AMD 2500+ Socket A CPUs Compared 227
SuperPuppy writes "Hardcoreware.net has
rounded up
three 2500+ Socket A processors from AMD. An AthlonXP, based on the Barton core
(this particular one predates the locked multipliers we've been seeing lately),
a Mobile Athlon, based on the Barton SOI, and the new Sempron, which is based
on the Tbred core. Each processor differs in clock frequency and cache size, but most
importantly, the Mobile Athlon takes up a LOT less juice than either of the
other two, and is therefore a remarkable performer in terms of overclocking. The
Sempron was quite disappointing on all fronts but price."

I'm quite fed up with these noisy computers. I have 4 of them at home, and except for the laptop, they all generate much noise, because they heat so much that every little piece, CPU first, needs a fan. I hardly can hear me think anymore. One of these systems acts as a server that I keep up at night. I did my best to make it go silent but I can still hear it behind the door.
In some way it means the same as another post right before mine: low power dissipation. This value has dramatically increased [erols.com] in the past few years, in the name of the top speed race, but at the price of our tranquility.
It also joins the view of anther poster that most users don't need the extra power offered by the latest CPUs. I certainly don't, so I'd rather use a quiet 1GHz machine than a noisy 3GHz one.
This is why I'm quite sad to see that you cannot easily buy Transmeta-based systems. This is exactly the kind of CPU I would enjoy, if only my online computer parts store had that available. What I am really looking for is a completely fanless system.

Most video cards don't need a fan at all, although passively cooled cards can still heat up the interior of your case. It's doubtful that you really need the absolute latest and most powerfull leaf-blower video card on your home server.
Hard drives and power supplies are the other big sources of noise. Hard drives noise is noticable because it comes and goes, while power supplies need to push all the heat that those passively cooled components have been producing out of the case. A well made drive seated on noise absorbing padding, rather than bolted directly onto a steel frame, can be reduced to a low, cricket-like chirping noise while large, slower case fans can take a lot of the load off of the PSU without raising noise levels significantly. Take a look around Silent PC Review [silentpcreview.com] for more on this topic, or just look for a retailer in your area [bigfootcomputers.com] who carries quiet PC parts [canadacomputers.com].

So what was going to be a relatively easy summary has now become a little bit more convoluted thanks to the extreme overclocking ability of the Mobile Athlon chip.
Basically in short we can conclude the following.
- If you're looking to run at straight out of the box stock speeds, then going for the Athlon XP 2500+ should be a no brainer. The XP either beats or almost matches the Mobile chip in every benchmark and can be had at a lower price
- If however you're a tweaker, a freaker, a mad cookie eater, then by all means spend that extra four bones that is burning a hole in your pocket and pick up a Mobile Athlon chip (and as you can see above, we found it for the exact same price as the standard Barton). Even if by some chance you get a dud in the overclocking department you'll still have a chip that can easily run at stock XP speeds all the while requiring MUCH less voltage which will enable you to have a quiet if not super fast gaming system.
- Finally, if you're looking at the Sempron do it only if you absolutely cannot afford that extra ten bucks that it's going to cost you to move up to a Barton based XP processor. Though admittedly marketed at the low end internet/email usage market, AMD 2500+ Performance Rating system just doesn't hold up here. With the return of the low end Duron-esque processor let's hope AMD moves to a new naming system so as not to confuse Joe AOL who picks up a Sempron 2500+ thinking he's getting a great deal picking up the newest AMD chip at a great price to expecting it to perform at par with the regular Athlon XP chip his twelve year old kid made him promise to get.
