GeForce RTX 3080 vs Radeon RX 6900 XT comparison
For gaming, the Radeon RX 6900 XT graphics card is better than the GeForce RTX 3080 in our tests.
Our database shows that the Radeon RX 6900 XT 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. In addition, the Radeon RX 6900 XT also has a slightly higher boost clock speed: the maximum frequency the chip can reach if power delivery an thermals allow.
As stated by the manufacturer, the Radeon RX 6900 XT has significantly more memory with 16 GiB of memory compared to 10 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 Radeon RX 6900 XT has a slightly lower TDP at 300 W when compared to the GeForce RTX 3080 at 320 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 6900 XT over the GeForce RTX 3080.

Graphics card specifications
Core Clock speed and Boost clock speed directly influence gaming performance, typically the higher, the better. When thermals and power delivery allow, the GPU will raise its core clock to the boost clock for even more performance. A higher core clock speed may cause a higher TDP, however.
Memory is important for high resolutions and high resolution textures in games, if you're gaming at 4K or even 8K lots of memory is required. Too little memory may result in stuttering as the GPU tries to swap and fit everything in memory.
Memory bandwidth relates to the speed at which the GPU memory can be accessed. Higher speed is better as the graphics card won't need to wait for memory access before rendering a frame to the screen.
The memory bus width doesn't directly impact performance but, it the memory bandwidth. It measures how much data can be sent at one to and from the memory.
TDP (Thermal Design Power) is a measurement of how much energy is lost as heat when a GPU is running. This has an impact on system temperatures. If temperatures get too high (typically around 100 °C or 200 °F), the GPU will lower its performance in order to prevent damage to the chip. Adequate cooling is essential for good performance. If you're comparing two laptop GPUs, you may take this into account when choosing between the two, since a cooler laptop generally runs faster for longer.
