Mac users can expect good performance from Apple's forthcoming Intel-powered Macs, developers report.

AppleInsider reports "impressive" performance from the systems, which run a build of OS X 10.4 on a machine driven by a 2.6Ghz Pentium 4, with 2MB L2 cache, 800Mhz front-side bus, 1GB memory and an Intel graphics processor.

The report states that these systems take "as little as ten seconds" to boot, and the speed gains mean these test systems compete favourably against Apple's top of the line G5s.

Emulation software Rosetta (developed by Transitive Technology) also performs "impressively", "nothing like Classic", the report claims.
