2013 shall henceforth be known as the year of confusing mobile GPU branding. We've already been treated to 8000M-series Radeons based on last year's GCN architecture. Earlier today, Nvidia reminded everyone that its GeForce 700M series is also based on a year-old architecture, Kepler, by expanding the lineup with five new models.
Behold! Here are the GeForce GT 750M, GT 745M, GT 740M, GT 735M, and GT 720M, outlined in as much detail as Nvidia is offering publicly right now:
|GeForce GT 750M||384||967 "+ Boost"||128-bit||5000||2GB DDR3/GDDR5||6.3x|
|GeForce GT 745M||384||837 "+ Boost"||128-bit||5000||2GB DDR3/GDDR5||5.8x|
|GeForce GT 740M||384||980 "+ Boost"||128-bit||5000||2GB DDR3/GDDR5||5.3x|
|GeForce GT 735M||384||889 "+ Boost"||64-bit||2000||2GB DDR3||4.8x|
|GeForce GT 730M||384||719 "+ Boost"||64-bit||2000||2GB DDR3||4.8x|
|GeForce GT 720M||96||938 "w/ boost"||64-bit||2000||2GB DDR3||3.3x|
|GeForce 710M||96||800 "w/ boost"||64-bit||1800||2GB DDR3||3.0x|
I should point out a few things about the numbers above. First, the core and memory clock speeds, memory interface widths, and memory configurations are best-case scenarios. Nvidia's partners are free to twiddle with those attributes in order to accommodate their target thermal envelopes. You may also notice the "performance index" figure for each part. That index is computed by Nvidia and is supposed to represent performance relative to Intel's HD 4000 integrated graphics, like so:
Another thing: the official spec sheet says "+ Boost" next to the clock speeds of the GT 730M through the 750M, but it says "w/ boost" next to the clock speeds of the 710M and GT 720M. That wording suggests the second set of speeds includes the GPU Boost peak, while the first set does not. All Nvidia would tell us is, "The 710M and 720M have the same base clock, but [the] 720M can boost to faster frequencies."
Anyway, all members of the GeForce 700M series are Kepler-based offerings fabbed using TSMC's 28-nm process. They all feature Nvidia's GPU Boost 2.0 technology—just like the GeForce GTX Titan—and support for Optimus switchable graphics. Also, as Nvidia eagerly points out in its press release, users can rely on the firm's GeForce Experience tool to determine the optimal graphics settings for supported games. All except the GT 720M and 710M include 3D TV Play and 3D Vision capabilities, as well.
Expect to find the GeForce GT 720M and GT 740M in the wild soon. Nvidia says notebooks based on them are due to ship "immediately." As for the rest of the newcomers, those aren't slated to come out until Intel releases its Haswell processors later this year.
