AMD will let out “anti- -Hyper-Threading” in this year: the secret weapon Of socket AM2

Still in April this year appeared rumors about the fact that the company AMD develops the technology, reverse on its action of the known technology Hyper-Threading from Intel. Let us recall that the latter makes possible for one processor to substitute by itself two virtual nuclei, and to divide between themselves the flows of data. Intel forewent further development “virtual [mnogoyadernosti]” in favor real [mnogoyadernosti], but it does not exclude the possibility of the revival of this technology in the new performance.
According to our personal information, obtained from the familiar with the plans AMD of sources, already in this year the company will open access to technology, reverse on its action Of hyper-Threading. If the latter divides the resources of one physical processor nucleus, then know-how AMD will make it possible to unite the resources of two physical nuclei for accelerating the tasks, which optimally work on the mononuclear processors. For example, this will make it possible to double a quantity of decoders, and “united” processor will carry out six instructions for time. This already by itself can become not bad answer to the output of the processors Of conroe, and the debut of the corresponding technology for sure takes place on the eve on July 24.
The corresponding functionality is already build it the binuclear processors Of athlon 64 X2 in execution Socket AM2. For its activation it will be required to only renew the driver of processor and basic input-output system of maternal pay. The company Of microsoft must let out appropriate [patch] for the operating systems, which will make it possible to receive two nuclei Of athlon 64 X2 as one. By the way, according to the preliminary data, processor will be able to be switched into “united” regime dynamically, depending on the type of the utilized application. It is no secret that many tasks as before win from the use of productive mononuclear processors, but not working at the lower frequencies binuclear processors.
It is amusing, that AMD itself will be simultaneously occupied by the popularization of the platform 4x4, designed for the enthusiasts, thinkers of its existence without [mnogozadachnosti]. Judging by everything, two sufficient different approach will be spread on the different market niches. In any case, the possibility “to unite” two nuclei into one virtual will manage to the possessors of the processors Of athlon 64 X2 in execution Socket AM2 absolutely free of charge, if we do not consider possible expenditures for the running off of new basic input-output system and driver for the operating system.
It is no secret that the start of the technology Of hyper-Threading sometimes caused reduction in the productivity, since two virtual nuclei began to dispute with the attempt to determine the priority of processing the flows of data. Is possible to assume that the antipode of the technology Of hyper-Threading from AMD will make it possible to avoid such annoying conflicts, and even will increase the operating speed of system.
In proportion to the appearance of new information about this know-how AMD we will acquaint you with it on the pages of our site.
