OK, here's what I noticed from my COMPARISON
This was the Acer 1.6GHZ Contrino vs the 5670 3.06GHZ HT CPU:
-The Acer with the Ceontrino got over 2 times the battery life
-In doing so, the Acer ran 3XX 3DMAK03 while the Sager ran 9XX 3DMARK03 when on batteries (the Sager ran 3 times higher video performance scores).
-The Acer LCD screen dimmed when on battery while the Sager didn't.
-The Acer had a 4400mah battery while the Sager had a 4000mah battery.
Of course a 1.6GHZ CPU will get more batt life compared to a 3.06GHZ CPU
Of course you will get more battery life from a 4400mah battery than a 4000mah battery
Of course you will get more battery life when you dim the screen than to not dim it when on batteries.
Of course you will get more battery life if you throttle down the GPU (video card/ATI/PowerPlay) than if you don't when on batteries.
That's where your battery life comes from... mainly the loss of performance. That is fine for many people who are willing to give that up for more batt life, but to pin it all on it being a Centrino processor is ignoring a lot of what I've seen. Of course it ran as well as most others in video when plugged in, it's the GPU doing this... the M9 has on board prosessing and memory.
I'm not being biased, I think the setup is better for many people, just not for me and many others wanting full performance. Most review sites are not listing all these facts. I'm not saying the Centrino doesn't get more battery life. It's a 1.6GHZ CPU... with that and other things will get it more battery life over a P4, but it's not to the degree people are trying to put it off to you. You can quote review sites all day and say I'm biased because I sell Sager, but where do you think these review sites get paid?!?!? I think the Acer is a solid system which we use daily to really get to know. I think the Centrino has great power and battery life for it's speed. I think it's price is very high and not a bang for the $ in performance by any means. It seems to be getting talked up like that fish my neighbor caught last year. In another week, it will be blowing away the future 4.0GHZ CPU with the 800FSB I'm sure.
Like GamingGal said, the extra cache will give the more performance... but put it up against a 3.06GHZ HT? lol, not anything over a 2.0GHZ P4 from what I've seen. Sager doesn't even sell anything under a 2.4GHZ CPU in the 5670 and 8887. Also, what about the 800FSB coming? Do you think they will ever dare take the Centrino there? You can bite on marketing, after all, companies may many millions of $ to get you to (hi Alineware!)! Intel wants to pay for their R&D =) and I only want the truth. Sager is looking at Centrino and may very well release a model with it in coming months. It may be a great choice for many people, I doubt it will ever be for me personally. That's the truth as I see it and why PCTorque keeps it real and people respect that.
