GeForce RTX 2080 vs GeForce RTX 3060 comparison
In our benchmarks, the GeForce RTX 2080 beats the GeForce RTX 3060 in gaming performance.
The GeForce RTX 2080 has a slightly higher core clock speed. The core clock speed (or base speed) is the frequency at which the GPU core runs. This metric makes sense when comparing GPUs of a similar architecture or generation. Despite this, the GeForce RTX 3060 has a slightly higher boost clock speed: the maximum frequency the chip can reach if power delivery and thermals allow.
Furthermore, the spec sheet for both these GPUs show that the GeForce RTX 3060 has significantly more memory with 12 GiB of memory compared to 8 GiB. Memory size doesn't directly affect performance, but too little memory will certainly degrade gaming performance.
In addition, the GeForce RTX 3060 has a significantly lower TDP at 170 W when compared to the GeForce RTX 2080 at 250 W. Heat output doesn't match power consumption directly but, it's a good estimate.
According to the results of the hardwareDB benchmark utility, the GeForce RTX 2080 is faster than the GeForce RTX 3060.
