I just switched to 2.8 last week and only got a chance to play around with it. I was excited about the EEVEE renderer as advertised so I tried do a comparison between the two (CYCLES vs EEVEE) but I think I'm doing something wrong in here.

If you notice the EEVEE sample image, it doesn't look anything better or at least the same as the CYCLES image.

Can someone please tell me where i did wrong?

So, there's a lot of things that are going on.

Eevee is a fundamentally different render engine than cycles. And while node-compatibility is kept between the two, lighting in general doesn't transfer as well.

Firstly, Eevee doesn't support emissive materials. Instead it relies on lamps. These lamps don't port over from cycles easily either, you need to adjust their power.

Furthermore Eevee doesn't do transparency out of the box. You'll need to enable that checkbox under "Screenspace Refraction, and then again under the material settings.

The Checkbox in question, in the Materials Tab.

I'm adding this because, judging by the amount of noise in your scene, it's likely that you have a glass pane in that window.

Please provide further details on your lamps and setup if any of this doesn't work.

I can't see in your outliner, so I'm not sure, but if you used a plane with emission material insted of lighting that could be the problem.explanation

Cycles and eevee both have different light values, you'll have to use different values in eevee to match the lighting in cycles, by default the lights are set to 1 if you change from cycles to eevee. For realistic lighting and reflections you will have to enable Screen space reflections, use light probes and bake indirect lighting.

EEVEE is just to see the coloured values in low rendering time, It does not have high level capability to render lights, reflection, etc.
Cycles Rendering comes with some high resolution Rendering or what I can say, like some high quality thing. It renders slow as compared to EEVEE, but there's an exception of High Resolution/Quality Render.
There's one thing added in Blender, called LookDev,when you press Z press Numpad 2 and you are rendering as LookDev.
According to me LookDev has better results than EEVEE if you want faster preview.
