RDNA3 cards also have AV1 encode. RDNA 2 only has decode.
With the bitrate set to 100MB/s it happily encodes 2160p or even 3240p, the maximum resolution available when using Virtual Super Resolution (which renders at >native res and downsamples, is awesome for titles without resolution scaling when you don't want to use TAA)
Right. That’s 223642 kilobits/s (kbps) in your picture or ~200MBit/s whereas you wrote (intentionally or otherwise) 200Mbyte/s a nearly 10 fold difference (100Mbit/s =~ 12Mbyte/s). 100MByte/s is 800Mbit/s or ~800000 kbps which is an order of magnitude more insanity than already choosing 100Mbit/s for live streaming (and not physically possible on consumer GPUs I believe).
