NVIDIA GeForce GTX 860M Detailed
NVIDIA slipped out the first mobile GPU based on its GM107 silicon, the GeForce GTX 860M, which was spotted on the forumscape. The GTX 860M is configured identically to the desktop GTX 750 Ti, featuring the chip's full complement of 640 CUDA cores, 40 TMUs, 16 ROPs, and a 128-bit wide GDDR5 memory interface, holding 2 GB of memory. The core is clocked at 540 MHz, and the memory at 5.00 GHz (GDDR5 effective).
The mobile MXM card was put through a battery of synthetic tests, in which it was found to be twice as fast as its predecessor, the GTX 660M. In 3DMark 11 (performance preset), it scored P5339, compared to the P2563 points scored by the GTX 660M. In 3DMark 11 (extreme preset), the story is similar, with the GTX 860M scoring X1662, compared to the X774 scored by the GTX 660M.

Great performance, though.
HD 7970M
GTX 780M
FWIW: I wasn't making any comparison. I just provided a couple of links to the SKUs another poster asked about.
@Ali bakhshi: 880m ? I previously heard of them but they were Kepler-based, is nVidia releasing Maxwell-based 880m as well?
Seems pretty ok I think
can i solder it to a 2 year old all-in-one pc and expect it to work?
You don't want to accidentally kill your PC, so I'd suggest a practice run first to get acquainted with the methodology¹:
1. Buy a R9 290X, lever the GPU out with a butter knife.
2. Find a cheap HD 2900XT (PRO TIP: the R600 is pretty close to the Hawaii die in size). Use the butter knife again. If the bond is really stubborn, loosen carefully with an oxy-acetylene gas axe.
3. After checking the BGA pinout map for both the R600 and the 290X's socket, solder lengths of bog-standard copper wire to the R600 pins and solder randomly to the socket pinouts. Leave the GPU loose on the PCB for the homemade look, or hot glue it to the socket for the PRO look.
4. If the *NEW* 290X fails to work, change the wires around until it does.
¹ Modding carries with it an inherent risk. Proceed at your own risk...but knowing your skill level, I'm sure you'll handle it just fine
The 860M is a successor to the 760/765m and should offer around 10-15% more performance in otherwise identical laptop setups. Roughly speaking you will be looking at 750TI -10-15% in real world terms.
The 880m looks like it will be a 780M refresh - higher clocks but same TDP limit (thus similar performance real world).
If a new architecture can be twice as efficient at the same performance level, it can also be made to run twice as fast at the same TDP.
Maxwell is looking more and more awesome with each new release.
I personally, am holding out until the 20nm chips come out so that I can upgrade my gaming laptop. I am going NVIDIA this turn, I am kinda sick of AMD and their problems. I am going for a 970m or what ever it will be called, the 2nd from the top in SLI.
