Check out the specifics of a technological tour-de-force.
Apple and IBM jointly developed the PowerPC G5, world’s first 64-bit desktop processor. With two double-precision floating-point units, advanced branch prediction logic and support for symmetric multiprocessing, the PowerPC G5 processor builds on previous PowerPC designs, combining an optimized Velocity Engine with a superscalar, super-pipelined execution core that can execute more than 200 simultaneous in-flight instructions. This high-bandwidth core has over 12 discrete functional units that process massive amounts of instructions in parallel.

Native compatibility with 32-bit application code
For PC users, going from 32-bit to 64-bit computing requires migrating to a 64-bit operating system (and purchasing the 64-bit applications that will work on it) or running a 32-bit operating system in slow-as-molasses emulation mode. The PowerPC G5, however, offers a seamless transition to 64-bit performance: Current 32-bit code — such as Mac OS X, the Mac OS 9 Classic environment and existing applications — runs natively at processor speed. With no interruptions to your workflow. And no additional investment in software required, period.

That’s because, unlike competing instruction sets, the PowerPC architecture was designed from the beginning to run both 32-bit and 64-bit application code. This enables the PowerPC G5 processor to run Mac OS X natively for an immediate performance boost. In addition, as applications are optimized and as Mac OS X is further enhanced for the PowerPC G5 processor, performance gains will be even more dramatic.

  1. Tests performed by Apple in June 2003 using preproduction Power Mac G5 units. The Power Mac systems ran a PowerPC G5 — optimized version of Photoshop 7.0.1 including optimized AltiVecCore, ACE, and BIB Carbon Libraries; the Dell Dimension ran Photoshop 7.0.1.
  2. “World’s fastest” based on SPEC CPU2000 benchmark results and leading professional application performance tests against 3GHz Pentium 4 — based Dell Dimension 8300 and dual 3.06GHz Xeon-based Dell Precision Workstation 650. SPEC CPU2000 benchmarks run with GCC 3.3 compiler and independently tested; professional applications tested by Apple, June 2003.
  3. Based on SPEC CPU2000 benchmark results against 3GHz Pentium 4 — based Dell Dimension 8300 and dual 3.06GHz Xeon-based Dell Precision Workstation 650, run with GCC 3.3 compiler and independently tested, June 2003.
  4. Selected models.
  5. 1GB = 1 billion bytes; actual formatted capacity less.
  6. Achieving data rates of 54 Mbps requires that all users have an AirPort Extreme Card and connect to an AirPort Extreme Base Station. If any user of Wi-Fi certified 802.11b products joins the network, that user will get up to 11 Mbps and AirPort Extreme network users will get less than 54 Mbps. Actual speed will vary based on range, connection rate, site conditions, size of network, and other factors.
  7. Check with manufacturer for compatibility.
  8. Second Apple flat-panel display requires Apple DVI to ADC Adapter, sold separately.
  9. Actual rates will vary.
