i7-3612QM vs i7-3720QM

Is there a reason the slower 3612QM costs more than the 3720QM besides lower 35w TDP?

 

Its a much rarer processor that costs us more from Intel so we have to price it accordingly. As Intel isn't making as many of these as say the 3610QM or 3720QM

 

That explains it.

Thanks.

 

To add to mythlogic's answer, as far as I know, the 3612QM is meant for ultrabooks (hence the low wattage), so a cherry-picked cpu that does comparable performance using less energy and dissipating less heat is bound to be more expensive. Kinda of a niche market that you wouldn't need unless very long battery power is a priority (as opposed to a DTR or gaming laptop).

 

are there any benchmarks out there to show the actual performance dif between the 3610 and the 3720? It it worth the 160 upgrade?

 

see notebookcheck for reference, if ure talking about the 45w 3610qm. As far as i remember there was like a 10-15% difference to the 3720qm. As for the 3612qm,havent seen any benches yet....

Just curious why Mythlogic's price on the W110ER is 221 dollars more than XoticPC's price? I see the CPU is different but you get 8 gb at xoticPC and double the harddrive space. As a customer i'm curious

Also how is the battery life with 3612QM next to 3610QM?

 

Battery life? My guess would be within a matter of minutes of each other.

 

The battery life is a little bit better. Also the price difference is because of our extensive building and testing that we do, we don't resell Sager's we hand build and test every one of our machines, and do a lot of engineering on all the different models (Hence all the different and exclusive options we have)

thanks!

 

Will this shipped before may 15th aka diablo day

 

What about heating issues

 

3720QM's are shipping now, 3612QM's will be a little late as we have to fly them across the world (Import them), heating of course they are going to run cooler also.

 

I didn't know you are "that custom" and have even pilots in your team.

 

What they mean is that have to do successfully finish a flight simulator run from China to Michigan in order for Intel to send them chips.

 

Chips, Cola, Crisps and whatnot. Thats bad for our health.

 

So neither the 3612 nor the 3610 chips are good for our health?

I heard at least the 3612 makes our pockets very light and is suppose to be a little cold.
The 3610 on the other hand leaves a little weight in our pockets, but maybe a little hot to the touch.

Very difficult decision...

 

Hi,

Can you please quantify "a little bit better"?

Thanks,
Kev

 

Soon as we get them in we'll be happy to quantify a little better... a little better.

 

They also have a lot of things included with the base model that you have to pay for elsewhere such as screen calibration and IC diamond.

 

I am also interested in the higher priced 35W i7-3612QM versus the 45W i7-3720QM (or i7-3610QM) in regards to battery life, specifically in a Clevo W110ER 11.6".

Looks like the i7-3720QM has a few extra features vs the i7-3612QM. Battery life?

 

i dont think itll make any difference as to battery life. TDP isnt power consumption. that being said, the powersaving frequencies are identical@1200 Mhz, as well, so the way i see it, the 3612QM is only gonna give u a cooler running laptop (which isnt too bad considering how hot the W110ER can get ^^)

cheers

 

And it is not proving to be true as 3612QM seems to be running just as hot as the 45W variant 3610QM.

 

huh! that sucks

indeeeeeeeed ... thought it was a promising chip too

 

Great info, thanks guys. Lots to think about.

A Clevo reseller tells me that the 35W i7-3612QM offers slightly better battery life of between 5%-10% versus the i7-3720QM, and runs cooler allowing it to run at higher clocks for a bit longer.

 

building a laptop and wondering the same thing its 175$ to upgrade from 3612 to the 3720? is it worth it considering speed and low %battery loss? will be pairing with GT650M 1GB thanks

 

depends on your work.. but no not really

I would stick to the 3610QM cheaper and faster

 

thanks for the quick reply i would be using for work and school 8-10hr a day have ac hookup most places and would be playing d2 and d3 some... and i think its a 3610 not the 3612.... ill stick with 3610 thanks for the help

 

This. What you guys forget, is that Intels turbo boost technology (and its throttling technology in general) works around the heat out put of the CPU.

The 3610qm also has a 2.3 ghz clock speed opposed to the 2.1ghz of the 3162.

Anyways, what I believe is happening, is in the end, they both peak around the same temperature. But the CPU boost on the 35w will be greater; the ratio that is. Performance wise, the 3612 is lesser than the 3610 in benchmarks, probably because of the higher clock speed on the 3610.

I have a 45w 2630qm @ 2 ghz and it performs just a tad worse than the 3612. Ive considered getting a laptop with the 3612, especially since mine as no USB 3, If I do I can post temps here or something. Hope I was useful in some way. Cheers.

As far as the 3720qm, It performs MUCH better than the 3612 and probably doesnt kill battery too much more, since all new laptops with Intel CPUs have a basic throttling down technology unrelated to Turbo Boost. My CPU is usually at 800mhz while idling, or doing basic tasks. Such a great power saving tool. Leave it to intel to think up the genious. Id go with the 3720 you wont be dissappointed. It wont be obsolete for a while.

 

The 3610QM and 3612QM both idle at about 0.9V and 1200MHz. There will be little difference in battery life between the two, any difference will likely be due to measurement error. 3 hours battery life is 180 minutes, 5% would be 9 minutes more. The 3612QM is Intel's marketing at is finest. The claim that they have a 35W quad core. It's just a slightly downclocked 3610QM. They are the same chip, just the 3612QM is cherry picked from 3610QM stock, downclocked and slapped with a 35W TDP sticker.

 

Yup, that's what I heard when the 3612QM first came out.

Cherrypicked from the 3610QM bin, those that survived the 35W @ 2.1 was slapped to be the 3612, the rest are the 3610.

But still, it's more than just marketing.. 35W TDP means 35W.. that's more than 20% Wattage reduction, it will translate to battery life if you're stressing the system on battery - when using power saver mode or in idle, yeah, the 3612QM won't do anything.

 

Mythlogic did some extensive testing and temps and power were pretty much same as the 3610QM. 35W just means it fits in 35W TDP envelope or less. The 3610QM could possibly run at 36W TDP but since they only bin at 35W and 45W it would sit in the 45W TDP. So it's not 10W more power used, it's just that it requires a 45W TDP cooling system because it will barely work with a 35W TDP one.

 

Ah, it makes more sense if it's just a threshold thing.

Gotcha...

So I guess the 3612QM doesn't really hold its value against the 3610QM..
