Samsung Unveils Revolutionary GDDR7 Memory Module
Samsung is set to showcase its groundbreaking GDDR7 memory module at the upcoming ISSCC event, marking a pivotal moment in the evolution of graphics memory technology. While it remains uncertain whether the cutting-edge 42.5 Gbps GDDR7 will make its way to consumer graphics cards, its potential capabilities underscore a significant advancement in memory speed.
Event Details
The International Solid-State Circuits Conference (ISSCC) will be held in San Francisco, California, from February 16 to February 20. Among various presentations, a special segment on “Nonvolatile Memory and DRAM”will take place on February 19. Although this part of the event is not open to the public, the agenda can be accessed through the ISSCC website.
Performance Highlights of GDDR7
At ISSCC, Samsung will present its GDDR7 DRAM, featuring an impressive speed of 42.5 Gbps. This module, expected to be 24 Gb (or 3 GB), not only prioritizes high-speed operations but also enhances power efficiency relative to earlier GDDR6 versions. Although GDDR7 memory is significantly faster than GDDR6, the 42.5 Gbps module may currently exceed the requirements for GPU integration.
Future Applications in Gaming Graphics
Despite the high specifications, it is anticipated that GDDR7 memory may find its way into future graphics offerings, potentially including NVIDIA’s upcoming RTX 60 series cards. Currently, the NVIDIA Blackwell RTX 50 series GPUs are set to feature GDDR7 memory operating at 28 Gbps, which outpaces the GDDR6 memory speeds of the existing RTX 4090 by 4 Gbps.
The 42.5 Gbps speed represents a substantial increase over the existing 24 Gbps GDDR6, boasting a remarkable 77% performance enhancement. However, it is worth noting that many current GPUs, including AMD’s flagship RX 7900 XTX and NVIDIA’s RTX 4090, are constrained to memory speeds of approximately 20-21 Gbps.
Projection of Memory Bandwidth for the RTX 5090
Additionally, NVIDIA’s flagship Blackwell GeForce RTX 5090 is projected to utilize 28 Gbps memory, with possibilities for improvement beyond 30 Gbps in future iterations—mirroring the progression seen with GDDR6 technology. Expected to feature 32 GB of GDDR7 memory operating on a 512-bit bus, the bandwidth may reach between 1.7 to 2.0 TB/s, representing an increase of 1.7x to 2.0x over the RTX 4090. Hypothetically, if the RTX 5090 were to integrate GDDR7 operating at 42.5 Gbps, it could approach a memory bandwidth limit of nearly 2.5 TB/s.
