amd 64 bit chips

Thanks to its ideal configuration and use of the best components, the P4 3.2 in the Extreme Edition (actually a Xeon labeled 'P4') wins the performance crown. Its former gaming weakness against the Athlon 64 has been ironed out by the 2 MB L3 cache. The AMD Athlon 64 FX-51 is only marginally slower. Especially with 3D games, both the 1 MB L2 cache as well as the fast memory access (HyperTransport) help it decisively beat competitor Intel P4 3.2 (standard edition).

To see a major difference, people will need to wait for software that takes full advantage of 64 bit proccessing.

64, 96 and 128 bit OS's hare already in use; the Hitochi Processor is 128 bit and great for games, but that's about it!!

The nice thing about 64 bit and higher is that we can finally weed-out MicroSoft ^^

Uh, it doesn't matter what the OS and processor can do if the software isn't programmed around them. I doubt you would be able to play any games on a new processor built around purely on a 64 bit architecture.

My company is getting an AMD 64 computer and myself and the other people in my department are going to give it a test drive. Is there anything in particular anyone would be interested to know about it? I can add it to an informal to do list.

When windows 64 comes out I doubt the P4 EE will maintain it's performance crown. And also try to remember, the athalon 64's are going to keep getting increases in clockspeed. They have a future. The people at intel are fighting to get higher clockspeeds for the P4 and are barely getting anywhere. The Prescotts are getting 64 degrees celcius at stock speeds and perform worse than the existing chips at the same clock speeds. So while the P4 has the crown for the time being this victory is going to be short lived. As clock speeds increase and 64 bit software gets released the Athalon 64 is REALLY going to shine.

64 bit processing will be great fot making AMV's and in Animation Modes . but
if feels like its too little - too late!

What I mean is; if anyone can remember the days when the Radio Shack Model 1
was king, we had a 4 meg 8 bit processor and a 150 baud modem - now its
3.5 gig processor and a T1 connection ( we haven't changed in 30 years!! )

why?

the only differance between 30 years ago and today are how we display the Graphics!

Post-it, your avatar is kinda fuzzy. Try sharpening it.

neway, btt,

don't forgot that Intel may have an ace somewhere, but if that's so, intel sure is stalling for along time.

this is the article with a link to the site where the prescott was benched.

and this is the screen of the temps it was getting.

I have read everything, but I figured I'd reply since I work for AMD:

1) Windows XP 64-bit is in Beta-testing now and you can get a copy if you ask them. That would sort of imply that 64-bit Windows will be out sometime early next year ne? That would mean you could make use of your 64-bit processor as well. At the same time, as someone said, it's x86-64 meaning it has good 32-bit performance (comprable or better than the current P4 line) so you don't have to worry since you'll be fine until the 64-bit migration. That was the reason we went that dual compatibility route. So YOU could decide when to change.

2) Intel's Prescott *AVERAGES* 104 C and will require all of you to get new cooling solutions. Intel has already admitted this and some get as hot as 120 C. On average I think ours are around the 60's or maybe 80's. Everyone talks about us being the "hot" chips and yet Intel dissipates much more heat and power (Power ~ Heat).

At the same time, I hear they have a lot of improvements with the branch predictor and adding SSE3 (which they did on purpose...just a few instructions).

Intel has also finally admited that Megahertz doesn't mean jack shit. As someone said earlier, it'll be hard for them to even hit 4 Ghz and they need to now admit that Megahertz != performance since they won't be able to deliver on it. We've been saying Megahertz != performance the whole time. I think the Centrino/Pentium-M is another case of this since it's "slower' in megahertz, but better performance than the P4-M which has a faster core.

I'm rambling...

Err..I meant to say

"I HAVEN'T read everything" in my previous post...sorry about that...must be tired or something.
