How the 32 TOPs of Jetson AGX Xavier is calculated?

This site ( shows that AGX Xavier supports 32 TOPs. I think it’s huge. I wonder how this speed was calculated.
In my calculations, this device has 512 1.3GHz GPU cores, which is equivalent to 666 GOPs. In addition it has 64 1.3GHz Tensor cores, each of which can perform 64 operations simultaneously, resulting in 4.92TOPs. The sum of the two yields 5.58 TOPs. I think I’m missing something. What’s the right calculation?

Hi jerryahn, please refer to this FAQ for Jetson AGX Xavier performance:

I think I overlooked precision. I calculated based on single-precision only.
Amazing resource it supports!
Thanks you.
