Photos and comments, analysis given by Roman 'der8auer' Hartung, an electronic engineer in Germany and also likes overclock, also has its own YouTube channel. He brought 2 chips to be considered in the top of Intel and AMD at the time of September 2020 to study, including Intel Core i9-10900K (using Intel's 14NM technology) and AMD Ryzen 9 3950x (use TSMC's 7nm technology). Semiconductor balls are photographed as a semiconductor area that constitutes the chip's L1 cache, the reason is because the memory cell (Memory Cell) has the most similar size and shape They are also a series of successive rectangular rectangles, so it is easier to compare than the transistors for the CPU's Calculation area (logic block) of the CPU. Before going on, invite you to look over the image of one Modern transistors with FINFET structure are being used for both the above chips. In fact, this is a picture posted by Samsung, but with TSMC and Intel, the structure is similar to that
. These two microscopic processors go scan under the scanning electron microscope (scanning electron microscope - SEM) shows that the transistor in Intel Core i9-10900K chip has a gate of 24nm, and AMD is 22nm. When placing a picture above and a plate below, it can be seen better about density TSMC transistors are higher than Intel. However, the difference is not as double as the way 14nm and 7nm suggests for you
Of course, only 1 dimension is still not enough, because the semiconductors in the 2 chips are used Finfet architecture, is a 3-dimensional architecture. Which 3-way architecture cannot be measured only in one dimension only. Hartung calls this as "silly", and what the measurement he himself done above is also "silly". Temple, the relationship between technology, for the production process is no longer available Reflecting properly. About the size of the measurements in a transistor. This has started in the 1990s. A closer number can be used so that how much the transistor is, for example, Intel 10NM and TSMC 7NM have a density of about 90 million transistors per each MM square (90 mtr / mm2). Meanwhile, the 7nm process of Intel and 5NM of TSMC is aiming at a density of 150 mtr / mm2. And once again, only the density index does not say any chip better than the chip, because A complete processor needs a lot of other factors. When you consider it in a computer, there are more factors that affect the measurement of performance
Do not argue that Intel is losing to AMD in terms of heat dissipation in some chips, many benchmark posts have just Out of that, as well as AMD CPU laptop prices tend to be cheaper than Intel at the same performance level (or sometimes AMD). But you need to clearly distinguish that only 7nm, 10nm, don't say power if comparing 2 different manufacturers. . Dịch vụ:
