5600XT: 12Gbps vs 14Gbps


Near the beginning of US lockdown, I bought a new XFX RX 5600XT THICC II (aka the capslock card).


I noticed that the specific listing I bought is now out of stock, and the replacement part is touting 14Gbps memory speeds (vs my 12). I have until the end of the month to return/exchange it, and I can fall back on my old card in the mean time. Couple questions:

  1. Does it make that much of a difference?
  2. Is it worth exchanging for the upgraded card? (they're the same price, last I checked)
  3. What effect was the launch 5600XT VBIOS supposed to have? Would that bring my card to 14Gbps? (I haven't updated my VBIOS yet)


GPU-Z for reference...

1. Yes


2. Depends, you could always claw back some performance difference by overclocking the current card


3. More power limit, more factory overclock and more stock memory speed. Just the BIOS alone does not bring 14Gbps rated memory (obviously)
