Radeon R9 270 vs Radeon RX 6800 comparison

In our benchmarks, the Radeon RX 6800 beats the Radeon R9 270 in gaming performance.

In our comparison, the Radeon RX 6800 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 6800 also has a significantly 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.

As stated by the manufacturer, the Radeon RX 6800 has significantly more memory with 16 GiB of memory compared to 2 GiB. Memory size doesn't directly affect performance, but too little memory will certainly degrade gaming performance.

In addition, the Radeon R9 270 has a significantly lower TDP at 150 W when compared to the Radeon RX 6800 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 6800 is faster than the Radeon R9 270.
