In terms of overall gaming performance, the graphical capabilities of the Nvidia GeForce GTX 980 4GB SLI are massively better than the Nvidia GeForce GTX 550 Ti Zotac Edition.

The GTX 980 has a 226 MHz higher core clock speed and 224 more Texture Mapping Units than the GTX 550 Ti. This results in the GTX 980 providing 259.5 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 226 MHz higher core clock speed and 104 more Render Output Units than the GTX 550 Ti. This results in the GTX 980 providing 122.5 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 980 was released over three years more recently than the GTX 550 Ti, and so the GTX 980 is likely to have far better driver support, meaning it will be much more optimized and ultimately superior to the GTX 550 Ti when running the latest games.

The GTX 980 has 7168 MB more video memory than the GTX 550 Ti, 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 350.4 GB/sec greater memory bandwidth than the GTX 550 Ti, which means that the memory performance of the GTX 980 is massively better than the GTX 550 Ti.

The GeForce GTX 980 4GB SLI has 4096 Shader Processing Units and the GeForce GTX 550 Ti Zotac Edition has 192. However, the actual shader performance of the GTX 980 is 6724 and the actual shader performance of the GTX 550 Ti is 346. The GTX 980 having 6378 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 550 Ti.

The GTX 980 transistor size technology is 12 nm (nanometers) smaller than the GTX 550 Ti. This means that the GTX 980 is expected to run slightly cooler and achieve higher clock frequencies than the GTX 550 Ti.

The GeForce GTX 980 4GB SLI requires 350 Watts to run and the GeForce GTX 550 Ti Zotac Edition requires 116 Watts. We would recommend a PSU with at least 750 Watts for the GTX 980 and a PSU with at least 400 Watts for the GTX 550 Ti. The GTX 980 requires 234 Watts more than the GTX 550 Ti 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 550 Ti.

GPU Mini Review

Mini ReviewOverview
GeForce GTX 980 4GB SLI is a solution of two GeForce GTX 980 4GB put together using NVIDIA's SLI technology.

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.

GPU
It consists of 2 GPUs codenamed GM204-400-A1 which, together, offer 4096 Shader Processing Units, 256 TMUs and 128 ROPs, on a 512-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.

Power Consumption
Power Consumption lies between 300W and 400W.

Performance
Gaming benchmarks prove that at 4K (3840x2160) GeForce GTX 980 4GB SLI is over 7% faster than AMD's Radeon R9 295X2.

System Suggestions
We recommend a very strong processor (Intel Core i7 Six Core/AMD FX Eight Core) and 16GB of RAM for a system with GeForce GTX 980 4GB SLI.
GeForce GTX 550 Ti Zotac Edition is a special edition of fast-middle-class GeForce GTX 550 Ti that features a new cooling system and nothing else. Therefore, its performance is exactly like the reference GeForce GTX 550 Ti created by NVIDIA.
Some modern demanding games will run at the highest settings using a 1080p resolution but the largest part will have to be played with a 720p resolution to be played optimally.
This Graphics Card needs to be paired with a decent Quad Core CPU.
