A Closer Look at SiS755
SiS755 is compatible with either Athlon64 or Opteron/Athlon64FX. The Reference Board is an Athlon64 board supporting Socket 754 A64 chips. Our reference board combined the 755 Northbridge with the 964 Southbridge, which adds many contemporary features.
While the 755 can also be combined with the older 963L Southbridge — a combination you will see on cheaper solutions — the most competitive features are provided when the 964 is used. The 964 adds SATA RAID, increases USB ports to 8, and adds base code for “Hollywood Audio”-10/100 Ethernet-Modem.

SiS seems to be a contender with this chipset. Hopefully the Final shipping boards exhibit similar performance.I think this also lays to rest the idea that all Athlon64/FX chipsets will perform equally because of the onchip memory controller.

#1-We agree, and that feature is supposed to be available in the next version of our Graphing Engine. There is no current option to use different colors on single-set graphs. Before anyone asks again, the decision to use Flash for charts was because flash uses less bandwidth than any other option. On a site like AnandTech with very heavy traffic, bandwidth matters a great deal. We do not, as Editors, have the option to use other methods for charting.#2-While we have not found a difference in performance in our benchmarks, some claim the nForce3-150 use of 600HT/8-bit instead of the specified 800HT/16-bit DOES hamper performance in some demanding applications. nVidia is fixing this in the nForce3-250 and claim they will also provide 800HT/16-bit. It is expected that future Athlon64 chips will run at even higher HT speeds. As stated in the review, SiS calims 1000HT speed for their new 755FX for Socket 939FX.
Even if we ignore the impact of Hyper-Transport speed, the SiS755 outperformed both nF3-150 and K8T800 in virtually every benchmark we ran. SiS755 also provides SATA RAID and 8 USB 2.0 - features missing from nF3-150. While we did not publish the IDE bandwidth tests, it is well-known that SiS has the best IDE controller and the 755 does perform better in IDE tests than either nVidia (2nd) or VIA (last).

Ok, maybe I haven't been keeping up with my A64 literature; but what is so important about being able to run at HT800, as opposed to 600? If the nForce3-150 performs on par with everything else, and can still use PC3200 memory like everything else, what's the problem?Basse - Monday, November 24, 2003 - link
Again, why not use a different color for the tested item in the graphs?Otherwise, nice review :-)

SiS make stellar chipsets, as far back as my days in 486 computing always had great experiences with them, very fast reliable and cool running.inoncuppobmip - Tuesday, September 15, 2020 - link
