Sure. But back in the real world that's 7 cycles/byte, DMA doesn't exist, and you have a 320x200 framebuffer with per-scanline palettes, H-INTs and optional RLE mode. No separate sound CPU, but you've got a chip that can play 32 channels of 8-bit samples by DMA. Now show solid-filled rotating polygonal objects with scrollers and music and starfields (and yes, people did).
The CPU wasn't designed for Nintendo, it was designed for Apple and Commodore. Once you understand that, it makes more sense
