世界上最大的GPU！16个Tesla核心和512GB显存
英伟达首席执行官Jensen huang在2018年的GTC上发布了世界上最大的GPU DGX-2在近日进行了迭代，该图形计算机器拥有16个Tesla V100 GPU和512GB HBM2内存，是一个具有统一内存空间的主机计算系统。这种大功率计算单位常用于数据中心和模拟机器学习，目前英伟达取消了该GPU的功耗限制，使其可以满功耗运行。
DGX前代是使用48V配给型电子系统供能来减少驱动系统所需要的电流量，后来由于运算量的增加配备了12KW的电源，但英伟达没有说明这样增加的功耗是否会带来热量的增加以及冷却系统的详细改进。
该图形计算单位更新了供能系统后默认功耗可达到10KW，最高功耗高达12KW，浮点运算能力从默认的2 petaflops提高到2.1 petaflops。功耗增加下的运算能力提升并不强，但运算频率的增加可以让CPU可以更好的发挥，主板总线的其他IO设备可以满速运行。
该GPU前代发布时零售价为40万美元(约280万人民币)，但功能系统更新后英伟达尚未更新价格。
