Gaming Performance Comparison
In terms of overall gaming performance, the graphical capabilities of the Nvidia GeForce GT 720M are significantly better than the Intel HD Graphics 4000 Mobile.
The GeForce GT 720M was released over a year more recently than the Graphics 4000, and so the GeForce GT 720M is likely to have better driver support, meaning it will be more optimized for running the latest games.
The GeForce GT 720M 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 GeForce GT 720M has 96 Shader Processing Units and the HD Graphics 4000 Mobile has 16. However, the actual shader performance of the GeForce GT 720M is 192 and the actual shader performance of the Graphics 4000 is 78.4. The GeForce GT 720M having 113.6 better shader performance and an altogether better performance when taking into account other relevant data means that the GeForce GT 720M delivers a marginally smoother and more efficient experience when processing graphical data than the Graphics 4000.

|Mini Review||GeForce GT 720M is an entry-level GFX still based on the Fermi architecture. |
It's based on the Fermi GF117 Core, which is manufactured with a 28nm technology, does comes optimized for lower power consumption and is expect to produce less heat and offers 96 Shader Processing Units, 16 TMUs and 8 ROPs, on a 64-bit memory interface of DDR3. The central unit runs at 938MHz and the memory clock operates at 900MHz.
Its performance lies, therefore, somewhere between GeForce GT 625M and GeForce GT 630M. In smaller resolutions, it should perform considerably better but the 64-bit bus width will become a bottleneck for superior resolutions (720p+).
|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.
