In terms of overall gaming performance, the graphical capabilities of the Nvidia GeForce GTX 660M are massively better than the AMD Radeon HD 7500G.

The Radeon HD 7500G was released less than a year after the GeForce GTX 660M, and so they are likely to have similar driver support for optimizing performance when running the latest games.

The GeForce GTX 660M has 2048 MB video memory, but the Radeon HD 7500G does not have an entry, so the two GPUs cannot be reliably compared in this area.

The Radeon HD 7500G has 256 Shader Processing Units and the GeForce GTX 660M has 384. However, the actual shader performance of the Radeon HD 7500G is 84 and the actual shader performance of the GeForce GTX 660M is 365. The GeForce GTX 660M having 281 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 Radeon HD 7500G.

The Radeon HD 7500G requires 17 Watts to run and the GeForce GTX 660M requires 50 Watts. The GeForce GTX 660M requires 33 Watts more than the Radeon HD 7500G 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 Radeon HD 7500G.

GPU Mini Review

Mini ReviewRadeon HD 7500G is an integrated GPU on the entry-level ULV Trinity CPUs.
It's based on the 32nm Terascale 3 architecture and offers 256 Shader Processing Units, 16 TMUs and 8 ROPs. The memory interface will depend on whether or not the laptop's system RAM is dual channelled (128-bit if so, 64-bit, if not) and the operating memory clock can be up to 667MHz (max speed supported by the CPU). The central unit runs at 327MHz and will go up to 424MHz in Turbo Mode. Expect a TDP of up to 17 Watt.
Its performance is below Intel HD 4000 Graphics but is slightly above next in series - Radeon HD 7520G, despite the naming, due to the extra Shaders which prove useful in most of today's modern games.
Most of today's modern games will have to be played at the lowest settings, while extremely demanding games (e.g. Crysis 3) are most likely unplayable.
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.
