Soo, I didn't take any pictures of me building the system, but to be honest, there is nothing special about it. I think you are all more interested in the actual performance of it so here goes.


I've compared it to H2O-Micro which has a Core i5-4670 4T/4C.

Cinebench R15

i5-4670: Multi 496/Single 138/Ratio 3.59x

i7-4785T: Multi 519/Single 107/Ratio 4.86x


As you can see the 4785T outperforms in terms of multi-threaded even-though is was only running at 2.8Ghz vs. 3.6Ghz, this is due to HT support on the i7. so if you are working with heavily threaded content the i7-4785T is a nice alternative to the i5-4670 considering the extremely low power consumption, though at a higher price.


Single threaded performance is a different story, here the i5-4670 outperforms by about 30% due to its much higher speed. but the i7-4785T still manages to put down a nice performance.


One of the downsides of the i7-4785T is the low TJmax 72C vs 100C on the i5-4670 that is allowed, this means that it tends to throttle a lot earlier, I've only had it happen once because I was putting a 100% load on the CPU for a couple of hours.


It terms of power consumption the entire system idles at 18W, during movie playback it goes up to 21W and when a full load is applied it can go towards 45W.


If anyone has a request for another test please let me know.
