GeForce GTX 660M vs Quadro P400 comparison

According to the hardwareDB Benchmark, the GeForce GTX 660M GPU is faster than the Quadro P400 in gaming.

The Quadro P400 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. In addition, the Quadro P400 also has a slightly higher boost clock speed: the maximum frequency the chip can reach if power delivery and thermals allow.

As stated by the manufacturer, they both have the same amount of memory at 2 GiB. Lots of memory is good when playing at high resolutions or with many monitors.

In addition, the Quadro P400 has a significantly lower TDP at 30 W when compared to the GeForce GTX 660M at 50 W. TDP (Thermal Design Power) measures total heat output from the chip.

According to the results of the hardwareDB benchmark utility, the GeForce GTX 660M is faster than the Quadro P400.
