Micron has confirmed that it’s going to introduce its next-generation GDDR7 graphics reminiscence on its 1X nm node early subsequent 12 months. During Micron’s fiscal Q3 2023 earnings name, the corporate’s CEO talked about the upcoming GDDR7 reminiscence however didn’t present particular particulars relating to potential speeds.
Currently, GDDR6 reminiscence is transport with speeds as much as 20 Gbps, reminiscent of within the Radeon RX 7900 collection, whereas Micron’s GDDR6X know-how, present in NVIDIA’s RTX 40 collection, reaches speeds of as much as 22.4 Gbps on the RTX 4080. GDDR7 reminiscence will definitely be sooner than that. The query is how briskly?
As you would possibly count on, the primary iterations of the brand new GDDR reminiscence will not be as quick as those that come after. For instance, the primary GDDR6 reminiscence iterations used on GPUs had been clocked at 14 Gbps, however Samsung now has GDDR6 reminiscence that may go as much as 24 Gbps. With GDDR7, one thing comparable is prone to occur right here with GDDR7.
Due to the extremely excessive speeds, GPU producers may have the possibility to make use of narrower reminiscence buses whereas providing comparable reminiscence bandwidth. Moreover, the early 2024 timeframe for the discharge suggests we would see the primary GDDR7 merchandise come out later in that very same 12 months.
KitGuru says: Overall, the introduction of GDDR7 reminiscence brings the prospect of elevated efficiency and bandwidth to future graphics playing cards, however particular particulars and implementation will depend upon the person producers and their product releases.
