At a special press event today, Apple introduced various new products. Besides the usual iPod/iTunes chit-chatter, they introduced a new Mac Mini with either a dual-core or single-core Intel processor. The new Mini sports the same form factor as the old one, and comes with an improved Front Row (support for playing streamed content using Bonjour), TV-out, and more. Note: Thanks go out to iLounge, MacCentral, and Engadget for providing live feeds.

For the things one would use a Mac Mini for, a Core Duo is *substantially* faster than a G5, clock for clock. Yonah's per-clock IPC is 40% higher than the G5's per-clock IPC going by SPECint. This should surprise no-one. The G5 has certain design features (two-cycle ALU, group dispatch, long pipeline), that keep its IPC relatively low compared to an Opteron or P-M.
These features were compromises designed to allow the G5 to run at higher clockspeeds, but IBM hit power density limitations that prevented that from happening. POWER5 tweeked the design quite a bit, namely by adding an on-die memory controller, increasing the number of rename registers, and improving the group scheduling rules, which helped integer performance quite a bit. Unfortunatley, no iteration of the G5 ever got those improvements.
