i7 2670qm (quad mobile) vs Q6600 desktop?

[tommo123]

i'm buying a new laptop with the above cpu (8GB etc also). my older PC (other is an AMD x6) has a Q6600 in it.

how do these compare? i assume that even though it's a mobile chip, it will run rings around the older intel? i ask as i'm thinking of getting rid of the older pc and basically using it as a desktop replacement so save some space (has hdmi etc, the keyb/mouse are both wireless and other hard drives can be attached via usb).

what speed is your Q6600 at? at stock it will probably be slower, but some of them could OC pretty well. Also, what graphics cards/other specs do the systems have? All should be taken into consideration.

 

[tommo123]

stock. overclocked to begin with but running at stock due to bsods a while back and never bothered to try again.

for gaming, (it has a 5770) i use my other PC (the AMD one) with a 6950 (bios mod). the laptop comes with a 555m but would only be used for gaming on holidays etc.

the PC i'm looking to replace is used for minimal web browsing (other pc is connected to a 30" dell), video encoding and downloading.

at stock the 2670QM is going to thump a Q6600. Even OC'd it will.

Cinebench for example, a 2670QM is on par with a i7 960 at stock

My 2630QM is close to a 2500k at stock level.

Pretty impressive for Notebooks....

 

[aaksheytalwar]

a stock lappy core i7 will beat any Q9xxx at any speed in terms of real world performance in games and stuff, in terms of smoothness etc, in anything for that matter.

 

[tommo123]

coolio. hopefully could sell bits of the PC and reduce the cost of the laptop that way

At the same speed a 1st generation Intel® Core™ i7 would outperform a Intel Core 2 Duo by 15% to 20%. A 2nd generation Intel Core i7 would outperform a 1st generation Intel Core i7 by 10% to 15%. So with everything else being equal you should get right around 30% better performance with a 2nd generation Intel Core i7 over an Intel Core 2 Quad. The Intel Core 2 Quad Q6600 runs at 2.4GHz. Now the Intel Core i7-2670QM only runs at 2.2GHz but does have Turbo boost up that can raise the speed up to 3.1GHz. While the Turbo boost won't always have the speed up to 3.1GHz it always give some type of speed boost. So it should be safe to say even at it worst the Intel Core i7-2670QM is 30% faster then the Intel Core 2 Quad Q6600.

 

[aaksheytalwar]

It is far more. A 2nd generation outperforms a first gen by 15-25% and then a first gen i7 outpaces a second gen c2 by prolly 20-30% which displaces a first gen c2 by like 10% or so. So the minimum improvement he is looking at in every circumstance is 30-50% and on average greater than 50% and at times nearly double. You can refer to at bench if ou want

 

[tommo123]

are you taking into consideration that it's a mobile part? i assume it's not as fast as a desktop i7

anyhoo, thanks guys

 

[aaksheytalwar]

Even then expect a 30-50%+ performance increase on an average if not more

 

[jacktesterson]

anyhoo, thanks guys

Yep... We are.

The Sandy Bridge I7 Quad Mobiles are almost as fast as there desktop partners.

That 2670QM is going to beat a Q6600 Desktop CPU all over the place, even if O/C'd

 

[tommo123]

cool.

i have an SSD in that PC so i'll probably throw that in the laptop (only 60GB but still). my ps3 drive as a 2ndry. should be nice and snappy then

Based on IntelEnthusiast's post, the 2nd generation i7 is roughly 30% higher IPC than a Core 2 Quad. Take stock speed of the i7 2670 which is 2.2GHz and multiply by 1.3. You get 2.86GHz so the i7 2670 is roughly equivalent to a 2.86GHz Core 2 Quad. B3 Q6600's IME generally hit ~3.2GHz without too much effort, G0 should hit 3.6+, meaning a Q6600 @ 3.6GHz is roughly 25 % faster than the i7 2670 if you are ignoring Turbo boost.

If you are not oc'ing the q6600 then yeah the i7 2670 will be faster.

The maximum 3/4 core Turbo on the 2670QM is 600MHz higher than the base clock. The minimum guaranteed frequency gain is around 300MHz though. At 2.5GHz with minimum Turbo with 30% perf/clk advantage, it would be equal to a 3.3GHz Core 2 Quad.

However, the 30% advantage is only an average. In multi-threaded applications, the combination of Hyperthreading and architectural gains allow Sandy Bridge to have 50-70% gains over Penryn.

id still prefer q6600 over an i7 mobile chip,i already tried a lot of them and what i noticed is that even a c2q chip is faster,it may just be me but i think those should just be labeled as i5.

Well, different hard drives can easily make one "feel" faster than other. But there's a reason why computation results are favored over subjective ones.

 

[HexiumVII]

All things being equal, i think you'd be surprised how much faster the i7s are (regardless of gen) compared to the Core 2 series. Stick an SSD in there and you might not want to use your deskop lol.

 

[tommo123]

that is the plan

--

ordered now. i7, 8GB ram and a 120GB intel SSD (sata 3).

should do nicely for a good while

What about SuperPi test in both CPU? For instance, my msi gt780DXR-446US comes with a i7-2670QM, 16GB DDR3-1333, Nvidia GTX 570M 3GB GDDR5 slightly overclocked by using Afterburner, 2x WD Scorpio black 750GB 7200RPM in RAID 0, Win7 Home Premium 64bits. With turbo boost (P1) on, Intel monitor indicates values between 2.9-3.1MHz, and my max. SuperPi has been 12.230s. I don't know if the Q6600 can get this value.

Super Pi is heavily dependent on clock speeds. My OC'd i3 can do one million in less than 10 seconds. The 2820QM will never be able to compete with that even though it is technically a much stronger CPU.

But, a single threaded, clock speed dependent benchmark isn't really a good indicator of overall system performance. For 90% of my system use, the i7 feels far faster.

I probably need to benchmark the 2 but I feel my QX6700 (OCed to 3.2ghz) is faster than my i7-2630QM. Definitely not limited by hardware since both system has speedy SSD and the mobile has the SATA 3 advantage.

 

[alex_123_fra]

Not a direct comparison but my i7 - 2860QM is about 50% faster as stock than my overclocked Q6700 @3.6 GHz. Mainly used wprime and throttlestop benchmarks.

 

[Makaveli]

This is a very interesting question and thread. Can maybe one of you guys with one of those mobile i7 post some benchmarks numbers then maybe someone with a overclocked Q6600.

I had a friend ask me something similar two weeks ago.

Jeeze guys, just remember you're on the Anandtech forums.

Anandtech Bench says:

Cinebench R10 Multi-Threaded - Score in CBMarks - Higher is Better
(Desktop) Intel Core 2 Quad Q6600 - 9681
(Desktop) Intel Core i7 2600k - 22875
(Mobile - Dell XPS 15 L502x) Intel Core i7 2630QM - 17280

A 2670QM is the same as a 2630QM, except it runs at 2.2/3.1 GHz instead of 2.0/2.9 GHz.

In other words, the 2670QM will f-ing decimate the Q6600.

I've stated this like 4 times in this thread, from experiences with both. Kind of puzzled why people think the Q6600 is faster.

My mobile i7 is as fast as my stock 2500 i5. No way a Q6600 is going to catch a i5 2500, even o/c'd to the max.

O/C that Q6600 to 4.0 if you can, it won't beat a i7 mobile sandy.
