what if on a mobo there would be a socket for the cpu and another socket for the gpu and the gpu would come as a chip and a heatsink/fan just like any cpu. and there would be slots for ddr1/2/or better memory and gddr/1/2/3/or better memory and the graphics memory would come like system memory sounds stupid....any comments on it

While that may seem like a good idea there are a few things that restrict that. One issue is access to memory. The GPU benefits from having a large amount of memory very close by so it can run at high speeds. The graphics memory is usually ahead of standard RAM. Having a chip only solution would either strain the memory bus or these parts would need to start integrating cache onto the chip.

A graphics processor is essentially a second CPU, except it's used to process graphics. A graphics card is basically a daughter card with an integrated CPU and memory which plugs into a slot on the motherboard.

i think hes striking at the idea of upgradeable builtin components. Peer inside your case, past the lucite window and look at your motherboard. Glance to your videocard and now imagine it melting into your motherboard, and your motherboard growing by about 36 square inches. What do you suppose all those nifty bits and pieces on your videocard are for, and where are they going to go?

It's not a good idea for a couple reasons:

1. Airflow would be poor
2. VIVO, DVI and a slew of other connections would have to be standardized and put on the motherboard. (unless u use a PCI connector plate)
3. GPU's and memory are designed to work together more so than CPU/Memory. In other words, nVidia/ATI put a lot of work into which specific memory chips work best w/ the GPU. If you have DIMM slots on the mobo for the GPU, anyone could make the memory and you'd have performance/compatibility issues.
5. real estate on ATX/BTX motherboards is already slim, there's no room for 2/4 more DIMM slots and a socket for a GPU.
4. there's no technological need for it PCI-E 16x is plenty fast enough and PCI-E 32x is already being worked on. There are no advantages to your idea.

Nevertheless, it was an interesting one.

I'm not advocating a socketed GPU just yet, but will play devil's advocate for fun:

1. Airflow would be poor

Workarounds wouldn't have to be all that difficult. It's not like GPU HSFs are the most elegant solution imagineable.

2. VIVO, DVI and a slew of other connections would have to be standardized and put on the motherboard. (unless u use a PCI connector plate)

AMD might have chosen 4x4 to bring RHT and to be first to set a GPU socket standard.

3. GPU's and memory are designed to work together more so than CPU/Memory. In other words, nVidia/ATI put a lot of work into which specific memory chips work best w/ the GPU. If you have DIMM slots on the mobo for the GPU, anyone could make the memory and you'd have performance/compatibility issues.

So sell the DIMM with the socketed GPU or put the memory on-die.

5. real estate on ATX/BTX motherboards is already slim, there's no room for 2/4 more DIMM slots and a socket for a GPU.

Is there a need for more than one DIMM slot ? You don't need more than 256 or 512 MB do you? Maybe a new kind of compact slot? How about a 256 or 512 chip or chip array on the mobo? I'm not claiming this will work, just asking if it is feasible.

4. there's no technological need for it PCI-E 16x is plenty fast enough and PCI-E 32x is already being worked on. There are no advantages to your idea.

What if AMD has bought into Physix in a big way and are looking to have a more efficient means of CPU to GPU to PCP communication? Again, I'm just asking questions. Clearly, increasing GPU clock and graphics memory speed is of interest. If graphics memory capacity or speed is decoupled from the GPU, maybe that is considered an advantage by ATI or AMD? Each time I think about 4x4, I wonder if AMD has been collectively drinking too much or if they actually have something really cool headed down the pipe. It's hard for me to accept that they lost the ability to find intelligent solutions.

What do you think 4x4 is? There is no special hardware except for a desktop motherboard that supports dual processors. This is already the standard in the server market. And 4x4 will not have RHT! It will have 2 sockets, and therefor RHT is not possible unless it is done in software, and in this case, it would be possible on Intel CPUs too, therefor it would not add any advantage to AMD that it doesn't add to Intel. For RHT to be done on the CPU, it would have to be done on a single die, not across multiple sockets.

