Some more interesting things from the QA:
Why only 10 GB of memory for RTX 3080? How was that determined to be a sufficient number, when it is stagnant from the previous generation?
[Justin Walker] We’re constantly analyzing memory requirements of the latest games and regularly review with game developers to understand their memory needs for current and upcoming games. The goal of 3080 is to give you great performance at up to 4k resolution with all the settings maxed out at the best possible price.
In order to do this, you need a very powerful GPU with high speed memory and enough memory to meet the needs of the games. A few examples - if you look at Shadow of the Tomb Raider, Assassin’s Creed Odyssey, Metro Exodus, Wolfenstein Youngblood, Gears of War 5, Borderlands 3 and Red Dead Redemption 2 running on a 3080 at 4k with Max settings (including any applicable high res texture packs) and RTX On, when the game supports it, you get in the range of 60-100fps and use anywhere from 4GB to 6GB of memory.
Extra memory is always nice to have but it would increase the price of the graphics card, so we need to find the right balance.
Does Ampere support HDMI 2.1 with the full 48Gbps bandwidth
[Qi Lin] Yes. The NVIDIA Ampere Architecture supports the highest HDMI 2.1 link rate of 12Gbs/lane across all 4 lanes, and also supports Display Stream Compression (DSC) to be able to power up to 8K, 60Hz in HDR.
tldrdoto – Please clarify if the slide saying RTX 3070 is equal or faster than 2080 Ti is referring to traditional rasterization or DLSS/RT workloads?
Very important if you could clear it up, since no traditional rasterization benchmarks were shown, only RT/DLSS supporting games.
[Justin Walker] We’re talking about both. Games that only support traditional rasterization and games that support RTX (RT+DLSS). You can see this in our launch article here https://www.nvidia.com/en-us/geforce/news/introducing-rtx-30-series-graphics-cards/
Will Nvidia reflex work with pascal GPUs or is this only a Turing/Ampere feature?
[NV_Tim] It will work with 900 series + GPUs, including RTX 20-series.
