Do they make adapters from agp to pcie?
Well, Albatron did once, the ATOP:
https://cdrinfo.com/d7/content/albatron-unvei … ics-card-bridge
It used the nVidia HSI AGP - PCIe bridge chip and was almost complete vaporware in 2005. It was shown physically - but not working - at Computex Taipei 2005; all known photographs of it come from that one trade show. Also compatibility was limited - it supposedly only worked with a limited number of nVidia GPUs from the GeForce 4, FX and 6-series.
Of course, there is another way:
1) use an AGP to PCI adapter (like this) to put your AGP card into a PCI slot
2) use a PCI to PCIe adapter (available on AliExpress for less than EUR 20 and free shipping)
Downsides: *if* it works you get max 133MB/s (32b PCI 33MHz) bandwidth, which will totally bottleneck a high-end AGP GPU. Oh, and the AGP to PCI solution is 3.3V, so the cards needs to work with that, i.e. be universally keyed, so not AGP 3.0 / 8x
I thought modern motherboards would have a legacy setting that would allow older cards to be used. (Also I know this post is completely pointless and just wanted a laugh 🤣)
There is such a thing as CSM legacy compatibility mode in UEFI, but it was considered end-of-life a few years back. Maybe it will still work on a Zen 5 platform board, but I wouldn't assume it, AMD has been strongly recommending UEFI-only for some time now.
I have the PCI to PCIe adapter and a friend has asked me to build him a new computer. Actually I advised him not to (he literally only uses it for web browsing and office work, only reason for upgrade is overload of crapware on his Windows 10 install that's complaining about end of support and the non-TPM 2.0 system not supporting Windows 11, so a new SSD and a reinstall on that with Win11 using Rufus should solve his problems), but if he insists, I might get a Zen 5 and try this out with a PCI VGA card. If...
