AMD versus Pentium4
I was going to build a new box with a P4 3.4 Ghz 550 Prescott processor. I know 'Why a Presscott? Well because I want to use the Asus P5AD2 Premium mobo that's why. I had hoped to overclock it to somewhere near 4Ghz...
Anyway the vendor pissed me off and said they shipped the order but only the video card showed up and *now* they say the mobo, cpu and memory is back ordered. Bastages! So I figured I'd try to come up with an alternative while I wait and decide if I should cancel the order or not.
The problem is I want to keep the vid card Saphire X800XT PCI-Express so I need to use a mobo that has PCI-E slot in place of a VGA slot.
The Nvidia nForce4 comes to mind but I don't even know which AMD CPU would be comprable to a P4 in the 4Ghz range.
So, what's the AMD alternative to a 4Ghz P4?
Of course all suggestions and flames welcomed....even Mobius

Well considering how soundly the top Athlon 64s smack the 3.6GHz around when gaming, I'd say get a 4000+(heh, duh) or a similar top-end Athlon 64/FX.

why stop there, Krom? For more money than you have, you can get a 96-processor opteron system. Or maybe you could move up a notch from there...

Not to mention heat your house during the winter without having to run the furnace. Just run a fan, and connect a hose from a duct to the fan and then from the fan to the back of the computer and you're set. You'll be cooling your computer Sickone style.Krom wrote:If you had 96 opterons running, you could emulate any video card you want in software.

The shocking truth about the P4-560 is revealed at THG:

Not really. if the Semprons where 64 bit they'd eat into the Athlon 64 market.
Anand article wrote:Unfortunately, in addition to the reduced amount of cache, all of the Semprons lack 64-bit support. That isn't a major concern yet, but it could be in another six months when we see the launch of Windows XP-64 and 64-bit applications. For those that are interested in 64-bit computing, you will want to spend the extra money for the Athlon 64.

Woodchip, I'm an undergraduate at school right now studying to be a computer programmer, and from what I've been told the reason for 64 bit is for larger memory address allocation. Not really for integer values because 2^32 is quite a large number, but mainly for pointer opperations.
See pointers are addresses to addresses. So it's an address that points to another address. I know it's very confusing, but when you program you'll have to learn this. The issue with a 32-bit system is that you can only have so many unique addresses before you're out of memory.
There is a reason why systems only allow for 4GB max. This is one of them. So it's 4GB per CPU as each CPU get's it's on 32-bit instruction set. Well for 64-bit we effectively double the amount of unique addresses so if I were to guess at this, we'll probably start seeing single CPU chips with a max of 8GB memory possible assuming that it will double in RAM but I'm making an assumption that it's 1:1.
Anyway off of all this crap, moving to a 64-bit chip isn't going to help you if you continue to run 32-bit programs, and this will probably be the case for a few years yet, but eventually if you don't have a 64-bit system you'll find that programs wont be able to run on your 32-bit system because you don't have enough addressing space or in other words they were compiled for 64-bit machines. You've got some time yet before that happens.
One last note though. A 64-bit machine isn't more expensive then a 32-bit Intel machine so not updating to one seems kinda prohibitive to me.

You need to do some more study I'm afraid:SkyNet wrote:Well for 64-bit we effectively double the amount of unique addresses so if I were to guess at this, we'll probably start seeing single CPU chips with a max of 8GB memory possible assuming that it will double in RAM but I'm making an assumption that it's 1:1.
"The AMD64 platform can address 4 petabytes of physical memory, and a 64-bit CPU can potentially address up to 18 exabytes."
4 petabytes = 4,096 terabytes = 4,194,304 gigabytes
18 exabytes = 18,432 petabytes.
fliptw - he stated that 64-bit memory addresses result in a doubling of maximum memory capacity compared to 32-bit processors. However, the difference is actually two to the power of 32 - several billion - not just two.
64-bit chips, by themselves, do provide no performance increase over 32-bit models; you have to write software for it. And it's mainly a precision/mem capacity increase anyway.
