In previous articles some tendencies of development and the main features of some widespread chip sets have been is short parsed. In particular, variants of popular chip set VIA Apollo Pro133A of VIA corporation (VIA Technologies), oriented to systems with processors of Intel of Pentium II/III and the wide frequency band of bus FSB calculated for usage, as traditional frequencies of 66 and 100 MHz, and frequencies of 133 MHz which gains the increasing distribution in case of usage of the newest high-powered processors have been resulted and described  .

VIA corporation chip sets (VIA Technologies) have found a wide circulation in motherboards of a different price category. Thus in some cases the good performance level is shown by rather inexpensive products. As an example of similar products motherboard Jetway 994AS-L which results of testing have been resulted earlier can be. A basis of this motherboard is the known and popular chip set VIA Apollo Pro133A presented in the given card by two chips of a high-scale of integration: VT82C694X, fulfilling function North Bridge (Northern bridge), and VT82C596B — South Bridge (the Southern bridge).

The systems created on the basis of considered card Jetway 994AS-L, have shown rather productivity high level. Thus in a number of tests productivity metrics have appeared even above than in case of usage of motherboards from more known manufacturers, and quality of the fourline sound realised by means of a specialised chip, it has appeared rather high.

However, despite high parametres and potential possibilities of chip set VIA Apollo Pro133A, the products grounded on application of less powerful, but rather cheaper chip sets of this corporation continue to be popular. For an example of such chip sets can be VIA Apollo Pro Plus and VIA Apollo Pro133. Their popularity is quite often linked to the thought over design and with excellence of manufacture of the cards which basis are the specified popular chip sets.

The fulfilled architecture and carefulness of design often define productivity high levels. How a rule, quite often aggressive advertising promises, and it expediently to check testing. It was a subject of previous article, it becomes a subject of the present discussion. As it was promised earlier, as the research object cards Jetway will serve: Jetway 993BS, Jetway 993AN.

According to earlier formulated principles as the standard card to which the given products of Jetway corporation were compared, card Chaintech CT-6ATA2 has been selected. Not pressing in its merits and demerits, it is necessary to mark, that this card grounded on usage of chip set VIA Apollo Pro133 (North Bridge — VT82C693A), is a well-known product and uses the deserved popularity. It is often applied as the sample to whom the motherboards created on the basis of specialised sets of system logic VIA Apollo Pro133 are compared. For this reason the given choice is the preferable variant used as the measurement standard in operations of an estimation of metrics of productivity of researched motherboards Jetway 993BS and Jetway 993AN, constructed on the similar chip sets which basis are chips North Bridge — VT82C693 and VT82C693A. In view of the wide circulation of card Chaintech CT-6ATA2 explained by in many respects competently constructed marketing policy of Chaintech corporation, results of testing of researched motherboards in comparison with the given sample interpretations easily give in, and are clear to a wide range of users, and not just separate experts.

As well as in the previous case, the computer power analysis was 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.

Before to result key parametres it is necessary to mark, that in case of motherboards of Jetway corporation the type of a form factor and presence of optional resources have found the reflexion in the name of products: A — form factor ATX, B — form factor BAT (Baby AT), S — presence of audioresources (HSP56 CMI8738/PCI HRTF Audio Com), L — presence of resources of hardware monitoring.

Simultaneous presence on cards of processor Slot 1 plugs and Socket 370 processors of Pentium accepting usage III both with kernel Katmai, and with kernel Coppermine, facilitates a choice of processors and the subsequent upgrade, not resorting to the help of the special adapters which price averages from $6 to $15 depending on their construction. Except these features, the important role the quantity of DIMM slots, possible sizes of the dynamic storage, supported modes AGP and protocols of operation of disk drives, quantity of PCI slots and ISA, ports USB, and also presence of audiofunctions, hardware monitoring plays, controls for power supply etc .
