i7-2630QM versus i7-2620M
Posted: Sat May 28, 2011 3:25 am
After lots of reading online and seeking advice, I have ordered a T520 with a quad-core i7-2630QM and NVidia Quadro NVS 4200M Optimus, along with SSD and 8GB ram. The alternative I was considering, at the same price, was a dual-core i7-2620M with Intel gpu only. Now several people online have suggested that perhaps the quad might not be so good for a quiet business machine! Should I go the other way? My present W500 with 35watt TDP T9400 cpu, ATI Mobility FireGL V5700 and SSD runs mostly silently, which I really like. Maybe I should phone Lenovo and ask if I could change the cpu and the gpu? I want a machine as quiet but better than my W500, and i like the concept of 4 cores, as well as again having the flexibility of switchable gpu's as in my present system. I am depending on both the quad and dual i7's being similarly cool and efficient when doing things like web browsing and office applications, despite the quad having a higher TDP. Would that be so? Or is there a huge difference between the 2 chips even in close-to-idle computing? Perhaps someone could bring some clarity to the two options?
