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.
