[quotemsg=12754870,0,137290]I want more performance per core, not more cores![/quotemsg]
And ARMv8 does have better performance per core on top of wider registers and extra general-purpose registers to better optimize code with.
While this is true additional cores are still beneficial. Dedicating a core to, say, 3G/4G, another to background apps and another to the OS (Going by utilising an 8 core where all cores can be used at the same time, i.e. not the Samsung Exynos 8 core...) would leave more cores free to handle taxing applications. Albeit there comes a point where per-core performance negates the need for multiple cores somewhat, but mobile processors are not at that level at the moment.
[quotemsg=12757217,0,1303809]A few months back, Qualcomm dissed Mediatek about having 8 cores.[/quotemsg]
A few months ago, Qualcomm's (now former) CEO was laughing 64bits off too.
If all the other ARM vendors are going octo-core 64bits for their higher-end parts, Qualcomm has little choice but to go there as well or risk hemorrhaging market share by falling too far behind the progress curve.
