The GPU space isn't the Nintendo ecosystem though, you can use the same argument in favor (or against) Apple's walled garden. Outside of CUDA they aren't offering really anything distinguishing in the consumer space. Eventually it is all about performance & if/when AMD takes the performance crown back Nvidia will have to lower its prices, as they did a decade back, that's just a fact given the market is also shrinking. If they don't then their results will take an even bigger hit than what we saw earlier in the year. But the point about mindshare could still apply ~ someone will need to beat them at the top end, even if just for traditional PC (non RT) games.
The problem is that the old graphics performance measurements are steadily losing their ability to capture a graphics card's full functionality.
We're seeing that in longer and longer graphics card reviews that now have to confront ray tracing performance as well as image upscaling technology performance (FSR, DLSS 2, DLSS 3+Frame Injection, XeSS). More and more gaming titles are including RT and upscaling technologies.
You can measure cards by pure rasterization performance but if a title has RT and DLSS support, it's more likely that the user is going to turn on those features. I'd be stupid to play
Control on my Ampere cards without RT and DLSS turned on. Even if
Shadow of the Tomb Raider's ray tracing implementation is barebones, the DLSS certainly gives an uplift.
If AMD is to retake the performance crown from NVIDIA, they will also have to do it with RT and ML cores. That specialized silicon is being used more frequently with each passing week.
Look at the iPhone and iPad. Apple has gone heavy on ML cores (they call it Neural Engine) and they are doing all sorts of things with machine learning that Geekbench don't measure. It's like Samsung claiming to be the performance champion because their Geekbench score is higher than the iPhone 14.
Joe Consumer doesn't run benchmarks. He uses the device in a variety of situations and more frequently some of those usage cases include taking advantage of differentiated and specialized silicon whether it be using hardware video codecs, image reconstruction, text recognition, etc.
The graphics card industry really needs to come up with newer metrics and measuring tools to capture these newer technology developments. The days of using 3D raster results as the yardstick for GPU performance are waning.
Mindshare is important. NVIDIA has established itself as the brand with superior performance.
For AMD to topple NVIDIA off of their perch, AMD would likely have to beat NVIDIA by a substantial margin (like 25%) across the board for a couple of GPU generations before the public perception changes on a wide scale.
