Oracle Demos New SPARC T4 Processor

MojoKid writes "Oracle is publicly demonstrating its new T4 processor today and is shipping beta test systems to selected partners. The new T4 chip is a major departure from previous designs. The T4 offers a maximum of eight cores per physical chip and keeps the T3's eight-threads-per-core limitation. The T4 compensates for its lower maximum theoretical throughput in several ways. First, the T4 is an out-of-order processor with an enhanced branch predictor. Its maximum speed is said to be at least 3GHz, nearly double that of the 1.67GHz T3. Oracle claims the chip's single-threaded performance has been significantly boosted, and expects T4 to deliver a 2x-7x speed increase in single-threaded workloads compared to T3."
