5880，价格上会有什么变动呢？目前英伟达还没有公布价格。不过，根据两款标准版产品的定价——RTX 6000为6800美元，RTX 5000为4000美元，可以猜测RTX 5880应该会介于这两者之间。但考虑到RTX 4090 D的价格一分没降——依然是1599美元，因此，就算RTX 5880给到了6800美元的售价，也并不会让人感到太过意外。芯片方面，标准版RTX 6000 Ada和RTX 5000 Ada，搭载的都是AD102——面积为609平方毫米，拥有18,432个CUDA核心。基于此，英伟达有着充分的灵活性，来定制RTX 5880 Ada的芯片。而考虑到CUDA核心的数量，RTX 5880 Ada采用的应该就是AD102的某个变体。根据美国的“芯片禁令”，向中国出口的显卡总处理能力不得超过4,800 TPP。但RTX 6000 Ada的TPP达到了5,828，超出了这个限制。显然，RTX 5880 Ada的推出，将会填补这一市场空缺。具体来说，RTX 5880 Ada配备了14,080个CUDA核心，相当于110个流式多处理器（SMs）。而完整的AD102核心则拥有18,432个CUDA核心，也就是144个SMs。这意味着，RTX 5880比RTX 6000的CUDA核心少了23%，只比RTX 5000多了10%。尽管英伟达在RTX 5880上减少了一部分CUDA核心，但这款显卡依旧维持了与RTX 6000相同的显存架构——48GB显存和384位接口。因此，RTX 5880仍能提供与RTX 6000相同的960 GB/s的内存带宽。性能方面，RTX 5880在单精度浮点处理能力上达到了69.3TFLOPS，比RTX 5000高6%，但比RTX
