. has taken the next step in that endeavor with the implementation of DDR-2 -- newer, faster memory -- on some new graphics card test designs.
DDR-2 is second-generation double data rate (DDR) dynamic RAM -- memory chips that work even faster than the DDR RAM used in today's graphics cards (and, increasingly, computers too). ATI said it's the first to demonstrate a "visual processing unit" (or VPU) using DDR-2.
