the problem is that many low-end and middle-end android tablets are based on Cortex A53 which is a slow in-order CPU (but very power efficient).... The Flash storage performance is also very important for user experience and is often left behind in reviews
- gsnedders 8y agoAnd what's often an even bigger deal is many of the low-to-mid end devices have very, very little cache (some have no L2 cache, even!).
- monocasa 8y agoWait, what? I'm trying to think of an application SoC from the past 8 years that doesn't have an L2 cache.
- gsnedders 8y agoI'm struggling to find the one I was thinking of, maybe I'm just imagining it. Most things I can find are 256kB/core, which is the same as most Intel chips (though the A11 is over 1MB/core!).
- monocasa 8y agoYeah, you borderline need an L2 for any multicore systems. L2's main job on most designs is coherency and reducing the explosion of bandwidth needs from the cores all vying for the main memory bus.
- gsnedders 8y agoYeah, I was amazed when I was told it before. Obviously should've checked their sources. :)
