I have only a PCIe 2.0 x4 and a PCIe 3.0 x16 free and I need to install a 10Gbps SFP+ card and a graphic card for transcoding with Jellyfin (the CPU is an old E5-2620 v2). Since I can’t find any SFP+ card that is x4, do you know a graphic card with decent transcoding capabilities (I’d day 2 4K simultaneously) that is only PCIe 2.0 x4?

Edit: the x4 slot is full length.

    PCIe is back- and forwards-compatible, so even an RTX 4090 would in theory work in a PCIe 2.0 x4 slot.

    Now, PCIe 2.0 x4 is obviously really slow compared to what most current cards support (PCIe 4.0 x16), but I doubt transcoding is bandwidth sensitive on the PCIe link.

    So pick pretty much any card, be wary though that some consumer-focused cards artificially limit the amount of concurrent transcoding sessions they support. Seems like Nvidia is limiting consumer cards to now 8 sessions, which is probably plenty.

        There are things you can do in Linux to unlock the max number of transcoding sessions as well. You can Google it if you ever hit that wall.
