OpenAI 暂停大规模使用谷歌 TPU 芯片，英伟达与 AMD 仍为核心供应商
OpenAI 最近宣布，尽管在初期阶段进行了测试，但不会大规模采用谷歌的 TPU 芯片。TPU（张量处理单元）是谷歌专为机器学习任务设计的定制化 ASIC 芯片，旨在加速神经网络的训练与推理。TPU 采用数据流驱动架构，能够实现高效的矩阵乘法流水线计算，从而减少内存访问延迟。图源备注：图片由AI生成，图片授权服务商MidjourneyOpenAI 表示将继续依赖英伟达的 GPU 和 AMD 的 AI 加速器来支持其模型的训练与推理。这是因为这两家公司的产品已经经过验证，并且 OpenAI 与它们之间已经建立了供应协议
