How’s the CPU inside?
In the video below, courtesy of LaughsMicroscopically, they use an Intel Celeron D320 single-core 2.3 GHz processor with 73W TDP, made in 2004 with lithography of 90 nanometers. It should be noted that with the latest technology, more sophisticated equipment will be needed to be able to take high-resolution images of transistors used today, which is why a processor with such a large lithography is used, but it still allows us to really see what the real processor looks like inside.
As you can see in the video and as we have already mentioned, they begin by breaking the processor into small pieces that can adapt to a microscope, and then zoom in on the image to see it clearly. Here you can see one of the pieces before the zoom starts doing its job. We can get such an image with a “home” microscope which can be up to 200x magnification. The piece you see has, from top to bottom, 1,668 mm.
As the image approaches, we can see the internal rotation and the connection clearly. There is no denying that the modern processor is much more complex than the Intel Celeron made in 2004, but it is still interesting to see that, once we have actually broken it, we can see the different layers on which it is built.
In this picture the transistors are already starting to look good, and you notice that the resolution has already risen by 3,500, showing pieces of 30 micrometers.
With 35,000 climbs we are already fully aware of the sensible gates of transistors. In the same picture they have already told us that the thickness of this is 196.6 nm
In any case, we recommend that you watch the full video, as below show some additional photos of how the CPU looks inside, and color them to better distinguish its components.
Interestingly, although Intel and AMD tell us about the millions of converters inside their processors, these are actually not the same as can be said, and the evidence is found in this video which shows us that there are different ways and connections between them internally. The reason for this is none other than that not all logical gates have the same function, and that is that each processor is able to perform certain commands because it is physically capable, or more or less.
