Apple Power Mac G4 dual processors Model 867MHz, Model 1GHz, Model 1.25GHz The all-new Power Mac G4 features features the dual processors providing increased memory bandwidth and faster data transfer. No matter which speed you choose, you'll get the staggering performance of dual processors at 867MHz, 1GHz or 1.25GHz, which adds 500MHz to the previous generation of Power Mac G4. The original single processor 500MHz Power Mac G4 had a measured peak performance of 3.7 gigaflops. Power Mac performance has increased fivefold since then. In other words, you'd need five of the original Power Mac G4 systems to get the processing power available in the new Power Mac G4. The dual 1.25GHz PowerPC G4 processors perform 18 billion floating-point operations per second, or 18 gigaflops. The 1.25GHz G4 runs professional applications like Adobe Photoshop up to 90 percent faster than a 2.53GHz Pentium 4-based PC. To harness all this power required the new system controller designed for Xserve as well as its L3 cache and DDR memory. The processor speed gets an additional boost with an advanced cache memory architecture that provides ultrafast, dedicated memory. While accessing data from main memory is significantly faster than accessing data from the hard drive, all three new Power Mac G4s get an even faster level of memory called L3 cache. The L3 cache boosts processor function by providing fast access to data and application code at speeds of up to 4 gigabytes per second. The dual 1.25GHz model uses 2MB of high-speed DDR SRAM running at up to 500MHz on each of its chips, while the dual 867MHz and 1GHz models offer up 1MB DDR SDRAM on each of their chips. New Power Mac G4 systems feature Double Data Rate synchronous dynamic random access memory, also known as DDR SDRAM main memory. DDR SDRAM allows the system to read and write data to and from memory on both the rising and falling edge of each clock cycle. This provides twice the throughput of Single Data Rate SDRAM, which reads and writes only on the rising edge of the clock cycle. The resulting throughput between main memory and the system controller is 2.7GBps, more than double the throughput of the previous dual 1GHz Power Mac G4. Graphics processors and dual display support across the product line. AGP 4X graphics slot suuport NVIDIA GeForce4 MX graphics card (with 32MB of DDR SDRAM) Model 867MHz, ATI Radeon 9000 Pro graphics card (64MB of DDR SDRAM, quad-pipe architecture) Model 1GHz, Model 1.25GHz. As a build-to-order option you can get the NVIDIA GeForce4 Ti graphics card and its 128MB frame buffer of DDR SDRAM, which lets it perform 1.23 trillion operations per second. Each card comes with both ADC and DVI connectors for dual monitor support, without an extra PCI card. Apple Display Connector (ADC). Available to connect: 23-inch (1920-by-1200-pixel resolution) Apple Cinema HD Display, the 22-inch Apple Cinema Display, or the 15-inch or 17-inch Apple Studio Display. You also get the benefit of built-in Gigabit Ethernet for shooting large files across your LAN at high speeds, 56K modem, AirPort Card slot, two 400Mbps FireWire ports and four USB ports (two on the computer, two on the keyboard). Incidentally, FireWire, PCI expansion (four full-length 64-bit, 33MHz PCI slots with 215MB per second throughput) and Gigabit Ethernet are integrated directly into the main system controller, reducing latencies and providing superior I/O performance. In fornt a vailable optical bay for Combo DVD / CD-RW or/and SuperDrive (DVD-R / CD-RW) The dual 1GHz and 1.25GHz models come with SuperDrive, while the dual 867MHz offers the Combo DVD/CD-RW drive. Available space for a second optical drive. Data archiving on CD and DVD Optical discs are ideal for backup because they offer huge capacity in a small package that's both easy to store and lasts a long time. CDs can hold up to 650MB of data, more than 450 times as much as a floppy disk. DVDs can store 4.7GB of data, the equivalent of about 18 Zip 250 disks or 3200 floppy disks. SuperDrive-equipped Power Mac G4 lets you read and burn both CDs and DVDs that can be played in most consumer DVD players. The SuperDrive (DVD-R/CD-RW) reads DVD titles at 6x (7.8 megabytes per second), and writes to 4.7-gigabyte DVD-R discs at 2x (2.6 megabytes per second). The SuperDrive also reads CDs at 24x, writes to CD-R at 8x, and writes to CD-RW at 4x. It supports DVD-Video, DVD-ROM and DVD-R, as well as CD-ROM, CD-Audio, CD-R, CD-RW, CDI, CD Bridge, CD Extended, CD Mixed Mode and Photo CD media. All SuperDrive equipped Macs are compatible with all currently shipping 1x and 2x DVD-R media, new higher speed media will become available later (2002/2003). It is important that your SuperDrive be up to date before using this new media. Using new high-speed media The DVD Forum recently released specifications for new high-speed discs for DVD recording (4x for DVD-R and 2x for DVD-RW). All SuperDrive equipped Macs can easily be updated to be compatible with this new media. Apple is providing a quick and easy way for customers to update their SuperDrive before this new media becomes widely available. This update is available as an automatic update and as a manual update for both Mac OS 9 and Mac OS X. The Power Mac G4 also features dual ATA interfaces, one Ultra ATA/100 and one Ultra ATA/66, and you can put two drives on each interface for a total of four internal hard drives. (Or add a SCSI PCI card and mix and match for a total of four drives) Technical Specifications Processing and memory Dual 867MHz, 1GHz or 1.25GHz PowerPC G4 processors Velocity Engine vector processing unit Full 128-bit internal memory data paths Powerful floating-point unit supporting single-cycle, double-precision calculations Data stream prefetching operations supporting four simultaneous 32-bit data streams 256K on-chip L2 cache running at processor speed Up to 2MB DDR SRAM L3 cache per processor, with up to 4.6GBps throughput Up to 167MHz system bus supporting over 1.3GBps data throughput 256MB or 512MB of PC2100 or PC2700 DDR SDRAM main memory supporting up to 2.7GBps throughput Four DIMM slots supporting up to 2GB of
