On March 22, Nvidia only released renders of the 4nm GPU GH100 / H100 accelerator, so the NDA has only taken pictures of real hardware until now. The editors of ServeTheHome and CNet were given the opportunity to take a picture of a real accelerator:

Patrick J Kennedy from ServeTheHome (whose pictures you see above) had the opportunity to take a picture of the card (module) on April 7; however, Nvidia did not give permission for the publication until now in May.
There are no peculiarities of the SXM module, perhaps it is worth noting that compared to the Ampere, the GPU has been rotated by 90 °, so that the three HBM memories on each side of the core are oriented “longitudinally” to the longer side of the module.

According to information from the time of the March performance, the novelty should not be available in the first half of this year. In Japan, there was a possibility of pre-ordering the PCIe variant (20% lower number of function blocks, HBM2E instead of HBM3) for $ 33,000.
