Radeon Vega 8 vs Radeon RX 7800 XT specs and performance

According to the hardwareDB Benchmark, the Radeon RX 7800 XT GPU is faster than the Radeon Vega 8 in gaming.

Our database shows that the Radeon RX 7800 XT 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 Radeon RX 7800 XT also has a slightly higher boost clock speed. This is a frequency that can be reached if the GPU is cooled sufficiently and has enough power.

In addition, the Radeon Vega 8 has a significantly lower TDP at 45 W when compared to the Radeon RX 7800 XT at 263 W. This is not a measure of performance, but rather the amount of heat generated by the chip when running at its highest speed.

In conclusion, all specs and GPU benchmarks considered, will recommend the Radeon RX 7800 XT over the Radeon Vega 8.
