32-bit or 64-bit? 12.04.1 or 12.10?

[VeeDubb]

It's called amd64 because AMD was the first to market (by a wide margin) with a 64bit CPU aimed at the desktop market, and thus became the standard. It is for all 64bit x86 processors, regardless of whether they were made by AMD of Intel.

Oooooooooouuuuuuuuu!!!!
amd64 means intel 64-bit???? What a surprise!!!!
or
Just Ubuntu till now not supports 64-bit hybrid intel system??
That's why they are recommending 32-bit version while downloading Ubuntu 12.04 LTS??

One information:
My system (previously described) was came with pre-installed 32-bit ubuntu 10.10. Why???? Why the dell people did not provide me 64-bit ubuntu?? Because I guess there is no 64-bit ubuntu distribution for modern intel 64-bit hybrid system.

Please correct me with reasonable information (link, citation etc.), I'm not fighting with you.... you all are my friend, I think....

You're over-thinking this by a factor of 10.

adm64 does not mean intel 64bit. It means x86_64bit.

AMD just happened to be the first to put out an x86 64bit CPU, and the name stuck. There's no more or less to it than that. It's just exactly the same as the people I've known since high school who still call me Steve, even though I prefer Stephen. Another example would be band-aids. Band-Aid is a specific brand of adhesive bandage, but since they were the first to be widely marketed, we call every adhesive bandage in the world a band-aid regardless of whether or not it was sold by Johnson & Johnson under the brand name, "Band-Aid."

It's just a name. You don't need a different version of Windows for an Intel CPU than you need for an AMD CPU, why on earth would you need a different version of linux?

If you need articles, try wikipedia, which clearly states that amd64, EM64T, and x86_64 are all the same thing.

There's also the article at help.ubuntu.com on the subject, which also makes it pretty clear, and states that, "Each manufacturer has a different name for 64-bit, such as: AMD's AMD64 and Intel's IA-32e (later EM64T). We use AMD64 to refer to all implementations."

Of course, it's also worth pointing out that I have two Ubuntu machines in my home running amd64, one of them is a quad core AMD Phenom II x4, the other is an Intel Atom D330. I'm running AMD64 on a 64bit intel CPU right now. Well, not technically 'right now.' I'm using my desktop. But I was watching Hulu on the netbook a couple hours ago...

As for Ubuntu recommending 32bit, I've said before, and I'll say again (but for the last time in this thread), Ubuntu recommends the 32bit system because it works on 32bit AND 64bit CPU's, while the 64bit system only works with 64bit CPU's.

That means that when your average Joe who has no clue what kind of CPU is in the piece of junk desktop they bought 4 years ago from Dell decides to try Ubuntu, they can download the 'recommended' version and know that it will work with their CPU, without having the discussing that you and I are having.

Anyway, it does not matter in any way whether your CPU was made by AMD, Intel, or VIA in terms of support in the amd64 kernel. It's just a name.


As for your hybrid CPU, they'll function without some of the bells and whistles with ANY operating system, and all the snazzy throttling and sleeping cores are fully supported by kernel 3.6 or later, which Ubuntu has. A 30 second google search will confirm it if you still have doubts.

64bit and 12.10

If your computer is 64 compatible you should be running 64 bit (unless you happen to have a very limited amount of ram, in that case 32 bit may run slightly better due to lower memory usage)

No, if your computer is 64 bit compatible... you should be running 64 bit. If you have less than 2 GB of RAM, then maybe not.

Folks, 64 bit Ubuntu is fully mature. There is no need to fear it. Some posters opinions here are very outdated and misinformed about issues with 64 bit.

Virtually all current desktops and laptops are sold with 64 bit OS's these days (usually Windows). So unless you want to keep living in 2002, go with 64 bit.

64-bit!? I still haven't migrated off of 16-bit!

That's literally exactly what my post said...

EDIT: NVM didn't see my typo, I had put 32-bit where I meant to write 64-bit, I was so confused when I read your post

You were totally correct.... after your edit...

VeeDubb, your post is very informative.

You're over-thinking this by a factor of 10. adm64 does not mean intel 64bit. It means x86_64bit.

After reading your post & searching around the web surely I'm now over-thinking about it by a factor of 100 not only 10.
Thank you Mr. Steve for giving me some light of knowledge.
