In earlier published articles some main problems and tendencies of development of modern chip sets and motherboards have been considered. Strengthening of positions of the small, dynamically developing corporations which products in many cases make a worthy competition of similar production of the eminent and deserved computer corporations which reachings are widely presented in the domestic market was thus marked. Thus products of young corporations are quite often characterised not only rather low prices, but also rather quite good parametres doing them attractive to usage as a part of modern computers.

In previous article some variants of motherboards from wide gamma of products of Jetway corporation which production, considering the concluded contracts, applies have been in detail described to occupy a place of honour among the accessories calculated for usage in arrangements, intended for the mass user.

Declared technical parametres and functionality of the resulted cards allow to consider the given possibility seriously. Especially if also productivity of the systems created on the basis of these units, appears at worthy level — level corresponding, at least, to products of the given price category.

Before the resulted cards of Jetway corporation the substance presented more low received in the course of careful testing of specified products also will be devoted an estimation of productivity.

Before to pass to the received results, it is necessary to remind a number of known positions and some technical details of products and the units participating in testing.

It is obvious, that the computer power analysis should be led on the basis of usage of the widespread and standard tests estimating both technical possibilities of separate components, and all system of the computer taking into account software influence, including the operating system and widespread program applications. Such approach, as a rule, allows to minimise the negative consequences linked quite often with the subjective approach to an estimation of analysable means.

It is necessary to take also into consideration, that the received numerical estimations, as a rule, are clear only to a narrow circle of experts. However their analysis is facilitated, if in the course of testing as the measurement standard other similar products use. Usually they are constructed on the basis of the same units or, at least, the units possessing in similar parametres. It is better, if standard products concern group of widespread products of known corporations. Then, comparing the numerical estimations received in results of testing, as a rule, become clear to a wide range of users, and not just separate experts.

Considering possibilities of motherboards, it is necessary to remind, that their architecture and functionality basically are defined by type of the applied chip sets which are a basis of construction of modern cards. As a rule, the existing chip sets used as a part of motherboards, are presented by two chips — North Bridge (Northern bridge) and South Bridge (the Southern bridge). Thus for effective operation of the central processor unit, dynamic storage and the videoadapter chip North Bridge, and for communication facilities with peripheral devices which ROM, the keyboard and the mouse, the built in resources of sound functions, the modem, a local area network etc. concern hard and floppy disks, CD and DVD responds ., — South Bridge. Quite often this chip contains controls for computer functional modes, for example, modes energopotreblenija.

The chips which are a part of chip sets, through the motherboard architecture substantially define functionality and productivity of all system of the computer. Well, and it is finite, it is impossible to forget about such important parametres of motherboards, as quantity of DIMM slots defining number of units and sizes of dynamic storage, supported modes AGP and protocols of operation of disk drives, quantity of PCI slots and ISA, ports USB etc . Besides, great value such possibilities as play the built in audiofunctions and hardware monitoring, controls for power supply etc .
