Where is Longwei? Qualcomm Snapdragon chip inventory

Qualcomm has been racing in the mobile phone chip market for many years. Thanks to the large number of communication patents that “buy the baseband to send the processor”, Qualcomm has always been in the position of market dominance. With the intensification of market competition, many mobile chip brands have gradually been squeezed out of the market, such as the ambitious intel, the smash hit Texas Instruments, and Qualcomm has been living very well, in addition to the monopoly status factor, Strong performance and good compatibility are also advantages that cannot be ignored. Below, the first domestic hardware detection platform Master Lu will come to check the development process of mobile CPU in the past few years.

Since Qualcomm named the Chinese name of the Snapdragon series processor as “骁龙” in 2012, it has carried out a series of positioning and sorting on its original product line, and has divided the new and old product lines into 800 series and 600. Series, 400 series and 200 series. The original S series has withdrawn from the historical stage, so we will not introduce the products under the S series. Master Lu will introduce the current product planning classification, and clearly clarify the Qualcomm chips.

Qualcomm Xiaolong 200

Nowadays, the entry-level products, but some S series chips were not mentioned at the time of the release, but with the release of competing products, the performance gradually lags behind, so that it is finally classified as the most introductory product. The Snapdragon 200 will mainly appear in products below the thousand yuan. For example, the MSM8X25 is the legendary cost-effective Qualcomm quad-core. You will often see it in a machine with a few hundred yuan, that is, the specific model that does not tell him.

The Snapdragon 200 series is mainly a 45nm process product, and there are also individual 28nm products. The quad-core Cortex A5 CPU/quad core ARM Cortex A7 architecture is commonly used, and the single core speed is between 1.2GHz and 1.4GHz. The corresponding GPU has Adreno 203 or Adreno 302. There are also some commonalities that are divided into standards, such as a maximum support of 1280x800 resolution, and a maximum support of 800W pixel camera. The more common models are 8110, 8210, 8610, 8112, 8212, 8612, 8225Q and 8625Q.

Master Lu V3.0 has improved the scoring system and enhanced the GPU weight. Therefore, the overall score of the Snapdragon 200 product will be somewhat enhanced, but the enhancement is very small. The score is mainly floating between 10,000 and 13,000 points. After all, it is an entry level. The product.

Qualcomm Xiaolong 400

The Snapdragon 400 is dedicated to thousands of models. Most of the series are dual-core. Because the process is generally 28nm process + Krait 300/200 architecture, the performance of the processor is better than the A5 architecture's 4-core Snapdragon 200. .

The Snapdragon 400 single core is up to 1.7GHz. Built-in Adreno305 GPU, supports up to 1080P resolution and 1350W pixel camera. The series includes 8026, 8028, 8228, 8628, 8928, 8926, 8030AB, 8226, 8230, 8230AB, 8626, 8630, 8630AB, 8930 and 8930AB, so many models include many tablet-free PCs. There are also products for different network standards. Although there are many models, the products are not too many. The more common 8x30 and 8x26 series scores in the system of Lu Master V3.0 from 15000 to 23000. The performance fluctuates greatly depending on the number of cores and the main frequency.

Qualcomm Xiaolong 600

This is the one with the fewest processors, only 8064T, 8064M. The 2013 "explosion" APQ8064 does not belong to this series, but belongs to the Xiaolong S4 pro. The Snapdragon 600 uses a 28nm LP quad-core Krait300 CPU with a single core speed of 1.9GHz and adds LP-DDR3 memory.

The most obvious enhancement of the Opteron 600 is the Adreno 320 GPU, which has 300% more graphics performance than the previous Adreno 2XX GPU and supports advanced graphics and computing APIs including OpenGL ES 3.0, DirectX, OpenCL, Renderscript Compute and FlexRenderTM2. .

Figure 2: Qualcomm Xiaolong series processor 3D test scores

In the 3D test scores of Master Lu V3.0, due to the greater progress of the Adreno320 GPU, the APQ8064 has a very obvious growth in graphics game performance, which became the most discussed product of the year, which also led to the Xiaomi 2 at that time. Hot.

Qualcomm Xiaolong 800/801

This may be the most familiar series of ordinary consumers. The Qualcomm Xiaolong 800 appeared in the conferences of various mobile phone manufacturers in 2013-2014. Various manufacturers are promoting this processor and using the dragon. The 800 means that the best processor in the moment is used, and there is really no rival in terms of performance and network compatibility.

The Qualcomm Snapdragon 800 features a 28nm HPm quad-core Krait400 CPU with a single core speed of 2.3GHz and an updated Adreno330 GPU that delivers up to 50% better graphics performance. The Qualcomm Snapdragon 801, which was said to be the most in 2014, was upgraded at 0.2 GHz, and it also brought adjustments in other details.

From the horizontal comparison of the test results of Master Lu, you will find that the progress of 801 is still there, especially in the performance of eMMc.

Push Button Switches

The Push Button Switches, also known as the control button (referred to as the button), is a low-voltage electrical appliance that is manually and generally can be automatically reset. The Push Button Starter Switch is usually used to issue a start or stop command in the circuit to control the turning on and off of electrical coil currents such as electromagnetic starters, connectors, and relays.

The On Off Push Button Switches refers to a switch that pushes the transmission mechanism with a button to make the movable contact and the static contact open or close and realize circuit switching. It is a master control device with a simple structure and a wide range of applications. In the electrical automatic control circuit, used to manually send control signals to control connectors, relays, electromagnetic starters, etc.


Push Button Switches


This Pushbutton Switches is a kind of electric device that is used to switch on and off the small current circuit when the action is released. Generally used in AC and DC voltage below 440V, the current is less than 5A in the control circuit, generally do not directly manipulate the main circuit can also be used in the interconnection circuit. In actual use, in order to prevent desperation, different marks are usually made on the buttons or painted with different colors, and the colors are red, yellow, blue, white, black, green, and the like.



Pushbutton Switches


The Momentary Push Button Switch could be divided into metal push button switches and Led Light Switches and ordinary snap button type, mushroom head type, self-locking type, self-resetting type, rotary handle type, with indicator light type, lighted symbol type and key type, etc., with single button and double Buttons. Generally, it adopts a water-storage structure, which consists of a button cap, a return spring, a static contact, a moving contact and a casing. It is usually made into a composite type, and has a pair of normally closed contacts and normally open contacts, and some products can pass. The series connection of multiple elements increases the number of contact pairs. There is also a self-contained button that automatically holds the closed position when pressed, and can be turned on only after the power is turned off.

When the Metal Switches is not pressed, the movable contact is connected with the upper stationary contact. The pair of contacts is called a normally closed contact. At this point, the movable contact is disconnected from the following static contact. The pair of contacts is called a normally open contact: the button is pressed, the normally closed contact is open, the normally open contact is closed, and the button is released. Restore the original working state under the action of the return spring
