Users are demanding devices with longer battery life and consistently high performance, all in a thinner form factor. Microarchitecture updates to Cortex-A77 take advantage of DynamIQ efficient cores to improve
Before we dwell into the new Cortex-A77, we should take a look back at how the performance of the A76 has evolved for Arm: The A76 has certainly been a hugely successful core for Arm and its licensees. The combination of the brand-new microarchitecture alongside the major improvements that...
The A77 pushes new features with the primary goals of increasing the IPC of the microarchitecture. Arm’s goals this generation is a continuation of focusing on delivering the best PPA in the industry, meaning the designers were aiming to increase the performance of the core while maintaining the...
The Cortex-A77, therefore, has an improved microarchitecture that results in 20%-35% performance improvements. The A76 was different from its predecessors in terms of the architecture, and it was meant to serve as a baseline for the next two designs in the Austin core family: the Cortex-A77...

Cortex-A77 builds on the A76 microarchitecture The key to understanding the difference between the Cortex-A77 and A76 is to grasp what is meant by a “wider” core design. Essentially, we’re talking the ability to execute more instructions for each clock cycle, which increases the core’s...
Arm 宣布推出新一代微架構 Cortex-A77 、採用全新架構的 GPU Mali-G77 及多種新的解決方案,反映出 Arm 看好5G 的未來及其帶來的高頻寬與現代使用者透過網路進行串流、網路儲存等,並透過更高的處理效能實現 5G、物聯網、人工智能(AI)和自動駕駛的融合。
As to the new Mali-G77 GPU, there’s a brand new architecture called Valhall, which comes with a claimed 40 percent performance improvement. Energy efficiency gains from microarchitecture enhancements are said to amount to a 30 percent bump, and there’s 30 percent better performance densi...
