As you can see, Sempron's frontsidebus is up 25% versus the lower XP-models which it is supposed to replace.
We leave it up to you to judge how much this accounts for increased performance. For the most careful conclusion, looking at the only Sempron model which clocks exactly as an XP-Model, the Sempron model number is 20% higher than the corresponding AthlonXP moniker.
We suppose AMD's spinners will come up with the explanation that these ratings are based on a scale based on some legacy reference-product, maybe like a Duron 1GHz. That's fine with us, INQ regulars know well where these rating arrows aim for anyway. So we just leave it up to you to make your own mind up whether these numbers will hold their own against Celeron Ds. ยต
