That also means the 4070 is about 30% faster than the 3070.īut things can be very dismal for the 3070. According to reviews from Tom's Hardware and Techspot, the 3070 can't quite live up to that ideal however, and only has about 75% of the performance of the 4070 at 1440p and 4K. Given that the 3070 is about 80% of the cost of the 4070, ideally it would also have about 80% of the performance of the 4070, at least so it can be of equal value. As of the time of writing, Twitch doesn't support AV1 encoding, but when it does, it will make AV1 a big ticket feature for the 4070.Ĭonsidering these two cards aren't too different when it comes to design or features, it really comes down to performance. AV1 encoding is even more efficient and better looking than the popular H.264 encoder, and it's already getting important support in streaming apps like OBS and platforms like YouTube. The other feature the 4070 boasts is AV1 encoding, which is even more niche but also potentially a game changer for anyone who streams or records gameplay. Additionally, AI isn't very good at replicating UI elements, particularly text, and you will regularly see weird graphical glitches and flickers in the UI. Instead of showing you the newest frame immediately, it has to be held back so the AI can show you one of its frames first, and that imposes a severe latency penalty, which is going to feel very weird when combined with a high framerate since high framerates usually mean low latency.
But here's the catch: AI-made frames need to be inserted between two already rendered frames, and the AI also needs to duplicate UI elements.
