GeForce GTX 970 vs HD 620 specs and performance

According to the hardwareDB Benchmark, the GeForce GTX 970 GPU is faster than the HD 620 in gaming.

Our database shows that the GeForce GTX 970 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 GTX 970 also has a slightly higher boost clock speed. This is a frequency that can be reached if the GPU is cooled sufficiently and has enough power.

In addition, the HD 620 has a significantly lower TDP at 15 W when compared to the GeForce GTX 970 at 145 W. TDP (Thermal Design Power) measures total heat output from the chip.

According to the results of the hardwareDB benchmark utility, the GeForce GTX 970 is faster than the HD 620.
