Turbo Boost Technology: Turbo for Real?SMT technology should increase the processor performance under multithreaded load. If the running processes do not fully load the CPU, Turbo Boost Technology comes forward. It boosts the performance by raising the CPU clock frequency by 133MHz or 266MHz above the nominal. Of course, this is a pretty small frequency increase, but it is better than nothing anyway. When we investigated the way Turbo Boost operates we found out that this frequency increase is not some rare occasion. In fact, it may take place even under pretty serious multithreaded workload.



To illustrate these ugg boots sale statements we would like to offer you some numbers illustrating the effect from Turbo Boost activation in Core i7965 Extreme Edition processor. The tests were performed with enabled SMT.



Activation of Turbo Boost technology raises the CPU performance by maximum 7%. It is a pretty logical result considering that CPU clock frequency in turbomode may only increase 8%. Some applications get minimal, barely noticeable, performance boost. These are the applications that create paralleled multithreaded load. In other words, SMT and Turbo Boost Technology are a ugg coupon code perfect match: together they are extremely efficient under practically any type of CPU workload. And when one of them cannot do much another technology comes to rescue.



It is interesting that Turbo Boost Technology will be most efficient in systems with the junior Core i7 processors. In systems like that the frequency increase will feel more noticeable and besides, this mode will get activated much more frequently. The CPU decides if the frequency can be increased basing on the current power consumption compared against the TDP standard set for the entire Core i7 lineup (130W). At the same time it is evident that junior processor models with lower clock speeds will have lower power consumption than their elder brothers and hence will have more headroom for turbomode.
