Criteria for selecting a video card.
get the specs … straight from the manufacturers web site, wiki, or google on the internet. Many extinct cards may also be listed on ebay.
How many and which connectors does the card have. It appears that the 7570 has a Display Port and DVI port. Yes there are DP to HDMI adapters but HDMI now supports sound. The adapter may not.
If you can compare the GPU processor model without disassembling the card do so.
The cards video memory type/model/size should be compared. HBM2, or VDDR5 and others have different transfer rates. For instance the Nvidia SUPER series uses faster memory than the same version that is not SUPER. The RADEON VII uses fast HBM2 memory.
Eventually, you will learn to source this information. Youtube videos will explain the different makes/models of the newer cards but the older stuff is still on the channel.
