## AI 摘要

NVIDIA下一代AI芯片Rubin TDP高达2,300W，较Blackwell的1,000-1,400W显著提升。该芯片通过软件提供Max-P（2,300W）与Max-Q（1,800W）两种功耗配置：Max-P追求极致性能，但机架功耗增加20%而性能增益不足此比例，能效比降低；Max-Q则优化每瓦性能。用户可在2,300W上限内自定义功耗，部分超大规模数据中心已选择降功耗运行以优化能效比并应对电力限制。

PROFESSIONAL POWER EFFICIENCY ALERT： Rubin's chip level TDP increases up to 2，300W vs 1000-1400W for Blackwell. Supply chain rumors have indicated that there are 2 different "SKUs" with different power and performance profiles： a Max-P variant at 2，300W and a Max-Q variant at 1，800W. However， these are not distinct hardware SKUs but the 2 default power profiles that Nvidia is offering users based on their workload needs. Max-Q is what Nvidia believes offers the best performance per Watt. Max-P offers the greatest absolute performance though this would come with an efficiency penalty. Running the Max-P setting results in a 20% increase in rack power draw but the performance gain fall well short of this 20% power consumption increase. These power profiles are software managed. Users can also choose whatever max power draw they prefer （as long as it is no more than 2，300W per GPU） and this has been the case for previous GPU generations as well. Several hyperscalers and labs have chosen to run their GPUs at lower power to optimize for performance per Watt as well as taking into account power availability constraints.
