The SPECint and SPECfp tests measured integer and floating point peformance, and the results (see chart) should make your pulse race just a little bit faster. Performance testing - head-to-head against a 32-bit Pentium 4 and a 32-bit Xeon (essentially the dual-processor version of the Pentium 4). We ran the 64-bit PowerPC G5 through a series of SPEC tests - the industry standard for

Software to take advantage of the Power Mac G5 speed boost, becauseĪpple and IBM designed the PowerPC architecture to scale from 32- to Apple collaborated with IBM to leverage this industry-leading design for the G5, combining an optimized Velocity Engine with a new superscalar, superpipelined execution core that supports more than 200 simultaneous in-flight instructions. The POWER4 drives IBM’s successful eBusiness servers, with highly parallel processing, two double-precision floating-point units and advanced branch prediction logic. Microprocessor Report’s 2001 Analyst’s Choice Award for Best The PowerPC G5 gets its smarts from the execution core of IBM’s 64-bit POWER4 processor - recipient of the That means you won’t have a bottleneck getting information to That’s a huge leap over today’s Power Mac G4, with a bus speed ofġ67MHz.

Impractical now, maybe, but the Power PC G5 architecture allows for plenty of growth well into the future.Īnd to get at that data, the PowerPC G5 features an industry-leading 1GHz frontside bus for each processor, offering a staggering 16 GBps throughput on dual PowerPC G5 systems. Theoretically, the 64-bit data paths let the Power PC G5 access up to 4 terabytes of physical memory. So you can store entire 3D worlds, huge scientific data sets and oversized 2D images all in main memory, which lets you manipulate them faster. The new Power Mac G5 can offer up to 8GB of RAM thanks to the 64-bit G5. Any more than that requires the use of virtual memory on the hard drive, which is 40 times slower than using RAM. The 64-bit G5 speeds up to 2GHz and can address 8GBģ2-bit PCs can only use 4GB of memory. Innovation, the G5 drives the largest performance gain in the history
