Iris Plus 640 vs GeForce GT 750M comparison

According to the hardwareDB Benchmark, the Iris Plus 640 GPU is faster than the GeForce GT 750M in gaming.

The GeForce GT 750M 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. Despite this, the Iris Plus 640 has a slightly higher boost clock speed. The boost clock speed is the frequency that the GPU core can reach if the temperature is low enough. The allows for higher performance in certain scenarios.

In addition, the Iris Plus 640 has a significantly lower TDP at 15 W when compared to the GeForce GT 750M at 50 W. This is not a measure of performance, but rather the amount of heat generated by the chip when running at its highest speed.

According to the results of the hardwareDB benchmark utility, the Iris Plus 640 is faster than the GeForce GT 750M.
