After some time since manufacturers such as Samsung and Micron announced that they would develop GDDR7 memory, JEDEC (Joint Electronic Device Engineering Committee) finally released a series of standards for GDDR7 memory in March, which seems to be a sign that new memory will be coming soon.
According to information released by JEDEC, GDDR7 memory will be the first dynamic random access memory to operate at high frequencies using a "pulse amplitude modulation (PAM)" interface that improves signal-to-noise ratio, performance, and energy efficiency. It will also double the number of independent channels, from 2 to 4 channels in GDDR6, and support densities from 16Gbit to 32Gbit, as well as dual-channel mode, doubling the system's capacity.
In addition, GDDR7 memory incorporates the latest data integrity features, as well as improved training accuracy and speed.
We've previously reported on Samsung's GDDR7 memory, which can achieve 1 per secondWith a bandwidth of 5 Tbps, you can reach GDDR6 11 of 1Tbps bandwidth4 times, the performance improvement is still considerable.
Combined with the previous news, GDDR7 video memory may be about to meet us in the near future, and perhaps this will also be related to the NVIDIA RTX 50 series graphics cards that will be released in the fourth quarter of 2024.
