| IBMs new processors to exceed 5 Ghz
IBMs
Power6 processor will be able to exceed 5 gigahertz in a high-performance
mode, and the second-generation Cell Broadband Engine processor from IBM,
Sony and Toshiba will run at 6 GHz.
Intel and Advanced Micro Devices have turned to adding
multiple processing cores on each slice of silicon. Thats effective
when computers are running numerous tasks at the same time, but increasing
the clock speed means that an individual task will run faster.
The first-generation Cell Broadband Engine chip, co-developed
by IBM, Sony, and Toshiba, has appeared in Sonys PlayStation 3 game
console and can run at 4 GHz. The second-generation chip will run at 6
GHz. Moreover, the new chip will have a dual power supply that increases
memory performance.
The IBM Power6 processor for servers which is due to
ship in 2007, will run between 4 and 5 GHZ. The chip consumes less than
100 watts, a power range comparable to mainstream 95-watt AMD Opteron
chips and 80-watt Intel Xeon chips. The Power6 processor has 700 million
transistors and measures 341 square millimeters. Like the second-generation
Cell, Power6 is built with a manufacturing process with 65-nanometer elements.
In September, Intel showed a glimpse of a prototype chip
with 80 cores that can perform a trillion mathematical calculations per
second. The chip measures 275 square millimeterssmaller than the
303-square-millimeter area indicated in Septemberand runs at 4 GHz.
The chip has 100 million transistors and dissipates 98 watts of waste
heat.
