In a gasoline engine, the stoichiometric ratio of oxygen-containing air to fuel is 14.7 parts (by mass) air to 1 part gasoline. In an engine, that means if we inject more fuel, we also have to make sure we're getting more air (and thus more oxygen) to burn all the fuel, as the extra fuel won't burn unless it has more oxygen with which to combine and combust.Ĭhemistry has a word for the ideal amount of reactants in an equation to balance out with no leftovers: stoichiometry. If we want to increase power, we need to make sure we have enough of all three components of our fire triangle. It's the same at your campfire as it is inside your engine, with air flowing in to the intake combining with fuel from your fuel injectors and getting ignition from your spark plugs. If you've ever stoked a campfire to make s'mores, you probably remember the three parts of the "fire triangle": air, fuel, and ignition source. Hook it all up to a transmission connected to the wheels, and off you go! How do we make bigger explosions for more thrust? The up-and-down pistons are connected to the rotating crankshaft in the bottom of the engine, turning this vertical motion in to reciprocating motion. Inside an engine, we ignite a fuel like gasoline, and the hot, expanding fuel/air gases push down on pistons. Since Intel supplies programming examples as well as an API, I've been keeping my fingers crossed.The name of the internal combustion game is converting heat energy to movement. In a perfect world someone may put together a package to monitor clock frequency, power consumption, core usage, thread usage and CPU temperature all in onw window. Still, I can see that Turbo Boost is far more than just a marketing tool.

#What is turbo boost technology software#
It's hard to say since I'm using four unrelated apps, none of the software I'm using is designed exclusively to test the processor (with the exception of IPG), and I'm just running it on a typical rMBP with who-knows-what running in the background. I've yet to see the clock speed go all the way up to 3.7 GHz with only one core running, I've never even seen just one core running, they seem to run in pairs. I got the # cores vs clock frequency data from the Intel web site. Intel Power Gadget to show the clock frequency and power consumption graphs and smcFanControl to display the CPU temp.

I've been using TechTool Pro 7.0.2 to watch the actual cores, or MenuMeters to see each thread. I'll check primate labs in a bit for a new version. I JUST downloaded GB v3.0.0 (3244, 12880 result) and have found it to be a bit buggy. It also runs like this when I'm running and processing 8 data streams at once.

The CPU temp is at 100C° with the fans running at full speed. All 4 cores are running at 3.40 to 3.50 GHz and the CPU power usage is varying between roughly 47 Watts and 50.5 Watts. I'm currently doing a video conversion and the CPU is really cranking away. It will do 3.7 GHz with 1 core, 3.6 GHz with 2 and 3.5 GHz when 3 or 4 cores are running, On the other hand if the current task is more demanding, the clock speed can increase up to 1000 MHz over the nominal speed depending on the number of cores in use. If my computer is idling and just a few background tasks are running, the clock speed can drop to 1.7 to 2.2 GHz and the power used by the CPU is in the single digits, ~5-7 Watts. Apparently the 2.7 GHz rating is simply a nominal rating and has little to do what is actually happening at any given time. Using Intel Power Gadget I can monitor the clock speed and the power usage. On my particular processor, a 4 core i7 3820QM, the clock speed is listed as 2.7 GHz. Provided you stick to Intel's design guidelines for software and hardware (heat sinks!), I cannot imagine why you would ever want turbo-boost disabled. (I could well be wrong about this and would appreciate feedback if I am.) Given this, a system that keeps itself in turbo-boost mode, despite dangerously high CPU temperatures, sounds like it was written by someone who's incompetent. This really puzzled me, so I went a-googling and found this page, which describes a turbo-boosted Microsoft/Intel system that overheated when running some game.Īll Intel i5 and i7 processors have hardware sensors, that (when used properly) warn the BIOS or EFI when the CPU is overheating. If minimising power consumption is a primary concern (say, for laptops or in server farms) why would you buy a more expensive, turbo-boostable CPU, and then disable turbo-boosting, when you could buy a cheaper, lower-speed CPU, without the turbo-boosting ability, in the first place? Surely the more interesting question is why you would ever want to disable turbo-boost!

Why are you wanting to use turbo boost? " Mleep: "On non-apple products you would changes these setting in the bios.
