GeForce GTX 950 vs Iris Plus 640 comparison

In our benchmarks, the GeForce GTX 950 beats the Iris Plus 640 in gaming performance.

In our comparison, the GeForce GTX 950 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. In addition, the GeForce GTX 950 also has a slightly higher boost clock speed: the maximum frequency the chip can reach if power delivery and thermals allow.

Next up, in terms of GPU memory, the GeForce GTX 950 has significantly more memory with 2 GiB of memory compared to 0.5 GiB. Memory size doesn't directly affect performance, but too little memory will certainly degrade gaming performance.

In addition, the Iris Plus 640 has a significantly lower TDP at 15 W when compared to the GeForce GTX 950 at 90 W. TDP (Thermal Design Power) measures total heat output from the chip.

In terms of raw gaming performance in our GPU benchmark, the GeForce GTX 950 is better than the Iris Plus 640.
