Can you Overclock an RX 570 4GB to match an RX 580 8GB?

[DanielMDA]

Ok, so I was making a build for a Guy with the PowerColor Red Devil RX 580 8GB, this guy was aiming at 1080p75FPS (for 2-3 years), I was finishing the build. A $700 build to be precise, but before my guy finished looking up for parts, he told me that a guy told him that he could get the performance of the RX 580 8GB (or even surpass it) with an RX 570 4GB (PowerColor RedDevil). I personally believe that you wont get the same performance of a 4GB RX 570 compared to an 8GB RX 580, since it has more CU´s (Compute Units), Higher Clocks (+150MHz) and a higher bus bandwidth and twice the VRAM.

 

Is the RX 580 8GB the Polaris King or can it´s younger, smaller brother (in a 4GB Edition) match it or surpass it?

 

But what do you think?

 

Vote on the Poll or comment below... or do both if you want.

 

EDIT: Please vote, I would like to know what you think.

My guy eventually went with the 8GB RX 580 because of the future-proofness.

You can overclock it to match a stock 580. But then you could overclock the 580 beyond that, so the performance gap remains.

 

VRAM does not really factor into this.

In some games it does, besides the guy is aiming to get 1080p80FPS for 2-3 years. (PUBG, Witcher, AC Origins, Wolfenstein 2)

You can get that frame rate for a hell of a long time with either card. Just lower the settings.

Obviously Ultra...

It's not obvious, and frankly Ultra isn't really worth the performance hit in most cases anyway.

Hey I thought OCing the RX 500 series was preety much unviable, since you know, its usually near its maximum, is there really enough headroom to match a 570 to a 580?

Hey is it worth OCing the Memory Clock from an RX 580 8GB from 8GBPS to 9GBPS (like Nvidia does to some 1060 6GBs?)
