In terms of overall gaming performance, the graphical capabilities of the Nvidia GeForce GTX 660 MSI OC 2GB Edition are massively better than the Intel Iris Graphics 5100 Desktop.

The GTX 660 has a 606 MHz higher core clock speed and 72 more Texture Mapping Units than the Graphics 5100. This results in the GTX 660 providing 77.3 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 660 has a 606 MHz higher core clock speed and 20 more Render Output Units than the Graphics 5100. This results in the GTX 660 providing 22.5 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 Graphics 5100 was released less than a year after the GTX 660, and so they are likely to have similar driver support for optimizing performance when running the latest games.

The GTX 660 has 2048 MB video memory, but the Graphics 5100 does not have an entry, so the two GPUs cannot be reliably compared in this area.

The Iris Graphics 5100 Desktop has 160 Shader Processing Units and the GeForce GTX 660 MSI OC 2GB Edition has 960. However, the actual shader performance of the Graphics 5100 is 314 and the actual shader performance of the GTX 660 is 1029. The GTX 660 having 715 better shader performance and an altogether better performance when taking into account other relevant data means that the GTX 660 delivers a massively smoother and more efficient experience when processing graphical data than the Graphics 5100.

The Graphics 5100 transistor size technology is 6 nm (nanometers) smaller than the GTX 660. This means that the Graphics 5100 is expected to run very slightly cooler and achieve higher clock frequencies than the GTX 660.

The Iris Graphics 5100 Desktop requires 28 Watts to run but there is no entry for the GeForce GTX 660 MSI OC 2GB Edition.

GPU Mini Review

Mini ReviewIris Graphics 5100 Desktop are found in some of the 2013 Haswell desktop processors.
They feature 40 Execution Units (160 Shader Processing Units), 8 TMUs and 4 ROPs. They share system memory and so the memory channel and speed will depend on the users configuration. The best possible combination is a dual-channel bus-width with an operating memory clock of 800MHz.
Its central unit and turbo frequency also depend on the CPU its embedded but it ranges from 400MHz to 1350MHz.
Its performance is average and only somewhat better than what dedicated GeForce GT 630 & Radeon 6570 offer.
GeForce GTX 660 MSI OC 2GB Edition is a special edition of GeForce GTX 660.
The new features include the Propeller Blade Technology solution which generates 20% more airflow than traditional fan design, according to MSI.
In terms of overclocking, the base-clock was increased from 980MHz to 1006MHz and the boost clock can now reach 1072MHz, instead of 1033MHz. The memory clock was left untouched.
The overclocking is therefore somewhat significant and the performance boost is around 5% when compared to the standard GeForce GTX 660.
