There are no LV or ULV i3s. There is only one i5 ULV (i5-2537M), the rest are i7s.
If I had to make a prediction, it would be i5-2537M for 11.6" and i7-2657M as BTO, and i7-2629M in 13" with BTO for i7-2649M.
Thanks for seconding what I said initially for three of your predictions, I went with Apple going for the i7s in all MBAs for similar costs. If they went for those CPUs for the 11", it
could reduce the price of the 11" MBA.
Current 1k unit price for the C2D processors are $262, $289 (
$27 diff) for the 11" and $284, $316 (
$32 diff) for the 13". If Apple simply replaced the CPU & iGP, they would have slightly more money for the SB CPU as it is combined. The CPUs I predicted for the MBAs were i7-2617M 1.5GHz ($289) and i7-2657M 1.6GHz ($317) at 17W for the 11" MBAs (
$28 diff). For the 13" MBAs, I went with the i7-2629M 2.1 GHz ($311) and the i7-2649M 2.3GHz ($346) at 25W (
$35 diff). This is about
$30 increase in CPU price, so if the 310M iGP costs a lot more to Apple, it could mean lower MacBook Air prices all round, or larger standard SSDs (more likely)
Additionally, Apple have been offering better value CPU upgrades for the SB platform. If anyone actually bought the 2.8GHz i7 (640M) 15"/17" MacBook Pro released 20th Oct 2010, they
paid $200 for something which was only
worth $14 more ($346 compared to $332) and was barely faster than the 2.66GHz i7 (620M),
$186 for Apple to install it (93% of the cost)! This time the 2.2GHz quad core i7 (2720QM) to the 2.3GHz quad core i7 (2820QM) is a
$250 upgrade with the actual price difference at
$190 ($568 compared to $378), a small upgrade again, but with
$60 for Apple to install it (
24% of total cost), it's a much better value-for-component-price upgrade if nothing else.
Finally, Apple has really helped Intel to
save face and launch itself back into the forefront of performance with its SB mobile processors as well as showcase its new I/O technology. I'm sure if Intel were going to give reduced component prices to anyone, it'd definitely be Apple. That can only mean one thing to me,
"SB all round please"
Those i7 processors draw 25 W, and would easily reduce the battery life of the MBAir 13" down to less than 5 hours. Is it really worth it?
Sorry mate, only the XXX9M SB mobile CPUs have TDP of 25W,
all XXX7M SB mobile CPUs have a
TDP of 17W, both the i5 and the i7s. Let's clarify what Hellhammer said earlier, TDP is Thermal Design Power and is the
maximum power of the combined CPU/iGP. In light-use, SB processors are much more efficient than their C2D cousins, so we expect to see better power usage then too.
Taking into account the
saving of 4-5W of maximum TDP, the
reduction of fan usage (not as hot so less power needed for fans) and the
light-use efficiency of the SB chips, expect to see
much better battery-life if these SB CPUs are adopted in the new MBAs.
Because processing power in the i7 magnitude is over-rated for most other tasks.
Mostly true, ULV i7s; i7-2617M 1.5GHz and i7-2657M 1.6GHz at 17W, are only better than the 35W i5 processors in efficiency, as the i5 35W CPUs are more powerful and have higher clocked HD 3000 iGPs. i7 doesn't always mean faster, it's only always faster compared to other i3/i5s in same TDP category. The 35W i3-2310M 2.1GHz on the other hand has no turbo, so will be beat by almost all ULV (17W) and LV (25W) i5/i7s
Thats what they said back in the 2009 refreshes, its just to cover up for the poorer power system. I still get around 7 hours of battery out of my '09 macbook pro 13", with many users reporting up to 10 hours or more with last years revision.
I call BS on Apple's claim.
Mate, not so sure about that one. New 13" MBPs are ~2W lighter on
max TDP and SB CPUs are much better at reducing power in light-use. I'd expect to see similar battery-life for performance use but better battery for normal use. We'll see when they get tested...
It's (almost) impossible to compare your battery-life with anyone else's unless you do exactly the same thing
which looked pretty plausible at the rate they were going.
