Radeon R9 390 vs Radeon Vega 8 benchmarks

According to the hardwareDB Benchmark, the Radeon R9 390 GPU is faster than the Radeon Vega 8 in gaming.

In our comparison, the Radeon R9 390 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. Despite this, the Radeon Vega 8 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 Radeon Vega 8 has a significantly lower TDP at 45 W when compared to the Radeon R9 390 at 275 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 R9 390 over the Radeon Vega 8.
