Geekbench Rosetta results

Geek Patrol today posted results from its Geekbench Preview 2 for Rosetta application, which it released yesterday. The website tested an iMac Core Duo with a 2GHz processor and 2GB of memory, running Mac OS X 10.4.5 (build 8G1454). The results were dubbed impressive, with performance running under Rosetta coming in at 40-80 percent of measured native performance. Additionally, single-threaded tests running Geekbench under Rosetta is comparable to running Geekbench natively on a Power Mac G5 1.6GHz, according the site. Two benchmarks stood out, revealing that Stdlib Allocate’s performance is "incredibly poor" under Rosetta, while Blowfish’s performance is unbelievably good--leading those involved to believe that a poor standard library implementation under Rosetta is holding back the Stdlib Allocate benchmark, while a bug in the Blowfish benchmark or Rosetta itself is inflating the Blowfish benchmark. "Overall, I don’t think Rosetta performance will be a concern for almost anyone with an Intel-based Mac."
