We take a look at the difference between the CPU and SoC. CPU Overall, a fairly high-speed computing, data obtained from the memory, and then a series of mathematical or logical operations. The more powerful CPU power is in fact higher, generally the higher the price in a contemporary CPU. hermès sac The CPU has a weakness - too single function, it needs the cooperation of other chips to form a complete computer, such as memory, audio chips, decoder chip, and so on.
We all know, Apple A5 core, which is a typical SoC
In the SoC (full name of system-on-a-chip, system on chip), these chips are all integrated in a slightly larger than the CPU chip - including the CPU, graphics chip, the wireless network chip. In fact, the CPU is part of the SoC, both of which form do not conflict. But on the market, both the things of the same root has a competitive relationship.
The highly integrated SoC can be a piece of equipment to achieve the size of your cell phone, but you can hardly imagine a CPU plus motherboard and graphics card can do the size of your cell phone. At the same time, due to shorter connection distance SoC than the traditional use of the CPU of the computer more power, while the reduction of the number of chips, the cost advantage. sacs chanel Of course, the SoC is not all advantages. Scalability is the biggest weakness in SoC, virtually no one thought to help their own phone to change the CPU to change the memory? But the traditional use of the CPU computer to easily do this, the expense of size and power enhancement.
In fact, the modern CPU has gradually closer to the SoC, such as the AMD the Liano processor, Intel has just released the Ivy Bridge processor, they have not in the traditional sense of the "CPU", they are integrated memory controller, the PCIE bus and (on some models) graphics chip.
In supercomputers, general-purpose CPU will be in a very long period of time to maintain absolute superiority, but in the flat panel, mobile phone, the higher degree of integration of SoC has been the traditional CPU beaten severely. sac hermes pas cher The Extremetech the article said, in the near future, SoC may completely dominate the mobile space, desktop computer again to start attacking.
