Can someone explain what turbo mode in the Intel i7 is about?

by on February 6, 2010

Q: I need help with the Intel i7 Processor series. I want to purchase a gaming PC but I have been everywhere and cant find any information on which model is the best at running top notch games in terms I can understand.

I already know I cannot afford the latest model i7 920XM 2.0GHz 3.2GHz Turbo Mode, 8MB Cache but I was looking at the i7 620M 2.66 GHz 3.33GHz Turbo Mode, 4MB Cache, i7 720QM 1.6GHz 2.8 GHz Turbo Mode, 6MB Cache, and i7 820QM 1.73GHz 3.06GHz Turbo Mode, 8MB Cache.

All this Turbo mode stuff has got me really confused. I was always told a higher GHz processor was better at running games but the higher price processor models have lower GHz and higher turbo mode GHz. Does that base GHz matter since it can kick into turbo mode? And what’s the cache part of this? Do I want a big cache for running top notch games or is that trivial?

I desperately need this explained to me or even a link with simple ratings on the processors that I can understand. Everything I have found by yahoo and google searching is in super geek form that I cannot understand.

    Save your money and buy yourself an Intel i5-750. Put the money you saved into a better video card (like a Radeon HD 5850)

    Don’t get hung up the numbers, Ghz isn’t a clear indicator of performance, nor is anything else on the spec sheets.

    The best way to compare performance is to use the charts at Tom’s Hardware: http://www.tomshardware.com/charts/

    check out their processor and video card charts to see how different video cards and processors compare to one another.
