Cache size is only one part of the overall architecture.
Perhaps a large cache is being used in order to try to make up for
higher latency (from memory)?
The use of an on-chip memory controller could help to reduce latency as opposed to an off-chip memory controller. How large is the penalty for misses in predictions? How deep is the pipeline?
What is the front-side-bus speed?
What memory speed is supported?
Oh, and how is one to benchmark the CPUs if no OS is loaded?
Here is one such comparison:
