DDR5 is better. Max resolution is determined by your graphics card.

ddr5 gives high speed whereas 4gb gives more space ? Can you explain any technicalities for choosing one! Thanx for your time in advance. My requirement is to play games with a min fps of 30, higher or avg fps is not important if i get a min of 30 fps. Please dont recommend any graphics card but help me with the speed and memory factor w.r.t. fps. Also second part of my ques???? Well my monitor has no stamp of 1080p on it so choosing a better graphics card will let me display 1920X1080 resolution? Or should i have a led monitor with full hd sticker?

Max resolution is determined by the lowest common denominator between the graphics card and monitor.

In most cases the monitor is limited to much lower than the graphics card is capable of.

GDDR5 memory is the faster memory, but that is not the only factor.

How about you tell us what laptops you are comparing, then we can help you much easier.

I am having a desktop & want to upgrade my graphics memory by HD 7750. Both varities i mentioned above coming at almost same price so difficulty in choosing. Also again do i have to buy a 1080p sticker led for 1920X1080 resolution or the 7750 will help?
Will it also help with a min of 30fps, again max or avg fps is out of question....

Depending on the specific game an HD7750 can not do min 30 FPS on ALL games at 1080p.

For that resolution you need to be looking at least at the HD7850/R 9 270.

However the GDDR5 versions are ALWAYS better.

The HD7750 is fine for 1366x768 at ABOVE 30FPS.
Its a good choice to get the 1GB GDDR5 version.

Do you want me to explain what minimum, average and maximum FPS mean?

Willl it do good for cod ghost or ac blackflag?
Thanx for your time & what i dont get is fps and their relations with graphics memory (1/4 gb) & speed (ddr3/5)? Why do they build one with 4gb ddr3 if everyone recommends a 1gb ddr5 ?

MARKETING. LOL

They do it to sell stuff.

Anyway. Memory amount is needed for higher resolutions, so the higher the resolution, the more VRAM you need.

GDDR5 is just a faster version of DDR3 RAM that allows for faster memory transfer from GPU to VRAM.

And yes, it will play those games.

So last thing finally, although i have got my answer. Are you sure of games like sleeping dogs, ac 4, cod ghost, nfs rivals, batman, fc3, bf4, etc. do min fps of 30 with 1gb rather than 4gb if i choose ddr5 at 1366X768? Thank You!!!!!
