12292 Intel adds new ULV mobile CPUs to its line up

This one nearly slipped us by, but Intel launched no less than four new ULV mobile CPUs on Sunday, ranging from a mere 1.1GHz all the way to 1.8GHz. These are of course all Sandy Bridge based CPUs and we're looking at two Core i7's, a Core i5 and last, but not least, Intel's first ULV Sandy Bridge Celeron. Details of three of the models leaked a month ago, but now we know how much they'll cost as well.

This one nearly slipped us by, but Intel launched no less than four new ULV mobile CPUs on Sunday, ranging from a mere 1.1GHz all the way to 1.8GHz. These are of course all Sandy Bridge based CPUs and we're looking at two Core i7's, a Core i5 and last, but not least, Intel's first ULV Sandy Bridge Celeron. Details of three of the models leaked a month ago, but now we know how much they'll cost as well.

Starting at the bottom we have the dual core Mobile Celeron 847 which unsurprisingly is Intel's slowest ULV Sandy Bridge processor at a mere 1.1GHz. Oddly enough it's still a 17W TDP CPU despite having a mere 2MB L3 cache, no Hyper Threading and no Turbo boost and of course that very low clock speed. It's also worth remembering that Intel's Celeron and Pentium Sandy Bridge CPUs have inferior graphics to the Core i models.

Next up we have the Core i5-2557M which is a step up from the current and so far only ULV Core i5, the 2537M. Here we're looking at a dual core CPU with Hyper Threading clocked at 1.7GHz which is a 300MHz jump in speed over the 2537M. The top Turbo frequency has also been boosted from 2.3GHz for the 2537M to 2.7GHz for the 2557M, although the L3 cache remains the same at 3MB.

The first ULV i7 is the 2637M which end up faster than the 2657M, as this is yet another dual core 1.7GHz part. The 2637M also beats the 2657M when it comes to Turbo frequency as the older top of the range ULV part stops at 2.7GHz whereas the 2637 goes all the way to 2.8GHz.

The final CPU is the Core i7-2677M which is a 1.8GHz part with a Turbo frequency of 2.9GHz and at full Turbo speed it gets quite close to Intel's entry level 25W LV Core i7-2629M in terms of single core performance, although with a slower graphics clock.

Pricing is as follows in quantities of 1,000 units, Mobile Celeron 847 US$134, Core i5-2557M US$250 (the same as the Core i5-2537M), Core i7-2637M US$289 (the same as the Core i7-2617M) and finally the Core i7-2677 is US$317 (the same as the Core i7-2657M). Pretty impressive stuff for 17W TDP CPU's, now let's see some nice 11.6 to 12.5-inch notebooks that take advantage of the new CPUs.
