i can see the s2 falling a bit behind when it comes to that stuff but it just seemed that samsung really thought everything out with that phone. Everything was perfectly optimized.

Great work by ARM and Samsung. :)

Those of us with the I9500 Galaxy S4 and Meizu MX3 owners may get the HMP function in a software update later this year, according to Meizu:

I doubt it for the S4 gt-i9500 ones as it uses Exynos 5410.
As far as I'm aware it's only possible for the Exynos 5420, but not for the Exynos 5410, where the CCI-400 coherent bus interface was either buggy or inexistent (the part of the chip that communicates the A7 to the A15 clusters) causing that to move from one to the other all the caches had to be flush.
If Meizu MX3 uses the 5420 then yes, it's a matter of a software update.

Thanks, I'm aware of all of that, what makes Meizu's statement intriguing is that the MX3 uses the Exynos5410 like the I9500.

It looks like I may be in the wrong here

But let´s wait and see as I´m not that sure it´s possible.

Well, let's see if Anandtech and Andreilux is right about that CCI-400 issue. Not really keen on all 8 cores to work at once but more interested to know if HMP mode can be enabled just by software update on Exynos 5410.

Think they'll incorporate LTE cause I'd like to see this in the US
