In terms of overall gaming performance, the graphical capabilities of the AMD Radeon HD 8730M are very slightly better than the Nvidia GeForce GT 635M.

The GeForce GT 635M has a 25 MHz higher core clock speed and the same number of Texture Mapping Units as the Radeon HD 8730M. This results in the GeForce GT 635M providing 0.6 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 GT 635M has a 25 MHz higher core clock speed and 8 more Render Output Units than the Radeon HD 8730M. This results in the GeForce GT 635M providing 5.6 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 Radeon HD 8730M was released over a year more recently than the GeForce GT 635M, and so the Radeon HD 8730M is likely to have better driver support, meaning it will be more optimized for running the latest games.

The GeForce GT 635M has 1024 MB more video memory than the Radeon HD 8730M, so is likely to be much better at displaying game textures at higher resolutions. However, overall, the Radeon HD 8730M has superior memory performance.

The Radeon HD 8730M has 3.2 GB/sec greater memory bandwidth than the GeForce GT 635M, which means that the memory performance of the Radeon HD 8730M is marginally better than the GeForce GT 635M.

The Radeon HD 8730M has 384 Shader Processing Units and the GeForce GT 635M has 144. However, the actual shader performance of the Radeon HD 8730M is 228 and the actual shader performance of the GeForce GT 635M is 194. The Radeon HD 8730M having 34 better shader performance and an altogether better performance when taking into account other relevant data means that the Radeon HD 8730M delivers a marginally smoother and more efficient experience when processing graphical data than the GeForce GT 635M.

The Radeon HD 8730M transistor size technology is 12 nm (nanometers) smaller than the GeForce GT 635M. This means that the Radeon HD 8730M is expected to run slightly cooler and achieve higher clock frequencies than the GeForce GT 635M. As they exhibit similar graphical performance, the Radeon HD 8730M should consume less power than the GeForce GT 635M.

The Radeon HD 8730M requires 15 Watts to run and the GeForce GT 635M requires 35 Watts. The GeForce GT 635M requires 20 Watts more than the Radeon HD 8730M to run. The difference is not significant enough for the GeForce GT 635M to have a noticeably larger impact on your yearly electricity bills than the Radeon HD 8730M.

GPU Mini Review

Mini ReviewOverview
Radeon HD 8730M is a Fast-Middle-Class Mobile Graphics Card based on the Second Revision of the GCN Architecture.

Architecture
The GCN 1.1 Release adds support for AMD's TrueAudio Technology which does calculations of audio effects "better" than the CPU and further improves the Powertune Technology.

GPU
It equips a GPU codenamed Mars PRO which has 6 Compute Units activated and thus offers 384 Shader Processing Units, 24 TMUs and 8 ROPs. The Central Unit Initially Operates at 650MHz and goes up to 700MHz, in Turbo Mode.

Memory
The GPU accesses a 1GB frame buffer of DDR3, through a 128-bit memory interface. The size of the frame buffer is adequate. The memory clock operates at 1000MHz.

Features
DirectX 11.0 Support (11.0 Hardware Default) and support for Crossfire, PowerTune Technology, Eyefinity, App Acceleration, HD3D, ZeroCore Power and other technologies.

Power Consumption
With a rated board TDP of 15W, it is suited for 13" or larger laptops.

Performance
Gaming benchmarks put its performance somewhat above NVIDIA's GeForce GT 635M.

System Suggestions
We recommend a Decent Processor (Intel Core i5 Mobile) and 8GB of RAM for a system with Radeon HD 8730M.
Overview
GeForce GT 635M is a fast-middle-class Mobile Graphics Card based on the second revision of the Fermi Architecture.

Architecture
The Fermi Architecture is manufactured with a 40nm technology and uses a technique known as Hot Clocking: The Shaders are clocked twice as fast as the Central Unit. While this leads to a reasonable performance boost, it causes enormous amounts of energy dissipation, leading, ultimately, to a significantly higher operating temperature.
Fermi is also the first GPU architecture with fully cached memory access which increases memory performance.

GPU
It equips a GPU Codenamed GF116 which has 3 Stream Multiprocessors activated and thus offers 144 Shader Processing Units, 24 TMUs and 16 ROPs. The Central Unit is clocked at 675MHz.

Memory
The GPU accesses a 2GB frame buffer of DDR3, through a 128-bit memory interface. The size of the frame buffer is exaggerated and in no way benefits the GPU. The Memory Clock Operates at 900MHz.

Features
DirectX 11.0 Support (11.0 Hardware Default) and support for Optimus, 3D Vision Surround, PhysX, Realtime Raytracing and other technologies

Power Consumption
With a rated board TDP of 35W, it is suited for 15" or larger laptops.

Performance
GeForce GT 635M is essentially a renamed GeForce GT 555M v3.
Gaming benchmarks put its performance identical to a GeForce GT 555M v3.

System Suggestions
We recommend a decent processor (Intel Core i5 Mobile) and 4GB of RAM for a system with GeForce GT 635M.
