If working on branch predictors does not impact the user experience, then arguably that work is meaningless in the context of building real products -- it may still be interesting for academic purposes.
- fasouto 10y agoBranch predictors made the phones faster and this affects the user experience. But if you want to test the performance of branch predictors you have to compare similar things, you cannot benchmark two different OS and apps because you get and OS and app test not an processor test.
- woliveirajr 10y agoI think the point that previous posters were making is that in controlled environments some features might outperform others. And yes, the scientific way of testing things is isolating variables and changing one thing each time. But, for the final user, it doesn't matter if each technology alone is better than another. If you have a background 64-core processor, driven by another 8-core... What matters is how fast something loads, performs, and how long batteries last. Of course, this might be outplaced in a thread discussing NN branch prediction.
