Radeon Vega 8 vs Radeon HD 8790M comparison

For gaming, the Radeon Vega 8 graphics card is better than the Radeon HD 8790M in our tests.

Our database shows that the Radeon HD 8790M 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. 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 terms of raw gaming performance in our GPU benchmark, the Radeon Vega 8 is better than the Radeon HD 8790M.
