<p align="center"> </p><p><p>Today NVIDIA officially launched their latest mobile GPUs, the GTX 960M and 950M; on a quieter note, the 940M, 930M, and 920M also showed up. NVIDIA launched the high-end GM204 back in September/October last year and brought out the mobile GTX 970M and 980M using the chips, and they more recently launched the desktop GTX 960 using a new GM206 part with up to 1024 CUDA cores. Considering the GTX 965M has 1024 CUDA cores many felt it would use GM206 as well, but that didn’t happen; in a similar fashion, those expecting (hoping) GTX 960M and 950M would use a derivative of GM206 are also going to be disappointed and it continues to use the GM107 chip.</p>
<p>The new GeForce GTX 960M and 950M end up being clock speed bumps from the existing GTX 860M/850M, though this time the 960M is purely Maxwell based and there’s no Kepler alternative. The GTX 950M has 640 CUDA cores running at 914MHz (+ Boost), and it can be paired with either DDR3-2000 (yuck!) or GDDR5-5000, both using a 128-bit interface. While the additional bandwidth of GDDR5 may not matter too much at lower resolutions, we’ve seen in the past that it can have a significant impact on performance at 1080p and medium or higher settings. Interestingly, the clocks and core configurations mean that in practice, GTX 950M is actually a bit slower than GTX 850M (640 cores at 936MHz + Boost). 960M meanwhile represents a minor bump in clock speeds over GTX 860M, going from 1029MHz + Boost to 1096MHz + Boost; the RAM stays the same with GDDR5-5000 providing 80GB/s of bandwidth.</p>
<p>NVIDIA’s product pages for the three lower tier GPUs reveal precious little in the way of specifications; all we know is that the parts are DirectX 12 capable and that the 920M is rated as being ~3X the performance of Intel’s HD 4400 while the 930M and 940M are 3.5X and 4X the performance rating of the HD 4400. Given the performance and other information available, however, it’s pretty clear that these are all derived from GM108 and will replace the existing 840M/830M/820M. Again, there may be a performance regression going from the 840M to the 940M, as NVIDIA’s specifications rate the 840M at 5.0X the performance of the HD 4400, or else NVIDIA has simply changed the performance score calculations. On paper, it looks like the 920M replaces the 830M with the 930M offering an in-between SKU. We’ve asked for additional information on clock speeds and core counts, but NVIDIA may not elect to provide those.</p>
<p>Here are the full specifications for the old and new GM107 based parts, the GeForce GTX 960M/950M and the 860M/850M:</p>

<p>Along with the new parts, NVIDIA and their partners have announced several new laptops using the “new” GPUs. Below are images of the new Acer Nitro V, Alienware 13, ASUS G501, HP Omen, and Lenovo Y50. Obviously there won’t be a major difference in performance between the new GTX 900M parts and the existing GTX 800M parts, so this is most likely just NVIDIA aligning the product names for use with the upcoming Broadwell systems.</p>
