Radeon HD 7990 vs RTX A500 Laptop comparison

According to the hardwareDB Benchmark, the RTX A500 Laptop GPU is faster than the Radeon HD 7990 in gaming.

The Radeon HD 7990 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. Despite this, the RTX A500 Laptop has a significantly higher boost clock speed. This is a frequency that can be reached if the GPU is cooled sufficiently and has enough power.

In terms of raw gaming performance in our GPU benchmark, the RTX A500 Laptop is better than the Radeon HD 7990.
