In terms of overall gaming performance, the graphical capabilities of the Pro Graphics and the GeForce GTX 660M are equal.

The GeForce GTX 660M has a 535 MHz higher core clock speed and 24 more Texture Mapping Units than the Pro Graphics. This results in the GeForce GTX 660M providing 24.3 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 GeForce GTX 660M has a 535 MHz higher core clock speed and 14 more Render Output Units than the Pro Graphics. This results in the GeForce GTX 660M providing 12.8 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 three years more recently than the GeForce GTX 660M, and so the Pro Graphics is likely to have far better driver support, meaning it will be much more optimized and ultimately superior to the GeForce GTX 660M when running the latest games.

The GeForce GTX 660M 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 GTX 660M also has superior memory performance overall.

The GeForce GTX 660M has 34.1 GB/sec greater memory bandwidth than the Pro Graphics, which means that the memory performance of the GeForce GTX 660M is noticeably better than the Pro Graphics.

The Iris Pro Graphics 6200 Mobile has 48 Shader Processing Units and the GeForce GTX 660M has 384. However, the actual shader performance of the Pro Graphics is 442 and the actual shader performance of the GeForce GTX 660M is 365. The Pro Graphics having 77 better shader performance is not particularly notable, as altogether the GeForce GTX 660M performs better when taking into account other relevant data.

The Pro Graphics transistor size technology is 14 nm (nanometers) smaller than the GeForce GTX 660M. This means that the Pro Graphics is expected to run slightly cooler and achieve higher clock frequencies than the GeForce GTX 660M. While they exhibit similar graphical performance, the Pro Graphics should consume less power than the GeForce GTX 660M.

The Iris Pro Graphics 6200 Mobile requires 47 Watts to run and the GeForce GTX 660M requires 50 Watts. The GeForce GTX 660M requires 3 Watts more than the Pro Graphics to run. The difference is not significant enough for the GeForce GTX 660M to have a noticeably larger impact on your yearly electricity bills than the Pro Graphics.

GPU Mini Review

Mini ReviewOverview
Intel Iris Pro Graphics 6200 Mobile are Integrated Graphics in some of Intel's HQ Haswell Processors.

Architecture
The Broadwell Architecture Succeeds the Haswell Architecture and offers Faster & More Efficient Integrated Graphics. Additionally, it also offers better Decoding Performance, when compared to its Predecessors.
The GPU Codenamed GT3-U offers 48 Shader Processing Units, 8 TMUs and 2 ROPs.

GPU
The Central Unit Initially Runs at 300MHz and goes up to 1150MHz, 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.
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 128MB 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 2GB.

Performance
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 940M.

System Suggestions
Iris Pro Graphics 6200 Mobile is best suited for resolutions up to and including 1366x768. We recommend 4GB of RAM for Optimal Performance.
Overview
GeForce GTX 660M is a Fast-Middle-Class Mobile Graphics Card based on the first revision of the Kepler Architecture.

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.

GPU
It equips a GPU Codenamed GK107-N13E-GE-A2 which has 2 Stream Multiprocessors activated and thus offers 384 Shader Processing Units, 32 TMUs and 16 ROPs. The Central Unit is initially clocked at 835MHz and goes up to 950MHz, in Turbo Mode.

Memory
The GPU accesses a 2GB frame buffer of fast GDDR5, through a 128-bit memory interface. The size of the frame buffer is exaggerated and no way benefits the GPU. The Memory Clock Operates at 1000MHz.

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

Power Consumption
With a rated board TDP of 45W, it is suited for average sized laptops.

Performance
Gaming benchmarks indicate its performance is not too far from the desktop GeForce GTX 650.

System Suggestions
We recommend a decent processor (Intel Core i5 Mobile) and 8GB of RAM for a system with GeForce GTX 660M.
