Celeron or Sempron

First you will need a Welcome to the Computer Forum! http://www.computerforum.com/70672-official-welcome-thread.html and a reminder given to all new members to review the http://www.computerforum.com/52038-forum-rules.html
AMD held the performance edge over Intel for several years by seeing more work done per cycle with the front side bus(FSB) then Intel. Intel spent that time working with faster cpu clock speeds. The older AMD models ran circles around Intel's lineup until the Core 2 dual core models focused more on the newer Hyper Transport and fsb. Currently that's what is now giving Intel the slight lead over AMD.

Your coming up with some good ones here, I would (REALLY) like to see these Core 2s that are running on Hyper Transport!!

What Celeron are we talking about here? Pre Celeron D? I hear some of the more recent ones are pretty darn fast and overclock well. But yes, many of the earlier Celerons were just junk!
Yea it really dependes on what Celeron your talking about, but as far as the Sempron, if it a 745 or AM2 it gets help from its pipelines, onboard memory controller and Hyper Transport.
It's a socket 478 one, not sure of the model. I take it if I upgrade to this, it'll run rings around the Sempron?

LOL HOLY COW, yeha it should do but dont pay £120 FOR IT!!! ROFL
You can get them for like £40-£50 now lol

I know lol, I saw it myself as a rip off...that place is usually pretty good value...

The word 'Celeron' is pretty unspecific, it's just the name that Intel gives to budget models of their Pentiums.
As for why the Sempron is faster, to put it how you might understand it, clock speed (Ghz) hasn't really been the determining factor for how a CPU performs for quite a while.
One Hertz (Hz), or 1/1000 of 1/1000 of a megahertz (Mhz, which is 1/1000 of a Ghz), simply just describes a cycle a second. Intel CPUs, while they may have performed more cycles per second, did not do as much work per cycle as similiar AMD CPUs, which is why the Sempron performs better.
This is also why AMD has shyed away a little from using Ghz to describe the CPU, and now uses series numbers. For instance, the '2500+' after the name of you Sempron means that the processor should perform at the same speed as a similar Intel CPU at 2.5Ghz.
Hope this helps you understand it a little better.
The actual term is Hyperthreading. But you seemed to have missed that one.
No I saw it, you missed it by calling it Hyper Transport!
Your Words!
Core 2 dual core models focused more on the newer Hyper Transport and fsb.

There are lots of different Celerons... what ever they advertise it as is what it should show up as... .3Ghz is too much to lose.

Celerons were always crap, since the first one release in 1996, the cheap versions of Pentium II, they didn't even have L2 cache. Now celerons are cheaper versions of the Pentium 4 CPU (Prescott) with em64t. Pentium 4 cache is normally 1mb but celerons are only 1/4 256kb. The celeron has wasted clock speed and not enough cache. Athlon 64's have an 512kb cache so half of it doesn't degrade as much performance as the Celeron D.
With the Semprons they have a 128mb L1 cache with a 1mb L2 cache on the higher models while only seeing a 128mb L2 on the low end. The middle models were the one seeing a 512mb L2 for the 754 line of cpus. You can compare each of those at http://www.amdcompare.com/us-en/desktop/Default.aspx
No Semprons have 128MB of L1, No Semprons have 1MB or 512MB of L2!!
All Semprons 754 or AM2s have 128KB of L1 and 128KB or 256KB of L2, your not even close on this one!!

That "m" key must have stuck again. Thanks for the catch! I'll see the MS Vista update gets put on again as well as a keyboard duster.
That M key somehow got the 1 and 512 wrong on the L2, since no Sempron has over 256KB L2

Not all celeron D have 256KB cache
Some of them have 512KB cache like this one
