IBM claims to have doubled the performance (or halved the power requirements, depending on your point of view) of its top-end processor for servers and mid-range systems. The dual-core "Power6" processor clocks to 4.7GHz, has 8MB of L2 cache, and breaks four widely used Unix performance benchmarks, according to the company.
Features of this beast include:
- 300GBps processor bandwidth -- claimed to be 30 times greater than Intel's Itanium
- First UNIX microprocessor able to calculate decimal floating point arithmetic in hardware
- Low-voltage operation, for processor blade applications, and high-voltage operation for SMP server operation
- Separate power supply "rails" for circuits that can't support low-voltage operation
- Voltage/frequency "slewing"
- Dynamic clocking
That's pretty amazing. Read more about it @ LinuxDevices.com
