1, chip nm grade division: 3nm chip, 5nm chip, 7nm chip, 14nm chip and so on. A chip is a piece of semiconductor made of transistors and other devices needed for a circuit (from Jeff Dahmer). Chip is the carrier of integrated circuit.
2, the nanoscale division of the chip includes 3nm, 5nm, 7nm, 14nm and so on. Among them, the nanometer level refers to the gate length of the CMOS device, that is, the minimum wiring width or processing size. Global styleWithin the perimeter, TSMC and Samsung's 3nm process technology is more advanced, but the current yield of Samsung's 3nm is only 10-20%.
3, chip 3nm, 5nm, 7nm refers to a chip using 3nm, 5nm, 7nm process, nm is naturally short for length unit nanometer. Simply speaking, x nm refers to the gate width of the complementary oxide-metal semiconductor field effect transistor formed on the CPU, also known as the gate length.
4, the chip process of 28nm, 14nm and 7nm represent the transistor gate in the semiconductor manufacturing processTherefore, the processing process of the chip is of course the smaller the better.
The smaller the length unit, the better because of higher performance and lower power consumption. Higher performance: As the nanometer size shrinks, the number of transistors continues to increase, making the chip faster and more powerful.
Demo model: Huawei MateBook X System version: win10 The smaller the cpu nanometers, the better. As the technology goes from 90 nanometers to 65 to 45, smaller and smaller. For example, 45 nanometers is more advanced than 65 nanometers, and the more advanced the process, the smaller the size of the transistor,More transistors can be packed into the same area of wafer.
The smaller the CPU nanometers, the better. In the process of producing CPU, the precision of the integrated circuit, that is, the higher the precision, the more advanced the production process.
Nanometer is a unit of length size. The smaller the technical node, it means that the production will be more difficult, the required level of technology will be higher and higher, so the technology is more and more advanced.
The smaller the CPU nanometer, the better, the smaller the number of transistors, the lower the energy consumption and higher performance. In the microcomputer, also known as the microprocessor, all the operations of the computer areControlled by CPU, the performance index of CPU directly determines the performance index of microcomputer system.
TransistorThe density is different. In the same area, the density of the transistor on the 5-nanometer chip is larger. Transistors on 7-nanometer chips are less dense. Different optimizations in terms of performance and power consumption. The 5nm chip has good performance and low power consumption. 7nm chips are less powerful and consume more power.
With the development of the process, the performance of the 5-nanometer chip is 15% higher than that of the 7-nanometer chip, and the power consumption is 33%, and the performance of the 3-nanometer chip is 10%-15% higher than that of the 5-nanometer chip, and the power consumption is reduced from 25% to 30%.
The energy consumption of the 5nm chip can be reduced by about 30% on the same performance, and the 5nm core can be reduced under the same energy consumptionThe performance of the chip is about 15% higher than that of the 7nm chip.
Nanochips are better than 7-nanometer chips, but ultimately it is up to the machine to get the most out of the chip. The chip is just a small part in many hardware, and the final operation result depends on other hardware to cooperate with each other to play the effect of the chip.
The main difference between nanometers and 7 nanometers is transistor density. The former has more than 700 million transistors per square millimeter, 80% higher than 7nm. Hard numbers are hard to understand. In simple terms, 7nm can accommodate three G76 coresThe heart can hold five now. Another improvement is the optimization of performance and power consumption.
Tianguet 8000 compared to Snapdragon 778 performance is stronger, the comprehensive performance will be better, between the two will be more recommended to start with Tianguet 8000 models. As a light flagship chip product in Mediatek's "Tianguet Team", the Tianguet 8100 chip has the following two main characteristics: high energy efficiency and high performance.
Tianguet 8000 processor good. The first is the performance advantage, the performance of the Tianguet 8000 processor is stronger than that of the Snapdragon 782 processor, the Snapdragon 782 is a mid-range processor, the performance of the Tianguet 8000 reaches the high-end level, the performance is not much different from that of the Snapdragon 870, so from the performance point of view, the Tianguet 8000 processor is good. Teguet 8000 More power saving.
Which good Tianguet 8000 and Snapdragon 778g compared to Snapdragon 778 performance is stronger, the comprehensive performance will be better, between the two will be more recommended to start Tianguet 8000 models. The 8100 is better. Tianji 8100 adopts TSMC5nm technology. Compared with Tianji 8000 game performance improved by 20%, CPU energy efficiency increased by 25% compared with the previous generation.
Which is good, Tianguet 8000 and Snapdragon 778g: The performance is definitely better. The Tianguet 8000 belongs to the mid-to-high-end mobile phone processor, while the Snapdragon 778g Attributes Mid-range mobile phone processor. From the mobile phone ladder map, you can see that the 778G is at the end, and the performance of the Tianguet 8000 and Tianguet 8100 is almost among the best.
However, the Tianguet chip has some shortcomings in the adjustment of the camera, so the camera level under the same level of chip is not as good as the Snapdragon cpu. Tianguet 8000 and Snapdragon 778g which good Tianguet 8000 compared to Snapdragon 778 performance is stronger, the comprehensive performance will be better, between the two will be more recommended to start Tianguet 8000 models.
In the chip production process is better than Snapdragon 778G, to provide users with the current flagship mobile phone 6nm production process, compared with 7nm production process, can better reduce the power consumption of the chip, improve the performance of the chip.
g and 855 Application scenarios According to the above performance comparison, we can conclude: 855 performance is better, suitable for high-end flagship mobile phones, can provide a more smooth user experience and better game performance.
The two are basically differentFrom the performance point of view, the Snapdragon 855 is slightly higher than the Snapdragon 778g in terms of multi-core performance, but the Snapdragon 778g is better than the Snapdragon 855 in terms of single-core performance.
The Snapdragon 778G is on par with its own Snapdragon 855 and rival Samsung's Exynos9820. At the same time, it is slightly better than the Tianguet 1000L, not as good as the Kirin 990.
1, process technology: Tianji 810 adopts 6nm systemThe Snapdragon 765G uses 7nm process technology. The 6nm process has an 18% increase in transistor density relative to the 7nm process, which means that in the same area, the 6nm process can integrate more transistors, thereby improving the performance and energy efficiency of the chip.
2, the nm process is more advanced than the 7nm process, and may have better power performance. Second, the Tianji 8000 is equipped with its own developed Tianji 8000U processor, including two ARM Cortex-A78 large cores and six ARM Cortex-A55 small coresThe GPU is Mali-G77 MC9.
3, Snapdragon 782G is good, the main reasons are: process technology, CPU performance, GPU performance, AI performance, 5G network support. The Snapdragon 782g uses a 7nm process, while the Tianguet 8200 uses a 6nm process.
