VIA KT333 Based Mainboards Roundup

Recently we tested a second lot of the VIA KT333 based boards. Today we are going to close the subject with 5 more boards thanks to the combination of the KT333 north bridge and VT8235 south bridge. Besides, as many our readers are interested mostly in speed we will add the fastest models from the two earlier parts. It will let us find out the fastest VIA based mainboard for the Socket 462 (see the review of the chipset).

Test results

The MPEG4 didn't reveal the difference between the new boards, the leader of the second part Abit KX7-333R thrives here as well - it outscores its closest competitors by 4%, and losers by 6%. 

The WinAce archiving gives close scores making the difference a bit clearer. The speed of the Abit KX7-333R is higher by 9% as compared with the outsiders FIC and Soyo. However, in the WinAce the Gigabyte comes very close to the leader - it lags behind only by 2%, and the Chaintech and Shuttle are also just a couple of percents behind the second position. Well, the last winners - Abit and Gigabyte turn out to be the most efficient boards here as they exchange data with the memory most intensively. 

In the SYSmark 2002 the memory throughput is not the most vital factor in the test. Here we have new leaders - Chaintech and Shuttle (their results are almost identical in all tests). The Gigabyte is 2% behind, and the Abit doesn't shine in the business tests - you might see it in the last tests (probably because of the worst organization of the hard disc access). The outsiders do not change: FIC and Soyo. 

In the 3DMark working in high resolutions the difference between the participants is almost unnoticeable - those who work better with the memory have better scores, the Gigabyte is ahead this time. The layout of the new-comers remains the same. 

The victory of the Chaintech tangles the situation, especially considering quite low results of the Abit. The different between the fastest and slowest boards is less than 5%. 


Well, it's quite complicated to single out a leader. Different groups of the tests reveal different winners; still, giving credit to the Abit KX7-333R for the best scores in the memory-intensive tests and and to the Chaintech 7VJL and Shuttle AK35GT2R for their stably high marks, I should admit that the Gigabyte 7VRXP is the most efficient model. It's interesting that it was the first model on this chipset that arrived in our lab. 

Do remember that the difference of a couple of percents should be a determining factor when choosing a board. First of all, turn your attention to the table with brief characteristics of the board. Having chosen the most interesting and suitable for your tasks models go to their description, and then, taking into account accessories, functions and speed you should account for the price.
