It turns out that the desktop variant of the GeForce RTX 3060 is less powerful than its mobile variant, at least on paper. The RTX 3060 for notebooks is based on the higher-end variant of the GA106 die with 3,840 FP32 cores and a boost clock of up to 1,703MHz, whereas the desktop-grade 3060 is limited to 3,584 cores, but a higher boost clock of 1.78GHz or 1,780MHz.
Although both GPUs use the same GA106 die, the mobile version features the nearly fully enabled variant with 3,840 cores working out of the total 4,096. The desktop variant disables two SMs, bringing the total core count down to 3,584. At the same time, the latter does feature twice as much video memory (12GB), while the mobile GPU is limited to half as much.
The bus width is the same on both the dies at 192-bit, but as expected the mobile die is paired with slower memory chips (12Gbps), reducing the bandwidth to 288GB/s.
