I'm not a fan of rebadging GPUs, as you can see here with our AMD Radeon HD 8000M Series news, but it looks like NVIDIA have also pulled out their huge green rubber rebadging stamp, too. Le sigh.
NVIDIA are pushing new parts out to OEMs, with two being unveiled thus far: The GeForce GT 730M and GeForce 710M, there aren't many details on them at all, but AnandTech have used their magic powers to try and figure out what we should expect, as the picture above shows.
The 730M looks like a GK107-like rebadge, which we have now as the 640M, which supports Kepler-based tech such as TXAA, PCIe 3.0 and DisplayPort 1.2. This could end up being a 650M rebadge, but we won't know for a little while yet. The other part listed is the GeForce 710M which should be a GF117 rebadge, and should end up being a rehashed 620M. This chip doesn't support Kepler features such as PCIe 3.0, TXAA or resolutions above 2560x1600.
