Different bios for the same card?

[mr_oraculus]

Hi everyone!

I'm new here so hopefully I don't screw up the posting etiquette too badly but appreciate your patience as I learn! Well, here it goes...

I picked up some new XFX 6800 XT cards and noticed they came with different bios. One card had the same bios as my previous two cards, and one had a completely different bios. I’ve listed the details on the cards, bios, and my related questions below. Thanks!

Here are the card and their bios:

XFX 6800 XT (3 cards) – 113-5N21XT_200801 bios

• These 3 cards seem to be performing better than the other card
• I noticed that this bios is newer, being built on 05/31/2021 and also shows as an unverified file here on the site
• https://www.techpowerup.com/vgabios/235823/235823

XFX 6800 XT (1 card) – 113-68XB6SSE1-C01 bios

• This card does not perform as well as the other 3
• I noticed this bios is older, being built on 11/11/2020 and shows as a verified file here on the site
• https://www.techpowerup.com/vgabios/230910/xfx-rx6800xt-16384-201114

Here are my questions:

• Why would these card, all purchased as new in box, come with different bios?
• Is it worth flashing the newer bios of the 3 higher performing cards to the card with the older bios that isn’t performing as well?

Thanks for the input!

Yes, different sku. Different batches.

Different memory, cooling tdp...
