In terms of overall gaming performance, the graphical capabilities of the Nvidia GeForce GTX 980 4GB are significantly better than the Nvidia GeForce GTX 950 Asus OC 2GB Edition.

The GTX 980 has a 24 MHz higher core clock speed and 80 more Texture Mapping Units than the GTX 950. This results in the GTX 980 providing 91.2 GTexel/s better texturing performance. This still holds weight but shader performance is generally more relevant, particularly since both of these GPUs support at least DirectX 10.

The GTX 980 has a 24 MHz higher core clock speed and 32 more Render Output Units than the GTX 950. This results in the GTX 980 providing 36.8 GPixel/s better pixeling performance. However, both GPUs support DirectX 9 or above, and pixeling performance is only really relevant when comparing older cards.

The GTX 950 was released less than a year after the GTX 980, and so they are likely to have similar driver support for optimizing performance when running the latest games.

Both GPUs exhibit very powerful performance, so it probably isn't worth upgrading from one to the other, as both are capable of running even the most demanding games at the highest settings.

The GTX 980 has 2048 MB more video memory than the GTX 950, so is likely to be much better at displaying game textures at higher resolutions. This is supported by the fact that the GTX 980 also has superior memory performance overall.

The GTX 980 has 118.6 GB/sec greater memory bandwidth than the GTX 950, which means that the memory performance of the GTX 980 is massively better than the GTX 950.

The GeForce GTX 950 Asus OC 2GB Edition has 768 Shader Processing Units and the GeForce GTX 980 4GB has 2048. However, the actual shader performance of the GTX 950 is 1326 and the actual shader performance of the GTX 980 is 3362. The GTX 980 having 2036 better shader performance and an altogether better performance when taking into account other relevant data means that the GTX 980 delivers a massively smoother and more efficient experience when processing graphical data than the GTX 950.

The GeForce GTX 950 Asus OC 2GB Edition requires 75 Watts to run and the GeForce GTX 980 4GB requires 165 Watts. We would recommend a PSU with at least 350 Watts for the GTX 950 and a PSU with at least 500 Watts for the GTX 980. The GTX 980 requires 90 Watts more than the GTX 950 to run. The difference is significant enough that the GTX 980 may have an adverse affect on your yearly electricity bills in comparison to the GTX 950.

GPU Mini Review

Mini ReviewOverview
GeForce GTX 950 Asus OC 2GB Edition is a Special Edition of NVIDIA's Fast-Middle-Class GeForce GTX 950 2GB, created by Asus.

Overclock: Central Unit
The Central Unit is now of 1102MHz, instead of 1024MHz, while the Boost Clock achieves 1317MHz, instead of 1279MHz.

Overclock: Memory Clock
None.

Frame Buffer

Cooling Solution
Twin optimized fans carefully selected by engineers drive 2X greater airflow while maintaining 3X quieter performance, combining enhanced cooling with a more pleasant gaming and computing environment.

Performance
Benchmarks Indicate a 4% Performance Boost over the Reference GeForce GTX 950 2GB.
Overview
GeForce GTX 980 4GB is a high-end Graphics Card based on the second revision of the Maxwell architecture. It surpassed previous GeForce GTX 780 Ti and cost less. It was also much more energy efficient. Read below to know more.

Architecture
The Second variant of the Maxwell Architecture, despite being also manufactured with a 28nm technology, has an extremely large L2 Cache and features a Third Generation Delta Color Compression which allows NVIDIA to produce Graphics Cards with relatively small memory data transfer rates, without causing too much impact on the overall performance. Furthermore, the Shaders have been redesigned and are both more powerful and energy efficient.
The Second Revision of Maxwell also adds VXGI (Voxel Global Illumination) which makes scenes significantly more lifelike and believable as light interacts more realistically in the game environment and the MFAA technology which provides the same effect as MSAA but at a much lower performance cost.

GPU
It equips a GPU codenamed GM204-400-A1 which has 16 SM activated and thus 2048 Shader Processing Units, 128 TMUs and 64 ROPs, on a 256-bit memory interface of fast GDDR5. The central unit runs at 1126MHz and goes up to 1216MHz, in Turbo Mode, while the memory clock operates at 1753MHz.

Features
DirectX 12.0 Support (11.0 Hardware Default) and support for SLI, VXGI, MFAA, GameStream, G-SYNC, GPU Boost 2.0, GeForce Experience, PhysX and other technologies.

Cooling Solution
The Cooling Solution consists of a Single-Fan and is identical to the one seen on GeForce GTX 780. The Card is known to run cool and has a maximum operating temperature of 98ÂșC.

Power Consumption
With a rated board TDP of 165W, it requires at least a 500W PSU with two 6-pin connectors.

Release Price
The release price of $550 is lower than of its predecessor - GeForce GTX 780 which was launched for $649.

Performance
Gaming benchmarks prove that at 4K (3840x2160) GeForce GTX 980 4GB is over 20% faster than its predecessor and even beats GeForce GTX 780 Ti in about 7%.

System Suggestions
GeForce GTX 980 4GB is best suited for resolutions up to and including 2560x1440. We recommend a Very Strong Processor and 8GB of RAM for Optimal Performance.
