Radeon Vega 8 vs GeForce RTX 4090 specs and performance

In our benchmarks, the GeForce RTX 4090 beats the Radeon Vega 8 in gaming performance.

In our comparison, the GeForce RTX 4090 has a significantly higher core clock speed. The core clock speed (or base speed) is the frequency at which the GPU core runs. This metric makes sense when comparing GPUs of a similar architecture or generation. In addition, the GeForce RTX 4090 also 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.

In addition, the Radeon Vega 8 has a significantly lower TDP at 45 W when compared to the GeForce RTX 4090 at 450 W. TDP (Thermal Design Power) measures total heat output from the chip.

In terms of raw gaming performance in our GPU benchmark, the GeForce RTX 4090 is better than the Radeon Vega 8.
