true. A12 will be faster than A53 but when it comes to written spec, 64bit looks nice so most manufacturer will slap their mid-low end phone with A53 instead of A12. at least in ads they can show "now support 64bit Android" as if they'll get a 64bit Android OS update at the first place as most simply ship a 1yr old OS with another 1yr old update some 12-15months later.
i was actually going to write the same thing in the previous post but then i remembered an article stating that rockchip , allwinner cortex a12 are already in production ...
even mediatek will be launching them by 2h
Mediatek confirms LTE chip on the way along with new Cortex A12 chip : Gizchina.com
so there will be some chips out there maybe they might try implementing big.LITTLE with 2 cortex A12 with 2 Cortex A53
or cortex A12 might end up totally tablet only chips.. but mediatek will bring it to mainstream.. so that gives 32 bit chips a liitle bit more life..
PS: chips based on Cortex A7 took such a long time to debut from Qualcomm.
1) Comming to qualcomm why would qualcom use Cortex A12 ? the sole objective of ARM for bringing Cortex A12 was to compete against qualcomm krait .. cortex A7 is very power efficient but very weak also.. whereas cortex a15 is very powerful and power hungry , in fact in 2012 chipmakers were unable to make use of cortex a15 in smartphones it needed way too much power to run .. The reason qualcomm has been so succesful is because arm did not provide other chip makers an option that gives high performance at good power effecieny ..
that is why qualcomm developed their own krait cores . and were hugely successful because the competition was using older cortex a9 in 2012 . krait were a huge improvement over cortex a9 while being inferior to cortex a15 ..
Krait cores and Cortex A12 have exactly the same performance .. cortex a12 is made for other manufacturers other than qualcomm ..
2) regarding qqualcomm launching cortex 7 cpu so late ...
this is the part i hate most about qualcomm .. they all became cocky after acquiring the high end market , their initial plan was to keep using that cortex A5 junk , just increase the no of cores and serve those to the developing nations while enjoying massive profits instead of giving a reasonable performance with cortex A7 .. Cortex A5 Refused to get out of the market ..luckily mediatek rose from the Ashes and showed a middle finger to qualcomm
and launched their quad core Cortex A7 in november last year , while qualcomm quad core cortex A5 were still yet to come out in the market .. qualcomm was disrupted and then they announced in the december later that they will release cortex A7 cpu . while mediatek based cortex a7 devices had already started selling , qualcomm cortex a7 were supposed to come 1 year later .. and Moto G is their first device with cortex A7 .
Wonder if phonemakers are going to switch to Cortex A12 (should appear in 20-25k price range) or directly make the jump to A53.
I think they will go directly with cortex A53
a) A its Cheaper than cortex A12
b) they get marketing bragging rights
we'll have 2k screen that will require more than 2GB ram obviously. then maybe 64bit OS may come into play. for now its useless.
i guess you meant 4 gb , yes but that requirement will be in high end when note 4 launches with 4 gb RAm .. 4 gb ram in low end isn't comming for the next 2 years .. qualcomm moved to cortex a53 this time quite fast because they learnt their last lesson if they don't act fast mediatek will eat them up in the low end again .. smart move announcing it first
hope Google doesn't remove ARMv6 compatibility from its apps anytime soon.
Arm v6 ? who uses arm v6 now they became obselete 3 years go... if you are talking about arm v7 then no google won't remove anything at least not for the next 4 years
