Gaming Performance Comparison
In terms of overall gaming performance, the graphical capabilities of the Nvidia GeForce GT 635M are noticeably better than the Intel HD Graphics 4600 Mobile.
The GeForce GT 635M has a 475 MHz higher core clock speed and 20 more Texture Mapping Units than the Graphics 4600. This results in the GeForce GT 635M providing 15.4 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 GeForce GT 635M has a 475 MHz higher core clock speed and 14 more Render Output Units than the Graphics 4600. This results in the GeForce GT 635M providing 10.4 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 Graphics 4600 was released over a year more recently than the GeForce GT 635M, and so the Graphics 4600 is likely to have better driver support, meaning it will be more optimized for running the latest games.
The GeForce GT 635M has 2048 MB video memory, but the Graphics 4600 does not have an entry, so the two GPUs cannot be reliably compared in this area.
The HD Graphics 4600 Mobile has 20 Shader Processing Units and the GeForce GT 635M has 144. However, the actual shader performance of the Graphics 4600 is 108 and the actual shader performance of the GeForce GT 635M is 194. The GeForce GT 635M having 86 better shader performance and an altogether better performance when taking into account other relevant data means that the GeForce GT 635M delivers a slightly smoother and more efficient experience when processing graphical data than the Graphics 4600.
The Graphics 4600 transistor size technology is 18 nm (nanometers) smaller than the GeForce GT 635M. This means that the Graphics 4600 is expected to run slightly cooler and achieve higher clock frequencies than the GeForce GT 635M.
The HD Graphics 4600 Mobile requires 47 Watts to run and the GeForce GT 635M requires 35 Watts. The Graphics 4600 requires 12 Watts more than the GeForce GT 635M to run. The difference is not significant enough for the Graphics 4600 to have a noticeably larger impact on your yearly electricity bills than the GeForce GT 635M.
|Mini Review||Overview |
Intel HD Graphics 4600 Mobile are Integrated Graphics in some of Intel's Mobile Haswell Processors.
The Haswell GT2 Core includes support for DirectX 11.1, OpenCL 1.2 and OpenGL 4.3. Additionally, it also offers better Decoding Performance, when compared to its Predecessors.
It equips a GPU Codenamed GT2 which offers 20 Shader Processing Units, 4 TMUs and 2 ROPs. The Central Unit Initially Runs at 200MHz and goes up to 1350MHz, in Turbo Mode.
The GPU Shares the System's RAM which varies from System to System. Typically, the GPU reserves 1.7GB. Depending on whether or not the system's RAM is Dual-Channeled, it can access either a 64-bit or 128-bit memory interface. The operating memory clock also depends on which speed the System's RAM is running and is limited by the highest operating speed that the Processor supports. In this case, it is 800MHz.
It is then obvious the Memory Bandwidth depends on a lot of factors and thus this Graphics Card performance may vary heavily from system to system.
The Most Powerful Variant Offers Performance similar to a dedicated GeForce GT 540M.

We recommend 4GB of RAM for a system with Intel HD Graphics 4600 Mobile.
GeForce GT 635M 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 675MHz.
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
With a rated board TDP of 35W, it is suited for 15" or larger laptops.
GeForce GT 635M is essentially a renamed GeForce GT 555M v3.
Gaming benchmarks put its performance identical to a GeForce GT 555M v3.
We recommend a decent processor (Intel Core i5 Mobile) and 4GB of RAM for a system with GeForce GT 635M.
