Smaller GPU memory bits is faster gpu ?

[TheDoel]

Hello

I was wondering why today GPU have a smaller bits rather than back then. Back then people use to say that bigger bits is better card and some people still insist that bigger bits is still the better one. 

Is there a better explanation for that ? 

 

Thank you and sorry for bad language

The size of the transistors shrunked, so chips could hold more at the same size.

You need to understand the context

When you say old, is how old, and what is your comparison?

Faster RAM doesn't always equate faster GPU.

altough faster ram do affect GPU performances.

Most comparison is usually AMD vs nVidia which is really not accurate at all

 

it's a bit hard to do comparison by todays standard GPU since most GPU are using GDDR5 and 128-bit or bigger)

The only relevant topic is the newest GT 1030 which the older version are using 64-bit GDDR5 while there are new version using DDR4 which is slower, on older model like GT 730 not only there are 2 variant of Memory, there's also different chipset (Fermi based vs kepler based)

With AMD Hardware mostly their GPU lineup using HBM will always be superior than using GDDR5, on older models obviously the one using GDDR5 will always better than using DDR3 even with same bus speed.

I see 

It's so weird here in my place some people still comparing bits (like GTX 550Ti vs GTX 750 Ti)

What do you mean by bits? You mean GB, GigaBytes?

no, it was like Nvidia GeForce GTX 960 2GB "128bit"

That's the memory bus. Whatever the GPU has built in is sufficient for the rest of it. It's just the width of the memory bus, which determines how much data can be transferred at once. On lower end graphics cards, the GPU will have a smaller memory bus, and this is usually fine for the card.
