Radeon R9 280X vs Radeon RX 6400 benchmarks

According to the hardwareDB Benchmark, the Radeon RX 6400 GPU is faster than the Radeon R9 280X in gaming.

In our comparison, 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.

Furthermore, the spec sheet for both these GPUs show that the Radeon RX 6400 has slightly more memory with 4 GiB of memory compared to 3 GiB. Lots of memory is good when playing at high resolutions or with many monitors.

In addition, the Radeon RX 6400 has a significantly lower TDP at 53 W when compared to the Radeon R9 280X at 250 W. TDP (Thermal Design Power) measures total heat output from the chip.

According to the results of the hardwareDB benchmark utility, the Radeon RX 6400 is faster than the Radeon R9 280X.
