Iris 540 vs Radeon HD 8790M specs and performance

For gaming, the Radeon HD 8790M graphics card is better than the Iris 540 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 Iris 540 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.

According to the results of the hardwareDB benchmark utility, the Radeon HD 8790M is faster than the Iris 540.
