As a core component of a smartphone, the processor has always been the user's concern. For example, the Samsung Galaxy S5 and the Sony Xperia Z2, which have just been released, are equipped with Snapdragon 800 series processors, but the specific performance difference is probably not familiar to ordinary users.
In fact, the Snapdragon 800 series processor can be said to be Qualcomm's most successful high-end processor products, and there are many derivative versions, such as MSM8974, MSM8974AB, and MSM8974AC. Below, we will help you understand the performance differences between these versions through a simple and direct comparison.
Several versions and performance differences of Snapdragon 800/801
First of all, we need to know which models of processors are used by which phones, which is a bit confusing. The Samsung Galaxy S5 is powered by the Snapdragon 801 (MSM8974AC) processor, while the Sony Xperia Z2 is also part of the Snapdragon 801, but the model is actually the MSM8974AB, which is the same as the Samsung Galaxy Round and earlier. So, Z2 as a new generation flagship, why not configure the real Snapdragon 801 (MSM8974AC)?
The reason for this seems to be because Qualcomm temporarily decided to create an upgraded version of MSM8974AB, which is the MSM8974AC used by S5. Older models such as the Xperia Z1, LG G2, Nexus 5, etc., are actually powered by the MSM8974 version. What are the performance differences between the three versions? You can find the answer from the table below. For the sake of clarity, the Snapdragon 600 processor (APQ8064T) has been added to the table for comparison.
Comparison of several Qualcomm Snapdragon processor version parameters
We can see that the MSM8974, MSM8974AB and MSM8974AC processors all use the same Krait 400 architecture, which is also a quad-core, 28-nm process. The graphics card model and camera support resolution and video encoding performance are exactly the same; the difference is It is the processor frequency, the graphics card frequency, the memory frequency, and the ISP frequency. Further, the difference between the MSM8974AB and the MSM8974AC is only the processor's main frequency and the graphics card's main frequency, and the other parts are identical. Obviously, the performance of the AC version is the most powerful.
Performance comparison of MSM8974, MSM8974AB and MSM8974AC
Of course, the performance difference between AB and AC version is not big, because their memory frequency and other parts are exactly the same, so the actual performance of Samsung S5 and Sony Z2 is not too big. However, the older versions of the LG G2 and Nexus 5 models are inferior to the Samsung S5 in terms of processor frequency, graphics performance, and memory performance.
There are also some new performance upgrades that are not reflected in the table. For example, the MSM8974AC can support the faster eMMC 5.0 flash standard, enabling up to 400MB/s transfer. Compared with MSM8974, MSM8974AB can also support dual Sim card dual boot and four-level LTE network.
How to choose?
Obviously, Snapdragon 801 can be said to be an overclocked version of Snapdragon 800 (AB version), the performance difference between the two is not big. But in terms of parameters, Samsung Galaxy S5 is still the most powerful Android smartphone at present. The processor and graphics card have the highest frequency, which can theoretically achieve better application and game running experience. Of course, the overall experience of the phone is also related to battery life, screen size, storage options and system interface effects, and some exclusive features can not be ignored.
As for the higher performance, we may expect Snapdragon 805 to be officially commercialized. I believe that the Android models in the second half of the year will use this processor, such as Xiaomi 4, Samsung Galaxy Note 3, LG G3 and other models. look forward to.
"Non-burning, nicotine for users, low tar content. As the heating temperature (below 500℃) is lower than the combustion temperature of traditional cigarettes (600-900℃), the harmful components produced by tobacco high-temperature combustion pyrolysis and thermal synthesis are reduced, and the release amount of side-flow smoke and environmental smoke (second-hand smoke) is also greatly reduced."
Heating non - combustion products are electronic devices containing tobacco. When you heat them, they produce a nicotine-containing vapor that you can inhale.
They are different from traditional cigarettes and work by heating tobacco to a very low temperature. Tobacco is heated to 350 ° C in a heat-incombustible device, while traditional cigarettes burn at up to 900 ° C.
Still, the temperature at which non-combustion products are heated is high enough to vaporize and inhale harmful chemicals.
Although both are electronic devices, heated non-combustible products are also different from e-cigarettes or steam devices. These usually use chemical liquids and do not necessarily contain nicotine. E-cigarettes tend to heat liquids to around 250 degrees Celsius to produce vapor.
