This question already has an answer here:

I plan to buy an Asus Sabertooth Z97 Mark 1 board, with an Intel Xeon Processor E3-1220 v3 (without graphic). Now I don't know if the Asus board uses an integrated graphics or the graphics from my CPU, in the comp-list the CPU is listed, but there is no info about the graphics.

Can anyone explain the iGPU and integrated graphics difference? This is a block diagram of the Z97 chipset, I can't find integrated graphics.

    Essentially its identical to this question Essentially the GPU is on the cpu die in most core i3/5/7 mainstream processors, and the equivilent xeons do not have onboard graphics. You need on die graphics in the cpu you select for the 'integral' ports to work. Else you need a discrete, pci-e gpu – Journeyman Geek Aug 28 '14 at 13:17

iGPU stands for Integrated Graphics Processing Unit.


An integrated graphics processing unit (GPU) doesn't use its own RAM; it utilizes the system's memory instead.


A dedicated, or discrete, GPU has its own independent source of video memory, leaving the RAM your system uses untouched.

According to the asus sabertooth z97 mark 1 specs, it does have an Integrated Graphics Processing Unit:

enter image description here enter image description here

The CPU, working in conjunction with software applications, sends information about the image to the graphics card or Integrated Graphics Processing Unit. The graphics card/Integrated Graphics Processing Unit then decides how to use the pixels on the screen to create the image. It then sends that information to the monitor through a cable. ­

So with that motherboard and CPU, if you were to plug a monitor into the HDMI port it would work/function as expected.

  • but in the block diagram is shown that the chipset use the CPU integrated Graphic. So the most CPUs that can be used in the Z97 chipset has a integrated Graphic but this one not. The remark in the comp-list mean that is a Server CPU and some integrated features not available? – kockiren Aug 28 '14 at 13:11
  • Now I'am confused, it is right that I need a Videocard or not? – kockiren Aug 30 '14 at 8:40

    @kockiren , simply say, yes, you need a video card for the Z97 motherboards. You can simply assume Z97 boards has no display functions (they are having only the ports). So you either go with a CPU with GPU, or display cards. – midnite Sep 10 '14 at 4:16
