NVIDIA GeForce GTX 960 vs Qualcomm Adreno 660 vs NVIDIA GeForce GTX 950

NVIDIA GeForce GTX 960

The Nvidia GeForce GTX 960 is a desktop graphics card of the upper middle class. It is based on the GM206 Maxwell chip that is produced in 28nm. The GTX960 offers 1024 shader cores, 64 TMUs and 32 ROPs (no deactivated units of the chip). The graphics memory is usually 2 or 4 GB GDDR5 (7 GHz effective clock) connected with a 128 Bit interface. 

On average the gaming performance is on a level with the AMD Radeon R9 280 and R9 285. Compared to laptop graphics cards, the 960 is slightly faster than a mobile Nvidia GeForce GTX 970M. The 970M offers more shader cores, but at a lower clock speed. The similar named GeForce GTX 960M for notebooks offers only 640 shader cores and a slightly lower core clock. The performance of the GTX 960 should be suffice for most games in full HD resolution. In our benchmarks only GTA 5 and The Witcher 3 achieved below 30 fps on average (see below for detailed benchmarks).

The GM206 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 GTX 960 also includes a H.265 capable de- and encoder as a first.

The power consumption of the GTX 960 on the desktop without load is around 10 Watt and on a similar level to the AMD counterparts. During gaming the 960 reaches around 85-100 Watt (depending on the model) which is a lot less than e.g. the Radeon R9 285 (around 170 Watt) - source tomshardware.com

Qualcomm Adreno 660

The Qualcomm Adreno 660 is a smartphone and tablet GPU that is integrated within the Qualcomm Snapdragon 888 SoC. The chip will be available from early 2020 and will be used mainly in high-end Android devices.

According to Qualcomm, the Adreno 660 GPU offers a 35% improved performance over the Adreno 650, its predecessor, which is integrated into the Snapdragon 865 SoC. Qualcomm also states that the energy efficiency improved by 20% which might be due to the new 5nm process at Samsung where the chip is produced.

The Adreno 650 supports Vulkan 1.1, DirectX 12, OpenGL ES 3.2, and OpenCL 2.0 FP. Furthermore, games and videos can use HDR10+ and Dolby Vision (with a supported display).

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).
