Samsung confirms model names 28 Gbps and 32 Gbps is sampling

Designed for the next-gen GPU series.

Samsung has officially listed two memory modules based on GDDR7 technology on their website. Just as teased last week at GTC 2024, the first phase of GDDR7 deployment will focus on 28 Gbps and 32 Gbps speeds, already much higher than commercially available GDDR6 and GDDR6X series.

Currently, Samsung is planning to launch 16 Gb (2 GB) density, with no mention of 24 Gb (3 GB) series. While it is unclear who will be Samsung’s first customer for GDDR7 memory, the company is already sampling the chips and them being displayed at GTC 2024 is a clear sign that NVIDIA is one of them. The lack of 3 GB memory may suggest that the company will rather stick to regular capacities.

Previously, it was revealed that NVIDIA is exploring 28 Gbps modules for its next-gen RTX 50 series, codenamed “Blackwell”. Such a goal could be achieved with either of the modules, but 32 Gbps chips give NVIDIA more flexibility in adjusting those clocks. Samsung has already developed 24 Gbps chips based on GDDR6 technology, but neither AMD nor NVIDIA were using chips at this speed for their products.

Other companies, including Micron and SK Hynix, have yet to list the GDDR7 technology and confirm the exact speeds both companies are targeting.
