    As of now, I can't think of a consumer device that would require 64-bit processors, much less use 4 GB of RAM. Until then, this falls in the "cool" category.

    Difference with Windows was that Microsoft had already a capbale, consumable operating system that would greatly benefit from 64-bit; but as for moible, we're not quite there yet.

    I use and need the 8GB in my laptop right now. I wouldn't even consider a new laptop that couldn't support more than 4 GB. Not only that, but ARM processors aren't limited to just the mobile sector i.e. NVIDIA's Project Denver. This falls into the "about time" category.

    Also, this story falls into the "old news" category as it is at least five days old.

    I was specifically talking about smartphones, not laptops, as it is clear there are 64-bit processors on laptops right now (which clearly contradicts what I said on my first comment, and therefore should have been obvious I wasn't referring to personal computers).

    Last time I checked Project Denver targeted computers, not phones. Regardless, I don't see how that is relevant to my comment, as I never said it wouldn't be useful for computers.

    Now we need a 64-bit version of Android. :p

    You said "consumer device"(s), which can be anything, and you also said "mobile", which laptops defitiely are. Specifically, I was saying that a 64bit ARM instruction set is not merely a "cool" vainity, but a necessary evolution. That's why I cited Project Denver, since ARM processors are not limited to only smartphones, tablets, or other such mobile devices. ARM processors will be running Windows 8, and I don't know about you, but I think 64bit Windows 8 on ARM to be a requirement.

    First and foremost, you might not know this, but you are embarrassing yourself. I'll show you why.

    First, even though I said the words "mobile", and "devices", that does not specifically include laptops. For two other reasons, but the first one is because of the context in which this article is based: ARM architecture. ARM processors are not used to power personal computers, but mobile devices such as smartphones, tablets, media players, calculators, etc.

    Second, project Denver is merely CPU + (Nvidia Tegra, maybe 'Logan') GPU on a SoC.That's about it. That due to this new architecture, the CPU is going to be 64-bit, does not, in any way, accelerate its development. So its not even "about time." It's nothing. Surely it is superior, but it in no way alters production for the better; to the contrary, it might slow it down if Nvidia plans to integrate Stark on it as part of the Denver project. Ultimately, however, all of that is about as irrelevant to this discussion as me talking about what I did when I woke up this morning.

    Thirdly, did you read this part of my last comment?

    "... as it is clear there are 64-bit processors on laptops right now (which clearly contradicts what I said on my first comment, and therefore should have been obvious I wasn't referring to personal computers)."

    It's clear I couldn't have been talking about computers, since, in my very first comment, I specifically mentioned I didn't know any consumer device that would require 64-bit processors. Assuming you, say, didn't even know about what I said in both my first and second point of this comment, it's still blatantly obvious I wasn't referring to personal computers, as 64-bit processors are pretty much the norm nowadays, thus leaving, unambiguously, mobile devices such as smartphones, tablets, etc.

    I could apologize about not being specific, but I think you missing all of that is far worse. Now, have a good say sir.
  8. lol I keep coming to this site and see this guy prtty much killing ppl with facts.. nice read. :D
  9. "...capbale, consumable operating system that would greatly benefit from 64-bit; but as for moible..."

    lawfer, you need to learn how to proof read before posting or retake 7th grade english.

    Should we add the above comments to an (un)official list of people who've gotten lawfered?

    I wrote that from my phone, one with which the susceptibility to error is often higher than desired. But here you go sir: Capable* and mobile.*

    Hopefully me fixing these helps you sleep at night now.
     
  12. Can you imagine? Run in a 64 bit version of Android? Full 4gb? That thing would fly. By that time Android 5 codenamed ice cream truck will be out lol

    And also dude @wagan8r, don't even bother anymore lol
  13. i can't wait to see what will power windows 8 devices. i wonder whether ios5 will still mop the floor with microsoft :)

    I thought lawfer was talking about smartphones....
  15. Now that smartphones support HD/HDMI, they can play 2D/3D movies. Just one of the movies will be greater than 3 GB. Besides the kernel normally takes 1 to 2 GB of address space and the applications take the rest.

    I was looking at an medical MRI on my old smartphone, but I was limited in size because of the lack of GPU power and the lack of memory. These two issues are being solved now.

    Another thing is Artificial Intelligence applications/tools. They use a lot of memory and processing power, which will benefit from 64 bit environments and they will not require the web to work like some other assistant apps do. Currently at work, we use workstations/laptops with 24 GB to 160 GB+ of RAM, and have used systems with 400+ GB of RAM, and will use more if they were available.

    Like they said, if you build it, they will use it...
