Currently, the best Intel process used for mass production of desktop processors is named “14 nm++”, while AMD Ryzen 3000 series processors on Zen 2 architecture, TSMC produces in accordance with 7 nm standards. This gives the impression that AMD has a distinct advantage.
The German overclocking enthusiast der8auer decided to clearly compare the chips produced by different processes. He took the Intel Core i9-10900K and AMD Ryzen 9 3950X processors and studied them with a scanning electron microscope. Explaining that the logical part of the processors is too different for direct comparison, der8auer chose the second level cache for comparison. Usually its elements are made with the maximum use of the technological node.
What did the comparison show? First of all, let us note that the photo shows the same fragment of the same chip. The comparison and its results are shown in the video. In short, the difference between the two chips in technological terms is less than you might expect, focusing only on the symbols.
For example, the width of the shutter in an Intel transistor is 24 nm, while in an AMD transistor it is 22 nm. The height of the shutter is also quite similar, but the AMD (more precisely, the TSMC) still has a certain advantage.
