Can someone explain 64 bit vs 32 bit in basic english?

Are you kidding? Apple has a 64 but processor and so their pictures are better???
That is so idiotic
Pray-tell what processing systems are available on 64bit processors that that aren't available on 32bit systems?
Also Apple DOESNT use subpar camera hardware. Their custom made Sony sensors are inherently more sensitive due to the design.
You are spreading misinformation.
This pisses me off
64 bit is required for 720p at 240fps in a 7.1 mm frame.
----------
A 64 pit processor.
Says who?
Are you saying that 32 bit can do it elsewhere? Then 64 bit isn't exactly required is it then..?
What's next? 64 bit is required for Facetime in a 6.9mm frame?
If you wanted FaceTime to be in 2k or 4k then yes it would REQUIRE 64bit.
What phone do you have?
Source?
So 720p @120fps is no problem with 32 bit, but double the frame rate and it suddenly REQUIRES 64bit?
Are you telling me that the Panasonic FZ-1000 is a 64bit camera? Are DSLRs 64 bit because they have better dynamic range, color accuracy, and white balance? Hint: No they aren't.
You guys keep saying that XYZ can't be done without 64 bit. Don't just spout buzzwords and state things without backing them up. Prove it.
DSLRs have dedicated hardware with specially tuned operating systems. You "prove" it as you keep telling others.
You're whole premise is flawed. For desktop technology I am not going back to 32 bit. For mobile phones once Apple hits the 3 gig Mark in memory they have little or no software modifications. I'm thinking they see that coming sooner rather than later.

So what? Are you now saying that you don't need 64bit hardware?
You guys were the ones claiming that 32bit technology cannot do image processing well and that 64 bit is REQUIRED. You guys were also claiming that most of the image quality improvements 5->5s are from 64bit and not sensor or software improvements. You guys tried to claim that slow motion video was exclusive to 64bit.
None of your claims have been followed up with any facts and it seems like you guys are flip flopping between 64 being required and 64 not being required (DSLRs, slow motion vid). I'm calling you guys out on spreading misinformation.

It should be obvious that 32 bit is plenty sufficient. This is the Nikon processing chip in their latest DSLRs:

ARM Cortex-A5MP - this is ARM v7. Definitely 32bit.

My entire premise is that the following is a HORRIBLE example of 64bit being an advantage over 32:
Nobody has backed that up in the slightest.

64 bit is not about more than 4GB ram! When will people understand this basic stuff? And how come that that is the only thing people have drilled in their heads?
----------
Why do you keep spreading BS when you are clearly misinformed on the issue?
Since you said in basic English. Here it's a comparison to give You an idea.
You have a car that can go up to 200mph. The entire world is a school zone with a Max speed of 15mph though.
That's having a 64 bit processor with one gb of ram.
Worst analogy ever.
----------
Seems like you don't understand fundementals of computer hardware and operating systems.
And your proof is where?
----------
So tell me where I'm wrong and back it up. I've given plenty of evidence that 64bit is not required to produce good pictures or take slow motion video. I'm not wrong about the camera until you show me that I am. This is not an unreasonable request.
To be clear, I am contending that 64bit is not required for anything the consumer sees. The 64bit pathway is faster, but that doesn't mean that there aren't other ways to get that speed. You guys seem to think that it is the only way.

I'm typing from it right now.
The iPhone 6+.
I'm starting to doubt that you even have an iPhone.
Based on that "proof," I could say that 64bit maxes out on 8mp pictures. We [should] all know that isn't the case.
You have brought no proof to the discussion.
If you don't believe that I use an iPhone 6 (and have used the original, 4, and 5, each for 2 or more years), check the EXIF of this picture.

64 bit processors, based on design of course, have instruction sets that in general are twice as wide as 32 bits to be executed in the equivalent number of clock cycles. This allows more freedom in the programming. and end user doesn't always see an individual improvement in one application. You're example of slomo is a good one because it shows android can handled a CPU intensive task. It's a matter of time before android is 64 bits because of the greater freedom allowed in systems and applications development.
I agree with everything you said here and have never said otherwise in this thread.
ARM v8 is faster and allows different choices when comparing identical designs/pathways. But that doesn't mean the ONLY way to do that is to go 64 bit, as people in here have been claiming. Android devices have been going with higher clockspeeds and more cores. Just a different design philosophy.

True, but the world is going 64 bit and I'm sure there are 128 bit designs in the works. You can't even buy, or difficult to buy a 32 bit computer. I also apologize for being snarky before, doing this at 40000 feet on a very turbulent flight. #
The image processing that really matters is further under the hood than the camera app, but it has nothing to do with 64 bit. You wouldn't digitize to 64 bits per channel, because that goes beyond the tolerance levels of the underlying hardware. You would just digitize additional noise. On image data that has already been quantized in some manner, they may hold it as half or full precision floats prior to conversion to byte length integer types. There is absolutely no reason to use double precision data, because even the original quasi-linear input data can't be trusted to that many digits of precision.
64 bit processing is not required for slow motion video, or to have a better photo. Both require lots of processing power, just like 4K recording and playback does, but it is separate from 64 bit. The processor in the iPhone 6 is faster in every regard, it has the capability of faster slow motion recording simply by being a more powerful processor. 64 bit doesn't make it more powerful.
I agree. Benchmarks will show a difference, but as we know from Android vs iOS, benchmarks aren't the deciding factor in real world performance. Many of the upgrades in processing power are not specific to 32 vs 64 bit, and even if Apple still had a 32 bit CPU every new CPU will be significantly faster than the previous generation.
Apple seems to think their users always think higher numbers are better. It's why they always mention they have a 64 bit CPU over 32 bit in Androids, they make a point to tell everyone how many transistors are in their CPU, and they love graphs that show growth with #x times more performance than last year. Yet they leave out battery size, RAM, etc. since they are relatively low.
