Geekbench scores coming in on 13" and results are... crappy?

[Dan--]

The benchmarks are coming in on the mid-2012 13" Macbook Pro, and they seem to be a little, err, underwhelming.

I'm not entirely sure how to translate the linked scores into a single number, but they seem to show the following:

Model           Chip    Cores  Threads   Speed    32-Bit Score
New 13" MBP   i5-3210M    2       4      2.5GHz      6822
New 13" MBP   i7-3520M    2       4      2.9GHz      7883

This is not much better than the ultra low power Airs, despite the same numbers of cores, threads, and significantly higher clock speeds:

11" Air       i5-3317U    2       4      1.7GHz      5784
13" Air       i5-3427U    2       4      1.8GHz      6175
13" Air       i7-3667U    2       4      2.0GHz      6928

And hardly any better than last years 13" MBP:

'11 13" MBP   i5-2435M    2       4      2.4GHz      6128
'11 13" MBP   i7-2640M    2       4      2.8GHz      7219

Any idea why we're not seeing a corresponding bump in speed over the Air's based on clock speed? I was expecting/hoping for scores about 25% higher on the new 13".
