I did not see this before- but again- great find from TUM_APISAK:
1. 3DMark Firestrike 2400G test with 3200MHz RAM: link.
2. Even better- Firestrike results at different RAM speed: link.
3. Firestrike Extreme and Timespy scores.
I'd like to add- that hardware in first link is Asrock ITX board with 16GB of 3200MHz RAM- so it might be the hardware we will see in 2400G reviews- because I think Anandtech mentioned this is what AMD is sending out to reviewers.
The is only a 10% increase in the score going from 2400MHZ to 3200MHZ DDR4.
