Question Is using "Infinity Cache" for Navi 2X a good move?

AMD's previous flirting with exotic memory has been a disaster thanks to high prices and limited availability (think HBM2 in Vega and HBM in Fiji).

With Navi 2X using plain old GDDR6, AMD can get it from anywhere and inexpensively.

NVIDIA is stuck with getting relative expensive GDDR6X memory from Micron.

On the other hand, Infinity Cache has likely ballooned the size of the die and TSMC's 7nm is capacity constraint.

Infinity Cache is going to be the way forward for AMD's APUs to really shore up the bottom end of the market in a big way and pull away from Intel's offerings.
Not really, unless they use alternative technologies such as eDRAM.

SRAM scaling has been slowing down few processes ago. The 5nm TSMC process only affords 20% SRAM reduction in the Apple A14 SoC. SRAM is now trending worse than logic in terms of density.

Discrete GPUs will always be faster and needed because it has the same limitation. What faster iGPUs allow you to do is reach greater masses to be able to play games.

The increase in performance with iGPUs haven't been free either. We went from a CPU-independent iGPU costing $5 to end users to needing a CPU upgrade and costing $30, and maybe even a fast RAM to get the full benefits.

Also we went from playing at 1024x768 resolutions with no AA/AF at 60 fps to 4K resolutions at 60 fps with AA/AF, or 1440p resolutions at 100Hz, and 144HZ or even 200Hz for 1080p resolutions.

Though I never had beyond a 1080p monitor, and currently I'm using one with 1280x1024 resolution, I have seen GTA V running on a 1440p monitor and it looked gorgeous. I can see why if you are willing to spend money you'll go for 1440p or higher resolutions.
