General Electric CF700
The General Electric CF700 (military designation TF37) is an aft-fan turbofan development of the CJ610 turbojet. The fan blades are an extension of the low-pressure turbine blades.

gollark: Doesn't `rand()` return values up to some smallish constant?
gollark: Only Turing and later have good enough on-chip processors to use it, apparently.
gollark: nvidia-open is quite funny, since they just moved all of the proprietary stuff to a giant tens-of-megabytes firmware blob.
gollark: I think we still just run on L1/2/3 caches, occasionally L4 things, then RAM, and possibly persistent-memory DIMMs or really fast NVMe disks.
gollark: I don't know all the magic semiconductory details, but higher voltage generally means more power, but is needed to maintain stability if you're switching things fast.
