I have a stock G73JH - it's a generation 1 i7-720QM Clarksfield (1333mhz ram, USB 2.0, Sata II, among other slower bus speeds and overall performance).

And I'm looking at upgrading to say a stock G75 which is generation 3 i7 Ivy Bridge. And I wonder - just stock for stock (no SSD or other HW enhancements) - OH too, and not regarding GPU speeds - just pure overall computer performance for everyday / constant usage - would I see a huge improvement coming from the G73JH?

I was going to just get a new current generation SSD for my G73JH (SATA III ssd - even though the G73JH is SATA II the current generation drives will saturate the SATA II port much better than the older SATA II SSD drives). I think the new SSD would greatly enhance my current G73JH over stock. And I could of course do the same with the G75 - so wonder just stock for stock (ie Clarsfield vs Ivy Bridge) if it's worth upgrading my G73 at this time or waiting another year or so for the next gen Intel cpus.

Oh yeah it is. That 720 is pretty slow and ivy bridge even without turbo will span it take less power and run cooler. Factor in turbo and that i7 720 shows its age.

Thank you bignazpwns - from what I can gather an i7 Clarksfield to i7 Sandy Bridge yields about a 40-50% increase in performance. And i7 Sandy to i7 Ivy yields about a 10% increase in performance.

So I assume that i7 Clarksfield to i7 Ivy Bridge would be at least twice as fast. Does anyone know if this is a safe bet to make?

so what do you want? change GPU on G73 or ?

Has no choice he wants to go ivy he has to get a new pc. Even the 840 qm is slower then the 3630qm.

Twice as fast, probably not, but it could be close to that, depending on which particular chips you are comparing in each case. If you take the lowest end Clarksfield (720QM) versus the lowest Ivy (3610QM) the difference is probably an increase of 75%.

Here ya go.

i7 740qm

3DMark 06 3334
super pi 1m 14.6
Sandra Dhrystone 47420
Sandra Whetstone 40900
Cinebench R10: Rendering Single 64Bit 3878.1
Cinebench R10: Rendering Multiple CPUs 64Bit 10893.6

i7 3610qm

3DMark 06 5970
super pi 1m 11.7
Sandra Dhrystone 113444
Sandra Whetstone 76639
Cinebench R10: Rendering Single 64Bit 5609.8
Cinebench R10: Rendering Multiple CPUs 64Bit 20823.3


And just for S's and G's here is the i7 920XM

3DMark 06 3815.8
super pi 1m 13
Sandra Dhrystone 48000
Sandra Whetstone 43210
Cinebench R10: Rendering Single 64Bit 4258.5
Cinebench R10: Rendering Multiple CPUs 64Bit 13312.5


As you can see the lowest end ivy bridge i7 beats the best Clarksfield like it did not have dinner made when it got home.


And just for S's And G's current prices.

i7 740QM $89

i7 3610qm $190

i7 920XM $500


So for value you slap a i7 920XM in and even with the unlocked multi use intel xtu to oc it at beast your barley going to keep up with a stock i7 3610qm assuming you can cool it. And then you are still stuck with a slow cpu and a pretty old chipset. As where for $800 more you can just pick up a G75VX with a i7 3630QM GTX 670MX and a newer chipset that supports better features. No real sence in not upgrading really. I mean at the best case you can save some cash and upgrade to a hd 7970m but even then your talking that and the cpu upgrade to a 920xm just to keep up you will save maybe $300 at most just to keep up and even then that GPU will be bottleneck really bad by the HD 7970m. And then you dont have to go through the process of taking a sager/clev. hd 7980m flashing the bios and disabling endro.


My advice. Sell the G73. I seen therm go on craigslist for about $600 to $800 depending on if its in good condition and if you can find a guy whos all in awe at the rog sticker and never seen another brand other then a alienware. $800 gets you $500 away from a new G75VX that will crush you G73.




But yeah in some stuff it is twice as fast and others its not that fast. Really all dapends on what you are doing. But it is a worthy upgrade and if you match it with a GTX 670MX it is a nice combo.
