GeForce RTX 3060 Ti vs Radeon RX 6800 comparison
According to the hardwareDB Benchmark, the Radeon RX 6800 GPU is faster than the GeForce RTX 3060 Ti in gaming.
The Radeon RX 6800 has a slightly higher core clock speed. This is the frequency at which the graphics core is running at. While not necessarily an indicator of overall performance, this metric can be useful when comparing two GPUs based on the same architecture. In addition, the Radeon RX 6800 also has a slightly higher boost clock speed: the maximum frequency the chip can reach if power delivery and thermals allow.
As stated by the manufacturer, the Radeon RX 6800 has significantly more memory with 16 GiB of memory compared to 8 GiB. If you're planning at playing games at high resolutions with high-quality textures, you will need a lot of memory.
In addition, the GeForce RTX 3060 Ti has a slightly lower TDP at 200 W when compared to the Radeon RX 6800 at 250 W. TDP (Thermal Design Power) measures total heat output from the chip.
In conclusion, all specs and GPU benchmarks considered, will recommend the Radeon RX 6800 over the GeForce RTX 3060 Ti.
