Intel UHD Graphics 615 vs Intel HD Graphics 400

Comparison of GPU cores for Intel UHD Graphics 615 and Intel HD Graphics 400 graphics cards. The GPU core data contains the number of blocks (in the AMD documentation these blocks are called Shader Engine (SE), while Nvidia calls them Graphics Processing Clusters (GPC), words are different, the essence is the same) and ROP/TMUs (Raster Processing Units). These characteristics have a great influence on the GPU computing power.

Comparison of the thermal design power of the Intel UHD Graphics 615 and Intel HD Graphics 400 GPUs. The TDP number determines the maximum power consumption of your graphics card. The specifications for computer ventilation and power supply are often based on the TDP numbers and should be optimized for it.

Here we are going to look at the types of cooling systems for Intel UHD Graphics 615 and Intel HD Graphics 400 as well as their sizes and performance. As a rule, fans with larger diameters have an advantage because they can move the same volumes of air while rotating more slowly than smaller fans. It should be noted that liquid cooling systems in addition to fans and aluminum radiators need some kind of pump, which can also be noisy.
