NVIDIA GeForce GTX 970 vs NVIDIA GeForce GTX 950

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 950

The Nvidia GeForce GTX 950 is a mid-range graphics card for desktop PCs. It is based on the 28nm Maxwell GM206 chip and offers 768 shaders, 48 TMUs and 32 ROPs. The graphics memory is typically 2 GB GDDR5 with 6.6 GHz effective and a 128-bit interface.

As a novelty compared to the previous Maxwell GM204 chip, the GM206 includes the new VP7 video engine with HVEC (H.265) decoding and encoding. Furthermore, the GTX 950 supports HDMI 2.0 and HDCP 2.2 for 4K video output.

The 3D gaming performance of the GTX 950 is slightly better than the GeForce GTX 965M (33% more shaders but slower clock speed).
