The input clock to the processor PLL is 333 MHz.įrom the developer guide for the MacBook Pro: The North Bridge IC implements an independent processor interface. The point-to-point architecture provides each subsystem with dedicated bandwidth to main memory. Each front-side bus has a 64-bit wide data bus. The dual, independent processor buses run at 1333 MHz and connect the processors to the North Bridge. Processor has 64 bit addressing on its bus: ![]() Supports Intel Extended Memory 64 Technology (EM64T) Two dual-core, 2.66 GHz Intel Xeon processors or configure-to-order options of two dual-core 2.0 GHz or two dual-core 3.0 GHz Intel Xeon processorsĬonnection to the North Bridge IC over a 1333 MHz frontside bus ![]() ![]() The microprocessors in the Mac Pro are Dual-Core Intel Xeon with the following features: Although I remain optimistic (my C2D 17" is on order) it would appear that the laptops are not 64 bit clean.įrom the developer guide for the Mac Pro: Processor is 64 bit capable.
