Do many people care about phone CPU performance? Sure, it needs to be good enough, but after that it's really far down on the list of things that matter.
What matters to everyone I know is screen size, camera quality and that a really small selection of apps (messaging, maps, email, browser, bank app) work well. Raw CPU performance is only a very abstract concept.
- nmfisher 6y agoRaw CPU performance, perhaps not. But people definitely do care about a specific set of user-facing, ML-driven functionality - think speech recognition, speech synthesis, realtime video filtering, and so on. Many of these are only barely possible on "pre-neural" mobile ARM CPUs, and at a significant cost to power consumption. Developing for newer devices is like night and day.
- martinald 6y agoNot sure that's true to be honest. Speech recognition on my old Pixel 2 is miles ahead of anything I've seen on any iPhone, which are 2-4x faster.

- nmfisher 6y agoGoogle's speech recognition is damn impressive, but I'm talking performance/power consumption, not "quality". Sticking a 2080 into an iPhone won't give you better speech recognition results, but it will give you bad results faster.
- RNCTX 6y agoBecause speech recognition quality is a product of data harvesting, the one thing Google does well?
- pjmlp 6y agoWhen speech recognition starts understanding European Portuguese without me playing stupid accent exercises, and mixed language sentences as well, then I will care about it.
- yyyk 6y agoI suspect access to a vast trove of user data is more important for ML than raw CPU power on the client.
- nmfisher 6y agoI'm just talking real-time performance and power consumption, not accuracy.
