In terms of overall gaming performance, the graphical capabilities of the Nvidia GeForce GTX 660M are massively better than the Intel HD Graphics Mobile (Braswell).

The GeForce GTX 660M has a 515 MHz higher core clock speed and 28 more Texture Mapping Units than the Graphics Mobile. This results in the GeForce GTX 660M providing 25.4 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 GTX 660M has a 515 MHz higher core clock speed and 15 more Render Output Units than the Graphics Mobile. This results in the GeForce GTX 660M providing 13.1 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 Graphics Mobile was released over three years more recently than the GeForce GTX 660M, and so the Graphics Mobile 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 2048 MB video memory, but the Graphics Mobile does not have an entry, so the two GPUs cannot be reliably compared in this area.

The HD Graphics Mobile (Braswell) has 16 Shader Processing Units and the GeForce GTX 660M has 384. However, the actual shader performance of the Graphics Mobile is 90 and the actual shader performance of the GeForce GTX 660M is 365. The GeForce GTX 660M having 275 better shader performance and an altogether better performance when taking into account other relevant data means that the GeForce GTX 660M delivers a significantly smoother and more efficient experience when processing graphical data than the Graphics Mobile.

The Graphics Mobile transistor size technology is 14 nm (nanometers) smaller than the GeForce GTX 660M. This means that the Graphics Mobile is expected to run slightly cooler and achieve higher clock frequencies than the GeForce GTX 660M.

The HD Graphics Mobile (Braswell) requires 6 Watts to run and the GeForce GTX 660M requires 50 Watts. The GeForce GTX 660M requires 44 Watts more than the Graphics Mobile to run. The difference is significant enough that the GeForce GTX 660M may have a slight adverse affect on your yearly electricity bills in comparison to the Graphics Mobile.

GPU Mini Review

Mini ReviewOverview
Intel HD Graphics Mobile (Braswell) are Integrated Graphics in some of Intel's SoC Braswell Processors.

Architecture
The Braswell Core includes support for DirectX 11.2, OpenCL 2.0 and OpenGL 4.3. Additionally, it also offers better Decoding Performance, when compared to its Predecessors.
The GPU Codenamed GT1 offers 16 Shader Processing Units, 4 TMUs and 1 ROP.

GPU
The Central Unit Initially Runs at 320MHz and goes up to 720MHz, in Turbo Mode.

Memory
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 800MHz.
Depending on whether or not the System's RAM is Dual-Channeled, it can access either a 64-bit or 128-bit Memory Interface.

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

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 GT 520M.

System Suggestions
Intel HD Graphics Mobile (Braswell) 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.
