AMD has announced its new CPU, NPU, and GPU architectures, which are specifically designed to support AI infrastructure across a range of devices from data centers to PCs. Alongside these architectures, AMD has also revealed an expanded AMD Instinct accelerator roadmap and a new Instinct MI325X accelerator, set to be available in Q4 2024. This new accelerator offers impressive specifications, including 288GB of HBM3E memory and 6TB/s of memory bandwidth. AMD boasts that this will provide twice the memory capacity and 1.3 times the bandwidth compared to Nvidia’s H200, while also delivering 1.3 times better compute performance.

One key aspect of the Instinct MI325X upgrade is the memory capacity, as it utilizes the original CDNA 3 architecture, similar to the MI300X. Additionally, the clockspeeds remain unchanged at 2.1GHz. However, AMD has exciting plans for the future of their Instinct accelerator series. The next release after the MI325X will be the Instinct MI350 series, expected to launch in 2025. This series will be powered by AMD’s new CDNA 4 architecture, promising a substantial 35 times increase in AI inference performance compared to the previous Instinct MI300 Series. Looking even further ahead, AMD has announced the Instinct MI400 series, slated for release in 2026, which will be based on their CDNA Next-Gen architecture. Unfortunately, AMD did not provide detailed information about this series.

AMD’s Instinct MI300X accelerators have already gained significant adoption from notable partners and customers, including Microsoft Azure, Meta, Dell Technologies, HPE, Lenovo, and others. This adoption can be attributed to the exceptional performance and value proposition offered by the AMD Instinct MI300X accelerators. Brad McCredie, Corporate Vice President of Data Center Accelerated Compute at AMD, emphasized the company’s commitment to innovation and its aim to meet the expectations of the AI industry and customers with their leadership capabilities and performance.

AMD’s latest announcements highlight the continued progress and dedication of the company in advancing AI infrastructure. The focus on end-to-end AI solutions, spanning from data centers to consumer devices, demonstrates AMD’s understanding of the evolving needs of the AI industry. By providing powerful and efficient architectures, AMD aims to enable the next evolution of data center AI training and inference.

It is evident that AMD is positioning itself as a key player in the AI market. The company’s relentless pace of innovation and commitment to delivering cutting-edge technology is gaining recognition and attracting partnerships with industry leaders. The expanded AMD Instinct accelerator roadmap indicates a long-term vision for AI acceleration, spanning multiple series and architectures.

AMD’s approach to AI infrastructure is not limited to the capabilities of their accelerators alone. They have also been actively collaborating with partners to optimize software solutions for AI workloads. This holistic approach ensures that customers can benefit from both hardware and software advancements, resulting in improved performance, efficiency, and overall AI capabilities.

Additionally, AMD’s dedication to annual product releases signifies a commitment to keeping up with the rapidly evolving AI landscape. With each new release, AMD aims to push the boundaries of AI performance and deliver the latest advancements in AI training and inference. This regular cadence of product updates allows customers to stay at the forefront of AI technology, ensuring they have access to the latest innovations and capabilities to meet their specific AI requirements.

In conclusion, AMD’s recent unveiling of new CPU, NPU, and GPU architectures, along with their expanded Instinct accelerator roadmap, showcases the company’s determination to power end-to-end AI infrastructure. By providing high-performance and efficient accelerators, AMD aims to meet the demands of the AI industry and empower customers with the necessary tools to succeed in their AI endeavors. With their annual cadence of product releases and continuous collaboration with partners, AMD is positioned to play a significant role in driving the next evolution of data center AI training and inference.
