It Really seems like doubling the Shaders more than makes up for the ridiculous overclock on the 660m. I will also note that the y580 hovered around 80 Degress Celsius while the Alienware 14 was at an astounding 67 Degrees Celsius!!!!

I was extremely impressed by how much I could get out of the 660m, but in the long run the 765m was only using a small OC, I'm sure I could push it a little more but I'll save that for future tests

To put things in perspective it's a 20% difference which can mean 25 fps vs 20 fps, 30 fps vs 24 fps, 60 fps vs 48 fps the 765m and 660m respectively.

Games with heavier shaders we will prob see the 765m shine even more This was a synthetic benchmark but I got around 25% more using the 765m stock on Splinter cell Blacklist, so we'll see these results vary.

CS go I got nearly DOUBLE the frames and even less drops in frame in aztec (with AA enabled while the 660m I disabled AA in order to stop the big drops (although frames stayed above 60, the drop in frame rate even going from 90 made a 1 second pause which made it annoying in competitive.)

Funny thing is the Bandwidth on the 660m with OC is 86 GB while the 765m is 70 GB, though it plays a very small role from what I've seen.

I would love to hear feed back

 

Thanks for sharing!! The results seem to be on the Alienware side all the way. The cooling system, processor and video card seem to have given quite an advantage. +1 rep.

 

Thank You sir

 

After doing some more testing, the GPU does indeed throttle but it apprently depends on the game played. Assassin's Creed 3 throttles heavily. Frames dip from 100+ to 30s in a matter of seconds. Tabbing between the game and desktop fixes the frames for seconds.

If I hit FN + F5 (I/D GFX) and force the Nvidia GPU only it fixes the throttle but it's very annoying to have to restart your computer everytime you want to play games properly.

I've tried everything else, including Nvidia inspector and forcing Max performance nothing fixed it except forcing Nvidia GPU. This seems to resemble the Alienware m11x R1, where you HAD to switch between Nvidia and intel yourself.

So Alienware 14 users, for max performance switch to your GPU card only

P.S
One thing I will note is that this is possible in the new Alienware 14, I dont think it would work in the old models. I'm not sure what is different in the arch but I think in the old models the Nvidia card is secondary to the intel (so the video is always running through the Intel this one I suppose it runs through both individually, which might be why the battery isn't as good).

 

Thats exactly what I saw in one of the many reviews I saw.

EDIT1:

Ok so one thing I've learned is that there is a difference in arch sandy/ivy vs Haswell. The sandy/ivy the video runs through the intel gpu and then onto the Nvidia, while the Haswell setups the video can run through the Nvidia alone or Intel.

The optimus issues were seeing seems to be revolving around the optimus technology (the framerate loses).

There have been incidents in the past. We'll have to wait and see from Dell and Nvidia on a possible fix in the future. For now it looks like when I'm home I'll be using discrete for gaming.

PLEASE NOTE THAT NOT ALL GAMES ARE AFFECT, but to be safe I'd keep discrete enabled. You will have to redo your graphical settings in games after you switch (for some at least).
