Socket-A Chipset Roundup
EconolineCrush writes: "The Tech Report has a review up of VIA's new KT333 Socket A chipset. Though it's really a review of the KT333, a total of seven different chipsets from VIA, SiS, AMD, and NVIDIA are compared to determine the uniprocessor Socket A performance king. This is definitely worth checking out if you're in the market for an AMD platform, or are curious to see how your current chipset stacks up against the latest and greatest."
Tom's Hardware has a good article up.
"A total of 26 various benchmark tests clearly shows that the VIA KT333 chipset the best and most capable chipset for AMD CPUs. With only a few exceptions, not even the Nvidia nForce with its expensive dual-channel technology (DDR266) can put up a real fight against the newcomer KT333. With the launch of the KT333, the KT266A will become a thing of the past - you simply won't want to miss out on all the new features such as ATA/133, USB 2.0 or DDR333 support."
So does Anandtech: here.
"When the KT266A was launched it completely blew us away; the performance of the chipset was spectacular and it was clear that it would quickly become a top pick for all Athlon owners. The KT333 doesn't have nearly as great of an impact but the reasons behind that are understandable; both new features supported by the chipset, DDR333 and Ultra ATA 133 aren't features that will result in tangible improvements in performance today. Instead the KT333 is more of a technology enabling platform for VIA. The chipset will not cost any more to manufacture than the KT266A and thus motherboards won't increase in price. While DDR333 SDRAM isn't officially available today (the specification isn't complete), when it is first made available it will carry a price premium over DDR266 SDRAM."
The Tyan Tiger MP kicks ass, IMHO. (AMD 760MP chipset). I've been running it since December, never crashed (from hardware, anyway. :-) One note with this board, be sure to get a *heavy-duty* power supply. My SMP box has an Enermax EG651P-VE-something or other (550W), which works *very* well (but is kind of expensive).
Be sure to stay away from the AMD 760MPX chipset (note the X) until early March, because on the current revision, *USB doesn't work at all on the Southbridge* (although I've heard vendors are shipping USB 2.0 cards to get around this problem, but do you really want to lose a PCI slot?)

I find it amusing how Tom's always reduces things to frames per second in Quake3. As if that's the best measure of performance for any component of a system.
I imagine in the future, manufacturers, instead of listing [MHz, drive speed, etc], will list modifiers to Quake3 FPS. ie- specs on a system of the future will read like a Dungeons & Dragons character sheet:
Bob's Machine of 3l33t Gaming
CPU of giant GHZ: +100 FPS
Elven Motherboard: +5 FPS
GPU of Rendering: +80 FPS
Cursed Hard drive:-15 FPS
magic DDR memory: +20 FPS
ISA SB16: -20 FPS
-----------------
Save vs Quake3: 170 FPS
After assembling a new system consisting of an Antec case, Soyo Dragon Plus motheboard, 1GB Corsair DDR RAM, XP 1800+ CPU, 64MB GeForce 2 Ti, Sound Blaster Audigy, Yamaha CD-RW and Adaptec 2930 SCSI card (Notice the lack of cheap components), I've discovered that the VIA chipsets and Nvidia videocards have a history of not getting along, with all fingers pointing at the KT266A chipset.
Running Win2K Pro (fully updated), and the latest BIOS and drivers for everything, and not overclocking a darn thing, I'm still suffering random system lockups doing simple activites such as broswing the web. Games are too tempermental to seriously play. (It was really bad before I uninstalled the latest MS win2K rollup update - click on any browser link and have a 15% chance of the system hanging...)
I bought the Dragon Plus Motherboard based on all the wonderful online reviews of the board and chipset. Not one said anything about the lack of stability with the KT266A chipset, or any problems with lockups. Later, doing some google searching turned up message boards full of other people experiencing the exact same problems. The only "solution" discovered (and even recommended on the Soyo web site) is to drop the RAM/Bus speed to 100Mhz from 133Mhz. That kind of defeats the purpose of making a fast machine...
Now I'm trying to research a motherboard replacment (which means resintalling the OS and most software - shoot an afternoon there) based on stability first, then performance. I'm thinking nForce, but we'll see...
It's a shame to waste the money on motherboard I'm going to throw out, but there wasn't a warning to be found when I did my initial research. (Note to self: Use google more for these kinds of things)
