Wich RX 570 is the best between these 2

[jelardz2000]

Im nearing to buy an RX 570 and I'm confused on what to buy
More vram with less clock speeds
Or more clock speeds with 4gb vram
These 2 cards
Sapphire pulse 8gb RX 570
4gb powercolor red devil RX 570

Which is faster? And best value wich is worth getting over the other?

Any help will be appreciated thank you in advance


Oh and I can't opt for an RX 580
My budget is super stretched out 570 is the only thing I can afford that

I would buy the 8GB, you can always overclock it a bit to match the other.
