In terms of overall gaming performance, the graphical capabilities of the Nvidia GeForce GTX 675M SLI are massively better than the Intel Iris i7 6560U.

The GTX 675M has a 320 MHz higher core clock speed and 120 more Texture Mapping Units than the Iris i7 6560U. This results in the GTX 675M providing 77 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 675M has a 320 MHz higher core clock speed and 62 more Render Output Units than the Iris i7 6560U. This results in the GTX 675M providing 39.1 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 i7 6560U was released over three years more recently than the GTX 675M, and so the Iris i7 6560U is likely to have far better driver support, meaning it will be much more optimized and ultimately superior to the GTX 675M when running the latest games.

The GTX 675M has 4096 MB video memory, but the Iris i7 6560U does not have an entry, so the two GPUs cannot be reliably compared in this area.

The Iris i7 6560U has 48 Shader Processing Units and the GeForce GTX 675M SLI has 768. However, the actual shader performance of the Iris i7 6560U is 403 and the actual shader performance of the GTX 675M is 952. The GTX 675M having 549 better shader performance and an altogether better performance when taking into account other relevant data means that the GTX 675M delivers a massively smoother and more efficient experience when processing graphical data than the Iris i7 6560U.

The Iris i7 6560U transistor size technology is 26 nm (nanometers) smaller than the GTX 675M. This means that the Iris i7 6560U is expected to run slightly cooler and achieve higher clock frequencies than the GTX 675M.

The Iris i7 6560U requires 15 Watts to run and the GeForce GTX 675M SLI requires 200 Watts. The GTX 675M requires 185 Watts more than the Iris i7 6560U to run. The difference is significant enough that the GTX 675M may have an adverse affect on your yearly electricity bills in comparison to the Iris i7 6560U.

GPU Mini Review

Mini ReviewOverview
Intel Iris i7 6560U is the specific version of Intel HD Graphics 540 Mobile that is integrated in the Core i7-6560U Processor..

The Skylake Architecture succeeds the Broadwell Architecture and aims for increased CPU and Graphics Performance, within the same Power Requirements. It includes support for DirectX 12.1, OpenCL 2.0 and OpenGL 4.4, as well as DDR4 Memory Support.
The GPU Codenamed GT3-U offers 48 Shader Processing Units, 8 TMUs and 2 ROPs.

The Central Unit Initially Runs at 350MHz and goes up to 1050MHz, in Turbo Mode.

Memory: Speed
The Operating Memory Clock depends at which speed the System's RAM is running and which Memory Type is installed and is ultimately limited by the highest operating speed that the Processor supports. In this case, it is 933MHz for DDR3 and 1067MHz for DDR4.
Depending on whether or not the System's RAM is Dual-Channeled, it can access either a 64-bit or 128-bit Memory Interface.
An addition to the Iris Graphics is the access to a L4 Cache of 64MB eDRAM which further increases the Memory Performance.

Memory: Frame Buffer
The GPU Shares the System's RAM which varies according to the System. The GPU may reserve up to 1.7GB.

Because Performance depends heavily on the Memory Bandwidth, it may vary heavily from System to System.
Best Case Scenario, expect Performance Identical to a dedicated GeForce 830M.

System Suggestions
Iris i7 6560U is best suited for resolutions up to and including 1366x768. We recommend 4GB of RAM for Optimal Performance.
GeForce GTX 675M SLI is a solution of two GeForce GTX 675M put together using NVIDIA'S SLI technology.
Check the page of GeForce GTX 675M to know more about its chip.
As usual, SLI relies a lot on proper driver support and may suffer from micro-stuttering in lower frame rates (below 30). Benchmarks indicate the performance is overall, about 35% better than a single GeForce GTX 675M performing by itself but at times (depending whether or not the 3D game supports SLI or in the graphics driver) it performed worse than a single GeForce GTX 675M.
Even the most demanding games will run at the highest settings.
