Quadro K620 vs Radeon HD 7670M benchmarks

For gaming, the Quadro K620 graphics card is better than the Radeon HD 7670M in our tests.

Our database shows that the Quadro K620 has a significantly 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.

Next up, in terms of GPU memory, the Quadro K620 has significantly more memory with 2 GiB of memory compared to 1 GiB. If you're planning at playing games at high resolutions with high-quality textures, you will need a lot of memory.

In addition, the Radeon HD 7670M has a significantly lower TDP at 20 W when compared to the Quadro K620 at 45 W. Heat output doesn't match power consumption directly but, it's a good estimate.

According to the results of the hardwareDB benchmark utility, the Quadro K620 is faster than the Radeon HD 7670M.
