Not just Samsung and SK Hynix, the third major memory maker, Micron, has also joined the race in producing the high capacity GDDR7 memory.
Micron Starts Sampling 24 Gb (3 GB) GDDR7 Memory Modules Rated At 28 GT/s and 32 GT/s As Spotted on the Official Website
Finally, the third major memory maker has also started working on its own 24 GB or 3 GB GDDR7 (we will use 3 GB instead of 24 GB throughout the article for making it simple) memory modules. Micron, which recently exited the consumer market as it aimed to focus more on the data center, is now producing higher capacity GDDR7 memory modules. These memory modules are used on the latest GeForce RTX 50 series and other Workstation Blackwell cards.
As spotted on the official Micron website, the company has listed the latest 3 GB GDDR7 memory in its GDDR7 graphics memory part catalog. There are two variations: 3 GB @28 GTPS and 3 GB @32 GTPS. The former has already entered the Production phase, while the latter is in Sampling. With all three memory makers now producing 3 GB GDDR7 memory chips, it's expected that NVIDIA might soon deploy them in upcoming graphics cards, be it the delayed RTX 50 "Super" series or some refreshed RTX 50 series SKUs.
Until now, Samsung has remained the only manufacturer of 3 GB GDDR7 modules for NVIDIA cards, and even though only the RTX 5090 laptop GPU remains the only SKU in the series with 3 GB GDDR7, some upcoming SKUs are expected to adopt the newer module as well. We heard about NVIDIA working on the GeForce RTX 5050 with 9 GB GDDR7 memory, which will utilize three 3 GB GDDR7 memory chips, but as of now, it remains unclear whether NVIDIA will continue with its original plan. To combat the current situation, NVIDIA is reportedly re-introducing the GeForce RTX 3060.
Nonetheless, SK Hynix was the second memory maker to introduce its 3 GB GDDR7 memory modules, as we reported in February this year. Unlike Samsung's version, SK Hynix's 3 GB GDDR7 chips are rated at a much higher memory speed to deliver higher memory bandwidth for better performance. You will usually see Samsung's GDDR7 memory modules clocked at 28 Gbps, but SK Hynix's version will be rated at 36 Gbps. Micron's 32 Gbps GDDR7 modules are still quite fast, but we have yet to know when these chips will find their way onto newer GPUs.
