Radeon RX 6500 XT vs T600 comparison
According to the hardwareDB Benchmark, the Radeon RX 6500 XT GPU is faster than the T600 in gaming.
The Radeon RX 6500 XT has a significantly 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 6500 XT also has a significantly higher boost clock speed. This is a frequency that can be reached if the GPU is cooled sufficiently and has enough power.
In addition, the T600 has a significantly lower TDP at 40 W when compared to the Radeon RX 6500 XT at 107 W. Heat output doesn't match power consumption directly but, it's a good estimate.
In conclusion, all specs and GPU benchmarks considered, will recommend the Radeon RX 6500 XT over the T600.
