They work best under the assumption that they operate on enormous quantities of relatively homogeneous data that require to be processed with the same instructions/program 'DSP POWER INVISIBLE IN BENCHMARKS. Nowadays, they are stream processors that have massive amounts of computational power, thanks to the use of parallel units operating on wide data types. Such computational units were originally designed to work on information streams such as audio or visual signals. Independant synthetic tests show between 30% to 100% faster data stream from one generation to the other depending on the task. The memory sub-system has been greatly improved, and data can flow much faster when compared to Snapdragon 810. The single-core performance is impressive, but Apple remains ahead of the game. For example, Apple’s dual-core processors typically lose in MT benchmarks, but still perform very well in the real world, because synthetic tests on a massive 6-8 array of cores are a very poor proxy for real app CPU usage. Multithreaded (MT) is not that important in my opinion. Qualcomm will compete with chip designs from Samsung ( Exynos) and Huawei/ HiSilicon (Kirin) that may feature more cores (is it better? Not always), so I expect the competition to perform better in some synthetic tests that run across all cores at once, like Geekbench and others multi-threaded benchmarks. This allows Qualcomm to pick its own transistor budget and tweak the Kryo core in an optimal way.

From a software standpoint, Kryo behaves just like those ARM cores, but internally, Qualcomm has built the Kryo core from the ground up to use its unique optimizations. Kryo is compatible with the ARMv8-A instruction set that was developed for the ARM A35/ A53/ A57/ A72 cores. 'THE SINGLE-CORE PERFORMANCE IS IMPRESSIVE' The idea is similar to ARM’s big.LITTLE idea, except that the configuration is different. As you may have guessed, the handset can utilize them at different times, depending on the workload at hand. Two of them run at a maximum of 2.2GHz (best performance), while two others run at a maximum of 1.6GHz (best power). Snapdragon 820 is a quad-core processor that comes with four identical Qualcomm Kryo custom 64-bit cores. This is the equivalent of your CPU (Intel/AMD) in a PC. The performance “bread and butter” of any SoC comes from its central computing units (CPUs) and memory sub-system.

Snapdragon 820 is a system-on-chip (aka SoC) which is composed of many compute sub-units such as the Kryo CPU cores, the Hexagon 680 DSP, the Spectra image processor, the Adreno 530 graphics processor and the X12 4G LTE modem - just to mention the big ones. Qualcomm is using Samsung’s 14nm FinFET (gen2) process that was initially used for the Exynos processor of the Galaxy S6-series. The smaller FinFET process alone should be responsible for a significant share of the overall performance and power usage improvement (~10%?).

FinFET allows chip designers to find the optimum tradeoff between power usage/ leakage and computing performance. 14nm ( nanometer) is one of the smallest process currently used in chip production.įinFET is a transistor design that was created to function on particularly small transistors (~20nm and below) in which electric current leakage becomes a big problem. Typically, new processes are used in a way that improves the power consumption for a given workload, resulting in better performance-per-watt than previous generations. The smaller they are, and the higher the “compute density” potential is. The semiconductor process describes the size and electrical properties of the chip’s building blocks.

On this new architecture, Qualcomm claims to have made improvement across the board as seen in the presentation slide below: Built with the 14nm FinFET semiconductor process The CPU cores, the GPU, the DSP, the modem, the image processors - it’s all been upgraded from Snapdragon 810. Built from the ground upĭon’t be fooled by Qualcomm’s numbering scheme, Snapdragon 820 is a chip built from the ground up and nearly every in it has changed. Here is some information from Qualcomm that shows what’s new, and how much they think the performance is better.

For communications, LTE or WiFi upgrades are the main drivers of improvements, so we will look into that as well.įinally, there are items such as fast battery charging or security that can also be enabled by a new product. Obviously, the performance relative to “power consumption” ( perf./Watt) is an important thing as well since battery life remains the #1 priority for most users. CPU, GPU and memory bandwidth are the main performance factors to observe. Now is a good time to refresh your mind about what this chip is about, and how it is compared to its predecessors.

As we head towards Mobile World Congress (MWC) 2016, the onslaught of smartphone designs using Qualcomm’s new Snapdragon 820 SoC (processor) is going to hit.
