Thread: Intel's secret weapon - Turbo .. what?

We all recognize what Intel is claiming to reputation immediately is that their CPU’s are such immense over lockers, but what they are actually beating is their true store speeds. How can this be? Easy, call it turbo boost when it’s running at its store speed.

Imagine about it, are you purchasing an I5 750 because it’s a 2.66 GHz CPU. So what does this really mean? Just put, over lockers can boast about getting a 2.66 GHz CPU to sprint at 3.8-4.0 GHz. actually they are over clocking their 3.2 GHz to 3.8-4.0.

Those next numbers should sound recognizable, because that’s accurately what you can do with the PII 955. So what is this all about? The skill to sell you something astounding by stating it as being much less than what it really is to start with. If you don't trust me, go look for out some results on the Intel I series processors with results with TURBO DISABLED. It’s all about advertising to exact groups IE over lockers.

Essentially you can look at the AMD cpus the similar way; they just named it in a different way. Cool N Quiet will permit the CPU to run much lower than its daily probable.

CPUs today are approximately all binned by thermal indulgence uniqueness rather than by most possible clock speed like they were in the not-so-distant history. The i5 750 surely can run at 3.20 GHz on all cores, else it would not be definite to be steady when Turbo Boost kicks in completely. However, it is only permitted to run two of those cores at that speed at any one time to limit thermal dissipation. Turbo Boost is simply a way to distribute the energy acceptable by the thermal limits to maximize presentation. If you can utilize 95 watts with your quad-core CPU, would you rather:
1. Determine how quick your CPU can run with all cores loaded and not disperse more than 95 watts. Once you have figured out that speed, do not let any cores run faster than this speed.

2. Determine how fast your CPU can run with all cores overloaded and not disperse more than 95 watts. Repeat the test with three, two and one loaded core and then allow the CPU to run cores at those (higher) speeds through those loading situation.

"We all know what Intel is claiming to fame right now is that their cpus are such enormous over lockers" No.

"But what they are actually hiding is their true stock speeds" No.

"Call it turbo boost when it’s running at its stock rate, but claim their stock speed as being much fewer." No.

"Think about it, are you purchasing an I5 750 because it’s a 2.66 GHz CPU or because it will usually run each day without over clocking at real speeds of 3.2 GHz? So what does this actually signify? Just place, over lockers can brag about receiving a 2.66 GHz CPU to run at 3.8-4.0 GHz. Actually they are over clocking their 3.2 GHz to 3.8-4.0." Once more no.

This was not at all concerning the building or how Intel CPU works. This is about Intel's advertising. Its absolute smarts to sell something and publicize it as being less than what it is. Go to best buy and talk to their sales people and see if they don't advertise it as a 2.66 GHz cpu being faster than AMD's 3.2 GHz.

Intel sells a 2.66 GHz cpu that never runs that slow. That’s promotion.

Go to newegg and see how several people put 1 egg on an AMD CPU because they had no sign that cool n calm enabled would show the CPU as a 1.6 GHz on boot up.

It might be what Intel has been doing all along and just promotion CPUs that were capable of OC damn fine.

Hell even the C2Qs (Conroe) OCed all right for a first generation quad and then the C2Qs (45nm) OCed even better at less heat output.

It’s a way to convince both the regular Joes with a CPU that’s influential enough to do something that’s terrified at it by a standard person and satisfy the enthusiasts require for speed.

It will run at 2.66GHz occasionally though. On a 4-threaded program that entirely loads all FP and integer units, it will only run at 2.66. It only clocks superior when it is below the rated thermal envelope, and consequently has some extra room to bump up the clocks. Selling it as a 3.2GHz CPU would be quite deceitful, since it does not run at 3.2GHz most of the time (as can obviously be seen by comparing its multithreaded benchmarks to an i7-965 with HT and turbo turned off). It is called a 2.66GHz CPU because it will always run at a least of 2.66GHz, despite of the load. Sometimes it will run faster, yes, but that doesn't make it a "3.2GHz" CPU.

Sure, theoretically it's advertising. It's another characteristic that they can put on the box and make it look all beautiful. However, you can't say that it's not useful and inventive. Turbo chooses how the CPU should be binned at dissimilar work loads to exploit presentation under the wattage spec. And maybe you should look at charts where turbo is disabled again. The i5 750 may not win even half the tests, really it loses by fairly a lot, but the fact that in even some of the tests it can stay speed with the pII 965 is unbelievable. Not to mention that once they are at the same clock the i5 750 beats the pII 965 in almost every benchmark. Therefore, with turbo disabled and with the clock steady, we can definitively say that the i5 building or the nehalem building in common, is greater to the pII's building. There is no smoke and mirrors when it comes to this fact because it is just true.
