330m underclocked in mbp?

[semiotic]

In anandtechs's review of the i5 2.4 ghz mbp, I noticed that the 330m is seriously underclocked compared to the standard values on notebookcheck:

clock 575 mhz, memory 1066 mhz, shader 1265 mhz standard guideline
vs
clock 500 mhz, memory 790 mhz, shader 1100 mhz in the low-end 15 inch mbp.

looks pretty dramatic. could someone with a 15 inch high end or a 17 inch mbp have a look if the 512 memory 330ms are clocked differently?

1) The Sony Z's 330M is clocked at 475mhz, so 25mhz slower.
2) You can overclock it in windows using many different tools. Though I wouldn't recommend overdoing it and watching your CPU&GPU temperatures. Maybe only do this while using a stand so that cooling is more efficient.

I would also be interested to know if the higher-end 15" and 17" are clocked higher, though I doubt it.

Apple has a long and illustrious history of underclocking their GPUs. So if I were to hazard a guess, I'd say they are in fact under clocking the puppy.

the 1066Mhz memory clock seen in the notebookcheck spec sheet refers to DDR3 RAM. The spec for GDDR3 used in the MBPs is 800Mhz, so it's only a 10Mhz underclock, or ~3%. The shader and core are both underclocked by about ~13%

Rivatuner can fix that in a jiffy.

Yes, to save battery life.
