In terms of overall gaming performance, the graphical capabilities of the Intel Iris Pro Graphics 6200 Desktop are very slightly better than the Nvidia GeForce GT 640 v3 Zotac 2GB Edition.

The GT 640 has a 746 MHz higher core clock speed and 8 more Texture Mapping Units than the Pro Graphics. This results in the GT 640 providing 14.3 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 GT 640 has a 746 MHz higher core clock speed and 6 more Render Output Units than the Pro Graphics. This results in the GT 640 providing 7.8 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 Pro Graphics was released over a year more recently than the GT 640, and so the Pro Graphics is likely to have better driver support, meaning it will be more optimized for running the latest games when compared to the GT 640.

The GT 640 has 1920 MB more video memory than the Pro Graphics, so is likely to be much better at displaying game textures at higher resolutions. This is supported by the fact that the GT 640 also has superior memory performance overall.

The GT 640 has 25.2 GB/sec greater memory bandwidth than the Pro Graphics, which means that the memory performance of the GT 640 is slightly better than the Pro Graphics.

The Iris Pro Graphics 6200 Desktop has 48 Shader Processing Units and the GeForce GT 640 v3 Zotac 2GB Edition has 384. However, the actual shader performance of the Pro Graphics is 55 and the actual shader performance of the GT 640 is 402. The GT 640 having 347 better shader performance and an altogether better performance when taking into account other relevant data means that the GT 640 delivers a noticeably smoother and more efficient experience when processing graphical data than the Pro Graphics.

The Pro Graphics transistor size technology is 14 nm (nanometers) smaller than the GT 640. This means that the Pro Graphics is expected to run slightly cooler and achieve higher clock frequencies than the GT 640.

The Iris Pro Graphics 6200 Desktop requires 65 Watts to run and the GeForce GT 640 v3 Zotac 2GB Edition requires 49 Watts. We would recommend a PSU with at least 300 Watts for the Pro Graphics and a PSU with at least 350 Watts for the GT 640. The Pro Graphics requires 16 Watts more than the GT 640 to run. The difference is not significant enough for the Pro Graphics to have a noticeably larger impact on your yearly electricity bills than the GT 640.

GPU Mini Review

Mini ReviewOverview
Intel Iris Pro Graphics 6200 Desktop are Integrated Graphics in some of Intel's Broadwell Processors.

The Broadwell GT3e Core includes support for DirectX 11.2, OpenCL 1.2 and OpenGL 4.3. Additionally, it also offers better Decoding Performance, when compared to its Predecessors.

It equips a GPU Codenamed GT3e which offers 48 Shader Processing Units, 8 TMUs and 2 ROPs. The Central Unit Initially Runs at 300MHz and goes up to 1150MHz, in Turbo Mode.

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 933MHz.
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.

System Suggestions
We recommend 4GB of RAM for a system with Intel Iris Pro Graphics 6200 Desktop.
GeForce GT 640 v3 Zotac 2GB Edition is a special edition of NVIDIA's Middle-Class GeForce GT 640 v3, created by Zotac.

Overclock: Central Unit
The Central Unit runs at the same speed.

Overclock: Memory Clock
The Operating Memory Clock and the Frame Buffer remain the same.

Cooling Solution
The Cooling System has been replaced by Zotac's Silent Cooling Solution.

Without Overclocking Out of The Box, GeForce GT 640 v3 Zotac 2GB Edition is as fast as the reference GeForce GT 640 v3.
