They have to report it because it's misleading to investors if Nvidia gaming sales double/triple/whatever and a huge chunk of that is not gaming, it's mining -- which is short term and Nvidia knows it's mining, which is the crux of the issue here (that nvidia knew internally that these cards were being used for mining but didn't disclose it). This is because investors think "oh gaming is doing really good and is much bigger than we previously thought, let's invest on this sector that's relatively stable and showing growth" when it could have been "well a huge chunk of these sales are being used for mining, and that's very volatile and could randomly go belly up, let's not invest" had Nvidia disclosed it. CMP wasn't released at the time. I know they had weird specific cards throughout 2018 they released, P106's for example with no displays but idk if that was from Nvidia or partners just trying to cash in but this was from 2017-2018. There's also been articles released about this lawsuit that claims Nvidia has done a better job of tracking these sales through partners themselves.. which makes me think they didn't have a good grasp on it in 2017 anyway. I think the number of people doing professional work on gaming cards is miniscule compared to the sales to miners during these mining booms - also it's a pretty consistent number... it's not like from one generation to a next the number of people using gaming cards to do professional work suddenly doubles or triple sales.
