So in other works the Althon 64 is a beefed up Althon XP

<{POST_SNAPBACK}>

Athlon64 is sort of the next generation of the AthlonXP.

It has a nubmer of new features (the important ones being SSE2 and the memory controller on the CPU) that give it a pretty good speed advantage over an AthlonXP of the same clock speed.

But there are no radical departures from the AthlonXP architecture.

AMD64 FAQ

"Q: What is AMD64?

A: AMD64 is AMD’s 64-bit platform that extends the industry-standard x86 instruction set architecture and defines a new class of computing. The AMD64 platform is the first designed to deliver compatibility with existing x86 solutions and world-class 64-bit performance. The award-winning AMD Opteron™ processor for servers and workstations is the first milestone in establishing this new class of computing. The AMD Athlon 64 processor family will allow pervasive adoption of the AMD64 platform for desktop and notebook personal computers."

The 64 in comparison to the XP is like (not according to speed but progression) like The Pentium 3 and Pentium 4. It's a newer "line" (I'm not sure if that's the right word) of chips just like dual core AMD's are newer than the 64

64's are better than XPs not because of the 64-bit capable architecture but the superior engineering. It's just a faster chip.. there's really no need for 64 bit processors right now but in a few years when the 64bit market is up you'll see a noticable climb.

Bafore the Athlons, AMD named their IA-32 line Kn where n was some integer. So preceding the Athlon were the K5 and K6. The Athlon was going to be called the K7, but somone in marketing decided that if Intel was using bizzare names like "Pentium" rather than meaningful numbers, then AMD should do the same. And so K7 became the Athlon. The XP and MP were also K7s, just better ones.

The Athlon64 and Opteron are basicly the K8. There is a lot more to them than just the AMD64 instructions. In fact you should ignore the extended mode as it will do absolutely nothing for a normal user but cause trouble. Just think of it as the next AMD IA-32 processor family and you should be fine.

Ok another question when a Althon 64 says its 3200+, 3400+, etc that means its equal in speed to a pentium 4 3.2?

<{POST_SNAPBACK}>

yes,

no,

maybe a little a but don't use it as a guide.

all valid answers.

Back when P4 was released and starting ramping up clock speed, AMD started their "PR" ratings for AthlonXPs

They *said* it was in compraison to a Tbird core Athlon.

It was *apparent* they were meant to compare with P4's clock speeds.

At this point, P4, PM, Athlon64 perform very differently in any two different tasks.

An Athlon64 (and PentiumM for that matter) is a great chip for gaming, a 3500+ will hang around with a 3.8ghz Prescott 2M, or a 3.73ghz P4EE.

They're not so good for video ecoding.

Throw a nice SSE2 optimized, multithreaded video ecoding program at them and a 3.2ghz Prescott will probably take the cake over a 3500+.

Don't rely on those ratings to tell you anything of value.

Look at benchmarks, specifically those dealing with applications you'd like to use.

Oh so very true, don't play the number game on the CPU, Always do as Freidog has suggested when deciding what would work for your needs

The main thing my althon 64 will be doing is gaming.

<{POST_SNAPBACK}>

This is as good a comparison as you're likely to find. Notice that, for example, in the Doom III benchmark an Athlon 64 3400+ is a dead match for a 3.8 GHz Pentium 4.

The performance advantage you would see on the P4 would not be very extreme. Especially if the A64 in question is an A64 X2.
