Intel® Core™ i7-820QM Processor ( 45nm, 8MB L3 Cache, 1.73GHz )

Intel® Core™ i7-920XM Processor Extreme Edition ( 45nm, 8MB L3 Cache, 2.0GHz ) [+$555.00]

Is the difference in the 920XM worth $555 Vs the 820QM?
I know nothing about the i7's. Any pros out there?

Depends if you're extreme or not...

I would say no. In fact, I would say fuck no.

Those things have turbo boost, the 820 idles @ 1.73 but it ramps up to over 3ghz when needed...

The biggest difference is that it is overclockable? I don't know that I would even overclock a laptop, even if Intel says it's ok.

The 820 is certainly overclockable, as long as the BIOS allows it. You're right though, overclocking a laptop isn't the most logical thing to do...but it can be done.

The 920 has a faster clock, and maybe a higer multiplier...but I think thats all as far as differences. I could be wrong though.

So not worth $555???? I think I'm going with the 820QM $555 is just too much for too little difference. Thanks for the input Gooch.... and BTW your new sig is great.

Doing!!!!.....Sumbitch thats a laptop? That cost you one of your nuts and a kidney? I think you posted for me a link to them, I'll have to go back and check them out in more detail.

jigabooplz

now im not sure about laptops but as far as desktops are concerned there is a major difference between the extreme editions and non extreme editions...

the amount of data bandwidth the proc can handle at once.

the QPI for standard I7 procs is 4.8GT/s
for the extreme edition it is 6.4GT/s

guess a weird analogy of that would be comparing a 4 banger civic to a big block V8 truck in how fast it can consume fuel! lol

the extreme can handle far more data volume and process it faster at stock speeds than the regular procs can at overclocked speeds.

i'd still only get the regular one though i can't afford to drop a grand on just a proc and the i7 quad core is already a big step up from my dual core e6600 core2duo

Hopefully more like a V6 to a V8 but I get the comparison.

Cost a bit but I'll use it as my mobile recording machine soon. So hopefully it will pay for itself in a short period of time. And I've been just waiting to upgrade my current system for almost a year.
