" In case you missed it, Samsung only noted that the Exynos 5 Octa in the Galaxy S4 should be clocked at 1.6GHz and according to details the four Cortex-A7 cores are at 1.6GHz and 1.2GHz is for those four Cortex-A15 ones."
If you go to the fudizzla articel, the four A-15's at 1.8 ghz outperform the two core clovertrail by 10%. The article also indicates that the phone will run the A-15's at 1.2 ghz. This means the A-15's underperform the clovertrail by 20% in useable phone.
Merrifield will outperform clovertrail by another 100% with a reduction in power.
On the same manufaturing process, a doubing of performance noramlly results in a more than quadrupling of power. There are no performance/power improvements in the TSMC timeline until at least mid 2014.
It is impossible for ARM to keep up.
The ARM fans now say that performance doesn't mater. Than why the big/little? Why 64 bit?
Pain is coming to ARM fans soon.
