So, Nvidia's little gold box of pure AI power, the DGX Spark is finally out. But is it any good? The answer depends who's doing the asking and what they're asking of the Spark. By some common measures, it's no faster than another small box based on AMD's Strix Halo chip that's available for about half the price. Ouch.
Much of this comes down to the minor matter of floating point math precision. I can feel your eyes glazing over, but bear with me. The finer details aren't that important. All you really need to know is that lowering the floating point precision being used can speed up performance at the cost of eventual AI model accuracy.
