The Snapdragon 808 processor is a chipset for top-tier mobile computing terminals that supports 64-bit technology and is equipped with LTE capabilities. The Snapdragon 808 processor is expected to be released in the second half of 2014 and will be officially used in commercial terminals in the first half of 2015.
The Snapdragon 808 processor, code-named MSM8992, is a combination of two ARM Cortex A57s with four ARM Cortex A53s, and an Adreno 418 GPU with LPDDR3 RAM, which is up to 20% better than the Adreno 330. In addition, this product will be the same as the next Snapdragon 810, will be upgraded from the existing 28nm to 20nm process.
éªé¾™ 625The Snapdragon 625 is Qualcomm's first eight-core processor built on a 14nm process, which is the same process node as the Snapdragon 820 and also supports Quick Charge 3.0 fast charge technology.
Although the Snapdragon 625 is part of the Snapdragon 600 series, the Snapdragon 625 uses the latest generation of 14nm process technology, which saves 35% compared with the previous generation Snapdragon 617 and is equipped with eight Cortex-A53 processing cores. The main frequency is up to 2GHz.
The Snapdragon 625 processor uses an advanced 14nm process technology. In contrast, the Snapdragon 652, which is also positioned at the mid-end, still uses the old 28nm process. It can be seen that the Snapdragon 625 has a natural advantage in terms of heat generation and power consumption control.
In addition, the Snapdragon 625 is also the third processor in the Snapdragon 600 series, which supports the 4K video recording after the Snapdragon 650 and the Snapdragon 652, and is equipped with a dual ISP and supports up to 24 million pixel cameras. The Snapdragon 625 supports up to Cat.7 LTE networks, enabling up to 300 Mbps downstream and 150 Mbps upstream, and also supports 802.11 ac Wi-Fi. On the GPU side, the Opteron 625 is equipped with the Adreno 506 and supports the Qualcomm Quick Charge 3.0 high-speed charging protocol.
Which is better than Xiaolong 625 and Xiaolong 808?Which is better for Xiaolong 625 and Xiaolong 808? The popularity of the Snapdragon 6 series is evident. Although the Snapdragon 625 is not a high-end processor, it is still popular. Compared with the previous generation of the flagship Xiaolong 808, many netizens also love the performance of the Xiaolong 625 and Xiaolong 808. Then, this time, we will analyze the parameters of the two processors and compare the CPU/GPU performance tests.
Comparison of parameters of Xiaolong 625 and Xiaolong 808
The technology used by the Snapdragon 625 is the same as that of the Snapdragon 820. It is Samsung's second-generation finfet process 14nm LPP, and its performance is similar to that of TSMC's 16nm finfet+. The Snapdragon 625 uses a parallel multi-core multi-core architecture, eight A53 cores, clocked at 2.0GHz, GPU Adreno 510, dual-channel LPDDR3-933, and built-in X8 LTE baseband.
Snapdragon 808, six-core processor, two high-performance A57, four A53 combination, GPU Andreno418, dual-channel LPDDR3-800, LTE Cat.6/7 baseband chip. It is worth noting that this chip is a 64-bit processor with a 20-nanometer process. The Snapdragon 625 supports 64-bit and uses Samsung's 14-nanometer process.
CPU/GPU performance test, the results are as follows
Geekbench 3 test scores
In the above picture, Xiaolong 808 single-core thread performance score 1105, multi-core performance score 2779; Xiaolong 625 single-thread performance score 936, multi-core performance score 5086. This test is mainly for the CPU, the Snapdragon 808 single-core performance is slightly stronger, and the multi-core performance Snapdragon 625 has an advantage.
3DMark test scores
In the above picture, it can be seen that the Snapdragon 808 scores 17148 and the Snapdragon 625 scores 13880. This test is mainly for image processor performance (GPU), and the Snapdragon 808 GPU score is slightly higher.
By comparing CPU/GPU performance, the Snapdragon 808 has an advantage in terms of single-core performance and image processor performance, while the Snapdragon 625 achieves high scores with multi-core performance.
Many people do not know what kind of cameras are invisible cameras, and do not know how to distinguish invisible cameras, so here is how to distinguish invisible cameras.
Invisibility, as the name suggests, means that it is not easy to be seen or found, so where do such cameras exist? In fact, invisible things are hidden by the external environment, so they will not be discovered. Such invisible cameras are generally hidden in things that are more difficult to see, such as: inside the socket, inside the TV, inside the stereo, inside the fan, etc. Cameras can be hidden in various household appliances. Why should they be hidden in electrical equipment? The main reason is that these equipments have power supply and will not be used because the camera cannot be powered.
