Intel resurrects the war in MHz CPU
turbo mode in microprocessors (Intel Turbo Boost and AMD Turbo Core) delivers higher performance in all applications, to automatically increase the operating frequency considerably when running few processing threads, and slightly when running several them, thus providing the best performance depending on running operations (single threaded or multi-threaded).
But so far Turbo mode is offered as an additional feature of the microprocessor, not as one that defined it, and the latter is what intel has been doing for the last few days on its website, which falsely reported the frequency of its microprocessors Turbo core i7 and Core i5, making us think that operate at a frequency higher than 400MHz real, when in fact it is only able to achieve this frequency when using applications that do not use more than two threads.
Intel Turbo Boost 2.0
Turbo Boost 2.0 technology of Intel microprocessors work by increasing the frequency of the microprocessor dynamically, depending on the workload, wherein, taking for example the quadruple core CPU Core i7-3770K (3.5Ghz) we have:
- Loads with one to two threads: The frequency is increased by 400MHz (3.9GHz).
- Loads with three or more threads: The frequency increases 200MHz (3.7GHz).
With this we need but the base frequency is 3.5GHz microprocessor, the microprocessor actually operates from 3.7 to 3.9GHz, so we have to strictly, this microprocessor running at 3.7GHz, which operates frequently when their four cores are active.
Turbo Boost 2.0 becomes a publicity stunt
I’ve always wondered what was the reason he avoided a direct report chipmaker turbo frequency of its microprocessors, for example in the case of the 3.7GHz Core i7-3770K and although Intel now started with this measure, unfortunately informs the often less demanding as Turbo Mode: 3.9GHz in this case, a figure that clearly is a half-truth, since this chip is simply not capable of running with four cores active at that frequency, at least not in its factory settings (the overclock is another matter.)
There are clear reasons for this measure because its Intel microprocessors perform well per cycle and do not need to resort to such tricks, but apparently some additional mhz remain a good selling point.
