The UltraSPARC T1 processor with CoolThreads technology is the highest-throughput and most eco-responsible processor ever created. It's a breakthrough discovery for reducing data center energy consumption, while dramatically increasing throughput.The UltraSPARC T1, with its onboard memory subsystem, changes everything. The UltraSPARC T1 processor gives you up to eight processing cores with four threads per core. It's like a rack of servers on one chip. With up to 32 simultaneous threads in one incredibly low-power, low-heat processor, you gain the high-volume throughput you need, while saving millions on power and cooling costs.
