Like past GDDR revisions, GDDR 5 ups the maximum available data transfer rate between video memory and GPU – to 20GB/s, in this case. Error compensation, adaptive interface timing and the ability to adapt the signalling characteristics to match patterns in the data being sent over the bus all contribute to the higher transfer rate. Currently, the fastest GDDR 4 modules out there offer a throughput of up to 16GB/s. Qimonda preferred to compare its new GDDR 5 chip to GDDR 3, but that’s because it’s skipping GDDR 4 and going straight to 5.
