How EAS helps make the Google Pixel the fastest Android phone
The Google Pixel smartphones are among the fastest Android phones on the market. Energy Aware Scheduling (EAS) is partly why the phone is so smooth.
Far back in the past when Linux was just an idea in the mind of Linus Torvalds, CPUs were single-core entities which required an immense amount of energy for little power. The first ever commercially available processor, the Intel 4004, ran at a clock-rate of 740kHz on a single core. Back then, there was no need for a load scheduler. Load scheduling was reserved for the dual-core "behemoths" such as the IBM Power 4 which came out some decades after. These ran at a beastly 1.1GHz to 1.9GHz and required programs and the system to utilize these cores correctly. How did we get from these machines to software algorithms that make use of multiple cores? You may have heard of Energy Aware Scheduling (EAS) on our forums before. It's part of the reason why the Google Pixel smartphones perform so well. What's so great about EAS and how did we even get to this point? Before we can explain that, we need to talk about Linux load schedulers.
Xiaomi Mi Note 2 XDA Review: A Capable Flagship and a Solid First Step Onto the World Stage
Check out XDA's extremely in-depth Xiaomi Mi Note 2 review and learn how it compares to similarly priced phones. Did Xiaomi make the right move?
Xiaomi’s worldwide launch has been heralded for years, and with the Xiaomi Mi Note 2 it looks like the final pieces are falling into place. As Xiaomi’s first flagship phone to offer a model with worldwide frequency band support, the Mi Note 2 offers an exciting look into what we can expect from Xiaomi as they continue to expand internationally.
We reached out to Qualcomm to get a better look at the Snapdragon 821 processor that is making an appearance in the upcoming Google Pixel and Pixel XL, the Asus ZenFone 3 Deluxe, the Xiaomi Mi 5s, and the LeEco Le Pro 3. With the Snapdragon 821 in the Pixel phones running at the same clock speed as the regular Snapdragon 820, many people were asking what benefits the new SoC brings, and why choose it if they’re not going to use the higher clock speeds it can bring.
