GPU Wiki Architecture
Pending — architecture history and specifications still require editorial source review.
RIVA TNT moved NVIDIA into stronger high-performance 3D competition before the TNT2 and GeForce eras.
Vanta LT is the lowest-cost TNT2-era branch, mainly useful for OEM and period-correct value PC documentation.
TNT2 M64 Vanta sits in the low-cost TNT2 branch where names can hide a narrower memory path.
TNT2 Ultra was the high-clock enthusiast member of the TNT2 family before GeForce 256 arrived.
The 16 MB TNT2 M64 Vanta entry tracks a specific low-cost memory configuration inside the TNT2 value branch.
TNT2 M64 kept TNT2 branding but used a narrower memory path aimed at cheaper systems.
RIVA TNT2 was NVIDIA's final major pre-GeForce desktop family, with many full, Ultra, Pro, M64, and Vanta variants.
TNT2 Pro sits between ordinary TNT2 and Ultra, making variant identification important.
