Does anyone see this as being a big deal? and if so whats the likely timetable that is does become relevant?
When Apple originally unveiled the Apple A7 64 bit chip I thought that existing 32 bit chips would become instantly obsolete.
But turns out that the mobile industry is in no hurry to get 64 bit and even when we do get 64 bit the abundance of 32 bit apps will not go down.
The main benefit of 64 bit is the ability to use more than 4GB of RAM considering phones don't really need that much, there isn't a huge benefit of 64 bit, just yet.
Nvidia does plan to release it's 64 bit Tegra K1 later this year but it's likely only going to be in tablets and not in phones.
Snapdragon plans to release it's 64 bit chips next year but they will be 8 core chips and since apps don't multi thread that much, there is no huge benefit.
I bought a 32 bit Snapdragon 800 device just over two weeks ago and I hope to keep the device for 1.5 or 2 years, let's hope it continues to provide a smooth and seamless experience even then.
Sorry for the long post.
