Samsung to Demo 37 Gbps GDDR7 Memory Next Month

Samsung Electronics will demonstrate its next generation GDDR7 memory chips at the IEEE Solid State Circuit Conference (SSCC), to be held in San Francisco in February. The company had teased GDDR7 way back at its Tech Day in 2022. The GDDR7 memory standard is targeted squarely at graphics cards and game consoles, it offers a 2x bandwidth gain over the current GDDR6. Samsung is expected to showcase a GDDR7 chip that's capable of 37 Gbps data-rate, with 16 Gbit (2 GB) density.

The GDDR7 memory standard leverages PAM3 signaling to achieve these high data-rates. The current GDDR6 standard uses NRZ signaling, while its off-shoot GDDR6X co-developed by NVIDIA and Micron Technology relies on PAM4 signaling. The standard also features four read clock modes, which should help with power management when the device is idling. Both NVIDIA and AMD are expected to implement GDDR7 with their next-generation GPUs. GDDR7 enters mass-production this year, and will feature in NVIDIA's GeForce RTX 50-series "Blackwell" graphics cards, as well as AMD Radeon RX 8000 series RDNA4.

If we forget about GDDR6X last gen memory module don’t really run hotter than the older GDDR5 ones. GDDR6 can reach double the speed of GDDR5 with the same power budget and hopefully the next gen will do the same.

Cooler then GDDR6 at the same speed.
But yeah. I have a 4090FE and if I OC the VRAM to 23,5Gbps then the VRAM is hotter then the GPU hotspot...

Will Micron be the only company making 3 GB modules? Samsung and Hynix seem to have only mentioned 2 GB.

I don't see NVIDIA increasing bus widths in the 50 series, so those 3 GB modules definitely look the most attractive (12 GB on 128-bit, 18 GB on 192-bit, 24 GB on 256-bit).
