A closer look at GA102 die shots [RTX 3090 and RTX 3080 graphics cards]
The first detailed die shots of the GA102 GPU, which powers NVIDIA's flagship GeForce RTX 3090 and RTX 3080 graphics cards, have surfaced online.
The first detailed die shots of the GA102 silicon, which powers NVIDIA's flagship Ampere graphics cards, the GeForce RTX 3090 and RTX 3080, have surfaced online. Just like with the Zen 3 die shots from last summer, these GA102 photos were shared by our old friend Fritzchens Fritz.

In fact, INT32 and FP32 blocks take up about 25% of the GPU's area, with roughly the same amount dedicated to ROPs, TMUs, and shader processors. Twelve 32-bit GDDR6X memory controllers surround the main execution blocks, enabling a 384-bit memory bus, alongside four NVLink interfaces.
