Introducing the NVIDIA GeForce 700M Family

With spring now well under way and the pending launch of Intel’s Haswell chips, OEMs always like to have “new” parts across the board, and so once more we’re getting a new series of chips from NVIDIA, the 700M parts. We’ve already seen a few laptops shipping with the 710M and GT 730M; today NVIDIA is filling out the rest of 700M family. Last year saw NVIDIA’s very successful launch of mobile Kepler; since that time, the number of laptops shipping with NVIDIA dGPUs compared to AMD dGPUs appears to have shifted even more in NVIDIA’s favor.

Not surprisingly, with TSMC still on 28nm NVIDIA isn’t launching a new architecture, but they’ll be tweaking Kepler to keep it going through 2013. Today's launch of the various 700M GPUs is thus very similar to what we saw with the 500M launch: everything in general gets a bit faster than the previous generation. To improve Kepler NVIDIA is taking the existing architecture and making a few moderate tweaks, improving their drivers (which will also apply to existing GPUs), and as usual they’re continuing to proclaim the advantages of Optimus Technology.

Starting on the software side of things, we don’t really have anything new to add on the Optimus front, other than to say that in our experience it continues to work well on Windows platforms—Linux users may feel otherwise, naturally. On the bright side, things like the Bumblebee Project appear to be helping the situation, so now it's at least possible to utilize the dGPU and iGPU under Linux. As far as OEMs go, Optimus has now matured to the point where I can't immediately come up with any new laptop that has an NVIDIA GPU and doesn't support Optimus; we're now at the point where an NVIDIA equipped laptop inherently implies Optimus support.

The second software aspect is NVIDIA’s GeForce Experience software, which allows for automatic game configuration based on your hardware. You can see the full slide deck in the gallery at the end with a few additional details, but GeForce Experience is a new software tool that’s designed to automatically adjust supported games to the “best quality for your hardware” setting. This may not seem like a big deal for enthusiasts, but for your average Joe that doesn’t know what all the technical names mean (e.g. antialiasing, anisotropic filtering, specular highlighting, etc.) it’s a step towards making PCs more gamer friendly—more like a console experience, only with faster hardware. ;-) GeForce Experience is already in open beta, with over 1.5 million downloads and counting, so it’s definitely something people are using.

Finally, NVIDIA has added GPU Boost 2.0 to the 700M family. This is basically the same as what’s found in GeForce Titan, though with some tuning specific to mobile platforms as opposed to desktops. We’re told GPU Boost 2.0 is the same core hardware as GPU Boost 1.0, with software refinements allowing for more fine-grained control of the clocks. Ryan has already covered GPU Boost 2.0 extensively, so we won’t spend much more time on it other than to say that over a range of titles, NVIDIA is getting a 10-15% performance improvement relative to GPU Boost 1.0.

Moving to the hardware elements, hardware change only applies to one of the chips. GK104 will continue as the highest performing option in the GTX 675MX and GTX 680M (as well as the GTX 680MX in the iMac 27), and GK106 will likewise continue in the GTX 670MX (though it appears some 670MX chips also use GK104). In fact, for now NVIDIA isn’t announcing any new high-end mobile GPUs, so the GTX 600M parts will continue to fill that niche. The changes come for everything in the GT family, with some of the chips apparently continuing to use GK107 while a couple options will utilize a new GK208 part.

While NVIDIA won’t confirm which parts use GK208, the latest drivers do refer to that part number so we know it exists. GK208 looks to be largely the same as GK107, and we’re not sure if there are any real differences other than the fact that GK208 will be available as a 64-bit part. Given the similarity in appearance, it may serve as a 128-bit part as well. Basically, GK107 was never available in a 64-bit configuration, and GK208 remedies that (which actually makes it a lower end chip relative to GK107).

    Haven't you heard? Windows 8's desktop is apparently unusable, you are forced into the Start screen for everything. And, it's really, really hard to click the tiles with a mouse.

    Obviously I'm referring more the the OEM feelings than what people really need; I probably should have put requires in quotes. :-) But, I will say that I find the Start Screen to be much more useful with a touchscreen vs. a mouse. I will also say that I'm still running Windows 7 on all my personal use laptops and desktops, and on most Windows 8 laptops I install Classic Shell.

    I wonder why Vizio chose to go with AMD for their dGPU's, putting the 8670M in their new 15.6" thin and light
  • JarredWalton - Monday, April 1, 2013 - link

    Almost certainly thanks to pricing, but don't forget to note that the 8670M is only in the AMD A10 based model -- oddly, at least right now, the Intel model doesn't support a dGPU?
  • lightsout565 - Monday, April 1, 2013 - link

    Exactly. Samsung's new Series 7 Chronos offers a quad core i7 (identical to the Vizio's) with an 8870m. Look's nice.

    My 670mx in my g75vx is a gk104 will that make any difference in overclocking or does the memory width hold it back?
  • karbom - Tuesday, April 2, 2013 - link

    does it mean that gt 730m which appeared earlier this year in laptops such as dell inspiron 14r still uses GK107(128 bit memory bandwith) rather than just announced 64 bit GK208.
  • JarredWalton - Wednesday, April 3, 2013 - link

    I think so... but you'd have to see if it's a 64-bit or 128-bit interface. To my knowledge, only GK208 supports 64-bit interface configurations. (Well, along with Fermi of course.)
  • karbom - Saturday, April 13, 2013 - link

    Thnx i guess i have no other option than to 1st buy inspiron 14 and then check it out myself for 128/64 bit interface LOL........!

    Well played, nVidia!

    Nobody bothers any more to complain about Fermis still being used in the "700 series", let alone the same Kepler chips as in the "600 series". Maybe they should start to simply attach years to the model numbers, to make it clear that they say nothing anymore about the technological generation or capabilities of the chips.
