Definitely a useful table, but two additional dimensions I would really love to see here are cost, and power consumption per unit work, especially the latter.
Personay it's been crushing to me that Cortex A53 (2012) and A7 (2011, a slightly updated A5, 2009) have been around for so so so so long & still dont have a worthwhile replacement. A55 is out but debateably a 10% win at best, and the almost 2 year old A510 doesnt actually exist/isnt for sale. A7 has some A35s that maybe sort of compete.
I want to see what is changing over time, if anything. I never thought I'd be anywhere as thamkful as I am that RPi has seemingly singlehandedly forced some value delivery, some progress. I dont know that we'd be seeing things like A72's (2015) for under $100 otherwise. The low end market has been rough.
I think the problem with the in order designs is that there is not much to improve on. Most of the gains for OoO cored designs are coming from the branch predictor.
You mentioned A55 and A35. There are good boards shipping those cores, now. rk356x and various Amlogic SoCs come to mind.
The A55's have been around for a bit, yeah. They just dont seem to be noticably better as cores (but there's been ongoing gains in uncore). You may be right that there's just not much headroom perhaps. But supposedly the A510 and announced A515 offer some real gains.
I havent tried the A35. I see them as more targetted towards MID devices than the A7 was butb hats product-market segmemtation maybe.
Is that all from one author ? If the results are submitted by multiple people I'd imagine it would be hard as not everyone have setup to measure power usage accurately.
For anything battery powered idle usage also is useful stat but that I'd imagine would vary widldly depending on whether kernel supports all of the chip's power saving features
> whether kernel supports all of the chip's power saving features
I mean that is genuinely relevant info for you if you're gonna be using that distro. It doesn't matter what it supports in hardware if there's no software support for it, it's like it doesn't exist.
