mobile sandybridge Intel planning three more mobile ULV CPUs

Currently Intel has three ULV mobile processors in its line-up, but it looks like that will soon be expanded by an additional three model. We're talking about 17W TDP mobile Sandy Bridge chips here and very possibly the ones that will appear in Apple's upcoming MacBook Air refresh. The new models are said to include one Core i5 and two Core i7 models.

Currently Intel has three ULV mobile processors in its line-up, but it looks like that will soon be expanded by an additional three model. We're talking about 17W TDP mobile Sandy Bridge chips here and very possibly the ones that will appear in Apple's upcoming MacBook Air refresh. The new models are said to include one Core i5 and two Core i7 models.

Intel's current models are the 1.4GHz Core i5-2537M, the 1.5GHz Core i7-2617M and the 1.6GHz Core i7-2657M. The Core i5 differs by having 3MB of L3 cache versus 4MB for the Core i7's and it also has a slightly reduced set of Turbo multipliers. However, Intel's new models are upping the game a bit, especially the new Core i5 model.

We're looking at a base clock of 1.7GHz for the Core i5-2557M which is a massive step up in this market space and on top of that Intel has given it near enough the same Turbo multiplier as its Core i7 sibling. Oddly enough Intel decided to clock the Core i7-2637M at the exact same 1.7GHz as the Core i5-2557M, although the Turbo speed for a single core is 100MHz faster at 2.8GHz and it does of course have 1MB of extra L3 cache, just like the currently available model. What we don't quite understand is why the Core i7-2637 has a lower model number than the Core i7-2657M, as the CPU is faster both at base clock and at its fastest Turbo speed.

Finally we have the Core i7-2677 which is a 1.8GHz part with a Turbo frequency of 2.9GHz and it's the fastest ULV Sandy Bridge CPU for the time being. All three models have the same base graphics clock as the current models at 350MHz, but the max dynamic frequency is much higher on all three models at 1.2GHz, compared to speeds between 900MHz and 1GHz. No word on pricing as yet, but we have a feeling that it won't be too long before we see some new ultra-thin notebooks with these CPUs fitted to them.
