This is the same crap they (Nvidia and AMD both) pulled when this most recent generation of cards came out.
Easy now, Jensen.
What on earth is RDNA 1.4?
RDNA3 was a learning process for them with regard to MCM packaging and the wins/losses that come from that approach and RDNA4 is supposed to essentially be a bug-fixed and much more optimized version of RDNA3.
RDNA5 is supposed to be six to nine months behind RDNA4 which seems to indicate that RDNA4 is more of a half-generation GPU series, more like a "super" release but targeted toward the midrange or lower cards.
It isn't wishful thinking as much as it's a Twitter/Discord circle-jerk by people that went to the YouTube school of Engineering.
DLSS, FSR, and XeSS's days are numbered.
Microsoft and the Khronos Group are sick of vendors doing proprietary shit and have some smart people working on vendor-independent upscaling.
Edit: before any of you start pounding out an empassioned response to tell me that DLSS is hardware accellerated, whatever DirectX and Vulkan upscaling standards come out of this will allow for optional hardware accelleration either on the GPU or CPU. Nvidia/AMD/Intel can write their drivers so the upscaling tech executes using the same hardware features that they're currently using. That's how it went down with multitexturing, shaders, deferred rendering, and so on.
