NVIDIA publishes this chip's headline as up to 1 petaFLOP of FP4, and footnotes that figure on its own DGX Spark page as a theoretical rate using the sparsity feature. Both numbers are shown here: 1,000 TFLOPS with sparsity, and 500 without, which is the figure comparable with every other accelerator on this site. The same NVIDIA page is the source for the 128 GB of coherent unified memory and the 273 GB/s of bandwidth. It does not publish an FP32 figure for this chip, so the FP32 shown here comes from elsewhere and has not been confirmed against an NVIDIA document.
