NVIDIA has announced new GPUs to round out their 900-series mobile lineup, and the new GTX 960M and GTX 950M are based on the same GM107 core as the previous 860M/850M parts.
Both GPUs feature 640 CUDA Cores and are separated by Base clock speed, with the GTX 960M operating at 1096 MHz and GTX 950M at 914 MHz. Both have unlisted maximum Boost frequencies that will likely vary based on thermal constraints. The memory interface is the other differentiator between the GPUs, with the GTX 960M sporting dedicated GDDR5 memory, and the GTX 950M can be implemented with either DDR3 or GDDR5 memory. Both GTX 960M and 950M use the same 128-bit memory interface and support up to 4GB of memory.
As reported by multiple sources the core powering the 960M/950M is a GM107 Maxwell GPU, which means that we are essentially talking about rebadged 860M/850M products, though the unlisted Boost frequencies could potentially be higher with these parts with improved silicon on a mature 28nm process. In contrast the previously announced GTX 965M is based on a cut down Maxwell GM204 GPU, with its 1024 CUDA Cores representing half of the GPU core introduced with the GTX 980.
New notebooks featuring the GTX 960M have already been announced by NVIDIA's partners, so we will soon see if there is any performance improvement to these refreshed GM107 parts.

Fremont, CA (June 26, 2014) - ASUS Republic of Gamers (ROG) today announces the G550JK gaming notebook, a compact powerhouse with acrisp 15.6-inch display that offers all the benefits associated with the award-winning ROG notebook range in an even more portable form factor. Powered by the latest 4th-generation Intel Core i7 processors, and featuring an NVIDIA GeForce GTX 850M GPU that can be overclocked thanks to ASUS TurboMaster technology, the G550JK provides the ultimate gaming-on-the-go experience. In a collaborative effort, the G550JK was used to scale Mt. Elbert, the highest peak of the Rocky Mountains, in an attempt to set the world record for highest elevation LAN party.
Powerful, stylish, and feature-heavy
The G550JK may be compact, slim and portable, but it packs a big punch. ASUS TurboMaster technology, along with dual fans and copper heatsinks, allow the NVIDIA GeForce GTX 850M GPU to be safely overclocked by up to 5%. Meanwhile, Optimus support maximizes battery life when not running GPU-demanding applications. .
The sleek low-profile aluminum lines of G550JK are enhanced by the signature ROG color scheme of black with fine red diamond-cut detailing. The red backlight of the seamless one-piece hiclet keyboard makes it easy on the eyes when gaming in darkened environments while the subtly illuminated ROG logo on the lid adds a touch of exclusivity and makes sure opponents know exactly what they’re up against. Measuring just 1.1-inch at the thickest point, G550JK can go anywhere, and win everywhere.
The G550JK’s packs a 15.6-inch Full HD IPS LED-backlit display provides a stunning visual experience with its wide 178-degree viewing angles and anti-glare coating for comfort during long gaming sessions. The included 802.11ac WiFi ensures ultra-fast ping times and transfer rates to deliver the best wireless gaming when paired with an 802.11ac router. ASUS SonicMaster Premium, incorporating ICEpower, Bang & Olufsen technology and an external SonicMaster subwoofer, gives the G550JK powerful high-fidelity audio and added bass for a more immersive gaming experience.
The G550JK on a quest for a world record
HighLANder, an event hosted by Linus Media Group and Tek Syndicate on June 23rd, 2014 in Leadville Colorado, used the ROG G550JK gaming notebook to scale Mt. Elbert, the highest peak of the Rocky Mountains at 14,440 ft., followed by wirelessly connecting via an ASUS RT-AC68U router at the summit in order to set a world record for highest elevation LAN party. The elevation was certified by expert witness Elizabeth Thompson, a PHD student in Atmospheric Meteorology, and has been submitted to the Guinness Book of World Records for review and certification. Ten G550JK notebooks were used to accomplish the feat and along with 13 participants from LinusTechTips, Tek Syndicate, Newegg TV, and ASUS.
Maxwell and Kepler and...Fermi?
Covering the landscape of mobile GPUs can be a harrowing experience. Brands, specifications, performance, features and architectures can all vary from product to product, even inside the same family. Rebranding is rampant from both AMD and NVIDIA and, in general, we are met with one of the most confusing segments of the PC hardware market.
Today, with the release of the GeForce GTX 800M series from NVIDIA, we are getting all of the above in one form or another. We will also see performance improvements and the introduction of the new Maxwell architecture (in a few parts at least). Along with the GeForce GTX 800M parts, you will also find the GeForce 840M, 830M and 820M offerings at lower performance, wattage and price levels.
With some new hardware comes a collection of new software for mobile users, including the innovative Battery Boost that can increase unplugged gaming time by using frame rate limiting and other "magic" bits that NVIDIA isn't talking about yet. ShadowPlay and GameStream also find their way to mobile GeForce users as well.
Let's take a quick look at the new hardware specifications.
|GTX 880M||GTX 780M||GTX 870M||GTX 770M|
|GPU Code name||Kepler||Kepler||Kepler||Kepler|
|Rated Clock||954 MHz||823 MHz||941 MHz||811 MHz|
|Memory||Up to 4GB||Up to 4GB||Up to 3GB||Up to 3GB|
|Memory Clock||5000 MHz||5000 MHz||5000 MHz||4000 MHz|
Both the GTX 880M and the GTX 870M are based on Kepler, keeping the same basic feature set and hardware specifications of their brethren in the GTX 700M line. However, while the GTX 880M has the same CUDA core count as the 780M, the same cannot be said of the GTX 870M. Moving from the GTX 770M to the 870M sees a significant 40% increase in core count as well as a jump in clock speed from 811 MHz (plus Boost) to 941 MHz.
