In terms of overall gaming performance, the graphical capabilities of the Nvidia GeForce GT 635M v3 are significantly better than the Nvidia GeForce 9800M GT.

The GT 635M was released over three years more recently than the GeForce 9800M GT, and so the GT 635M is likely to have far better driver support, meaning it will be much more optimized and ultimately superior to the GeForce 9800M GT when running the latest games.

The GT 635M has 1536 MB more video memory than the GeForce 9800M GT, so is likely to be much better at displaying game textures at higher resolutions. However, the overall memory performance is about the same.

The GeForce 9800M GT has 22.4 GB/sec greater memory bandwidth than the GT 635M, which means that the memory performance of the GeForce 9800M GT is slightly better than the GT 635M.

The GeForce GT 635M v3 has 144 Shader Processing Units and the GeForce 9800M GT has 96. However, the actual shader performance of the GT 635M is 187 and the actual shader performance of the GeForce 9800M GT is 120. The GT 635M having 67 better shader performance is not particularly notable, as altogether the GeForce 9800M GT performs better when taking into account other relevant data.

The GT 635M transistor size technology is 25 nm (nanometers) smaller than the GeForce 9800M GT. This means that the GT 635M is expected to run slightly cooler and achieve higher clock frequencies than the GeForce 9800M GT.

The GeForce GT 635M v3 requires 35 Watts to run and the GeForce 9800M GT requires 65 Watts. The GeForce 9800M GT requires 30 Watts more than the GT 635M to run. The difference is not significant enough for the GeForce 9800M GT to have a noticeably larger impact on your yearly electricity bills than the GT 635M.

GPU Mini Review

Mini ReviewOverview
GeForce GT 635M v3 is a fast-middle-class Mobile Graphics Card based on the second revision of the Fermi 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.

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 650MHz.

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.

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.

GeForce GT 635M v3 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 v3.
NVIDIA GeForce 9800M GT GPUs deliver optimized performance for immersive gaming on-the-go. Powering the next generation of visual computing, blazing-fast mobile gaming, and the ultimate HD experience with PureVideo HD technology. This product is also enabled for CUDA applications and is NVIDIA PhysX-ready.
