What do mobile phone cpu and gpu mean?

Mobile phone CPU refers to the mobile phone processor, which is the control center system of the entire mobile phone and the control center of the logical part; the mobile phone CPU achieves control purposes by running the software in the memory and calling the database in the memory. . The mobile phone CPU refers to the graphics processor of the mobile phone and is the brain of the graphics card. It determines the grade and most of the performance of the graphics card. On the mobile phone motherboard, the GPU chip is generally next to the CPU chip.

What does mobile phone CPU mean

Mobile phone CPU refers to the mobile phone processor.

To be precise, mobile phone CPU should be called mobile phone SOC, the full name is System on Chip, which means system-level chip in Chinese. Mobile phone SOC integrates a series of functional modules such as CPU, GPU graphics processor, RAM running memory, modom, navigation and positioning, and mobile phone baseband.

1. Mobile phone CPU is one of the functions of mobile phones that is easily overlooked by consumers in daily life. In fact, the most important thing about a smartphone with excellent performance is definitely its "core", which is the CPU.

2. It is the control center system of the entire mobile phone and also the control center of the logical part. The microprocessor achieves control purposes by running the software in the memory and calling the database in the memory.

3. Advantages: high main frequency, excellent data processing performance, the most extensive product roadmap, supporting various terminals including smartphones, tablets, smart TVs, etc., and can support all mainstream mobile operating systems , supports 3G/4G network standards. Disadvantages: Weak graphics processing capabilities and high power consumption.

4. For mobile phones, most software can run normally even under single-core conditions. Correspondingly, most software does not have corresponding design optimization for multi-core parallelism and simply increases The number of CPU cores does not mean that it can bring about a significant improvement in performance.

5. Having learned from previous years’ battles over high frequency and quantity of processors on the PC side, many people are now not optimistic about the battle over the quantity of mobile processors. At present, Android phones are undergoing an arms race-style hardware upgrade, and they are often tested on professional evaluation software to compete. In fact, ordinary consumers do not need such a high-end CPU, which means high energy consumption. Chip manufacturers including Qualcomm and Intel are now pursuing an overall balance of performance and power consumption, rather than blindly pursuing CPU frequency and core count.

What does mobile phone gpu mean?

Mobile GPU is the graphics processor.

The full English name of GPU is Graphic Processing Unit, which is translated as graphics processor in Chinese. The GPU is the brain of the graphics card, which determines the grade and most of the performance of the graphics card. On mobile phone motherboards, the GPU chip is generally next to the CPU chip. The GPU is a highly integrated chip that contains all the components necessary for graphics processing. Data is exchanged between the GPU and the CPU through RAM memory.

When the GPU performs graphics processing, it processes static pictures one by one and displays them on the screen. The characters and scenes we see in games and videos are in motion, but they are actually caused by a large number of static pictures being continuously displayed on the screen at high speed by the GPU. Since our human eyes don’t have the ability to respond so quickly, the image looks like it’s in motion. The same principle applies to televisions.

GPU is the "heart" of the graphics card, equivalent to the role of the CPU in the computer. It determines the grade and most of the performance of the graphics card. It is also the basis for the difference between 2D graphics cards and 3D graphics cards. 2D graphics chip When processing 3D images and special effects, it mainly relies on the processing power of the CPU, which is called "soft acceleration." The 3D display chip concentrates the three-dimensional image and special effects processing functions in the display chip, which is also the "hardware acceleration" function.

Simply put, GPU is a display chip that can support T&L (Transform and Lighting, gpu polygon conversion and light source processing) from the hardware, because T&L is an important part of 3D rendering, and its role It calculates the 3D position of polygons and processes dynamic light effects, which can also be called "geometric processing".

Due to the rapid development of smartphones in recent years, many large-scale applications Programs overwhelm the mobile central processing chip, often causing crashes when processing complex game graphics tasks. Therefore, a role similar to the graphics card on a PC - GPU (graphics processing chip) was introduced into mobile phones and was It is integrated into the processor and plays the role of "mobile phone graphics card". However, the mobile phone GPU is not equal to the graphics card because it is not individually packaged by the PCB board and is just a graphics chip.

In the hardware configuration of mobile phones, because there is no unified standard, the configurations of various models of mobile phones from various manufacturers are also different. However, the well-known GPUs currently used in mobile phones are mainly designed by three companies. They are Qualcomm's Adreno series, Imagination Technologies' PowerVR SGX series, and also include the Geforce graphics core from the NVIDIA Tegra 2 chipset.
