The NVIDIA GeForce GTX 970M is a 28 nm DirectX-11 graphics card for high-end notebooks. It was introduced in Fall of 2014 and is based on the Maxwell GM204 architecture. The clock rates specified by Nvidia are 924 MHz (+ Boost) for the GPU and 1250 MHz (5000 MHz effective) for the up to 6 GB of GDDR5 memory.

Architecture

Just like the mid-range GM107 chip (GeForce GTX 860M), the GM204 is also based on Nvidia's new 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). 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.

Although the GM107 and the GM204 both belong to the Maxwell generation, 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.

Performance

Thanks to the increased efficiency, the GeForce GTX 970M performs somewhat better than the former top model, the GTX 880M and should sit comfortably as the second fastest model after the GTX 980M. According to our benchmarks, it is about 15 % faster than the GTX 880M depending on the scenario. The GTX 980M is a further 20 to 30 percent faster than the GTX 970M. Overall, the GTX 970M is fast enough to run even the most demanding games with highest details and FullHD resolution. Additional quality features like anti-aliasing and anisotropic filtering are also not a problem for this card in most titles as of 2014.

The NVIDIA GeForce GTX 970M is a high end DirectX 11.2 graphics card for laptops. The card is not yet officially announced and therefore the following information is based on rumors and leaks. The card based on the GM204 Maxwell chip, that is already available in the desktop GeForce GTX 970 and 980. Thanks to the improved efficiency, the GTX970M should be clearly faster than the previous GTX 870M and even the old GTX 880M.
