Yes, the tiled-based architecture of their "GPU" is undeniably less performant. Even comparing to lesser GPUs.

- zeusk 3y agoNvidia is tile based since Maxwell
- spookie 3y agoYes, I should've been more specific. Mobile GPUs often employed in ARM architectures often use a technique called "Tile-Based Deferred Rendering" (TBDR). This involves not just splitting the frame into tiles but also delaying the actual shading operations. This two-step approach minimizes overdraw but can create bottlenecks in scenes with intricate geometry or advanced lighting, shadows, and reflections. Nvidia's approach doesn't have this.
- wtallis 3y agoHow is the deferred rendering in TBDR different from the deferred shading and deferred lighting that have almost completely supplanted forward rendering in commercial games and engines?
- cztomsik 3y agoWhy exactly is tile-based a bad idea? Most rendering engines are tile-aware already.
