Arm Introduces Cortex-A77 CPU and Mali-G77 GPU

Orange Pi Development Boards

Arm unveiled its Cortex-A76 CPU and Mali-G76 GPU right before Computex 2018, so it should come as no surprise that the company decided to make announcements for the upgrades before Computex 2019 with the just introduced Arm Cortex-A77 processor, and Mali-G77 GPU.

Processor highlights:

  • 64-bit Armv8 CPU with support for Armv8.1 and Armv8.2 extensions, as well as Armv8.3 with LDAPR instructions only
  • Up to 4 processors per cluster
  • Cache – 64KB L1 I-Cache / D-Cache, 256KB to 512KB L2 Cache, optional L3 Cache between  512KB and 4MB
  • Improved performance for mobile and laptop devices enabling AAA-gaming, faster web-browsing and application launch time.
  • Brings always-on, always-connected feature set of mobile to laptop devices
  • Compatible with the newly announced Mali-G77 and machine learning (ML) processor.

Cortex-A77 vs Cortex-A76 Single Thread Benchmark

Compared to Cortex-A76, Cortex-A77 yields up to 20% improved IPC performance with similar efficiency. The new IP core is basically an upgrade over A76 with the same key features but better performance, as you can find in the comparison in the developer page.

Mali-G77 GPU

The Arm Mali-G77 GPU is the first GPU based on the Valhall architecture and is said to provide 30% performance density uplift and 30% improvement on energy efficiency compared to Mali-G76 GPU. Arm also reports a 60% improvement in machine learning applications.

Mali-G77 is scalable from 7 to 16 cores, and support the usual recent API including OpenGL ES 1.1, 2.0, 3.1, 3.2, Vulkan 1.1, and OpenCL 1.1, 1.2, 2.0 Full Profile. More details can be found on the developer’s page.

First cortex with uop cache, AFAIK.

Where did you read that? (I don’t see it in this article)

Still no open source drivers?

How many years ago ARM aquired Falanx and how many years takes it for patents to expire?

They never do a Nvidia, AMD and release drivers for the main OS?

Great, a faster core, with a bit of luck A76 will not be considered premium anymore and we can hope to see it land on SBCs next year.

As much as I’d love to see that — 7nm on SBCs next year is a bit of a stretch.

A76s will be in next year’s Rockchip which will be 8nm. Good enough for me.

Ah, yes, I had forgotten about that one. Perhaps we will get it in SBCs after all..

It depends how the SoC is built, I have not tracked down the final truth, but have heard claims one SoC is 12nm Core, 16 nm GPU.
Time will tell.

Unless someone adds the rest of Chinese manufacturers to the ban and the brits follow their idol…
