Radeon RX 470 vs Radeon RX 550X benchmarks

For gaming, the Radeon RX 470 graphics card is better than the Radeon RX 550X in our tests.

The Radeon RX 550X has a slightly 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 550X also has a slightly higher boost clock speed: the maximum frequency the chip can reach if power delivery and thermals allow.

Next up, in terms of GPU memory, the Radeon RX 470 has significantly more memory with 8 GiB of memory compared to 4 GiB. Lots of memory is good when playing at high resolutions or with many monitors.

In addition, the Radeon RX 550X has a significantly lower TDP at 50 W when compared to the Radeon RX 470 at 120 W. TDP (Thermal Design Power) measures total heat output from the chip.

In terms of raw gaming performance in our GPU benchmark, the Radeon RX 470 is better than the Radeon RX 550X.
