In HFT single-threaded performance is king so that's why we're all still on Intel. AMD is making progress but not just quite there yet.

Huh. My experience has been that AMD wins that unless your application is so small that it can fit into Intel's smaller cache. And the new 3D architecture from AMD I thought would make your developers drool, allowing them to actually inline everything instead of being scared of building apps that are too big to fit into cache

[bitcharmer]

Not my experience at all and I work across different teams who own different latency sensitive apps. Most of them have unhygienically huge working sets.

To be clear: bitcharmer says "we" to mean "fellow HFTs" not "Jane Street".

[bitcharmer]

Yes. Thanks, should have made that more explicit.
