In this test, we take a look at the performance of the 4 integrated graphics chipsets, AMD 690G/SB600 vs SIS 771/966 vs NF 6100/410 vs ATi RS485/SB460 in its USB performance with an external HDD in Vantec enclosure connected via USB cable.

AMD SB600 scored 26MB/s, SiS 966 scored 26MB/s while NV 410 scored 19MB/s and ATi SB460 scored 16MB/s. Both southbridges from AMD and SIS are equally fast. A yr ago, we tested ICH7, it only scored 25 MB/s. The two other south bridges are really old and only performed below 20MB/s.
