I think the word that was being grasped for is 'faster'.

It suffers in that doesn't sound very technical.



GPU can perform more operations than CPU, but GPU is slower than CPU, not faster.


Yes, throughput vs latency is a very important distinction. An airplane is always faster then a train, but if what you are measuring is throughput, a train can be more performant. It depends on the context, but that's fine. There is no such thing as a made-up word if the word has a meaning, and is regularly used by a group of people.


So is the GPU more or less 'performant?'

That's right - the CPU is faster at completing the job, though the GPU executes instructions more quickly.
