I was thinking about the next pc upgrade and RAM came into my mind. I am using three years old ddr3-1333 memory sticks, the oldest component in my rig.
Okay, the question is: Will faster memory give me more performance. To answer my question I ran some tests and compared scores for different RAM clock.
And the short answer is: No, highter memory clock won't give you better performance.
But the long answer is: Yes, pc with faster RAM works insignificantly faster.
Here is an example
firstname.lastname@example.org ghz with ddr3-1333 (1372) scores 8.30 in cinebench 115.
email@example.com ghz with ddr3-1800 (1854) scores 8.40 in cinebench 115.
The difference between ddr3-1333 and ddr3-1800 is 0.1 pts.
