Eyeing NVIDIA's Lunch: AMD's New Chipsets
Details were scarce about the upcoming RS700 chipset other than the fact it will support DX10 graphics capabilities and include support for HT 3.0, PCI-E GenII, 45nm CPUs, and Avivo HD. This chipset will replace the somewhat successful AMD 690g/V in the low end market in the middle part of next year.
With new CPUs come new chipsets, and thankfully this part of the discussion will happen in the near term. By the end of this year, AMD will introduce its RD790 chipset, which AMD hopes will be competitive with NVIDIA's Socket-AM2 solutions.
The RD790 will obviously support Phenom, but it will also support what AMD is calling CrossFire 2.0. This enhanced multi-GPU spec will support up to four GPUs working in tandem, although we're not clear what GPUs will be supported in this mode or when. Not to mention whether or not we'll run into the same problems we did with NVIDIA's Quad-SLI and performance.
PCI Express 2.0 will also be supported by the RD790 chipset, which doubles bandwidth and dramatically reduces latency to PCIe 2.0 compliant devices. Backwards compatibility with PCIe 1.0 devices is maintained. The chipset will support 32 lanes for graphics (either in 4 x8 slots or 2 x16 slots), 6 x1 lanes for expansion and a single x4 lane to connect to the South Bridge.

What the heck are RDDR and UDDR? My only guess is the U might stand for the UMA design, but I don't know if that would be preferred for the server or workstation.Anand Lal Shimpi - Tuesday, July 31, 2007 - link
RDDR = Registered DDRUDDR = Unbuffered DDR
Take care,
Anand

Ok, what is OoO? I couldn't find it with a search on Google.Spartan Niner - Saturday, August 4, 2007 - link
OoO is "out-of-order" referring to OoOE, "out-of-order-execution"http://en.wikipedia.org/wiki/Out_of_order_executio...">http://en.wikipedia.org/wiki/Out_of_order_executio...

This is the best future roadmap article I have ever read. I am actually excited. No really.najames - Friday, July 27, 2007 - link
I am an AMD fanboy, of 7 computers I have at home, only the 5 year old laptop has an Intel chip now. Dual cores are actually likely all I REALLY need. That said, I am sick of a bunch of hype and no new products. It's all blow and no show. I don't care about years down the road because it could all change between now and then.AMD/ATI could be a good thing too if they make good, polished drivers, 100% working for what was promised. How about throwing people a bone to make them switch, maybe even make some kick butt Linux drivers too.
We were all on an AMD bus and nobody has been driving since the X2 chip. They taunted Intel and handed out huge bonuses, but forgot about any new development. I have to credit Intel, they kicked butt with Core 2, and seem to be doing more butt kicking going forward.
I watched Hector on CNBC last night and he didn't look like he had a clue what was going on. Granted they weren't asking him details of any processors, but he was dodging basic business questions. Why do I have several hundred shares of AMD?

Because those relatively cheap shares, compared to Intel's, might be worth hundreds of times more one day from that stuff you call blow. Blow = prospects in business terms.
I would say the same thing as you did though at first. It's obvious AMD and ATi's pipeline dried up and unfortunately both consecutively. You can argue that the 2900XT is a good card, performs well, etc..etc.. but that doesn't explain why AMD offers crapware for main stream (where the real money is). As for AMD's CPU line up...well..you can only sell old for so long in the technology sector without taking a hit.

.... dump ATi. The marriage made in hell. New products unable to meet schedule and with inferior performance, thus no way of rapidly recovering development costs by pricing for performance.Dave Orton sure did a neat sell-job on AMD, walking away with $$millions when AMD paid a 20% premium for a chronically non-performing company barely managing to eke out some tiny profits during the last couple of years. No wonder Mr. Orton was finally shown the door.

What is the problem with AMD, did they not receive enough feedback that UVD is a "must have" on high end units. I don't want to have choose between good gaming performance and movie performance... I am paying a ridiculous premium already for hardware... the least they could do is make sure it has all the bells and whistles.
