In terms of overall gaming performance, the graphical capabilities of the Nvidia GeForce GTX 660M are massively better than the AMD Mobility Radeon HD 5165.

The GeForce GTX 660M has a 235 MHz higher core clock speed and the same number of Texture Mapping Units as the Radeon HD. This results in the GeForce GTX 660M providing 7.5 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 235 MHz higher core clock speed and 8 more Render Output Units than the Radeon HD. This results in the GeForce GTX 660M providing 8.6 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 GeForce GTX 660M was released over a year more recently than the Radeon HD, and so the GeForce GTX 660M is likely to have better driver support, meaning it will be more optimized for running the latest games when compared to the Radeon HD.

The GeForce GTX 660M has 1024 MB more video memory than the Radeon HD, 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 35.2 GB/sec greater memory bandwidth than the Radeon HD, which means that the memory performance of the GeForce GTX 660M is noticeably better than the Radeon HD.

The GeForce GTX 660M has 384 Shader Processing Units and the Mobility Radeon HD 5165 has 320. However, the actual shader performance of the GeForce GTX 660M is 365 and the actual shader performance of the Radeon HD is 125. The GeForce GTX 660M having 240 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.

The GeForce GTX 660M transistor size technology is 12 nm (nanometers) smaller than the Radeon HD. This means that the GeForce GTX 660M is expected to run slightly cooler and achieve higher clock frequencies than the Radeon HD.

The GeForce GTX 660M requires 50 Watts to run and the Mobility Radeon HD 5165 requires 35 Watts. The GeForce GTX 660M requires 15 Watts more than the Radeon HD 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 Radeon HD.

GPU Mini Review

Mini ReviewOverview
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.
Mobility Radeon HD 5165 is a middle-class GPU based on the 55nm, Terascale 1 architecture and therefore not related to other Mobility HD 5000 Series GPUs.
It's based on the M96 Core and offers 320 Shader Processing Units, 32 TMUs and 8 ROPs, on 128-bit memory interface of standard GDDR3. The central unit runs at 600MHz and the memory clock operates at up to 900MHz. It consumes no more than 35 Watt.
Benchmarks indicate modern demanding games of 2007-2010, such as Crysis, BF2 and Metro 2033 were playable at medium settings smoothly, using a 1024x768 resolution. Therefore, today's modern demanding games should be playable on the medium preset, using a 1024x768 resolution and extremely demanding modern games such as Crysis 3 on the lowest preset.
Its performance is higher than Mobility 5400 GPUs and not far from Mobility HD 5650. However, as based on the Terascale 1 architecture, DirectX 11 games aren't supported.
