GDDR2014 may debut in 6

Technical details are now being worked out by AMD and JEDEC technicians.

GDDR3 memory debuted in 2004. Since then, a lot of water has flowed down the Danube, but in the case of low-end video cards we can still meet it. GDDR4 has never been so successful. Although AMD has applied it to the Radeon X1950 XTX, HD 2900 XT, and HD 3870, since memory has not been able to significantly outperform its predecessor in practice, it is essentially only a curiosity left. The current GDDR5 standard has definitely exceeded expectations. AMD and NVIDIA have already commercialized products where the memories run at 6,0 GHz effective clock - overclocking this can even exceed the 7,0 GHz limit. This, combined with a 384-bit memory bus, results in quite brutal bandwidth. Engineers aren’t really rushed by time, yet they’re already working on the GDDR6 standard, as the list of companies interested in development (NVIDIA, Intel, Qualcomm, Texas Instruments, Cisco, and others) is quite long.

GDDR6 may first appear in 2014 and remain on the market until 2020.
