Six months after the official announcement, the third generation processor graviton3 developed by Amazon cloud (AWS) was finally put into commercial use and applied to the latest c7g instance. Amazon graviton3 also adopts the popular Chiplets small chip design, encapsulates up to seven small chips , and six auxiliary chips are surrounded by a main chip.
The modeling layout is very unique. The foreign media with big brain holes also changed the logo of Amazon cloud to P, and a little fat robot with complete hands and feet is ready to come out.
This is the internal structure diagram There are up to 64 arm architecture cores in the main chip, with eight horizontal and eight vertical distributed in mesh grid
The four on the left and right are ddr5 memory controllers. At present, the information is four channels. The lower two are PCIe 5.0 controllers
It's the first time to make the controller into a small chip alone.
The manufacturing process is unknown, and officials only revealed that about 55 billion transistors were integrated**
In terms of performance, compared with the previous generation, the single core performance is improved by 25%, the floating-point performance is improved by 2 times, the encryption and decryption performance is improved by 2 times, and the machine learning performance is improved by 3 times**
Officials also said that the delay consistency is better than amd Xiaolong and Intel Xeon, including the next generation sapphire rapids to be released by the latter.
In terms of multi-channel parallel connection, it is very strange. Amazon graviton3 is not a traditional two-way or four-way, but three-way, that is, three processors at one node , so the calculation density is half higher than that of two-way.
Amazon uses a sub card called nitro to uniformly manage the three processors, as well as storage, network and security.
