NVIDIA GeForce GTX 970 vs NVIDIA GeForce GTX 980M vs NVIDIA GeForce GTX 980

NVIDIA GeForce GTX 970

The Nvidia GeForce GTX 970 is a high end desktop graphics card based on the Maxwell architecture. As the faster GTX 980, the GTX 970 uses the GM204 chip, but with reduced shaders (2048 vs. 1664) and TMUs (128 vs 103). The graphics card is equipped with 4 GB GDDR5 (7 GHz effective). 3.5 GB of the 4 GB are connected with 224 Bit, the rest only with a 32 Bit interface. This can lead to some stuttering or reduced frame rates in games that use the full 4 GB. The similar named mobile GeForce GTX 970M is clearly slower as it features only 1280 shader cores.

Despite the unique memory configuration, the GTX 970 performs on average on par with the older GeForce GTX 780 Ti or a AMD Radeon R9 290X.

The GM204 supports CUDA, 3D Vision, PhysX, GeForce Experience, Surround, GameStream, GPU Boost 2.0, Adaptive Vertical Sync / G-SYNC, SLI, DSR, MFAA and Virtual Reality latency improvements.

The Maxwell architecture is very power efficient. While gaming, the card only uses as much power as the Radeon R9 285 which is more than 35% slower on average.

NVIDIA GeForce GTX 980M

NVIDIA GeForce GTX 980

The NVIDIA GeForce GTX 980 is a high-end desktop graphics card based on the second generation Maxwell architecture. The GM204 chip is manufactured in 28 nm at TSMC. Compared to the older GeForce GTX 780Ti, the 980 offers similar performance levels but at reduced average power consumption. The similarly named Nvidia Geforce GTX 980M for notebooks is based on the same chip, but uses less shader cores and slower clock speeds for reduced performance. Since end of 2015, the GTX 980 is also used in laptops (same chip with same clocks and branding).

The Geforce GTX 980 supports a range of unique features like CUDA, 3D Vision, PhysX, GeForce Experience, GameStream, GPU Boost 3.0, Adaptive Vertical-Sync / G-Sync, SLI, DSR, MFAA and Virtual Reality latency improvements.
