NVIDIA RTX 4060 Ti 16GB Model Features 5W Higher TDP, Slightly Different ASIC Code
NVIDIA is launching 8 GB and 16 GB variants of its upcoming GeForce RTX 4060 Ti graphics card, with the 8 GB model debuting later this month, and the 16 GB model slated for July, as we learned in an older article. We are learning what else sets the two apart. Both are based on the 5 nm "AD106" silicon, by enabling 34 out of 36 SM physically present on the silicon, which works out to 4,352 out of 4,608 CUDA cores present. While the 8 GB model has the ASIC code "AD106-350," the 16 GB model gets the ASIC code "AD106-351."
The 16 GB model of the RTX 4060 Ti also has a slightly higher TDP, rated at 165 W, compared to 160 W of the 8 GB model. This is the TDP of the silicon, and not TGP (typical graphics power,) which takes into account power drawn by the entire board. The 16 GB model is sure to have a higher TGP on account of its higher-density memory. NVIDIA is likely to use four 32 Gbit (4 GB) GDDR6 memory chips to achieve 16 GB (as opposed to eight 16 Gbit ones with two chips piggybacked per 32-bit path).
