> Graviton4 processors deliver up to 30% better compute performance, 50% more cores, and 75% more memory bandwidth than Graviton3.

This seems ambiguous. Presumably this is 50% more cores per chip. What about "30% better compute performance" and "75% more memory bandwidth": is that per core, or per chip? If the latter, then per-core compute performance would actually be lower.

Also, "up to" could be hiding almost anything. Has anyone seen a source with clearer information as to how per-core application performance compares to earlier Graviton generations?
