Yeah, not only the huge required jump in raw fill rate, but to get the most out of a 4K TV you need higher detail models and textures and that means you also need a huge jump in VRAM, which never materialised.

The frame buffers/render targets alone for 8K are massive.

Basically 400MB for 12 bytes/pixel (64bit HDR RGBA + 32bit depth/stencil)

vs the 64000 bytes that Doom had to fill...
