VideoCardz estimates the GA106-400 GPU has a die size of 276mm², which makes it a bit smaller than the TU116 (284mm²).
This GPU pictured below is codenamed GA106-400, the actual full chip. NVIDIA was originally planning to launch RTX 3060 with 3840 CUDA cores but as we approached the announcement the manufacturer decided that RTX 3060 will use GA106-300 instead with 3584 cores. This is why the picture has a GPU labeled as 400 – it’s an early engineering sample, and also proof that this was the original configuration of the card. Do note that we also have a picture of GA106-300, and they look identical.The NVIDIA GeForce RTX 3060 will get six Samsung K4ZAF3258M-HC16 memory modules, good for a total of 12GB GDDR6 clocked at 16Gbps.
