Gaming Performance Comparison

In terms of overall gaming performance, the graphical capabilities of the AMD Radeon HD 8730M are marginally better than the Nvidia GeForce GT 635M 2GB DDR3.

The 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 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 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 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 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 Radeon HD 8730M and the GeForce GT 635M 2GB DDR3 have the same amount of video memory, but are likely to provide slightly different experiences when displaying game textures at high resolutions.

The GT 635M has 11.2 GB/sec greater memory bandwidth than the Radeon HD 8730M, which means that the memory performance of the GT 635M is slightly better than the Radeon HD 8730M.

The Radeon HD 8730M has 384 Shader Processing Units and the GeForce GT 635M 2GB DDR3 has 144. However, the actual shader performance of the Radeon HD 8730M is 242 and the actual shader performance of the GT 635M is 194. The Radeon HD 8730M having 48 better shader performance is not particularly notable, as altogether the GT 635M performs better when taking into account other relevant data.

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

The GeForce GT 635M 2GB DDR3 requires 35 Watts to run but there is no entry for the Radeon HD 8730M.

GPU Mini Review

Mini ReviewRadeon HD 8730M is a fast-middle-class GFX based on the GCN architecture.
It offers 384 Shader Processing Units, 24 TMUs and 8 ROPs. The central unit can be initially clocked at up to 650MHz reach up to 700MHz in Turbo Mode while the memory interface is of 128-bit of standard DDR3. The frame buffer will range between 1GB and 2GB but both versions will perform exactly the same.
Benchmarks indicate modern demanding games can be played with Medium Settings.
GeForce GT 635M 2GB DDR3 is a middle-class mobile GPU still based on the 2010 Fermi architecture.
It's based on the Fermi GF106 Core and offers 144 Shader Processing Units, 24 TMUs and 24 ROPs on a 192-bit memory interface of 2GB DDR3. The central clock runs at 675MHz and the memory clock operates at 900MHz. Expect a power consumption of up to 35 Watts.
Its performance is above the average and actually higher than the GDDR5 variant thanks to the higher SPUs, TMUs and ROPs count and because extra bandwidth does not benefit this GPU largely and so the GDDR5 is essentially bottlenecked by the GPU's processing power.
Therefore expect to run some modern demanding games at high settings with fluent frame rates (30+) using a 1080p resolution.
