Intel today officially announced the release of its next Xeon processor, Tusla.
Tulsa is the next generation on from Woodcrest which is used in Apple's current Mac Pro systems. Tulsa is also known as the Xeon 7100 series and is Dual-Core much like Woodcrest.
Tulsa boasts lower power consumption at 95 watt options that can reduce associated energy costs. Intel says the Dual-Core Intel Xeon 7100 processor series offers up to twice (2x) the performance and nearly three times (3x) better performance per watt over previous Intel Xeon MP processors--in part because of its large 16MB Level-3 cache.
It is unknown whether Apple has any plans for the high-end Xeon processor.
