Is there any place to get the graphical benchmarks of Intel processor internal graphic part only?

Hello I've been shopping for use notebook on eBay and my major concern has been the graphical capabilities of these notebooks. I'm looking for one which will let you externally Attach your computer monitor or television and display videos the parameters of which I will post below in all this splendor. There are old laptops available which have Nvidia processor modules for graphics and once which only use internal processor graphics. What I am trying to figure out is if a third-generation I5 internal processor graphic laptop only can be as good as a first-generation I5 laptop with a Nvidia processor module.

I also I'm trying to figure out if either could be as good or better than my present desktop setup which is dual core Intel processor E5200 running at 2500 Hz with the video card NVIDIA GT 520 . I can find benchmarks for my E5200 processor and my NVIDIA GT 520 card, but does far cannot judge how these benchmarks will compare with the benchmarks of the laptops am looking for because I do not have an available source of benchmarks for the graphical portion of processor included graphics.

Two examples of video I am trying to render as good as my present desktop setup are below.
