RTX Spark will have up to 600GB/s of memory bandwidth.

We just assumed that since it's a GB10 variant that it would have the same memory bandwidth as DGX Spark, 273GB/s. But it's reported that it will have double that, 600GB/s.

"The unified memory architecture brings up to 128GB of LPDDR5X RAM with a bandwidth of 600GB/s"
