Radeon R9 390X vs Radeon R9 Fury X specs and performance

According to the hardwareDB Benchmark, the Radeon R9 Fury X GPU is faster than the Radeon R9 390X in gaming.

Furthermore, the spec sheet for both these GPUs show that the Radeon R9 390X 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, both the Radeon R9 390X and the Radeon R9 Fury X have an identical TDP. This is not a measure of performance, but rather the amount of heat generated by the chip when running at its highest speed.

In conclusion, all specs and GPU benchmarks considered, will recommend the Radeon R9 Fury X over the Radeon R9 390X.
