Transcript of Alan Redhouses speech at AmiGBG 2003 : Comment 49 of 54 | ANN.lu |
Posted by Ole-Egil on 03-Apr-2003 10:41 GMT | In reply to Comment 48 (IanG): Excactly.
The L3 gave the G4 in this setup a 3% increase in throughput versus the board with only L1/L2.
I think that sounds about right, really. Not much application-wise should end up in the L3 cache, since it's either just running inside L1/L2, or running in memory (either small or large, not too much happens to be about 2MB in memory footprint).
Remember that if you have L3 enabled you will often get an extra penalty because of an L3 cache miss. It takes longer to miss cache 3 times than 2, so system without L3 has faster memory access...
This might be a reason... |
