In terms of overall gaming performance, the graphical capabilities of the Nvidia GeForce GTX 980 4GB SLI are massively better than the Intel Iris i5 5675C.

The GTX 980 has a 826 MHz higher core clock speed and 248 more Texture Mapping Units than the Iris i5 5675C. This results in the GTX 980 providing 285.9 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 826 MHz higher core clock speed and 126 more Render Output Units than the Iris i5 5675C. This results in the GTX 980 providing 143.5 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 Iris i5 5675C 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.

The GTX 980 has 8064 MB more video memory than the Iris i5 5675C, 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 436 GB/sec greater memory bandwidth than the Iris i5 5675C, which means that the memory performance of the GTX 980 is massively better than the Iris i5 5675C.

The Iris i5 5675C has 48 Shader Processing Units and the GeForce GTX 980 4GB SLI has 4096. However, the actual shader performance of the Iris i5 5675C is 53 and the actual shader performance of the GTX 980 is 6724. The GTX 980 having 6671 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 Iris i5 5675C.

The Iris i5 5675C transistor size technology is 14 nm (nanometers) smaller than the GTX 980. This means that the Iris i5 5675C is expected to run slightly cooler and achieve higher clock frequencies than the GTX 980.

The Iris i5 5675C requires 65 Watts to run and the GeForce GTX 980 4GB SLI requires 350 Watts. We would recommend a PSU with at least 300 Watts for the Iris i5 5675C and a PSU with at least 750 Watts for the GTX 980. The GTX 980 requires 285 Watts more than the Iris i5 5675C 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 Iris i5 5675C.

GPU Mini Review

Mini ReviewOverview
Intel Iris i5 5675C is the Specific Version of Intel Iris Pro Graphics 6200 Desktop that is Integrated in the Core i5-5675C Processor.

GPU
The Central Unit Initially Runs at 300MHz and goes up to 1100MHz, in Turbo Mode.

Memory
Unlike the common Integrated Graphics Cards, this one has access to a dedicated frame buffer of 128MB of eDRAM.
The GPU also Shares the System's RAM which varies from laptop to laptop. Typically, the GPU reserves 1GB. Depending on whether or not the system's RAM is Dual-Channeled, it can access either a 64-bit or 128-bit memory interface. The operating memory clock also depends on the at which speed the System's RAM is running and is limited by the highest operating speed that the Processor supports. In this case, it is 800MHz.
It is then obvious the Memory Bandwidth depends on a lot of factors and thus this Graphics Card performance may vary heavily from system to system.

Performance
Benchmarks Indicate Performance around of a Dedicated GeForce 940M.

System Suggestions
We recommend 4GB of RAM for a system with Intel Iris HD i5 5675C.
Overview
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.
