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.
