Hello @leoarthur
There should be no difference in performance, unless NPU is processing some heavy AI-related tasks. In such scenario, you’d experience performance spikes in general, depending on final NPU capabilities.
You have mentioned read-time editing, which raises a question – which product are you planning to use exactly? You see, Desktop Editors are directly designed to be used right on the device, i.e. for offline editing, but ONLYOFFICE Docs, which provides collaborative-editing, runs as a web-application.
Unfortunately, there is no official data sheet that’d demonstrate performance difference, however, comparing CPUs and NPUs directly, there is difference in computing power, so it must be taken is a scope of things too.
