Why did Apple create a 64 bit processor without increasing RAM?
Forgive me if I'm completely misunderstanding this; I'm trying to grasp the concept of 32 and 64 bit processors. If I'm correct, the difference between the two is that a 64 bit can process considerably more amounts of system memory, both faster and more efficiently than 32 bit processors. If this is so, why didn't Apple increase their ram to more than just a gigabyte? I know we currently don't really need this much power in a smartphone yet, but doesn't this render the fact that Apple made the iPhone's chip 64 bit practically useless?
While 64-bit addressing can allow more RAM to be handled, it's not the only reason to do so in a chip, no.
You didn't mention the specific processors, but I'm assuming you mean the Apple A7 design, which in turn is based on the ARMv8-A? Then you'd want to look at the AArch64 features to see what it offers.
- Why is my eye degree increasing fast when I'm not even doing anything? I play some computer but just 2 hours one day per week and I use some iPhone but not too much and I look at green plants and all that excersise past eye degree: left:300 right:325 now: left:350 right:425
- Why are Apple still using dual-core CPUs and 1GB of RAM? Other top of the rnage phones like the S4 are rocking a 1080p 5"+ display, 2GB of RAM and a quad-core CPU and yet the iPhone 5 and 5s do not even have a 720p display and are still are dual-core and 1GB of RAM.
- Which is faster? A6 processor from apple, or 1.4 quad core Exynos? I want to know which one is faster, the appale iphone 5's processor (A6 ARM from apple) or the galaxy S' (1.4 quad core Exynos)?
- What is the difference between 32 bit and 64 bit in the iPhone 5S? I was wondering what is 64 bit and why does it matter on an iPhone? What makes it different than the iPhone 5 or any other smartphone right now, and should we really care?
