Cache hierachy on i9 12900

Hello,

Lordtourette_0-1693853695099.png

I started work on my master thesis and i will be working on the 12900. This graph is from the 12th Generation Intel® Core™ Processors Datasheet, Volume 1 of 2
It shows no connection between the MLC of the E-cores and the LLC cache. But in the document it is also stated that "The LLC is shared between all IA cores as well as the Processor Graphics." So I assume the graph is just missing that connection and that the E-cores can actually access the L3 cache 
Help would be much appreciated

Hello Lordtourette

 

Thank you for patiently waiting.

 

After reviewing the information, we found that graphs on documentation could have mistakes, however, that is not a technical issue.

 

Please visit How to Apply for an Intel® Resource and Documentation Center (RDC) and/or Intel® Developer Zone (Intel® DevZone) Account to have more information about the Cache hierarchy.

 

Best regards,
