so what does my laptop need to be faster ? 

Bear in mind rendering is mainly CPU intensive - the faster your CPU the quicker videos will render - your RAM and GPU don't have too much to do with rendering.
My example:
I create projects on my MacBook which is:
2.9GHz Dual Core i7
16GB RAM
512GB SSD
HD4000 GPU (512MB)
I render and upload the project on my Mac Mini Server:
2.6GHz Quad Core i7
8GB RAM
2x1TB HDD
HD4000 GPU (512MB)
Even though I have less RAM and slower drives in my server, it renders a LOT quicker - almost half the time since I have a quad core CPU rather then using the dual core CPU in my MacBook.
Rendering a 10min video (final 2.5GB file, full 1080p) on my MacBook may take 30-45 mins or so.
The same on my Server - lower specs but faster CPU because of the 2 extra cores - takes around 15-18 mins!
When rendering, always go for the fastest CPU.
