An IBM press release details the features and specs of the prototype PowerPC 970, Big Blue’s desktop derivative of its Power4. This CPU is expected by many to be used by Apple in brand new case-design desktop Power Macs perhaps as soon as this July. The 970, a 64-Bit CPU, is also to be used in IBM’s blade servers. According to IBM, the PowerPC 970 prototypes are now running at between 1.8GHz-2.5GHz. The CPU offers full symmetrical multiprocessing, a 512KB L2 cache, AltiVec and system bus throughput of up to 6.4GB p/s.
The PowerPC 970 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, and runs at frequencies ranging from 1.8 GHz – 2.5 Ghz. Therefore the IBM PowerPC 970 is the fastest PowerPC so far.
Further technical highlights of the PowerPC 970:
? Onchip 512 KB L2 Cache
? Altivec Vector/SIMD unit
? 6.4 GB/s I/O system bus throughput
