Overview

Riva TNT2 M64 Vanta-16 is a configuration-level entry for the value TNT2 branch. It is useful because memory size, bus width, and OEM board layout are the details that separate budget TNT2-family cards.

This is not a card to judge by TNT2 branding alone. It belongs in period-correct value PC documentation, where exact memory capacity and board identity matter.

Why It Mattered

The 16 MB Vanta-class entry helps the wiki track how NVIDIA and partners segmented low-cost TNT2-era boards by memory capacity and bus configuration.

Collector Notes

Record memory chip markings, exact capacity, PCB revision, vendor part number, and whether the board is PCI or AGP. These cards are often anonymous OEM pulls.

Common Failure Points

Mislabeling and overpricing are more common than exotic hardware failure. Also check for weak VGA output, memory artifacts, and damaged brackets from old office PCs.

Used-Market Caution

Buy it as a budget or OEM-history card, not as a performance TNT2. Confirm 16 MB capacity, tested 3D output, and the exact bus type before purchase.
