The NVIDIA GeForce GTX 970M SLI is a high-end DirectX 11-compatible graphics solution for laptops, consisting of two GeForce GTX 970M. Each card has a 28 nm GM204 GPU based on the Maxwell architecture, which is the same chip as found on the GTX 980M as well as several desktop cards. The clocks for the SLI-setup are usually identical to a single GTX 970M (924 MHz GPU, 1250 MHz memory).

With SLI, each card renders a single frame (AFR mode). Therefore, it may suffer from micro stuttering in low fps ranges of 30 fps. This happens because of different timespans between two frames (e.g., irregular delays between sequential frames).


GM204 is based on Nvidia's Maxwell architecture, which replaces the previous Kepler generation. Among other changes, Nvidia have restructured the streaming multi processors (SMM) in order to increase workload and efficiency. Now each SMM contains only 128 shader units and 8 TMUs, which is noticeably less than an equivalent Kepler GPU. The GM204 features four GPCs, and each consists of four SMMs. But, in the GeForce GTX 970M, Nvidia have deactivated 6 of 16 SMMs. As a result, only 1280 shader ALUs and 80 TMUs are active. In addition, there are 48 ROPs in three clusters with 16 units each.

The memory interface has a bandwidth of 192-bits (3x 64 bit) for each of the two GPUs. Thanks to an improved compression algorithm, the connection to the GDDR5 memory should be significantly more efficient per MHz. Furthermore, the L1 (96 KB per SMM) and L2 caches (2 MB) have been significantly increased to lower the needed bandwidth. Compared to the mid-range GM107, the newer and larger GM204 has several additional features and changes. Aside from the improved polymorphic engine in the SSMs, it is also the first Nvidia chip to support DirectX 12 Feature Level 12_1.


With good driver support, SLI almost doubles the performance of a single card. The GTX 970M SLI outperforms the former GeForce GTX 880M SLI by about 10 percent and is the second fastest mobile graphics solution in late 2014. Only the significantly more expensive GTX 980M SLI offers even more 3D power and is about 30 percent faster. Nevertheless, the GTX 970M SLI is powerful enough to run even the most demanding games with highest details, AA/AF and resolutions exceeding FullHD.


Most of the features are identical to the GeForce GTX 800M series. With the GTX 970M, there can be up to 4 active displays possible, but this will likely decrease due to Optimus. Displays can be connected with a maximum resolution of 3840 x 2160 pixels via DisplayPort 1.2 or HDMI 2.0 (no HDCP @ 4K). HD audio formats like Dolby True HD and DTS HD can be sent to a compatible receiver as bitstream. As with previous models, 3D Vision is not supported with Optimus.

The updated video processor VP6 supports the usual formats like H.264 and can also decode and encode H.265 with a resolution of up to 4K via the NVENC API. Several parallel streams, such as picture-in-picture in a Blu-Ray movie, are also possible.

Further features of the GTX 900M series, which are also partly supported by older cards, include Battery Boost (longer battery life during gaming), Shadowplay (recording of gaming videos up to 4K60p and 130 Mbit/s) and Gamestream (game streaming on Shield console). More information on these features are available here.

Power Consumption

The power consumption of each GeForce GTX 970M including its MXM board and memory should be similar to a GTX 870M with a specified TDP of 100 W, leading to a total TDP of about 200 W. Given the significantly higher performance, this can be considered a massive increase in performance-per-watt. Nevertheless, the SLI setup can only be used in very large and heavy gaming notebooks with powerful cooling systems. Under low load, dynamic clock rates help the GPUs to save energy.
