“That may not sound like anything special for a processor whose clock ticks at a rate approaching 5 billion times each second. But Power6 can count to 10–and perform numerous other mathematical operations–with the decimal digits 0 through 9 rather than the binary digits of 0 and 1 used by conventional computers,” Stephen Shankland reports for CNET News.
“Binary math is the ordinary mode for Power6 and a natural for computers: The two digits can conveniently be represented by voltage differences and other yes-or-no, up-or-down, on-or-off differences. But humans, graced with 10 digits, generally opted for base 10, or decimal, mathematics, and about a little more than half of numeric [data] stored in commercial databases is decimal, McCredie said,” Shankland reports.
Shankland reports, “Power6, a dual-core chip IBM will begin manufacturing this year for servers going on sale in mid-2007… The Power and PowerPC lines will grow one step closer together with Power6, which incorporates the AltiVec instruction set that speeds up many multimedia tasks. AltiVec, also known as VMX, increases efficiency by letting a single processing instruction be applied to multiple data elements. That’s helpful for video and audio tasks on desktop machines, but servers will benefit as well in, for example, high-performance computing tasks such as genetic data processing, McCredie said.”
“Adding AltiVec was a tradeoff, he said. It’s a valuable feature, but electrical current ‘leakage’ problems in today’s chipmaking technology mean that even idle parts of a chip consume power and produce waste heat,” Shankland reports. “Power6 will run at speeds of 4GHz to 5GHz, IBM has said. ‘It will be closer to 5GHz than it is to 4GHz,’ McCredie said.”
