Radeon Vega 8 vs Iris Xe benchmarks
For gaming, the Iris Xe graphics card is better than the Radeon Vega 8 in our tests.
By comparing the spec sheets, both the Radeon Vega 8 and the Iris Xe have the same base clock speed. Despite this, the Radeon Vega 8 has a significantly higher boost clock speed: the maximum frequency the chip can reach if power delivery and thermals allow.
In addition, the Iris Xe has a significantly lower TDP at 15 W when compared to the Radeon Vega 8 at 45 W. Heat output doesn't match power consumption directly but, it's a good estimate.
According to the results of the hardwareDB benchmark utility, the Iris Xe is faster than the Radeon Vega 8.
