Supercharging AI Inference with GDDR7
The output of the AI 2.0 training process is an inference model that can be employed to create new multimodal content from a user’s prompts. Since accuracy and fidelity increase with model size, there is an ongoing push for larger and larger inference models. As AI inference becomes increasingly pervasive and moves out from the data center to the edge and endpoints, it drives the need for more powerful processing engines with tailored high-performance memory solutions across the entire computing landscape.
GPUs have been the inference engines of choice, and in the case of edge and endpoint applications, such as servers and desktops, these have been GPUs using GDDR6 memory. GDDR6, however, has reached the practical limit of standard NRZ signaling at 24 Gigabits per second (Gbps) data rates. To meet the bandwidth needs of future GPUs, a new generation of GDDR using a new signaling scheme is required. Enter GDDR7 memory which using PAM3 signaling can boost data rates to 40 Gbps and higher.
