[QUOTE="Dave_W, post: 249560, member: 9521"] I've narrowed my laptop search down to two different models and it's brought up a question that only full blown computer geeks would know or even care about. Both laptops are the same with regards to size (17.3" full HD), GPU and 16 GB memory but come with very different CPU's. Laptop #1 - Core i7 4500U, 4M cache, 1.8 Ghz, dual core with a max TDP of 15 W vs. Laptop #2 - Core i7 4700MQ, 6M cache, 3.4 Ghz, quad core with a max TDP of 47 W Clearly the 4700MQ is a more powerful CPU but it also comes with a heavy power burden as well as a potential heat issues while the 4500U is a ULV and designed to use much less power and produce less heat. Another difference is that the 450U maxes out at 16 GB memory, whereas the 4700MQ can accept 32 GB. If this were a desktop that would be enough of a reason to go with the 4700MQ but I can't see needing more than 16 GB on a laptop (unless my desktop goes down and the laptop is all I have). But on the other hand, a CPU like the 4500U draws 1/4 of the wattage will also increase the battery life considerably (hence the reason they're so popular with the ultra-lights). So my question is this - is there enough of a difference between these two chips that a human could possibly notice it in real time? Given that both computers are using the same GPU (GT 750M 2GB GDDR5) would that do most of the heavy lifting when dealing with large image files so the CPU's clock speeds and 2 vs 4 cores not make much of a difference? And given that both are powering a full HD 17.3" screen, is that enough of a reason to go with the 4700 over the 4500? Or on the other hand, am I once again picking fly dung out of pepper and letting my OCD tendencies run amuck? ;) Because I'm known to do that now and then... [/QUOTE]
