UHD vs GeForce 840M specs and performance

According to the hardwareDB Benchmark, the GeForce 840M GPU is faster than the UHD in gaming.

In our comparison, the GeForce 840M 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. In addition, the GeForce 840M also has a slightly higher boost clock speed. This is a frequency that can be reached if the GPU is cooled sufficiently and has enough power.

In addition, the UHD has a significantly lower TDP at 15 W when compared to the GeForce 840M at 33 W. TDP (Thermal Design Power) measures total heat output from the chip.

According to the results of the hardwareDB benchmark utility, the GeForce 840M is faster than the UHD.
