Mathematically, x8/x8/x8/x8 should be able to sustain four R9-290Xs up to 4k resolution 32-bit color at 60FPS before starving to death. HT will need to be overclocked significantly.

At 1600p or lower, the risk should be minimal and may even allow for 90-100FPS, though due to the extra data sent to the GPUs scaling in such a way would not be optimal.

Quote:
HRes * VRes * CBit * FPS * (Cards - 1)
______________________________

8 * 1024 * 1024 * Cards


^ Amount of bandwidth the lead GPU will need to have available for frame transfer.

At 4k 32-bit 60FPS, the lead GPU will need to be able to receive 1,424 Megabytes of data per second from the other three GPUs. At x8, this leaves it with only 2,672 MB/s of bandwidth for frames form the CPU and bus overhead. It then has to process the data from the CPU and get it out the door in time to be used.

Each of the other three GPUs only needs 475MB/s of bandwidth to transfer to the lead GPU. all of those are fine. However, 2.0 x4 is considered a no-no for GPU usage, and that is cutting it very very close giving the lead GPU only an x5 to deal with.

At a lower resolution such as 1440p, the bandwidth needed for transfers from the other GPUs is cut in half, giving the card much more headroom (~6.5 lanes). However, if the FPS is increased over 60, both the CPU -> GPU and GPU -> GPU bandwidth scales linearly, quickly cutting off remaining supply before it can double.

This basically limits the situation where you would want Quadfire 290Xs in the first place (4k and above) by the PCI-e buss simply not being able to do it. Trifire at x16/x8/x8 would actually be much better suited, or even using a Dual GPU card (not that they exist) to conserve some precious bandwidth.

My two cents. Be very very careful, because the lack of crossfire connector is actually going to hurt here. That extra .9GB/s would have tipped the scales. There is a reason AMD recommends 2.0 x16 and 3.0 x8.

x8@2.0 on the main card would be enough for even 4K@120FPS in framebuffer, however, this doesn't include extra shader buffers, 4-channel float buffers for example take 4 times the size compared to a normal RGBA buffer.

Sure, if you completely ignore that the CPU needs to transfer data to the GPU for the GPU to do work.

Even 2.0 x4 starts to limit the card. 4K at 120FPS would leave just 1GB/s, half of which would be overhead. No where near enough.

pretty much, I would expect a massive HT overclock to be needed though before the PCIe would become a bottleneck, NB would probably want to be under water, but we're just going to have to wait and see how it turns out and how far Red can push it.

as a side note though; in most normal rendering with shaders (HSL (DX) or GLSL (GL)), performing a normal frame render just involves sending uniform variables into the shaders which you already would have loaded in the GPU memory, alongside all your needed meshes and textures, its mostly "pointer" (ID) based, in single-GPU setups you don't have to worry about PCIe either as any buffers used (in deferred rendering for example, almost every game uses this) are already in the GPU's memory, multi-GPU however, depending on the type of buffer, synchronization may be required which will eat at your PCIe alongside the frontbuffer transfers.

this is where driver optimization becomes apparent depending on the game, a lot of cases you can do without the synchronization on most of the buffers, if not all of them, and uniform updates are almost always less then 1MB in size, in theory it should still all work fine without bottlenecking, but you cant be sure with these things without testing.

might even whip up a little tool to stress buffer feedback in shaders, I'm very curious how this will all turn out as we're not even including GPGPU tasks that some games use for AI etc.

No actually.

HT is the link between the CPU and the NB. While that actually would normally be a bottleneck for Quadfire, due to the massive inter-card bandwidth the PCI-e bus is the first bottleneck by a long shot. Overclocking HT will not allow him to run any higher resolutions or higher FPS. PCI-e also can not be overclocked beyond maybe 105 since the SB chip along with the SATA controller are both on the PCI-e bus, and thus extremely prone to corruption.

At 1080p HT may be a bottleneck. But you do not run Quadfire 290X at 1080p.

so the drivers/cards DO have the ability to communicate directly to each other over the NB? I haven't had the chance lately to really look at that so as far as I know it still needs a lot of CPU action, but if this is true then we have no real bottleneck to worry about provided the NB is clocked fast enough...

While that actually would normally be a bottleneck for Quadfire, due to the massive inter-card bandwidth the PCI-e bus is the first bottleneck by a long shot. Overclocking HT will not allow him to run any higher resolutions or higher FPS. PCI-e also can not be overclocked beyond maybe 105 since the SB chip along with the SATA controller are both on the PCI-e bus, and thus extremely prone to corruption.

At 1080p HT may be a bottleneck. But you do not run Quadfire 290X at 1080p.

so the drivers/cards DO have the ability to communicate directly to each other over the NB? I haven't had the chance lately to really look at that so as far as I know it still needs a lot of CPU action, but if this is true then we have no real bottleneck to worry about provided the NB is clocked fast enough...

The PCI-e controller is a massive switch, complete with addressing. The cards may not communicate Card -> Card, but they can communicate Card -> Controller -> Card. This is why PLX chips work, and is the basis for XDMA. Note the 2nd point;



The card may tell the Driver that it's done and ask where to send the frame, and the driver may respond with a PCI-e address, but that's about the end of it.

And again no, x8/x8/x8/x8 will still be a huge bottleneck because you can not overclock the northbridge.

What you can overclock;
CPU
RAM
HyperTransport
PCI-e Bus
CPU/NB

CPU/NB is the link between CPU, RAM, and Cache. HT is the link between CPU and physical NB. PCI-e bus is the link between physical NB and PCI-e devices and the SB. You can not overclock the PCI-e bus without extreme risk of data corruption since literally every data source you could want is off the PCI-e bus in some way. Overclocking the PCI-e bus is the only way to make more bandwidth available to the GPUs without either adding more lanes or upgrading them to 3.0.

that's what I forgot about, this shader programming lately has screwed with my memory doh.gif

the crosshariV I'm pretty sure had the ability to modify NB clock, unless that's actually referring to the CPU-NB and is incorrectly labeled as such...

PCIe bus *can* be OC-ed a bit though without problems, I had 110 running on mine for a bit, but that's about as far as you can usually go and doesn't exactly gain much, but I guess that's for Red to try and see if it changes results. but 120 is definitely a no-go unless you wanted to go without (or kill completely) your LAN, USB3.0 and extra SATA, most GPUs don't even work that high.
