In terms of overall gaming performance, the graphical capabilities of the Nvidia GeForce GT 620M are very slightly better than the Intel HD Graphics 4000 Mobile.
The Graphics 4000 has a 25 MHz higher core clock speed than the GeForce GT 620M, but the GeForce GT 620M has 12 more Texture Mapping Units than the Graphics 4000. As a result, the GeForce GT 620M exhibits a 7.4 GTexel/s better Texture Fill Rate than the Graphics 4000. This still holds weight but shader performance is generally more relevant, particularly since both of these GPUs support at least DirectX 10.
The Graphics 4000 has a 25 MHz higher core clock speed than the GeForce GT 620M, but the GeForce GT 620M has 4 more Render Output Units than the Graphics 4000. As a result, the GeForce GT 620M exhibits a 2.4 GPixel/s better Pixel Fill Rate than the Graphics 4000. However, both GPUs support DirectX 9 or above, and pixeling performance is only really relevant when comparing older cards.
The GeForce GT 620M was released less than a year after the Graphics 4000, and so they are likely to have similar driver support for optimizing performance when running the latest games.
The GeForce GT 620M has 1024 MB video memory, but the Graphics 4000 does not have an entry, so the two GPUs cannot be reliably compared in this area.
The HD Graphics 4000 Mobile has 16 Shader Processing Units and the GeForce GT 620M has 96. However, the actual shader performance of the Graphics 4000 is 86 and the actual shader performance of the GeForce GT 620M is 120. The GeForce GT 620M having 34 better shader performance is not particularly notable, as altogether the Graphics 4000 performs better when taking into account other relevant data.
The Graphics 4000 transistor size technology is 6 nm (nanometers) smaller than the GeForce GT 620M. This means that the Graphics 4000 is expected to run very slightly cooler and achieve higher clock frequencies than the GeForce GT 620M. While they exhibit similar graphical performance, the Graphics 4000 should consume less power than the GeForce GT 620M.
The HD Graphics 4000 Mobile requires 55 Watts to run and the GeForce GT 620M requires 15 Watts. The Graphics 4000 requires 40 Watts more than the GeForce GT 620M to run. The difference is significant enough that the Graphics 4000 may have a slight adverse affect on your yearly electricity bills in comparison to the GeForce GT 620M.

|Mini Review||Overview |
Intel HD Graphics 4000 Mobile are Integrated Graphics in some of Intel's Mobile Ivy Bridge Processors.
The Ivy Bridge GT2 Core includes support for DirectX 11, OpenCL 1.2 and OpenGL 4.0. Additionally, it also offers Hardware Tessellation, Dedicated L3 Cache and better Video Decoding Performance, when compared to its Predecessor.
It equips a GPU Codenamed GT2 which offers 16 Shader Processing Units, 4 TMUs and 4 ROPs. The Central Unit Initially Runs at 650MHz 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 425M.

We recommend 4GB of RAM for a system with Intel HD Graphics 4000 Mobile.
GeForce GT 620M is a entry-level 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 GF117 which has 2 Stream Multiprocessors activated and thus offers 96 Shader Processing Units, 16 TMUs and 8 ROPs. The Central Unit is clocked at 625MHz. Additionally, GF117 is built using a 28nm technology.
The GPU accesses a 1GB frame buffer of DDR3, through a 64-bit memory interface. The size of the frame buffer is exaggerated and 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 15W, it is suited for small laptops.
Of all the GeForce GT 620M variants, this one is the slowest but also the one that consumes less energy and heats less, as it is built using a 28nm technology.
Gaming benchmarks indicate its performance is slightly below the older GeForce GT 525M.
We recommend a modest processor (Intel Core i3 Mobile) and 4GB of RAM for a system with GeForce GT 620M.
