Every time I talk about 64-bit processors, everyone should follow the example of Apple's A7 chip released with the iPhone 5s. Fortunately, Qualcomm did not let the manufacturers wait too long, and soon launched the Xiaolong 615, but after all, this chip is the main mid-market. In the high-end market of 64-bit processors, Qualcomm will launch the Snapdragon 810 eight-core processor and its streamlined version of the 808 processor on the flagship 8-line chip. This article will analyze them.

First, what is a 64-bit processor?

If some netizens don't understand the meaning of 64-bit, you can take a look at the picture below. In a nutshell, 64-bit processors have higher transmission efficiency and higher performance than the previous 32-bit processors, and 64-bit processors are backward compatible with 32-bit software.

Specifications: 810 vs 808

The specifications for both will be listed in the table below:

Xiaolong 808 can be regarded as a younger brother of Xiaolong 810, and the software of the two chips is fully compatible. The difference is:

1. The Snapdragon 810 has four Cortex-A57 cores, while the Snapdragon 808 has only two.

2. Snapdragon 810 uses LPDDR4 memory, while 808 uses LPDDR3 memory.

3, Xiaolong 810 supports up to 4K display, while Xiaolong 808 supports up to 2K display.

4. On the GPU side, the Snapdragon 810 uses the Adreno 430, while the Snapdragon 808 uses the Adreno 418.

It can be said that the overall configuration of the Xiaolong 808 is slightly weaker than that of the Xiaolong 810. According to Mark Shedd, marketing director of Qualcomm, the Snapdragon 808 provides OEMs with a cost-effective option. When the manufacturer does not need to support the 4K display. But when you want to enjoy the performance of Snapdragon 810, the Snapdragon 808 is very suitable.

Second, the architecture: without Krait, directly apply ARM

The Krait architecture that was previously common on Qualcomm processors has not been used on the Snapdragon 810 and 808 this time. This time, Qualcomm used ARM's Cortex-A57 and Cortex-A53 architectures on these two chips and customized them. The Cortex-A57 is currently the most powerful ARM architecture, the new ARMv8-A ISA. Improve the efficiency of the instruction set. It can be used stand-alone or as a big.LITTLE configuration with the Cortex-A53 like the Qualcomm Snapdragon 810 and 808.

The Snapdragon 810 and 808 processors also make full use of the related tools and options provided by ARM in addition to the core architecture (such as the ability to automatically shut down when the core is not used). Qualcomm's work in this area is to maximize the performance of this architecture. Come out and minimize energy consumption.
