In search for the perfect laptop for video editing, I have come to have hands on 4 G750 JM units, and just received my first JS unit. Below I will be posting benchmarks ran between the two.
Reasons for the 4 JM units, Unit #1 overheating 100-105c, Unit #2-3 subpar build quality and screen issues, Unit #4 subpar build quality, thermals, and keyboard button issues.
So far JS is 12 hours old. Great keyboard and build quality, just like my first JM. Thermals, TBD.
**NOTE** This is my first (and hopefully last) JS series, so if temps or anything are different than yours, please post. As far as the JM are conserned, I feel that they should be very accurate, since I've did the same on 4 now.
Quick notes between the two.
They are both the same laptop, only thing different is the GPU (and ssd or lack of ssd) Which by the way is sandisk slow crap ssd.
The JS seems to idle warmer than the JM, both GPU and CPU. Cpu upon boot at 4-8% cpu will run 50-55c. Whereas the JM will sit around 40-45c. This is same CPU, not sure why my temps are higher. Overall fan noise on the JS, on average, is about on par with the JM, while the JM is under max load. Both the cpu/gpu fans on the JM only got more than the faintest bit noticeable when I was gaming or stressing. And gaming it wasn't bad, nor stressing. The JS, runs warm, fan noise is noticeable on cpu idle, throw 5 chrome pages and its where the JM was at full stress. Full stress on JS and its loud, when I say loud I don't mean ubnoxious, but it is loud. GPU noise, on JM even when stress or gaming is very quiet/maybe noticeable. GPU on JS, well its definitely noticeable, and can get loud, again loud is not obnoxious.
Now sadly, up to this point, I've only ran Titanfall on both laptops, which isn't a good game to compare laptops on. It limits fps at 60. But I can play high on the JM with all goodies on at 60fps and no problems, turned up to insane on the JS, and it plays like the JM on high. No complaints on either laptop.
*Now for benchmarking/testing, all drivers are the same, windows profiles the same, settings the same, power plans the same*

JS - 46-50c (avg)
Furmark - 1080p, preset 15min burnin
JM - 12FPS, GPU 63c, fan noise very minimal (had to almost put ear to rear fan exhaust to hear it)
JS - 22FPS, GPU 85c, fan noise audible from 5-10ft away (not abnoxious)

JS – Score 101497, Graphics 176001, Physics 40900
Really surprised by the PCMark8 test, the JM actually consistently beat out the JS in icestorm, and the rest of the benchmarks showed little difference between the two. Another big thing is the furmark tests also show very minimal differences between the two chips. Kombuster shows average 10fps gain to be had on the JS.
So, my final thoughts, the JS is definitely not worth the upgrade over the JM. The 860m with Maxwell is a very efficient chip. It benches very close and passes the 870m in some cases, and gaming wise your looking at a 10fps difference. The 860m plays any newer game at high settings without problems, and runs 20c lower than the ‘upgraded’ 870m.
Any thoughts, comments, or personal benchmarks please comment.
*Note* I didn’t save test scores, wrote them on paper. I 100% am providing accurate information in which I received from running the above tests. Not trying to gain anything here so no reason to lie, just trying to help anyone reading.
