Radeon RX 6600 XT vs Radeon RX 6600 specs and performance
For gaming, the Radeon RX 6600 XT graphics card is better than the Radeon RX 6600 in our tests.
The Radeon RX 6600 XT 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 6600 XT 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.
As stated by the manufacturer, they both have the same amount of memory at 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 Radeon RX 6600 has a slightly lower TDP at 132 W when compared to the Radeon RX 6600 XT at 160 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 Radeon RX 6600 XT is faster than the Radeon RX 6600.
