QX9300 vs 920/940XM

The QX9300 has a stock clock of 2.53 Ghz and can be overclocked till 3.0 ghz. In the i7s, they have stock clock of 2.13 Ghz and those turbo boost stuff on dual or single cores. So, if there is a game which utilizes all quad core then it is limited to 2.13 where as QX9300 can go upto 3.0 ghz. So, is QX9300 better in quad core than these i7s?

 

The Extreme edition processors in the M17X R2 clock boost to 3.2/3.4ghz when all 4 cores are active, and they still manage 3.6-4ghz overclocks. You also have the HT cores to consider, so overall they're much better mutli-tasking processors.

 

Yeah, the EE i7's are definitely faster HOWEVER the QX9300 is DEFINITELY no slouch! Running at 3ghz per core overclocked is faster than any Core2Quad desktop processor and can easy chew and spit out any game or software...so sure its not as fast as a i7, but its fast enough for anything you have to run.

 

Not quite but nearly My desktop Q9650 is 3ghz at stock.

But yeah the 920 and 940 will blow away any and all core 2 quads. The QX9300 at 3ghz or Q9650 probably perform on par with the 820qm at best. However even that processor will excel in certain tasks due to having 4 virtual cores and having faster and more bandwidth and better architecture.

As said though the QX9300 ain't no slouch and will perform perfectly quickly enough even for enthusiasts for a number or years especially if you use throttlestop and push it to 3.3-3.5ghz

 

Are there any benchmarks on these?

 

i've heard of QX9300 running at 4GHz easily and doing stuff.. but really , even a QX9300 is great..

 

scook9 is the only one that I know of that has done that, and that was only in a box freezer with a 20" box fan on top of a cyro LX for benchmark runs..

 

It is not just about raw clock speed, it is also about architecture and efficiency in favor of the i7's.

 

Seconded that. My 940XM @ 3.5GHz performs just as well as a QX9300 @ 4.0Ghz.

 

I would think you would need an extreme i7 to keep up with your QX9300 at 3.0GHz+.

 

Not necessarily, it entirely depends on how threaded and resource heavy the program is.

 

Dell Uk has been offering 940 XM in the M17X( The Dell Online Store: Build Your System. What's up with the US one?

 

the US site never gets updated before other countries do.

 

lol i thought it was the opposite .. must be weird because usually for other companies their US site is updated first.
