What is the difference between HDMI and normal Xbox?

I noticed that the HDMI standard or cost not less. But what is the difference between them?

HDMI XBOX Console XBOX 360 Elite "and is black while the other is" XBOX 360 Arcade and white. The other difference is that Elite includes a 120 GB hard drive and 256 MB of internal memory chip arcade. Beyond these two differences, there is no other difference. The console has been discontinued and that the two normal aforementioned consoles are in production and two of them include an HDMI port.
