It seems that just about every man and his dog is hankering after a shiny new Penryn-fitted notebook, so kudos to Dell for doing its bit to satiate the unwashed (and clean for that matter) masses. Dell being the smart company it is, the first notebook to receive the upgrade options is arguably the company's most desirable, the XPS M1330.
The base spec M1330 still offers a lowly 65nm-based 1.66GHz T5450, but upgrade options now include the 2.4GHz T8300, 2.5GHz T9300 and the 2.6GHz T9500. As you probably know, as well as the slower clock speed the former chip sports half the cache of the latter two, offering 3MB as opposed to 6MB.
Currently the UK site isn't actually listing the upgrade option, but Australia and America have both seen it so we feel it's safe to believe us Brits aren't too far behind. Price wise the T8300, T9300 and T9500 are $275 (£140), $400 (£200) and $675 (£340) upgrades respectively. Given those prices, the T9300 is probably the processor of choice for those after the improved specs of Penryn - nearly £150 for a mere 100MHz clock increase on the T9500 hardly seems the deal of the century.
Hopefully, with Dell's bulk-buying power and general good relations with Intel, the company has managed to secure a decent payload of Penryn chips to fill the inevitable demand. For those of you reading this in the UK and wanting to get in on the 45nm action, my suggestion would be to check out the store tomorrow by which time it should be refreshed with the new options. If you just purchased an M1330 with an older Merom chip, try not to be too despondent, you still bagged a great machine.
