Radeon R9 270 vs Radeon RX 460 benchmarks

For gaming, the Radeon RX 460 graphics card is better than the Radeon R9 270 in our tests.

The Radeon RX 460 has a slightly higher core clock speed. This is the frequency at which the graphics core is running at. While not necessarily an indicator of overall performance, this metric can be useful when comparing two GPUs based on the same architecture. In addition, the Radeon RX 460 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.

As stated by the manufacturer, the Radeon RX 460 has significantly more memory with 4 GiB of memory compared to 2 GiB. Lots of memory is good when playing at high resolutions or with many monitors.

In addition, the Radeon RX 460 has a significantly lower TDP at 75 W when compared to the Radeon R9 270 at 150 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 Radeon RX 460 is faster than the Radeon R9 270.
