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 an 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.

Graphics card specifications

Core Clock speed and Boost clock speed directly influence gaming performance, typically the higher, the better. When thermals and power delivery allow, the GPU will raise its core clock to the boost clock for even more performance. A higher core clock speed may cause a higher TDP, however.

Memory is important for high resolutions and high resolution textures in games, if you're gaming at 4K or even 8K lots of memory is required. Too little memory may result in stuttering as the GPU tries to swap and fit everything in memory.

Memory bandwidth relates to the speed at which the GPU memory can be accessed. Higher speed is better as the graphics card won't need to wait for memory access before rendering a frame to the screen.

The memory bus width doesn't directly impact performance but, it the memory bandwidth. It measures how much data can be sent at one to and from the memory.

TDP (Thermal Design Power) is a measurement of how much energy is lost as heat when a GPU is running. This has an impact on system temperatures. If temperatures get too high (typically around 100 °C or 200 °F), the GPU will lower its performance in order to prevent damage to the chip. Adequate cooling is essential for good performance. If you're comparing two laptop GPUs, you may take this into account when choosing between the two, since a cooler laptop generally runs faster for longer.
