40-bit does not equal 64-bit memory.

[JackAxe]

OK I've rambled about Athlons and Xeons being hybrids 64-bit/32-bit procs, well I was giving them tooooo much credit.

Here's what they can actually do, even the glorious "Opteron;"

40-bit physical memory, (1024 GB) 48-bit virtual memory. Nothing to sneeze on, but it's not 64-bit at all, where as a G5 can trully adress 64-bit memory. :p But I can't afford 16 exabytes of RAM, so I'll never be able to address the full range, nor does the hardware exist to allow me to do so.

Intel and AMD are not being truthful. If I would've looked some more, I would've noticed this a while back. They should call there chips XXX64/40/48-bit procs.

But anyways, thought I would share. ;)

Wasn't there someone here last year complaining that going all the way to 64bit was a waste of money and time? :)

Guess he's happy. :)

Darn, there goes my first petabyte system....

Hey, that wasn't me, it was probaby Shogmaster or was it Intel. :p :D

All I know is that 1 Terabyte of RAM isn't that far off for workstations, so the PC procs are going to need a whole new revamp in a few years. The G5 will also need to be upgraded to stay competitive, but that's one less thing IBM will need to address.

What in the world would you need 1tb of ram for. Maybe a full scale computer model of the entire planet, with full elevation data, and satellite imagery, as well as real time weather. And then maybe you could run a simulation on it for good measure. Anyway, 64bit desktops are not necessarily all supposed to access 64bit memory. I think that was Apples doing. 64bit means that it can execute 64bit instructions, and nothing else. The memory architexture is separate, though I believe that you do need a 64bit system for 64bit memory. Does anybody know anyone with 1tb of memory on a g5? There is only one way, AFAIK, that this could be accomplished in something smaller than a server array. You would have to use a different type of memory, such as Quantum Optical RAM. I wrote an article on it over at TamsPalm. You can get to it by clicking anywhere in this sentence. (http://tamspalm.blogspot.com/2005/04/non-volatile-ram-reality.html)

hmmmm.....
Satellite imagery:

The state of NM at 1m, 3color (most cheat by stripping to B&W), freely available as a download from UNM, 800gig.
The local range, at 1ft, recently flown, 750gig

The world!

Elevation data for the middle world (+60 latitude to -60latitude) at 30m, please note that although the ocean is at sea level bathemetry charts the ocean floor and therefore needs equal precision as surface elevations.

1042 gig

Same area of the world at 3color landsat 30m....

1564gig

Common Commercially requestable 3color satelite imagery 1 foot (or lower by limited companies).
Common Commercially requestable 3color fixed wing fly over 0.5ft (or lower by limited companies).
Common Commercially requestable elevation data 0.5foot (easily adjusted to 1cm)

weather
Assuming that a 30mx30mx30m volume of air can be correctly identified, mapped, and coordinated with every other similar volume of air to produce a sound and realtime true real-time accurate weather map (and it is unclear if even reaching 30mx30mx30m is sufficient to accurately predict weather) the necessary memory would be well into the 128bit computer's capability.

Our current weather models are only calculated at 0.5 degree increments because the processing power and memory capability is beyond 32bit for anything more....

The world is in desperate need of every ounce of processing power, every bit of any CPU that someone else can dream up.

[SamuraiCatJB]

Next time you complain that the weather man is wrong, don't complain to anyone here... You said we have no need for 64bit or better memory. I hear a lot of people bring up this wonderful "world" issue.... They obviously have absolutely no idea just how BIG the Earth really is.

SC pointed it out nicely. :p

And if you read my first post again, I "specified memory."

Apple actually made an analogy about the size of 32-bt in comparison to the world. If 32-bit filled an area the size of the Golden Gate Bridge, than 64-bit would be almost the entire planet. So 40-bit isn't even close. ;)

FYI, the current G5 can only hold 16 Gigs of RAM do to limitations of the current mobos. And that is why I stated this; "nor does the hardware exist to allow me to do so."

I would personally have troubles filling 1TB of RAM "at this time," but can fill up 16 GB of RAM like it's nothing right now. Even with just one app. But I'll settle for 9 gigs now, which I'm upgrading to for Tiger and CS2. This will allow me t0 allocate 4 G into Photoshop, which it needs and 1-2G for my other apps. And when AE Pro 64-bit is released, I'm upgrading to the full 16G. My 7-8 minute projects are reaching over 12 gigs in size on export.

Aah, youre a barbarian. I dont really care anyway. I only have my lowly P4 2.8ghz, with 1gb of memory. I dont do any kind of graphic editing, im just throwing stuff out. Power to ya if you can get your 1tb ram system. Have fun.

I have 1 G on my PC. It's primarly for games though and just a lil bit of 3D assistance work. :)

Go back 5 years and 1G of RAM was more then most comps could handle. At that time my home Mac could only hold 768 megs. Most of my images are bigger than that on disk now and occupy 2 - 3 gigs in RAM. Go back about 10 years and 1Gig was only found in the ultra expensive comps. Photoshop couldn't even see 1G if I recall correctly.
