When you want to buy a computer, the first thing you look at on the data sheet is the name of the processor (CPU English, Central Processing Unit). This small chip, in the common imagination, is regarded as the true engine of the PC over its clock speed (Gigahertz), the higher it will be successful, we believe
.
Decoder mandatory
It is essential not to confuse the frequency of a processor with its performance level. The fault manufacturers who, having, for years, included such frequencies in the denominations of their chips, have suddenly changed their classifications five years ago. Today, they no longer appear explicitly in the names of the CPU. They are replaced by references to each of the two manufacturers, Intel and AMD.
Each of these two founders created a classification of its own. The name of a processor begins with the range to which it belongs: Phenom or Athlon 64 for AMD, Core 2 Duo, Core 2 or Quad Core 2 Extreme for Intel. Then things get complicated. The new chips have two or four Core, and the manufacturers are using this as an argument advanced commercial technology . Thus, Intel appoints Does its Core 2 Duo processors with duelCore, and 2 Quad Core 2 Extreme.
At AMD, the figure following the uppercase X, which determines the number of Core: Athlon 64 X2 for a Duelcore, Phenom X4 for a Quadcore. This was followed by a measure of performance, such as 3800 +, 4400 + and 5600 + for the Athlon 64, 9500 or 9600 for the Phenom.
At Intel, the number is preceded by one or two letters: Q if the chip is to Quadcore, X if it is for the Extreme range (Q and X can be combined), E if it is a model for Desktops, T if it is a processor for laptops. The numbered, it reflects various characteristics such as smoothness of engraving, the amount of memory cache, frequency of buses required, or clock speed. The least we can say is that it is not very explicit ...
The number is increasing at the same time as the clock: the Core 2 Duo E6850 is faster than the Core 2 Duo E6750 (3 GHz to 2.66 GHz ), the Core 2 Extreme QX6700 least as fast Core 2 Extreme QX6800 (2.66 GHz to 2.93 GHz).
Intel, the Almighty
If you have followed, you now know why the letter T does not appear in the names of the Intel processors of this prize: in fact, it only affects models for desktop. More seriously, this information can more readily see the chart above, and to draw some conclusions very helpful before buying.
The first is the number of references to the catalogues of the two founders: 2/3 of those we surveyed match Intel models. The giant Santa-Clara truste also the first places in the field of pure power. With Phenom X4 9600, AMD struggling to climb in the top ten. The trend is completely when calculating the price / performance ratio.
Intel sells then places his head competitor. On top of the table is taken over by the Athlon 64 X2 AMD, the 3800 + provides by far the best report. The latest chips with Quadcore, such as the Phenom AMD and Core 2 Quad Core 2 Extreme and Intel remains, for now, in several price fairly high. But, as always in computing, these processors will see their costs drop in the very near future.
This can be done they become the new standard machines general public. If you need to be equipped, dual-core models of middle and high-end still a sure bet. To bet on the future and the survival of a configuration option "Quad Core" is to consider seriously.
