Which is basically memory bandwidth problem, which a large L3 cache helps a lot with. I've seen the same things with ClickHouse, having a larger L3 cache and fewer cpu cores can increase performance significantly.

Doesn't a lot of optimization target making your code and data more cache friendly because memory latency (not bandwidth?) kills performance absolutely (between other things like port usage I guess)?
If something is in L3 it is better for CPU "utilization" than stalling and reaching out to RAM. I guess there are eventually diminishing returns with too much cache, but...
