IBM’s PowerPC Blade — based on the PowerPC 970 processor — will offer speeds of 1.8GHz to 2.5GHz,
according to IBM
— previous announcements had the high-end at 1.8GHz.
The IBM eServer BladeCenter is one of IBM’s open source eServers and is designed for computing intensive applications such as meteorology and geological calculations and simulations.
The PowerPC 970 is expected by some industry analysts to be used in future Macs. Unveiled on October 14 (http://maccentral.macworld.com/news/0210/14.powerpc.php), the PowerPC 970 is billed by IBM as a “lite” version of its own Power4 CPU, a design created for high-end server applications. The chip design features one processor core instead of the two found in the Power4. Though the chip uses a 64-bit architecture, it’s capable of running software designed for today’s 32-bit processors, as well.
According to IBM, the PowerPC 970 also offers full symmetrical multiprocessing, has a high reliability (with parity L1, ECC L2 and parity checked system bus), is manufactured in the latest 0.13 micrometer Copper/SOI CMOS technology, has an onchip 512 KB L2 cache, and an Altivec Vector/SIMD unit.
