Samsung has officially started listing the first GDDR7 memory modules that will be powering the next-gen GPUs coming later this year.
Samsung Officially Lists GDDR7 Memory: 28 Gbps & 32 Gbps DRAM Now Sampling For Next-Gen GPUs
Samsung is one of the trio of memory manufacturers who will be offering their next-gen GDDR7 memory solutions to graphics vendors such as NVIDIA, AMD, and more. The other two include SK hynix and Micron who have also announced their current-gen products and teased what the new standard is capable of, offering up to 40 Gbps pin speeds and up to 64 Gb densities.
When it comes to Samsung, the company will be sticking to a more reasonable 16 Gb density which allows for 2 GB VRAM per module. So the capacities will be pretty much the same as we have on the current generation of graphics cards. Each module will feature a 32-bit wide bus interface and a refresh rate of 16K/32ms. The GDDR7 memory modules will come in the 266 FBGA package & there are two speeds currently listed.
We have the standard 32 Gbps die and the low-voltage optimized 28 Gbps dies. It is very likely that the first iteration of GDDR7 GPUs would utilize the 28 Gbps dies with only a few high-end variants or their refreshes getting 32 Gbps pin speeds. Both will be a major improvement over GDDR6 which peaks out at 24 Gbps and we have only seen up to 22.5 Gbps speeds on certain GPUs such as the NVIDIA GeForce RTX 4080 SUPER. That's a 24.5% improvement for the 28 Gbps and a 42% improvement for the 32 Gbps in speed alone.
Samsung also recently displayed its GDDR7 memory modules at GTC and their status has now been moved to sampling. Following are some of the configurations you can expect with 28 Gbps and 32 Gbps modules:
- 512-bit / 28 Gbps / 32 GB (Max Memory) / 1792 GB/s (Max Bandwidth)
- 384-bit / 28 Gbps / 24 GB (Max Memory) / 1344 GB/s (Max Bandwidth)
- 256-bit / 28 Gbps / 16 GB (Max Memory) / 896.0 GB/s (Max Bandwidth)
- 192-bit / 28 Gbps / 12 GB (Max Memory) / 672.0 GB/s (Max Bandwidth)
- 128-bit / 28 Gbps / 8 GB (Max Memory) / 448.0 GB/s (Max Bandwidth)
- 128-bit @ 32 Gbps: 512 GB/s (8 GB)
- 192-bit @ 32 Gbps: 768 GB/s (12 GB)
- 256-bit @ 32 Gbps: 1024 GB/s (16 GB)
- 320-bit @ 32 Gbps: 1280 GB/s (20 GB)
- 384-bit @ 32 Gbps: 1536 GB/s (24 GB)
- 512-bit @ 32 Gbps: 2048 GB/s (32 GB)
The first GDDR7 graphics cards are probably going to arrive later this year as production on the new memory ramps up. It will be a new beginning for the whole client graphics memory market and we look forward to how it progresses.
