Ode to Apple

In a rather rare and surprising pre-Macworld Expo move (Macworld Expo 2008 will be from January 15 to 18 at the Moscone Center, San Francisco), Apple unveiled a retooled Mac Pro Desktop machine and a new Xserve server – calling them the fastest Macs ever. The ultra-end Mac Pro features Advanced Micro Devices ATI Radeon HD 2600 XT graphics card with 256MB standard memory. The new 45-nanometer quad-core Xeon processor from Intel, can be equipped with up to 32GB of RAM and as much as 4TB of Disc Drive Storage.

More power with less power
Inside the new Mac Pro is the latest technology from Intel – Quad-Core Intel Xeon “Harpertown” processors. These processors run at blazingly fast speeds up to 3.2GHz.

Cache count
A huge amount of L2 cache — 12MB per processor — keeps frequently used data and instructions close to the processor cores and improves overall performance. 6MB of cache is shared between pairs of processor cores, allowing an individual core to use all the available shared cache at any one time.

Built at full tilt With the fastest Xeon architecture available, the new Mac Pro features 1600MHz dual independent frontside buses. These 64-bit buses give each processor a direct connection to the system controller and deliver improved processor bandwidth of up to 25.6GB per second — 20 percent greater than the previous Mac Pro. With a new system architecture, speedier system buses, and fast 800MHz DDR2 fully buffered DIMM memory, Mac Pro memory throughput is up to 1.6 times faster than before. Every Intel Xeon processor features an enhanced SSE4 SIMD engine. Capable of completing 128-bit vector computations in a single cycle, SSE4 is ideal for transforming large sets of data, such as applying a filter to an image or rendering a video effect.

Smarter memory
The Mac Pro incorporates a 256-bit-wide, fully buffered memory architecture with Error Correction Code (ECC), which corrects single-bit errors and detects multiple-bit errors automatically. These features are especially important in mission-critical or compute-intensive environments. Apple designed a more stringent thermal specification for the Mac Pro FB-DIMMs, so the internal fans spin at slower speeds and keep the system quiet.

Prices for the Mac Pro start at $2,799 for a machine running two 2.8-GHz quad-core Xeons with 2GB of memory, the ATI Radeon HD 2600 XT graphics card and a 320GB SATA drive. At the top of the configuration line, a machine tricked out with two 3.2-GHz processors, 32GB of memory, the Nvidia Quadro FX 5600 graphics card, a RAID card and four 1TB internal drives prices out at a whopping $18,199. The extra RAM alone adds $9,100 to the bottom line of that machine. The Mac Pro comes with Mac OS X 10.5 “Leopard”, Apple’s newest client operating system.

Xserve

Along with the new Mac Pro announcement, Apple also refreshed its Xserve server to include the same 45nm Penryn-family Xeon processors, the first time since August 2006 that it has punched up its 1U rack-mounted server. The Xserve, which starts at the same $2,999 as its base-line predecessor, comes with an unlimited client license edition of Leopard Server, boasts three drive bays and can be equipped with up to 32GB of memory. For $2,999, buyers get a server running a single 2.8-GHz quad-core Xeon, 2GB of memory, an 80GB SATA drive and dual Gigabit Ethernet on board.

The new Xserve is actually the more important of the two systems, argued an analyst at Technology Business Research Inc., because it “draws attention to the Leopard Server operating system’s capabilities as a small-business or departmental server for organizations with limited IT support.” While both new models significantly improve on characteristics of the machines they replace, the analyst said the Xserve and the Leopard Server operating system make a more compelling case.
