Hello, how do you obtain the TDP data for the various Graviton processors? What are your sources or methods for collecting this data?

There are other possible explanations assuming the CPU and DRAM are identical. Firmware can be tuned for HPC via DRAM and prefetch settings, or simply set a higher max power (Neoverse V1 has 3 power gears: https://www.anandtech.com/show/16640/arm-announces-neoverse-v1-n2-platforms-cpus-cmn700-mesh/3 )

In reply to Will. Yup. I think that is the base clock, and they overclock the heck out of it to get the extra performance in the 3E version. There is no other explanation.

Note AWS states frequency of Graviton 3E as 2.6GHz: https://github.com/aws/aws-graviton-getting-started#:~:text=2500MHz-,2600MHz,-Turbo%20supported

In reply to Maury Wood. Correct! I can't read my own chart. . . .

I think the transistor count in the article needs to be updated to “billions” from “millions”.

In reply to Slim Albert.

I’m not really worried about optimizing my workloads for a specific processor architecture. A lot of software is using Java / Python / PHP / etc and should run unchanged. There are, of course, HPC and other specialized workloads where it takes a lot of work to optimize for vector instructions, etc – but most people in IT aren’t working at this level. The bigger risk may be tying yourself to the services the cloud vendors offer, such as DynamoDB.

In reply to Eric Olson. "This warning could apply equally to software developers who optimise their code for a processor design that is only available for rent from a single cloud provider." This is so true!
