In terms of overall gaming performance, the graphical capabilities of the Nvidia GeForce GTX 660 Zotac AMP Edition are massively better than the Nvidia GeForce GT 635 (OEM).

The GTX 660 has a 79 MHz higher core clock speed and 64 more Texture Mapping Units than the GT 635. This results in the GTX 660 providing 68.2 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 GTX 660 has a 79 MHz higher core clock speed and 16 more Render Output Units than the GT 635. This results in the GTX 660 providing 17.4 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 GT 635 was released over a year more recently than the GTX 660, and so the GT 635 is likely to have better driver support, meaning it will be more optimized for running the latest games when compared to the GTX 660.

The GeForce GT 635 (OEM) and the GeForce GTX 660 Zotac AMP Edition have the same amount of video memory, but are likely to provide slightly different experiences when displaying game textures at high resolutions.

The GTX 660 has 142.6 GB/sec greater memory bandwidth than the GT 635, which means that the memory performance of the GTX 660 is massively better than the GT 635.

The GeForce GT 635 (OEM) has 384 Shader Processing Units and the GeForce GTX 660 Zotac AMP Edition has 960. However, the actual shader performance of the GT 635 is 371 and the actual shader performance of the GTX 660 is 1067. The GTX 660 having 696 better shader performance and an altogether better performance when taking into account other relevant data means that the GTX 660 delivers a massively smoother and more efficient experience when processing graphical data than the GT 635.

The GeForce GT 635 (OEM) requires 35 Watts to run but there is no entry for the GeForce GTX 660 Zotac AMP Edition. We would recommend a PSU with at least 350 Watts for the GT 635.

GPU Mini Review

Mini ReviewOverview
GeForce GT 630 v3 is Middle-Class Graphics Card based on the second revision of the Kepler Architecture.

Architecture
This Graphics Card Equips the Kepler GK208 GPU which is essentially a power optimized version of the GK107 GPU. Whereas it still has a count of 2 Stream Multiprocessors, the bus-width has been cut in half to allow for even a smaller power consumption and consequently a cooler operating temperature.
Additionally, the GK208 GPU allows the Central Unit to reach a significant higher frequency, thanks to the Kepler Boost 2.0 Technology. The better the laptop's cooling system, the higher the frequency.

GPU
It equips a GPU codenamed Kepler GK208-301-A1 which has 2 Stream Multiprocessors activated and thus offers 384 Shader Processing Units, 16 TMUs and 8 ROPs. The Central Unit is clocked at 967MHz.

Memory
The GPU accesses a 2GB frame buffer of DDR3, through a 64-bit memory interface. The size of the frame buffer is exaggerated and in no way benefits the GPU. The Memory Clock Operates at 1001MHz.

Features
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 35W, it requires at least a 350W PSU and it relies entirely on the PCI Slot for power, meaning no extra connectors are required.

Performance
GeForce GT 630 v3 is the fastest of all GeForce GT 630 variants, at the lowest resolutions. As the resolutions increases, its performance decreases significantly.
GeForce GT 635 (OEM) is essentially a fast GeForce GT 630 v2.
Gaming benchmarks put its performance somewhat above GeForce GT 630 v2.

System Suggestions
We recommend a Modest Processor (Intel Core i3) and 4GB of RAM for a system with GeForce GT 635 (OEM).
GeForce GTX 660 Zotac AMP Edition a special edition of GeForce GTX 660.
The new features include a new cooling system and in terms of overclocking, the base-clock was increased from 980MHz to 1046MHz and the boost clock can now reach 1111MHz, instead of 1033MHz. The memory clock was raised to 1652MHz.
Benchmarks indicate a 5.5% performance when compared to the reference card.
