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.

294 mm² die · 1,536 shadersDie area drawn to scale against the catalog maximum of 1,540 square millimeters. Each dot = 16 shaders.294 mm² die · 1,536 shadersEach dot = 16 shadersDashed frame = largest catalog die (1,540 mm²)

Within its series, the GeForce GTX 680 Mac Edition ranks 42nd of 121 for FP32 throughput and 64th of 143 for memory capacity. Its 195 W TDP is above the 75 W PCIe slot-power ceiling.
