1440p 128bit vs 256bit

[xFluing]

Recently I started gaming in 1440p and it looks amazing, can't wait for 4k to become mainstream, anyway

 

I was wondering if having a 256-bit bus is necessary for gaming at such a resolution (not talking about modern titles here, talking about pre-2014 games), I found out my HD7850 has no trouble playing these games in 1440p, and I think it's thanks to its 256-bit bus, anyway could I still theoretically play those same games in 1440p even with a 128-bit bus on, say, an RX 560 or GTX 1050 or something?

bus width doesn't really matter.

 

Look up reviews of the card at t resolution with the settings you want.

 

You can probalby play older games on those gpu's just fine.

The performance matters, bus-width is not nearly as important.

Depens on what games you play and how demanding they are. I can play Rocket League with GTX 1050 2GB at 1440p at 144-165FPS on LOW no problem. But it struggles a lot with a game like BF1 even on LOW.

Well yeah, as I said, I mostly play pre-2014 games, and currently the 7850 handles them 1440p no problem, I was only worried that going forward, to a stronger card, but narrower memory bus would have an impact on my performance, because the memory bus is not as wide and could probably not carry all the info to properly render 1440p.

It's kinda hard to find benchmarks for a specific graphics preset, since most of them are run at ultra, I can think of guys like RandomGamingInHD, or F2F that would run games at reasonable settings, but chances are they won't have a certain card I want to be looking at.

The bus may be narrow, but its clocked higher and there are better compressions, so it won't make a difference.

 

The 560 will be about the same as you current 7850, so why upgrade?

I'm just saying, in case something happens to this card, it is 6 years old now, and I just had another 7850 break on me last week, good thing the guy agreed to replace it.

There's other factors, such as memory clock speed, that affect memory bandwidth.
