The 1024-bit RVV cores in the K3 are mostly that size to feed a matmul engine. While the vector registers are 1024-bit, the two exexution units are only 256-bit wide.
The main cores in the K3 have 256-bit vectors with two 128-bit wide exexution units, and two seperate 128-bit wide vector load/store units.

But yes, RVV already has more diverse vector width hardware than SVE.
