This organization has just announced the specifications of the GDDR7 standard, memory which will be implemented in the next generation of graphics cards from AMD and NVIDIA and which will replace GDDR6X. Samsung, Micron, SK Hynix, AMD and NVIDIA have already expressed their excitement after hearing the news, as it represents a significant change from the current generation GDDR6X.
GDDR7: twice as fast as GDDR6X
This new generation represents a significant change from GDDR6X, since it offers a throughput of 48 Gbps with a bandwidth of 192 GB/s. This data is double what GDDR6X offers us, whose speed reaches 24 Gbps with a bandwidth of 96 GB/s.
This new standard was designed with the increasingly growing use of Artificial intelligence and to satisfy the most demanding needs of users, both when playing games and when working with video editing, rendering and other applications.
GDDR7, unlike GDDR6X which uses 2 bits in 2 cycles, uses 3 bits in 2 cycles. This, added to the fact that it uses a PAM3 interface instead of SNR, and that the number of independent channels has been doubled (from 2 to 4), allows not only to increase the speed but also to reduce the energy consumption.
JEDEC’s announcement only confirms the information that Samsung had already published last July, but it allows us to know in more detail all the Features. However, this announcement represents the public launch of this new standard, although there are still a few months to see it implemented.
Market availability
The next generation of NVIDIA graphics, RTX50 with the Blackwell architecture, whose launch is scheduled for the end of this year, will (almost certainly) use HBM3E memory instead of GDDR7, so we will have to wait until at least 2025 to see the different variants that this manufacturer will launch on the market .
AMD is also working to implement GDDR7 in the next generation of its RDNA architecture graphics cards, but not in all models, as it is most likely that mid-range models will continue to use GDDR6X for the simple reason of reducing the costs and offer the most competitive products on the market.
Taking into account that AMD and NVIDIA release new graphics cards every two years, even though the GDDR7 launch took place in the middle of the development of these new generations of graphics cards, there is a minimal possibility that They include GDDR7 or delay their launch to be able to incorporate it, which is very unlikely, since it involves changing the design almost completely.
It is very likely that it will not be until mid-2025 that the first graphics with GDDR7 from AMD and NVIDIA. The only graphics manufacturer that has not spoken out so far is Intel, where it seems that it is not yet very clear on the roadmap it wants to follow in the graphics card sector.
