Gaming Performance Comparison
In terms of overall gaming performance, the graphical capabilities of the Nvidia GeForce GT 620M are marginally better than the Intel HD Graphics 4000 Mobile.
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 51 and the actual shader performance of the GeForce GT 620M is 91. The GeForce GT 620M having 40 better shader performance and an altogether better performance when taking into account other relevant data means that the GeForce GT 620M delivers a marginally smoother and more efficient experience when processing graphical data than the Graphics 4000.
The GeForce GT 620M requires 15 Watts to run but there is no entry for the Graphics 4000.

|Mini Review||Intel HD Graphics 4000 Mobile are the successors of Intel HD Graphics 3000 Mobile. |
They come embedded on the new Intel Ivy Bridge CPUS and the new features include DirectX 11 support, Shader Version of 5.0 and openGL Version of up to 4.0.
Benchmarks show that some modern games like Mass Effect 3 and Fifa 12 run smoothly at high settings while modern+demanding games like Anno 2070 and COD: MW3 can still be played at medium settings fluently. However, Very Demanding games like Metro 2033 and Risen 2 require very reduced settings and might not appeal to most casual gamers.
Ultimately, the performance depends on whether or not the system's memory is dual-channel, at which speed it runs and also on the CPU it's embedded since the max core-clock varies from CPU to CPU.
Note 1: We will be adding each individual Intel HD 4000 that comes with each CPU in the future. The performance depends a lot on the CPU its embedded as the clock frequencies and other factors variate according to the CPU itself.
|GeForce GT 620M is an entry-level mobile GFX that has two variants: one based on the 40nm Fermi GF108 Core and another based on the 28nm Fermi GF117 Core. |
This is the GF108 Core based version which offers 96 Shader Processing Units, 16 TMUs and 4 ROPs on a 128-bit memory interface of DDR3. The central clock runs at 475MHz and the memory clock operates at 900MHz. Expect a power consumption of up to 15 Watts.
Benchmarks indicate most modern games will run fluently at medium or low settings while extremely demanding games such as Metro 2033, require very reduced settings to achieve fluent frame rates.
