Apple’s MacBook Air cannot support the recently launched Intel Ultra Low Voltage i3, i5 and i7 processors.

Intel, the biggest manufacturer of motherboards in the world recently launched its new range of motherboards in the category of Ultra Low Voltage. Amongst the launched motherboards, the range includes highly powerful i3, i5 and i7 processors with varying processing speeds and enormous ultra boosting powers. Being powerful motherboards still don’t make a cut to fit into the new range of Mac Book Air. It is not only a bad news for Intel but also dismay for Apple’s Mac Book range, as it was planning to upgrade its range of AIR notebooks with faster processing. Apple was banking on Intel to come up with processors to fit into their note books, but now they are left with no good choices.

Amongst the range provided by Intel, the closest to fit into MacBook Air would have been Core i5-540UM, which has a nominal speed rating of only 1.2GH. This is much lower than the current MacBook Air’s LV Core 2 Duo at 1.86GHz or 2.13GHz. Intel’s i5 processor can boost a single core up to 2GHz when conditions are right for turbo boost. So when both the cores are boosted in prevailing suitable conditions there will be performance advantages existing on certain hyper threading friendly workloads even when running at a lower clock speed.

The current Mac Book Air runs on Core 2 Duos which runs with 6 MB memory cache while the 540 UM i5 processors run on a memory cache down to 3 MB, which is disadvantageous. The reduced memory cache is may be the reason for availing such hyper threading and super boosting.

Though the Apple may do away with the lower memory cache and may take the issue as secondary, but the main problem is related to graphics. The myriad range of Intel processors inclusive of the latest ULV processors comes with a fade lower graphics of Intel HD, which the Apple can’t accept. As it can never be compared to what Apple is currently offering that is NVIDIA 9400M integrated graphics.

Trying to fix away all the problems related to graphics and lower memory cache, Apple is trying to fix in a discrete Mobile GPU and also use its switching technology. But the problem occurs when the size of the motherboard has been made after the change is twice the size of the motherboard currently fitted into the available Mac Book Air. This only means that Apple has to still be stuck on the old fad of Core 2 Duo’s and not offer the public with any upgraded Air’s.

Other than offering a performance boost by giving away four GB of memory RAM, Apple has the only of option of settling its issues with NVIDIA to RAM in NVIDIA 320 and come up with a gripping product in the market.
