RTX 3060 vs RTX 4060

FP32 dense throughput reaches 12.7 TFLOPS on the RTX 3060 and 15.1 TFLOPS on the RTX 4060 with no FP16 figures published by the vendor for either card. The FP8 figure with sparsity of 242 TFLOPS applies only to the RTX 4060 and cannot be compared directly to any published value on the RTX 3060. Memory bandwidth of 360 GB/s on the RTX 3060 exceeds the 272 GB/s rating on the RTX 4060 and this difference influences maximum batch sizes during memory bound workloads. TDP of 170W on the RTX 3060 versus 115W on the RTX 4060 further separates sustained operation limits between the two cards.

The RTX 3060 becomes the preferable option in scenarios that prioritize memory bandwidth of 360 GB/s over other factors. Workloads limited by data movement rather than compute density benefit from this 360 GB/s rating even when FP32 dense performance remains at 12.7 TFLOPS. Higher TDP tolerance of 170W also aligns with environments that accept greater power draw for bandwidth advantages.

The RTX 4060 suits deployments that value FP32 dense performance of 15.1 TFLOPS combined with TDP of 115W. Availability of FP8 with sparsity at 242 TFLOPS and VRAM capacity up to 16 GB GDDR6 further support selection when efficiency and capacity matter. Lower power requirement of 115W reduces cooling demands relative to the 170W rating on the alternative card.
