Quadro K620 vs Radeon HD 8950 comparison

According to the hardwareDB Benchmark, the Quadro K620 GPU is faster than the Radeon HD 8950 in gaming.

The Quadro K620 has a slightly 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 Radeon HD 8950 has significantly more memory with 3 GiB of memory compared to 2 GiB. Memory size doesn't directly affect performance, but too little memory will certainly degrade gaming performance.

In addition, the Quadro K620 has a significantly lower TDP at 45 W when compared to the Radeon HD 8950 at 225 W. TDP (Thermal Design Power) measures total heat output from the chip.

In terms of raw gaming performance in our GPU benchmark, the Quadro K620 is better than the Radeon HD 8950.
