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.

470 mm² die · 240 shadersDie area drawn to scale against the catalog maximum of 1,540 square millimeters. Each dot = 2 shaders.470 mm² die · 240 shadersEach dot = 2 shadersDashed frame = largest catalog die (1,540 mm²)

Within its series, the GeForce GTX 285 Mac Edition ranks 108th of 121 for FP32 throughput and 109th of 143 for memory capacity. Its 204 W TDP is above the 75 W PCIe slot-power ceiling.
