Pros: Excellent Single/Multithread performance, impressive turbo
Cons: Can run warm, lots of variables to consider for the average consumer
Its a bit of a mouth full if your new to the mobile space, so I will break down that statement as best I can. First off, i7 does NOT automatically denote a quad mobile chip, as there are i7 Dual core variants that have hyperthreading, slightly higher clocks (compared to i5's) and typically a slightly larger cache amount (When compared to i5's). So when in doubt, simply look at the model CPU in the laptop your interested in, and look at the Intel archives for core count and other information, if not already provided by the retailer. Do not rely on the retailer to have that information readily available and/or accurate.
The CPU itself is comparable to many desktop variants, mainly the 3770 as mobile CPU's are near impossible to overclock anymore.
As you can see here, in Cinebench R15, my CPU compares slightly less than that of the 3770 in this synthetic benchmark. Quite impressive for a mobile CPU considering what we used to work with in the Core 2 days.
XTU - 749 marks - Core i7 4700MQ @ 3500MHz
Another benchmark to use as comparison with the built in utility within Intel XTU. This can also be verified via hwbot.
Also ran the trial version of Geekbench (32-bit single and multi thread) for additional comparison.
Additional benchmark for your consideration, I dont have any other hardware at this time to compare it with.
Whats also important to consider, is that this CPU can run pretty hot with a poorly designed heatsink, single heatpipe for CPU/GPU, and/or bad Thermal paste application. So when considering this CPU or that of a higher caliber make sure you can apply thermal paste without voiding warranty, that the cooling solution has dedicated heatpipes, as well as wait for reviews to see how each model cooling solution operates at idle and load to determine what your ok with.
Also, This CPU has no problem with fully utilizing both my 755M's in single or SLI, stock and overclock. Which is the equivalent to a 770m or 7970m. There will be no hardware level bottleneck from CPU > GPU
Any additional comments or questions regarding benchmarks relative to this CPU, let me know and I will do the best I can to accommodate them into the review.
