There is little value in making sub $150 Discrete Graphics, there are no margins in them, The PCB and all its components, the Heat Sync, the Fans. Nvidia only do it to keep high OEM market presence.
Both AMD and Intel are moving to on Chip Graphics and memory, AMD's 5nm APU's 'Ryzen 5000 series' are slated to have RDNA2 integrated graphics with onboard HBM, Intel already have a facsimile of that with Integrated Radeon graphics but they are large and expensive, its the cost effectiveness of them that's been holding that idea back so far but AMD at least are getting a stage where its completely viable with the size and efficiency of RDNA 2, smaller, more efficient console style APU's.
Nvidia's long tern problems remains the lack of X86 and AMD64.
