GDDR7 Memory Supercharges AI Inference

GDDR7 memory has emerged as a cutting-edge solution for enhancing AI inference capabilities, boasting a performance roadmap of up to 48 Gigatransfers per second (GT/s) and a memory throughput of 192 GB/s per device. This new generation of graphics memory is essential for the increasing demands of AI workloads, particularly in inference applications where low latency and high bandwidth are critical. GDDR7 memory significantly outperforms its predecessor, GDDR6, by utilizing three-bit pulse amplitude modulation (PAM3) encoding, which allows for a 50% increase in data transmission rates. The memory can deliver 128 GB/s of bandwidth, more than double that of LPDDR5T. Additionally, GDDR7 incorporates advanced reliability features, including on-die error correction and data integrity enhancements. The transition to four 10-bit channels from two 16-bit channels in GDDR6 further optimizes performance. The Rambus GDDR7 Controller IP is designed to support high-memory throughput and programmability, facilitating the integration of GDDR7 in various applications. As AI inference models grow in size and complexity, the need for high-performance memory solutions like GDDR7 becomes increasingly vital for AI accelerators and GPUs deployed in edge computing environments.
