UHD 770 vs Radeon RX 6400 benchmarks

According to the hardwareDB Benchmark, the Radeon RX 6400 GPU is faster than the UHD 770 in gaming.

The Radeon RX 6400 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 6400 also has a significantly higher boost clock speed: the maximum frequency the chip can reach if power delivery and thermals allow.

In addition, the UHD 770 has a significantly lower TDP at 15 W when compared to the Radeon RX 6400 at 53 W. TDP (Thermal Design Power) measures total heat output from the chip.

In conclusion, all specs and GPU benchmarks considered, will recommend the Radeon RX 6400 over the UHD 770.
