Radeon HD 7990 vs Radeon RX 560 XT benchmarks

According to the hardwareDB Benchmark, the Radeon HD 7990 GPU is faster than the Radeon RX 560 XT in gaming.

In our comparison, the Radeon RX 560 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 560 XT also has a slightly higher boost clock speed. The boost clock speed is the frequency that the GPU core can reach if the temperature is low enough. The allows for higher performance in certain scenarios.

In addition, the Radeon RX 560 XT has a significantly lower TDP at 150 W when compared to the Radeon HD 7990 at 375 W. TDP (Thermal Design Power) measures total heat output from the chip.

In conclusion, all specs and GPU benchmarks considered, will recommend the Radeon HD 7990 over the Radeon RX 560 XT.
