HFT
- earenndil 8y agoIsn't their primary concern latency? I doubt a few GHz boost would do anything for them.
- ShinTakuya 8y agoDepends on how low the latency already is. If you're already <0.5ms away network wise then perhaps shearing off 0.1ms from a 1ms operation could make a significant difference.
- ShinTakuya 8y agoAlso some types of HFT don't rely on network latency at all, it can be based on other factors.
- xxs 8y ago>Isn't their primary concern latency? It is, but at some point you can't do much more about the network latency; shaving off a couple dozen us, might the difference of getting the price/quote or missing it out. Especially, when you play versus similarly equipped firms.
- allenrb 8y agoBinned & overclocked i9-9980XE’s are already available though. I’m honestly at a bit of a loss to understand Intel’s latest offering. But hey, it made us stop laughing about 10nm for a few minutes.
- a_imho 8y agoAre there dedicated HFT ICs?
- philjohn 8y agoAccording to a HFT programming talk posted recently there are some trading houses using in-house designed ASICs.
- raverbashing 8y agoI'm guessing the chance of an eventual calculation error is not worth the potential speed gains (though you could run those Pi calculators to check for CPU stability) HFT is not so much about CPU speed but algorithmic optimization.
- xxs 8y agoBy nature HFT is not highly multithreaded and avoids handoff. So having more cores is not that different than having more discrete CPUs -- no benefits for cache locality/faster coherency. In that regard if latency is an issue overclocked 8700K (or 8086K) should be sufficient.
