Sapphire PURE Innovation - ATI's Chipset for the AMD Enthusiast

Ethernet Performance
The new motherboard test suite, launched earlier this year, includes LAN performance measurements. The test procedure that we use was first described in a VIA white paper.The Windows 2000 Driver Development Kit (DDK) includes a useful LAN testing utility called NTttcp. We used the NTttcp tool to test Ethernet throughput and the CPU utilization of the various Ethernet Controllers used on the nForce4 Ultra motherboards.
We set up one machine as the server; in this case, an Intel box with an Intel CSA Gigabit LAN connection. Intel CSA has a reputation for providing fast throughput and this seemed to be a reasonable choice to serve our Gigabit LAN clients. At the server side, we used the following Command Line as suggested by the VIA whitepaper on LAN testing:
Nttcps - m 4,0,On the client side (the motherboard under test), we used the following Command Line:-a 4 - l 256000 - n 30000
Nttcpr - m 4,0,At the conclusion of the test, we captured the throughput and CPU utilization figures from the client screen.-a 4 - l 256000 - n 30000
CPU utilization measurements for Gigabit Ethernet can be somewhat misleading, since they measure the percentage of CPU tie-up at sustained Gigabit receiving. In reality, it would be very rare that you would actually see sustained Gigabit transmission levels on your PC. For that reason, you should put the measured CPU utilization of Gigabit PCIe LAN in perspective. It will almost always be much lower than what we have measured.

One of the big things for me is that there is only passive cooling on the motherboard without the need for crazy heatpipes etc. This is really important for those of us who want to build silent computers.I'v definately picking up this board from Saphire.

Good point must run at lower temp than nvidia's single chipset solution which gets hot as hell when you start cranking HTT.rjm55 - Friday, July 29, 2005 - link
We mentioned several times in the article that Sapphire will launch the new board in early August. Sapphire has confirmed their plans to launch around August 5. Sapphire has asked us to pass on that you will be able to buy retail PI-A9RX480 motherboards in most markets by August 15th-20th. Price will be "competetive with nForce4".Resh - Friday, July 29, 2005 - link
Any idea on when we will see them? I'd really like to go that route, but I can't wait forever!Wesley Fink - Friday, July 29, 2005 - link
Halibut (Crossfire AMD) and Stingray (Crossfire Intel) boards are ready to go to reviewers, but there are still some decisions being made at ATI. We have also seen the prototype retail boards from Gigabyte and another manufacturer. When ATI decides whether Crossfire will be now or with R520 (just a guess at events) Crossfire will roll out quickly.Resh - Friday, July 29, 2005 - link
Thansk Wesley. I wish they would hurry up with that decision... RAM is ordered and PSU, CPU, and X800XL will be ordered this w/e, too, so they better get the motherboards out!If you do hear something, please share it with the rest of us.

wow the white pcb stands out, at least the thing is packaged wellDhaval00 - Friday, July 29, 2005 - link
A week ago, AT was having fun posting such rumors... I am sure it thinks otherwise now :)./me feels like getting rid of all my nVIDIA hardware.

Typo on Pg8, second bottom paragraph. "ATI X350XT PE" - the '3' should be an '8' me thinks.Tommouse - Friday, July 29, 2005 - link
Nice board. Still undecided on the white color though.I wonder if the Zalman CNPS7700-Cu will fit :|
