Radeon R9 390 vs Radeon RX 5500M specs and performance

According to the hardwareDB Benchmark, the Radeon R9 390 GPU is faster than the Radeon RX 5500M in gaming.

In our comparison, the Radeon RX 5500M 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 5500M also has a significantly 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 R9 390 has significantly more memory with 8 GiB of memory compared to 4 GiB. Memory size doesn't directly affect performance, but too little memory will certainly degrade gaming performance.

In addition, the Radeon RX 5500M has a significantly lower TDP at 85 W when compared to the Radeon R9 390 at 275 W. Heat output doesn't match power consumption directly but, it's a good estimate.

In conclusion, all specs and GPU benchmarks considered, will recommend the Radeon R9 390 over the Radeon RX 5500M.
