Samsung Unveils Cutting-Edge GDDR7 Graphics Chips at Nvidia's GTC 2024 Event, Boasting Impressive Features and Potential Integration in Future GPUs

Samsung recently showcased GDDR7 graphics chips at Nvidia's GTC 2024 event. These modules have a capacity of 16Gbit or 2GB and offer an impressive bandwidth of up to 32Gbit/s per pin.

Based on images of Samsung's promotional material on HardwareLuxx's website, it seems that GDDR7 modules are 20% more efficient than GDDR6, operating at a voltage of 1.1V compared to the industry standard of 1.2V. These chips also demonstrate a 70% reduction in thermal resistance, attributed to an optimized circuit design. Additionally, they produce less heat during high-speed operations.

According to Tech website VideoCardz, Samsung's GDDR7 chips may be utilized in upcoming RTX50 GPUs from Nvidia. Rumors suggest these GPUs will feature GDDR7 modules with speeds of 28Gbit/s rather than 32Gbit/s. However, these claims have not been confirmed by Samsung or Nvidia.

In 2023, Samsung introduced its first generation of GDDR7 memory chips boasting a bandwidth of 32Gbit/s per pin. This year, the company hinted at even faster GDDR7 memory chips with bandwidths reaching 37Gbit/s per pin. Additionally, SK hynix unveiled GDDR7 vram earlier this year, offering a more energy-efficient variant with speeds of up to 35.4 Gbit/s.

The transition to GDDR7 signifies a significant advancement in memory technology, doubling the bandwidth of GDDR6 and implementing PAM3 encryption for data transfer. This encryption method utilizes three voltage levels for signal transmission, allowing for more bits per clock cycle without increasing the clock speed.

Rumors suggest that AMD and Nvidia will incorporate GDDR7 in their next generation of video cards. The Nvidia GPU Technology Conference is scheduled for March 18 to 21, 2024.
