GeForce GTX 1660 SUPER vs Radeon RX 6600 benchmarks
For gaming, the Radeon RX 6600 graphics card is better than the GeForce GTX 1660 SUPER in our tests.
The Radeon RX 6600 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 6600 also has a slightly higher boost clock speed. This is a frequency that can be reached if the GPU is cooled sufficiently and has enough power.
Furthermore, the spec sheet for both these GPUs show that the Radeon RX 6600 has slightly more memory with 8 GiB of memory compared to 6 GiB. Memory size doesn't directly affect performance, but too little memory will certainly degrade gaming performance.
In addition, the GeForce GTX 1660 SUPER has a slightly lower TDP at 125 W when compared to the Radeon RX 6600 at 132 W. Heat output doesn't match power consumption directly but, it's a good estimate.
In terms of raw gaming performance in our GPU benchmark, the Radeon RX 6600 is better than the GeForce GTX 1660 SUPER.

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.
