Die area is drawn against the largest recorded die in the catalog. Shader dots use a labeled, card-specific ratio so both early and modern GPUs remain legible.

116 mm² die · 48 shadersDie area drawn to scale against the catalog maximum of 1,540 square millimeters. Each dot = 1 shader.116 mm² die · 48 shadersEach dot = 1 shaderDashed frame = largest catalog die (1,540 mm²)

Within its series, the GeForce GT 420 OEM ranks 48th of 54 for FP32 throughput and 34th of 94 for memory capacity. Its 50 W TDP is within the 75 W PCIe slot-power ceiling.
