Please do not even touch the arm cortex-a15.
It is the worst design that arm has ever done!
Let's take tegra4 as an example.
This powerful chip is made by 28nm Lp, it has quard-core arm a15 cpu, and a Gefore ULP gpu.
It seems to be nice to have such an powerful soc, but its power consumption...
Let's say as the title.
I'm thinking about get an open pandora recently.
As both rebirth pandora and 1Ghz pandora has 512MB RAM,
do I still need to buy the 1Ghz version?
omap3530(600Mhz) VS ti DM3730(1Ghz)
ddr 333 VS ddr 333
sgx530(110Mhz) VS sgx530(200Mhz)
How the speed&battery life...
