Latest Dual CPU model tops 1.5gigaflops 28/01/02In a flurry of superlative language Apple have just announced their new range of G4 CPUs. Apple have pushed the CPU speed up another
notch with the top of the range dual 1GHz PowerPC G4 processors — with a combined performance of 15 billion floating point operations per second, or 15 gigaflops — put this fearsomely fast Power Mac G4 squarely in the lead as the ultimate high-end graphics workstation. The first Power Mac to blast through the 1GHz barrier, the new twin-engined G4 runs professional applications like Adobe Photoshop up to 72 percent faster — and crunches digital video over 300 percent faster — than a 2GHz Pentium 4-based PC.
In addition to the dual 1GHz Power Mac G4, You
can choose from two other models: the 933MHz Power Mac G4 with SuperDrive, or the 800MHz Power Mac G4 with a CD-RW drive. All three models support up to 1.5GB of PC133 SDRAM.
In the 933MHz and dual 1GHz Power Mac G4 models, faster-than-light processor speed gets an additional boost with an advanced cache memory architecture that provides ultrafast, dedicated memory with massively enhanced throughput. Accessing data from main memory is significantly faster than accessing data from the hard drive, and in these two models the system architecture takes this concept one step further with an even faster level of memory called L3 cache. The L3 cache uses 2MB of high speed, Double Data Rate (DDR) SDRAM running at up to 500MHz — boosting processor function by providing fast access to data and application code at speeds of up to 4 gigabytes per second (GBps).
You also get the benefit of built-in Gigabit Ethernet for shooting large files across your LAN at previously unheard of 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.
