Independent developers running benchmark tests of Rosetta have impressed the developers of Geekbench Preview 2 for Rosetta.
The developers have run tests on a 2GHz iMac Core Duo, and confess to being "impressed" by the results.
"I'm impressed with Rosetta; Geekbench performance running under Rosetta is 40 per cent to 80 per cent of what it is running natively. Plus, running Geekbench under Rosetta is comparable to running Geekbench natively on a Power Mac G5 1.6GHz (our baseline system), at least in the single-threaded tests," the developers state.
"Overall, I don't think Rosetta performance will be a concern for almost anyone with an Intel-based Mac," they conclude.
