Joni_78 Posted December 12, 2013 Share Posted December 12, 2013 Is there much difference in i7-3520M and i7-3610QM? 3520M is really cheap and i'm wondering if it's worth getting 3610QM. Link to comment Share on other sites More sharing options...
night_stalker_z Posted December 12, 2013 Share Posted December 12, 2013 The i7 processors ending in QM are the only quad core processors for laptops from Intel so it depends on whether you need quad core or dual core. Link to comment Share on other sites More sharing options...

+Mirumir Subscriber¹ Posted December 12, 2013 Subscriber¹ Share Posted December 12, 2013 Is there much difference in i7-3520M and i7-3610QM? 3520M is really cheap and i'm wondering if it's worth getting 3610QM. i7-3610QM packs more cache inside: 1024KB L2 and 6MB L3 vs 512KB L2 and 4MB L3 (i7-3520M) Despite having a lower clockrate, i7-3610QM performs better as it proccesses more data per cycle. i'm wondering if it's worth getting 3610QM. This depends on what you need it for, what your future upgrade plans are, and...money. Elliot B. 1 Share Link to comment Share on other sites More sharing options...
snaphat (Myles Landwehr) Member Posted December 12, 2013 Member Share Posted December 12, 2013 Despite having a lower clockrate, i7-3610QM performs better as it proccesses more data per cycle. What do you mean by more data and performs better? In general, the i7-3520M has better single thread performance. Basically, the i7-3610QM is sacrificing its single thread performance for more cores. There is a trade-off here because it means on one hand you have 4 cores to execute things but on the other hand you have the worse single thread performance. At the end of the day, whats more useful for the workloads he'll be running? Link to comment Share on other sites More sharing options...
Wakers Posted December 12, 2013 Share Posted December 12, 2013 You're aware that replacing a CPU in a laptop is not easy, yes? You'll need to completely dismantle it and may even need an entirely new mainboard with the CPU pre-installed, depending on the model. Link to comment Share on other sites More sharing options...

Thanks, I guess it's 3610QM then allthough it is 45W and 3520M is 35W. Link to comment Share on other sites More sharing options...

What exactly are you going to be doing with the machine? That should dictate what you get. If it is non-computation intensive tasks (web browsing, document creation, etc) , don't go for the quad core. Link to comment Share on other sites More sharing options...

I'm not really sure if quad core has any benefits in Visual Studio? Link to comment Share on other sites More sharing options...

I'm not really sure if quad core has any benefits in Visual Studio? Someone correct me if I am wrong, but I don't think VS can do parallel builds. I have done parallel builds with cmake/make in Linux and they can be considerably faster on very large compilations (on something that can take ~15-30 minutes on a single core). It's also worth nothing that the better single core performance on the 3520 may be better in this case for you. I wouldn't get the quad if I were you based on what you've said. I think it'd be mostly a waste of money for little benefit. Link to comment Share on other sites More sharing options...
