Intel processors nehalem generation will obtain the integrated memory controller . High end Bloomfield, for example, will have three-channel memory controller with DDR 3-1333 support . The mass four core processors lynnfield will have only two memory channels . AMD Company already transferred the memory controller in the processor, and tests showed the effectiveness of this solution .
Associate tried to estimate, the gain of Intel processors from the passage to use the integrated memory controller .
Associates assert that with the appearance of nehalem generations processors , which will possess the 64-bit memory controllers , the effectiveness of memory use will increase from present 50-60% to 90%. Thus, the system bus will cease to be the bottleneck,.
According to certain evaluations , lynnfield processors with two-channel memory controller , can increase the memory capacity to 18,5-20,1 Gb/s using DDR 3-1333. The three-channel memory controller Of bloomfield processors will allow to raise this value to 30 Gb/s.
