Gaming Performance Comparison

In terms of overall gaming performance, the graphical capabilities of the AMD Radeon HD 8750M 2GB DDR3 are noticeably better than the Nvidia GeForce GT 635M 2GB DDR3.

The HD 8750M has a 100 MHz higher core clock speed and the same number of Texture Mapping Units as the GT 635M. This results in the HD 8750M providing 2.4 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 HD 8750M has a 100 MHz higher core clock speed than the GT 635M, but the GT 635M has 8 more Render Output Units than the HD 8750M. As a result, the GT 635M exhibits a 4.6 GPixel/s better Pixel Fill Rate than the HD 8750M. However, both GPUs support DirectX 9 or above, and pixeling performance is only really relevant when comparing older cards.

The HD 8750M was released over a year more recently than the GT 635M, and so the HD 8750M is likely to have better driver support, meaning it will be more optimized for running the latest games.

The Radeon HD 8750M 2GB DDR3 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 HD 8750M, which means that the memory performance of the GT 635M is slightly better than the HD 8750M.

The Radeon HD 8750M 2GB DDR3 has 384 Shader Processing Units and the GeForce GT 635M 2GB DDR3 has 144. However, the actual shader performance of the HD 8750M is 285 and the actual shader performance of the GT 635M is 194. The HD 8750M having 91 better shader performance is not particularly notable, as altogether the GT 635M performs better when taking into account other relevant data.

The HD 8750M transistor size technology is 12 nm (nanometers) smaller than the GT 635M. This means that the HD 8750M is expected to run slightly cooler and achieve higher clock frequencies than the GT 635M.

The GeForce GT 635M 2GB DDR3 requires 35 Watts to run but there is no entry for the HD 8750M.

GPU Mini Review

Mini ReviewRadeon HD 8750M 2GB DDR3 is a fast-middle-class GPU based on the GCN architecture.
It offers 384 Shader Processing Units, 24 TMUs and 8 ROPs. There are two versions available: One with DDR3 and another with GDDR5. This is the DDR3 version. On this version, the central unit can be initially clocked at up to 775MHz reach up to 825MHz in Turbo Mode while the memory interface is of 128-bit of standard DDR3. Compared to the GDDR5 version, it's overclocked but it features less bandwidth needed at higher resolutions and in certain games. Still, overall, both versions should perform similar.
Until benchmarks become available, this GPU's rank is subject to change.
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.
