Radeon RX 6400 vs RTX A1000 Laptop comparison

According to the hardwareDB Benchmark, the RTX A1000 Laptop GPU is faster than the Radeon RX 6400 in gaming.

Our database shows that 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 Radeon RX 6400 has a slightly lower TDP at 53 W when compared to the RTX A1000 Laptop at 60 W. This is not a measure of performance, but rather the amount of heat generated by the chip when running at its highest speed.

According to the results of the hardwareDB benchmark utility, the RTX A1000 Laptop is faster than the Radeon RX 6400.
