Introduction
What happened a month ago intelovskie decline in the prices of processors is an important milestone towards multi-CPU computers to the user. Finally, the price had fallen to quad processor dual-level models. Specifically, the younger of the Quad Core 2 in the official price-list in the estimated amount of one senior Core 2 Duo. The amount is, by the way, is $ 266, which in our view, is more than enough to make processors with four computing kernels much more popular solution than they were before.
It described the situation and prompted us to implement another study in which we decided to pit "playing" dual-core and quad-CPU same value, Core 2 Duo E6850 and Core 2 Quad Q6600. Indeed, the problem of choosing among them more suitable for their needs processor has been a large number of users, since these products are offered in retail stores today for a comparable price. This data processors are so different in their characteristics, that the clear choice of the optimal solution can not make even some professionals. Indeed, these are not only the CPU number of different cores, they also differ significantly on the clock frequency and the frequency used tires.
There is the view that the most demanding applications issued or updated recently, can utilize the advantages of multicore processors. At the same time, this is not always true in the case of old programs and games, most of which continue to operate one or two of computational flow. Therefore, to make the situation of some uniqueness and to resolve the question of whether the use of quad instead of high-frequency dual processors in different applications, we decided to hold a special testing.
For more intrigue in the confrontation Core 2 Duo E6850 and Core 2 Quad Q6600 can make, and the fact that both of these processors used in its semiconductor basis is the same nucleus. The fact is that the modern Quad Intel processors consist of a pair of dual-crystal mounted in a number of LGA775 package. Therefore, the dual-and quad processors Core family of the same conduct can be expected to disperse. This, in turn, gives hope for the opportunity to disperse Core 2 Quad Q6600 to frequencies reached at overclocking Core 2 Duo E6850. That is, comparing 266 - dollar positions overklokerskih competitors with promises to be even more exciting than their testing in the staffing regime. Moreover, and the Core 2 Duo E6850, and the recently released Core 2 processors use a new Quad Q6600 stepping G0, which, according to our research, has a slightly superior payload capability.
Core 2 Quad Q6600 against Core 2 Duo E6850: general information
Nearly complete picture of the strengths of a solution can be obtained by conducting formal comparisons processor specifications Core 2 Duo E6850 and Core 2 Quad Q6600 (new stepping G0).

Advantages of Dual Core 2 Duo E6850 over Quad Core 2 Quad Q6600:
At 25% higher clock frequency, allowing show better performance in applications that are not optimized by multithreading.
Higher frequency tires, ultimately raising the speed memory subsystems work. Peak capacity highways processor memory to CPU with 1333 - Gatifloxacin tyres is 10.7 GB / sec to 8.5 Gb / s with a processor 1067 - Gatifloxacin tyres.
At 46% lower heat generation, which allows the use of relatively simple and inexpensive cooling systems, including the dispersal.
Advantages Quad Core 2 Quad Q6600 over dual-core Core 2 Duo E6850:
Twice a larger number of cores, allowing to achieve high performance with multithreaded applications, and in multitasking environments.
Twice more total cache memory of the second level. This is especially significant for users of Windows Vista, as that operating system includes tools for the intellectual nucleus of flows with the general or separate L2 cache.
Thus, each processor has its pluses and minuses. Nevertheless, the principal disadvantage of Core 2 Quad Q6600 it looks low clock frequency, which is 2.4 GHz. But, then, this flaw can be corrected overclocking, as well? Let us learn about the more processors available in our test lab, and see whether the dispersal quad Core 2 Quad Q6600 to work on the same frequencies, as well as dual-core Core 2 Duo E6850.
Description of the test system
For experiments to disperse and performance, we gathered a special test system, which, in addition to processors, entered components, specifically targeted to disperse.
The basis of our overklokerskoy platforms, it was decided to use a new motherboard ASUS Blitz Extreme targeted at gamers producer-enthusiasts. This - the only motherboard in the market on the basis of a set of logic Intel P35 Express with support for DDR3 SDRAM, which is due to additional Crosslinx chip technology offers support for the scheme Crossfire PCI Express x8 + PCI Express x8.
However, in the first instance, the fees are interested in us because of its overklokerskomu potential. It allows you to change the FSB frequency in the range of 200 to 800 MHz, offers access to all available in the Intel P35 multiplier FSB: DRAM, and has great potential to change the voltage. Thus, the voltage at the processor can be increased to 1.9 V, on the north bridge chipset - up to 2.03 V at DDR3 memory - up to 3.04 V. In addition, the fees have to change the settings FSB Termination Voltage and PLL Voltage, which may be useful in breaking up processors with a significant increase in the frequency FSB. Also, ASUS Blitz Extreme flexibility and the ability to please the memory controller configuration, its capacity in this respect do not concede ASUS P5K Deluxe.
Individual attention paid ASUS engineers food processor system. The fee is equipped with a CPU vosmikanalnym converter food collected at high frequency MOSFET. In addition, the stabilizer can gladden nutrition Loadline Calibration function, which allows to get rid of unpleasant for DFI Vdroop effect - at the CPU voltage drop while increasing its load. Also, ASUS Blitz Extreme and has another unique feature - dual stabilizer feeding memory, which should positively affect the dispersal DDR3 SDRAM.
Note that ASUS Blitz Extreme and has other interesting features, in particular, external HD audiomodulem SupremeFX II, the opportunity to connect to the water cooling system of heat from the chipset, additional diagnostic LCD screen, a large number of information LEDs on the board and more. However, all these "chips" will remain outside the current review, as well as their influence on the characteristics overklokerskie minimal fee.
As of RAM in our system used new DDR3 SDRAM modules from the company OCZ able to work with the frequency of up to 1800 MHz.
Set Memory OCZ DDR3 PC3-14400 Platinum Edition includes two modules of capacity to 1 Gbaytu each designed to work at a frequency of 1800 MHz taymingami 8-8-8-24 with the supply voltage 1.95 V. It is natural that these modules used in its basis Gigabit new DDR3 chips from Micron.
It should be noted that the entire potential OCZ DDR3 PC3-14400 Platinum Edition disclosed when the FSB 450 MHz and use younger divisor for Intel P35 FSB: DRAM equal to 1:2. That allowed us to deal with acceleration test processors, not looking at the parameters of memory.
For the dissipation of heat from the processor, we used time-tested cooler Scythe Infinity. To set a pair of high-speed (about 1900 RPM) 120 - millimetre fans (at vduv and blowing), the cooler can rightly regarded as one of the most efficient air cooling systems.
