Since its much belated release, Nvidia's DGX Spark mini AI box has enjoyed a mixed reception. It's technically interesting, but super expensive and arguably not that powerful, for the money at least. Now no lesser an authority than John Carmack, he of OG Doom fame, reckons the little gold box of AI power has thermal issues limiting its performance. And that has us doubting whether the chip inside the DGX Spark would make for a good laptop APU, more on which in a moment.
In a post on X, Carmack says his DGX is topping out at just 100 watts of power draw, far below what he says is the DGX's 240 watts rating. The result is roughly half the performance quoted by Nvidia.