How do you know that 4x4 will mimic server mobo design?

And 4x4 will not have RHT!

How do you know this? I'm not saying it will but speculation is on the rise. Yes, yes, rumors are meaningless, but what do we really know right now and what is speculation?

[For RHT to be done on the CPU, it would have to be done on a single die, not across multiple sockets.

Why is it mandatory to be single socket?

Because, thats what AMD has published! It is 2 AMD dual core processors. That means that there are 2 CPU sockets. If RHT is going to be implemented because 4x4 is NOT a new chip!!! Therefor we KNOW that it will not be implemented on 4x4.

If and when It is implemented, it is mandatory to be on a single socket because it is physically IMPOSSIBLE. It is either on the CPU or not.

Intel aims for 32 cores by 2010:
Chicago (IL) and Westlake Village (CA) - Five years ago, Intel envisioned processors running at 20 GHz by the end of this decade. Today we know that the future will look different. CPUs will sacrifice clock speed over core count: The "Gulftown" processor, Intel's first "many core" CPU, will run at only two thirds of the clock speed of today's fastest Xeon CPU - but achieve 15x the performance, thanks to 32 core

Workarounds wouldn't have to be all that difficult. It's not like GPU HSFs are the most elegant solution imagineable.

Where is it going to go?

So sell the DIMM with the socketed GPU or put the memory on-die.

Its going to be tough to have a 256bit bus with DIMM slots, on-die or substrate.

What if AMD has bought into Physix in a big way and are looking to have a more efficient means of CPU to GPU to PCP communication?

Its not a bottleneck on AGP so whats there to do?

If graphics memory capacity or speed is decoupled from the GPU

You can ship it out a couple of slots like a 1900XT or out the case door like the Lian Li 60plus if you want to use existing kinds of solutions. It would be possible to push it towards a blowhole. Problem is, to come to any CPU HSF kind of solution, you'd either need to target the mobo layout to a specific kind of case design or get a case maker to work with you. That's not been done before that I know of, but moving hot air around a metal box is simple tech.

So sell the DIMM with the socketed GPU or put the memory on-die.

Its going to be tough to have a 256bit bus with DIMM slots, on-die or substrate.

OK, difficult. Do you think either is possible?

What if AMD has bought into Physix in a big way and are looking to have a more efficient means of CPU to GPU to PCP communication?

Its not a bottleneck on AGP so whats there to do?

That's part of my question. If for example Physix is a focus, is a multi-socket approach part of the solution? I'm not claiming to have the answers, just wondering if we might be mising something. Sure, the talk may be baseless rumors, but what if it isn't. Just brainstorming, that's all.

If graphics memory capacity or speed is decoupled from the GPU

????[/quote]

Meaning that if you can update graphics memory independantly of GPU or vice versa, as new tech arrives, that's a potential performance advantage. Look at it another way - if one presupposes that game programmers will continue their quest for more realistic games, what GPU, memory, coprocessor, etc., changes will be needed to keep up? How close are we to AGP/PCI-e-based designs from hitting the wall? Are there multisocket approaches that will help for projected needs? For my own personal needs, current hardware and software are almost there, but that doesn't mean that the industry will stop progressing.

I like the idea to some extent. If there was a way to just swap the chip out and add more GPU ram as an upgrade.

You wouldn't have to standardize ports because you could just have one of those little cables that attach to the card and then to a faceplace with all the outputs the card supports.

Sounds good to me.
- The motherboard would be more efficient
- less non-soldered connections
- cheaper
- upgradeable ram
- easier to add bigger heatsinks

I appreciate your feedback, but still I'll just sit back and see how it unfoilds.

If and when It is implemented, it is mandatory to be on a single socket because it is physically IMPOSSIBLE. It is either on the CPU or not.

What specifically are you saying is physically impossible?
