With the WRF weather forecasting benchmark is significantly better performance with Sapphire Rapids over Ice Lake: the conus 2.5km model completed in 65% the time required for the top-end Ice Lake SP SKU. However, the 8490H 2P performance still came in short of the EPYC 9654/9554 processors and even the EPYC 9374F. WRF is one of the workloads that benefited a lot from 12 channel DDR5 memory with Genoa, just as WRF also very much enjoyed Milan-X. Though with that said it will also be interesting to see how WRF performance for the Intel Xeon CPU Max Series with its HBM2e memory.

During the WRF run the Xeon Platinum 8490H was averaging a 348 Watt power draw with a peak recording of 376 Watts.

Sapphire Rapids in many of these benchmarks not making use of accelerators was having troubles competing with Genoa, but at least generationally is showing a big uplift over 3rd Gen Xeon Scalable "Ice Lake" performance.

Often times a single Xeon Platinum 8490H was coming close to (or exceeding) the performance of two Xeon Platinum 8362 or 8380 processors.
