In terms of overall gaming performance, the graphical capabilities of the Intel Iris Pro Graphics 5200 Mobile are very slightly better than the Nvidia GeForce GT 640M.

The GeForce GT 640M has a 425 MHz higher core clock speed and 24 more Texture Mapping Units than the Pro Graphics. This results in the GeForce GT 640M providing 18.4 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 GeForce GT 640M has a 425 MHz higher core clock speed and 14 more Render Output Units than the Pro Graphics. This results in the GeForce GT 640M providing 9.6 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 GeForce GT 640M, 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 GeForce GT 640M.

The GeForce GT 640M 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 GeForce GT 640M also has superior memory performance overall.

The GeForce GT 640M has 16 GB/sec greater memory bandwidth than the Pro Graphics, which means that the memory performance of the GeForce GT 640M is slightly better than the Pro Graphics.

The Iris Pro Graphics 5200 Mobile has 40 Shader Processing Units and the GeForce GT 640M has 384. However, the actual shader performance of the Pro Graphics is 208 and the actual shader performance of the GeForce GT 640M is 240. The GeForce GT 640M having 32 better shader performance and an altogether better performance when taking into account other relevant data means that the GeForce GT 640M delivers a slightly smoother and more efficient experience when processing graphical data than the Pro Graphics.

The Pro Graphics transistor size technology is 6 nm (nanometers) smaller than the GeForce GT 640M. This means that the Pro Graphics is expected to run very slightly cooler and achieve higher clock frequencies than the GeForce GT 640M.

The Iris Pro Graphics 5200 Mobile requires 47 Watts to run and the GeForce GT 640M requires 32 Watts. The Pro Graphics requires 15 Watts more than the GeForce GT 640M 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 GeForce GT 640M.

GPU Mini Review

Mini ReviewOverview
Intel Iris Pro Graphics 5200 Mobile are Integrated Graphics in some of Intel's HQ Haswell Processors.

The Haswell GT3 Core includes support for DirectX 11.1, OpenCL 1.2 and OpenGL 4.0. Additionally, it also offers better Decoding Performance, when compared to its Predecessors.

It equips a GPU Codenamed GT3e which offers 40 Shader Processing Units, 8 TMUs and 2 ROPs. The Central Unit Initially Runs at 200MHz and goes up to 1300MHz, 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 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.

The Most Powerful Variant Offers Performance on level with a dedicated GeForce GT 745M.

System Suggestions
We recommend 4GB of RAM for a system with Intel Iris Pro Graphics 5200 Mobile.
GeForce GT 640M is a Middle-Class Mobile Graphics Card based on the first revision of the Kepler Architecture.

The Kepler Architecture was NVIDIA's big step to power efficiency. Each Stream Multiprocessor (SMX) now hosts 192 Shader Processing Units - against the 48 of older Fermi Architecture, and has been redesigned being now clocked at the same speed of the Central Unit. This means they are more energy efficient and will consequently lead to cooler operating temperatures. However, it also means they are weaker. It can be said that one Fermi SMX is as fast as 2 Kepler SMXs.
Additionally, and not available in all GPUs, Kepler also introduced the Boost Clock Feature. The Boost Clock is an even higher Clock Speed activated when in gaming mode and becomes the effective speed of the GPU.

It equips a GPU Codenamed GK107 which has 2 Stream Multiprocessors activated and thus offers 384 Shader Processing Units, 32 TMUs and 16 ROPs. The Central Unit is clocked at 625MHz.

The GPU accesses a 2GB frame buffer of DDR3, through a 128-bit memory interface. The size of the frame buffer is exaggerated and in no way benefits the GPU. The Memory Clock Operates at 900MHz.

DirectX 11.0 Support (11.0 Hardware Default) and support for Optimus, CUDA, OpenCL, DirectCompute, 3D Vision Surround, PhysX, Realtime Raytracing and other technologies

Power Consumption
With a rated board TDP of 33W, it is suited for small laptops.

Gaming benchmarks indicate its performance is on average with the older GeForce GTX 465M.

System Suggestions
We recommend a modest processor (Intel Core i3 Mobile) and 4GB of RAM for a system with GeForce GT 640M.
