Advantages of multi core processer
Proximity of multiple CPUs on the same die allows the cache coherence of the Chambers to work around the clock at a rate much higher than is possible if the signals have to travel outside of the slide. Combination of central processing units similar to die one significant improvement in the performance of spy Cache (alternative: Bus snooping) operations. Simply put, this means that signals between different CPUs travel shorter distances, and therefore those signals degrade less. These higher quality signals allow to send more data in a specific time period since individual signals can be shorter and need not be repeated often.
It is likely that the largest performance increase is noticed in improved response time while running processes and CPU intensive, such as virus scanning, ripping / burning media (requiring file transfer), or searching for folders. For example, if the virus starts automatic scanning while watched the movie, and the application running on the film is much less likely to be deprived of processor power, as will be set your antivirus program to different processor cores to run one of the film reading.
Assuming that the die can be aligned with the package, physically, and multi-core CPU designs require much less Printed Circuit Board (PCB) area of the Strategic Management Plan multi-chip designs. Also, the dual-core processor that uses less energy than a little by two single-core processors, mainly because of lower energy required to pay the external signals to the chip. In addition, the cores share some quarters, such as L2 cache and an interface to the front side bus (FSB). In terms of technologies competing for the available silicon die area, can be designed for multi-core designs and make use of proven CPU core library and the production of a product with a lower risk of error from the design of a new wider core design. Also, adding more cache suffers from diminishing returns.
defects In addition to the operating system (OS) support, adjustments to existing programs needed to maximize the utilization of resources provided by multi-core computing. Also, the ability of multi-core processors to increase application performance depends on the use of multiple applications within the topics. The situation is improving: for example, Engine Company valve at the source, and provides support for multi-core ([2] [3], and Crytek have developed similar technologies for CryEngine 2, which powers the game, Crysis. Engine visible Game Technologies Gamebryo include all bridge technology [4] ), which simplifies the development across multi-core platforms of the game.
Integration of multi-core chip crop production push down and it is more difficult to manage the heat from the low-density single-chip designs. Has been received Intel Partly this problem by creating the first quad-core processors by combining two designs dual-core on any one die with the cache standard, and therefore two dual core and death can be used, for the production of four cores on one die, and you need every four to work to produce a quad-core processors. From the viewpoint of architecture, at the end of the day, one CPU designs may make better use of the surface area of silicon multi-processing cores, and a commitment to develop this structure might involve a risk of obsolescence. Finally, raw processing power is not the only constraint on system performance. Contain two processing cores sharing the same system bus and memory bandwidth limits feature performer in the real world. If the essence one is close to the bandwidth of the memory is limited, and going to dual core can give only 30% to 70% improvement. If memory bandwidth is not a problem, improved 90% of the expected [citation needed]. It would be possible to apply the two CPUs that are used to run faster at the end of the day on a single dual-core if communication between the CPUs and the limiting factor, which would improve the count as more than 100%.
