Intel Core i7 for laptops benchmarked (720QM, 820QM, 920XM)

So the guys at PC Pro are first publishing benchmarks of the Mobile Core i7 processor for laptops.

  • Performance-wise, the results are quite interesting: the mid-range Core i7-820QM (quad-core running at 1.73 GHz stock) is about as fast as the top of the line Core 2 Extreme QX9300, and it seems to cost arount 470 USD less.
  • Battery-wise, it is hard to extract firm conclusions because the power draw measurements were measured for the full system and in laptops with very different configurations (the Core i7 was paired with a GeForce GT 240M while the Core 2 Extreme was paired with a Quadro FX3700M (comparable to a GTX 280M). Anyway, the 6-cell battery (4,800 mAh) of the Core i7 laptop lasted for more than 200 minutes of light use, that’s very good for a high-performance laptop.

Stay tuned for more performance data of the Mobile Core i7 processors.

Found via: Portables4Gamers, Engadget, Fudzilla.

Update: more benchmarks. The advantage of the i7-920XM over the QX9300 is not embarrassing, but considerable. I’m still not convinced by the battery life tests.

Do you know what’s the best Core i7 processor for your next laptop? Have a look at the Core i7 laptops list.
