It sounds exciting until you do the maths.

NVIDIA Grace is based on Neoverse V2, also used by Graviton 4, it is derived from the ARM Cortex-X3, used in Snapdragon 8 Gen 2 and Mediatek Dimensity 9200.

With the context above, 50% IPC improvement in 2028 doesn't sounds that impressive. We since have Cortex-X4, Cortex-X925 and currently C1-Ultra used in Dimensity 9500. And we are expecting C2 this year. Considering every generation has had higher than 10% IPC improvement. That Rosa would be about the same as C2, or roughly M5.

Neither ARM or Apple is sitting still.
