Bus Speed A bus is a subsystem that transfers data between computer components or between computers Types include frontside bus (FSB), which carries data between the CPU and memory controller hub;. The 4790K spends less than half the time that the 4770K does working on frames that take longer than 33 milliseconds to produce—and at 47GHz, those long frame rendering times are further reduced. Create a computer with robust processing performance using this Intel® Core™ iK BXIK processor that uses Enhanced Intel® SpeedStep and Intel® Turbo Boost to ensure fast, efficient operation with a processor speed up to 44GHz.
