AMD Athlon VS Sempron

[tankz]

AMD Athlon XP (NOT Athlon-64) VS Sempron, which is better?

how? why? in what ways is it better?

AthlonXP and Sempron (socket-A) are essentially the same thing. AMD 'demoted' AthlonXP to Sempron and changed it PR to target Celeron (rather than P4). Therefore, AthlonXP xxxx+ is faster than Sempron xxxx+.

Not quite. some Semprons are socket 754 (definately the Sempron 64's are). So if you get a Sempron that's S754 it will have a FSB of 1600mhz and blister the heinie of that little XP.

Go Sempron!

My post was making a direct comparison between the two socket-A CPUs as AthlonXP is socket-A only. Sorry for not specific enough.

I don't see mine on that list; how does an Athalon 64 X2 4400 stack up against a Sempron?

very good

I agree with Willy's post. When Semprons were first introduced it was only available for Socket A. These were simply Athlon cpus demoted and rebranded as Semprons - however using an older Throroughbred 'B' core instead of their then fastest XP core Barton. Barton (512k L2) was simply too big and expensive, not to mention hot. The Thoroughbred 'B' (256k L2) is essentially a Barton with a smaller L2 cache. This kept costs down which allowed AMD to position these cpu's to compete against Intel's Celeron line (who also run on a 256k L2). Their Duron line of cpu's was then dropped - these used to compete against Celeron.

That said, for Socket A: AthlonXP (Barton) > AthlonXP (Throroughbred 'B') = Sempron (Throroughbred 'B')

Now for Socket 754, the first Sempron cpu's were non-64bit. These are no longer available as they have all moved on to 64bit Semprons. These are faster than their obsolete Socket A counterpart cpu's, but I won't get into the reasons why. Just look up the K8 architecture if you do.

LOL. I see the Sempron whimpering in the corner.

socket A semprons are slower than axp, socket 754 changed everything

As I said, the first Semprons introduced using the tbred 'b' core were only slower than the popular AXP's that were using the popular Barton cores. Sempron essentially was a rebranded AXP on Tbred'b'. Nothing I said was inaccurate.

AXP(Barton) > AXP(Tbred'b') = Sempron(Tbred'b')

I can also add that later Semprons which started using the Barton core were almost to just as fast as the AXP Barton counterparts (AXP had slightly higher clock). To clear the confusion, *basically* just think of AthlonXP's were renamed as Sempron. What counts most is the core it uses.

AXP(Barton) = Sempron(Barton) > AXP(Tbred'b') = Sempron(Tbred'b')
