GRID卡的最大功耗怎么比较

大家好，
我注意到有关每个物理GPU的“nvidia-smi -q”命令输出的功率统计数据的一个有趣的事情。
如果您将最大功率限制加倍（因为每个板上有两个GPU），其等于超出板的公布最大值。
例如，K2为125W×2 = 250W，M60为162W×2 = 324W。
你可以看到它们高于K2和M60卡的公布最大值。
发布的最大值：
K2：225 W
M60：300 W
也许这种每GPU最大功率消耗允许单GPU暂时进入其“提升”模式。
而且，只有在电路板上的其他物理GPU远低于其最大功率消耗不超过整个电路板的公布限制的情况下才会发生这种情况。
是这样的吗？
谢谢！

Hi All,

I noticed an interesting thing about the power stats outputted from the "nvidia-smi -q" command for each physical GPU.  If you double the Max Power Limit (as there are two GPUs per board) that equals above the published maximums for the board.   For instance the K2 would be 125W x 2 = 250 W and the M60 would be 162W x 2 = 324W.  You can see those are above the published maximums below for the K2 and M60 cards.

Published Maximums:
K2: 225 W
M60: 300 W


Perhaps this per-GPU maximum power draw allows the single GPU to enter it’s “boost” mode temporarily.   And, that would only occur in the case that the other physical GPU on the board is far enough below its maximum power draw not to exceed the published limit for the entire board.  Is this the case?

Thanks!
