Advanced Micro Devices (AMD) has launched a suite of new data center and PC processors at CES 2026, intensifying its competition with Nvidia in the booming AI chip market. CEO Lisa Su unveiled the MI440X accelerator for enterprise data centers and the high-performance MI455X, while previewing a future MI500 series claimed to deliver a 1,000-fold performance leap.
The MI440X is designed for smaller, on-premise corporate data centers, allowing companies to run AI models locally and retain sensitive data. This move targets enterprises taking incremental steps into AI adoption without relying entirely on large cloud providers. Alongside it, AMD highlighted the MI455X accelerator, described as offering a 10x performance improvement over the previous MI355X generation, forming the backbone for demanding AI workloads like training and inference at scale.
A key highlight was the appearance of OpenAI President Greg Brockman on stage with Su, confirming the critical role of AMD's chip advancements for OpenAI's vast computing needs. This public collaboration underscores a multi-billion dollar annual revenue deal signed between AMD and OpenAI in October 2025. The first deployments of chips from AMD's MI400 series are expected to roll out this year.
AMD also announced the Helios AI rack system, which combines the MI455X with the upcoming Venice CPU, scheduled for sale later in 2026. For the consumer and PC market, AMD launched the Ryzen AI 400 Series processors and Ryzen AI Max+ chips, designed to run AI locally on devices without relying on cloud systems.
Looking further ahead, AMD previewed its MI500 series of processors, slated for 2027. The company claims this new range will deliver performance gains of up to 1,000 times compared to the MI300 series introduced in 2023, representing a potential major step change in its AI hardware capabilities.
The announcements come as AMD faces intense pressure to gain market share in an AI chip sector dominated by Nvidia, which also unveiled its next-generation Vera Rubin platform at CES. AMD stock edged higher following the announcements, with Wall Street analysts maintaining a Strong Buy rating.
