How does the Nikon SB-910's overheating behavior compare with the SB-5000?

Nikon says the SB-5000 can fire 120 continuous flashes at 5-second intervals without overheating. Is there an equivalent published overheating or consecutive-firing specification for the SB-910, and how does its thermal protection behavior compare?

It's actually incredibly hard to tell you how that compares, since Nikon's never published that spec previously, and they don't tell you what power level the flash was on. Most speedlights, set to a lower power setting could achieve those numbers very easily.
If, however, we assume full power without any loss of output, though, then that's impressive and should be an improvement. The SB-910 could match the same firing pattern, but lowered the output of the flash when higher temperatures were reached vs. the SB-900 simply shutting down at around 50 full power pops.
See: The Jordon Collective's Youtube video on their SB-900 vs. SB-910 overheating test.

There does not appear to be a directly comparable published Nikon spec for the SB-910. That makes a one-to-one comparison difficult, especially since continuous-firing claims depend heavily on flash power level.
In practical terms, the SB-910 was designed to improve on the SB-900’s overheating behavior. Rather than abruptly shutting down as the SB-900 was known to do after heavy full-power use, the SB-910 reduces flash output when it gets too hot. Based on community testing, the SB-900 could shut down at roughly 50 full-power pops, while the SB-910 can continue firing by throttling output.
So: Nikon’s 120-shot SB-5000 figure is a useful published benchmark, but there is no clearly equivalent official SB-910 number in the provided information. The safest conclusion is that the SB-910’s thermal management is more graceful than the SB-900’s, but a direct numerical comparison to the SB-5000 isn’t available here.
