AM3 Reference Diagram Disclosed 65
psyph3r writes "Chilehardware has released what appears to be a confidential image showing the future customer desktop AM3 reference boards for AMD and ATI. Here is an English site talking about this reference design image and the features it enables. 'The biggest improvement for this generation of chipsets is the audio and video capabilities integrated into the motherboard. The new features packed into these chipsets are beginning to look like standalone platforms. The RS780 supports DirectX 10 and has a UVD, which is similar to most High-end cards of today.'"

Supporting DirectX 10 and all that is great and all, but, how fast will it be? I remember getting an nForce 4 integrated video board for my folks some time ago and it supported the latest DirectX versions and, while it ran all the nVidia eyecandy demos, it sure was slow.
I mean, TFA makes reference to Hypertransport 3.0 and all, but memory bandwidth is only part of pretty pixels.

Good point.
I think most of us are hoping that the marriage between AMD and ATI allows them to produce chipsets with actually decent graphics performance. Maybe not on par with a standalone GPU, but I'm hoping it at least approaches that...
Even if its barely adequate, a decently performing system that allows me to use my HDTV as the monitor would be a welcome improvement.

There is the problem. If someone were willing to put a lot of money into a motherboard just because of the good graphics card on it, they are most likely the kind of person who is willing to put in a lot of money into a new video card in a year or so. Which means that now their expensive motherboard w/ GPU was a stupid purchase, since they could have started with a regular mobo and separate

I haven't noticed that. What I've seen is that usually games will reach a plateau for a while (maybe a plateau with a slight incline) and then suddenly jump forward. For example, Doom 3 and Half Life 2 were both released withing a few months of each other, and Unreal Tournament 2004 was released only a few months before Doom 3 (UT2k4 required enough of a boost over UT2k3 that I included it).

In the case of Intel, it's the memory bandwidth coupled with a distinct lack of Vertex Shader support.
In the case of AMD, it's the memory bandwidth coupled with a dramatically reduced/nonexistent support for Vertex Shaders.
In the case of NVidia, it's the memory bandwidth.
In the case with many IGPs, the combination of having to share RAM with the machine on it's own bus, along with no Transform, Clipping, and Lighting hardware acceleration (Little to no Vertex Shader hardware...) means for a very slow GPU overall. Now, having said this, the Hypertransport 3.0 interface may help on the bus speed, and if you're looking at the Unified Shader requirements for DX10, you might find that this may be a little better performer. It's not going to be like a PCI-E add-in card, but it may be serviceable for light to medium duty 3D stuff by itself because of those two things.

In the case of the discrete cards (PCI-E, AGP...) they have a pool of memory that's accessible via the bus and that's directly accessible by the GPU's own memory bus (That memory size when you see 128, 256, 512Mb, etc.)- which is faster than just about anything out there and has no contention spots for the GPU to have to wait any longer than the access latency to the memory from the second access port. The peak speed of the GPUs when compared to an IGP solution comes from the contention-less, very, very fast access to the card's memory pool so that you don't stall the graphics pipeline. A stall of a microsecond can cost you FPS (Duh...) and larger stalls can drag framerates to the slide show domain- it's part of why the older ATI fglrx drivers were roughly 50% slower under Linux when compared to Windows. They had a stall in there somewhere that was introduced by their way of getting their then Windows-ish codebase to work under Linux.
Now, having said this, Hypertransport's suspiciously close to the same performance level of most of the local GPU buses and you only need to deal with bus contention issues for the only real performance snag. IGPs start making sense at that point for many applications because the memory's now close to the same speed as the add-in card's memory with similar latencies. The only real slowdown would be that you don't have dual pathways now.

As for PCIe vs. HT, they're probably so similar in latency and throughput at that level that its just a difference in transistor count or something similarly insignificant.

That's plenty of 2.0, and even some 1.1's for devices that you don't want slowing down the 2.0 bus.

Is that really so hard? Integrated video is easy enough to avoid, but you just can't get a motherboard these days that doesn't have onboard audio. I'm sick of having to disable it whenever I get a new board, and the amount of space the jacks take up on the rear panel could be better used for more USB or Firewire ports.
I use an old Soundblaster Audigy for my sound needs, and it does everything I need. In hardware. Every time I buy a new motherboard, I test the onboard audio first, just to see if it's gotten any better than I last tried it.
So far, this card's lasted me four complete system overhauls, and at this rate, will last until a version of Windows comes out that where Creative don't release drivers for it.

also note that you need a control panel to set the spdif output.
also also note (also also wik?) that you need to know the diff between 5v output and 0.5v output. 5v is used to drive opto blocks (toslink thingies). 0.5v is used to drive 'coax' output (rg style 75ohm coax). sending 5v to the coax out may overdrive your home stereo. sending 0.5v to the opto block will give you a whole lotta dialtone (ie, no audio out).
