FIRST LOOK: ULi M1697 for Athlon 64/x2

Audio Performance
For audio testing, we used Rightmark 3D Sound CPU utilization test, which is the same benchmark run in our earlier nForce4 SLI and Ultra roundups. This benchmark measures the overhead or CPU utilization required by a codec or hardware audio chip. We tested performance using the latest version 2.1. Since we found that Version 2.1 yields different results from the earlier 1.24, we have only included test results with version 2.1.
It is important to point out that the latest ULi and ATI chipset motherboards have the necessary hooks to deliver Azalia High Definition audio. Those who have been complaining about the poor AC'97 audio present on most AMD boards should be very pleased to find Azalia HD on the ULi and ATI chipset boards. The nForce4 family does not offer the necessary chipset hooks to support HD Azalia audio.
Ethernet Performance
The one area where the ULi M1697 is disappointing is in their choice of an ethernet controller. Instead of using a Gigabit LAN, ULi only provided chipset support for a 10/100 Ethernet PHY. In practical terms, 10/100 is plenty of speed for most broadband connections, but with Ethernet quickly becoming the new standard, it is mildly disappointing that ULi still does not support Gigabit Ethernet on their chipsets. This is undoubtedly a cost-saving measure, but it mars an otherwise excellent AMD chipset.
Manufacturers can still implement Gigabit Ethernet with discrete chips, but it is more difficult to provide that solution on the preferred PCIe bus when there are no hooks for Gigabit PCIe in the chipset. Since most broadband ethernet connections barely tax 10Mb/s, this will really only matter to those who do sustained high-speed transfer of very large files over a true Gigabit network. Still, you should be aware that PCIe Gigabit Ethernet is always a better solution, and competitors are providing that capability in their current chipsets.

I presumed that ULI provided Anandtech with the sample to review... if you think about it, there are some wierd angles on that... A big deal like that isn't hammered out in a couple of days. ULI "brass" knew the sale was coming.It's kind of wierd, IMO, to send out stuff for reviews as you're going under.
I suspect that nVidia will sit on any tech they acquire, and not implement it. I was sorely disappointed that they sat on the GigaPixel technology a few years back, and there was of course more from the 3dfx acquisition that they never implemented.

Too bad this chipset is doomed before it even gets implemented LOL!http://www.nvidia.com/object/IO_28250.html">LinkPuddleglum - Wednesday, December 14, 2005 - link

Bad link on above post. You can read about Nvidia buying out ULi http://www.theinquirer.net/?article=28333">hereIRQ Conflict - Wednesday, December 14, 2005 - link
wierd, it was working yesterday? Oh well nVidia's following M$'s lead again. I can still smell the embers of the 3dfx acquasition.Peter - Tuesday, December 13, 2005 - link
And yet again, we're seeing Anandtech experts (?) evaluate the RAM controller properties of an AMD64 chipset.Hello?
The RAM controller is in the CPU, folks. Time to acknowledge that and skip that step in a chipset review.

Peter, this is what you were referencing:I don't see the words "controller" or "chipset" in there, and yet you say that the article evaluates the RAM controller properties of the chipsets. What he said about the lack of memory voltage adjustments was not referencing the chipset, but the method that Anandtech uses to overclock their boards.How did you come to think that the article mentioned the RAM controller?

I'm referring to the following statements on page 4:>Memory Stress Testing: Since this is a new chipset, the best setting for tRAS was first determined.
>This means that any setting from 6 to 11 tRAS will work well with this chipset.
>*7T was determined by MemTest86 benchmarks to deliver the widest bandwidth with the ULi M1697 chipset.
For anyone who's looked at the block diagram on page 2, it should be bleeding obvious that the RAM isn't the chipset's business at all.

Uhhhhh... havent used many A64 boards lately? ;) The ability to run low latency timings is very highly regulated by the board and chipset. You cant just drop any stick of ram in any board and get identical timings.The memory controller may be on the chip itself, but this doesnt eliminate the board and chipset from the equation whatsoever.

AMD64 architecture totally eliminates the chipset from anything that is even remotely to do with the RAM bus. That's the point, and you're not getting it either.
