HD 620 vs GeForce RTX 4090 benchmarks

According to the hardwareDB Benchmark, the GeForce RTX 4090 GPU is faster than the HD 620 in gaming.

The GeForce RTX 4090 has a significantly 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 GeForce RTX 4090 also has a significantly higher boost clock speed: the maximum frequency the chip can reach if power delivery and thermals allow.

In addition, the HD 620 has a significantly lower TDP at 15 W when compared to the GeForce RTX 4090 at 450 W. TDP (Thermal Design Power) measures total heat output from the chip.

According to the results of the hardwareDB benchmark utility, the GeForce RTX 4090 is faster than the HD 620.
