we need them to finish working on 20nm fast. TSMC just can't do it anymore. global foundries has 14nm only on paper too....

I'm actually fairly impressed. Their website says a max of 6 hours battery on "UMA" mode. Would you be able to test this, Tom?

Previously I wouldn't consider getting a gaming laptop due to their short battery life, even when not gaming. But if a laptop with this kind of hardware can manage 5 - 6 hours, I'd consider it...

Page one gives the impression you might include desktop cards so we could get a frame of reference with regard to desktop v laptop GPU performance. Then I looked immediately at the BF4 page and found no desktop GPUs in the performance charts?

Highly disappointed overall by the 800M series performance. I can feel assured that my GTX780Ms in my Alienware 18 will serve me well for at least another year. So, whatever happened to multi-core GPUs?? The concept works well for desktop CPUs, yet we have not seen it in desktop or mobile GPUs as of yet? ATI's Hawaii GPU comes close in certain aspects regarding behavior like a multi-core GPU by handing off processes to other chips within the die. One step closer to a next-gen GPU, yet still so far...

A shame this didn't include the Maxwell-based 860M. It performs much more in line with what we'd expect from a true next-gen mobile chip (I'm currently using said chip, and still exercising its capabilities). I can say it's roughly 30% faster than the previous gen 765M, and benchmarks by others have shown it to be twice as fast as the GTX 660M while staying at a max of 50W TDP. I've yet to do any real benchmarking myself, so if anyone cares to see any, leave me some suggestions of what to use (preferably free software).

Is there any way of knowing if you get kepler 860 or maxwell 860 when you buy a laptop?
I hate these kind of naming tricks... Even 860a and 860b or anything that gives out what you will get.

It is difficult to know unless you get more specific information from the manufacturer before purchase (or find benchmarks of the computer model you're looking at beforehand). The MSi GE60 Apache Pro was the first notebook to feature the Maxwell-based 860M.

Scumbag Nvidia. Want a new GPU? Here's exactly the same piece of silicon with a slightly faster clock rate and increased power usage, and higher price. Laziest business model ever.

We have a couple complete notebooks set aside for that type of review :)

GPU's have been multi-core for several generations. And dual-GPU mobile solutions have come and gone several times as AMD basically applied a dual-GPU name to a pair of notebook modules (in CrossFire).

Yes, the 860M Maxwell is a 2GB card that is soldered directly onto the motherboard with only 640 cuda cores w/ 50W TDP. The Kelper 860M is 4GB and is MXM (replaceable) with 1152 cuda cores w/ 75W TDP.

As an addendum, I was unaware that the Kepler 860M even came in 2GB - but according to Tom's it is?
I was going to comment earlier and ask Thomas about this. Did Origin PC come up with custom 800M-series modules for this article?... or was half the VRAM somehow disabled? If not, I'm confused. The EON17-S as available on their web site comes with the "standard" double-memory configurations - 4 GB for the 860M, 6 GB for the 870M, and a whopping 8 GB for the 880M. I didn't see this mentioned in the article at all. On other forums, users have indicated this "double-VRAM" is a waste. It would have been nice if this article had put the "double-VRAM" to the test, especially at the QHD resolution.

I checked the pictures in the article's image gallery :) GPU-Z shows that the memory amount in the tables was wrong, so I corrected the tables. Thanks! I wish someone would have caught this earlier, but I'm glad I at least got to correct it the same day.

Using a GTX 660M right now, I'm actually quite happy with it... I think some people underestimate what even a 'lowly' mid-level GPU is capable of these days. Can't wait to pick up Sager's refresh of the 9170 with an 870M in it!

Oh, and it's nice to see so many replies in the comments section by the author - keep up the great work. Always interesting!

still waiting on laptop manufacturers to treat laptops like desktops, instead of losing their business while trying to treat them like tablets. there's no reason why laptops shouldn't be fully upgradable with specified form factors for the sizes available.

You can find a comparison between 860m Kepler vs. Maxwell on notebookcheck.net. They claim Maxwell has a 10% advantage in gaming performance, and that Kepler is slightly worse than older Gtx 770m, but far better than Gtx 765m

I'm confused. Can someone help me identify whether or not my chip is Maxwell or Kepler based? I bought the MSI GE60 Apache Pro, and it comes with an 860M graphics card. I've read conflicting comments on whether or not it is Maxwell or Kepler. Looking at GPU-Z, it states the Memory size of my graphics card is 2GB. Does this mean it is Maxwell-based? Thanks
