Why?

[Seero]

Why does GPU be placed on mobo and must be sit on a AIB that sits on a PCIe? If they can make dual socket mobo, then why is it so difficult to make a mobo that combines the feature from AIB and a GPU socket + a CPU socket? Video cards have been using DDR5, but CPU only uses DDR3. Why?

Why can't mobo support DDR5?

Why can't CPU be made to sit on a AIB that sits on PCIe?

Why? Why? Why?

 

[Chapbass]

why not?

 

[nanaki333]

why not?

can't argue with your logic

cpu boards are available and have been for quite some time, they are just very expensive.

I've always wondered if AMD ever tried to slap a gpu chip into a dual socket motherboard though. They did open up their sockets to competitor and you can find FPGA's that fit into socket F motherboards, so why not GPU's?

It doesn't make economic sense. Onboard GPU is about reducing cost and only needs to be good enough to support the most basic 3D for 99% of buyers.

How many dual-socket motherboards are sold for desktop use? It's a tiny segment of the market, for engineering workstations that need >4 cores.

I do not like the idea as the number of I/O will have to increase and there would be like 3 DVI ports taking away space that can fit more USB ports. There are different number of DVI/HDMI/DP count configuration as well for different GPUs.

For example if the motherboard were to come standard with 3 DP in the I/O and I use a single GPU from Nvidia. The extra 2 DP will just be unnecessary added cost to my motherboard if the Nvidia GPU could not support multi monitor setup.

Changing out a GPU that is of the current design is so much easier compared to what you are suggesting. The current design is also perpendicular to the motherboard and adds more surface area for the PCB to occupy more components. If it was parallel on the motherboard as you mentioned it would be huge just to support a 4 way SLi.

The CPU has an on-die memory controller, Intel would need to redesign the CPU to make use of DDR5.

The CPU used DDR3 because it likely cannot make much use of the benefits of DDR5, yet.

You want to eliminate standards and go back to a market full of proprietary hardware solutions?

 

[Phynaz]

Cost.

 

[Lonyo]

GPUs don't use DDR5, they use GDDR5.

Also there are many reasons not to have a socketed GPU, not least of all the difficulty in making a high end GPU which would work in a motherboard socket like having a 384-bit memory bus and 12 different RAM sticks.

Can you name one that is not proprietary hardware solution please? The difference on LGA 1155 vs LGA 1156 is 1 less pin.

Proprietary isn't my problem, my problem is the degree of flexibility I can have. Look at those GPU servers where you can have arrays of video cards sitting back to back. Granded there are programming issues but we already have lots of programs that works on CPUs. We have racks and racks of servers, each have a CD-ROM and a video card.

With existing tech, it is possible to build a computer on a AIB. No CD-ROM, no video card, not even a PSU. My vision is a box with 4-8 CPU cards in it. We already have box with 4-8 video cards so what is so hard about it?

DDR3 and GDDR5 are completely different technologies; GDDR5 is not necessarily better than DDR3 if it was used for a CPU.

Hynix has DDR4 now.

As with everything: insufficient demand to justify development costs.

Bet Intel could do you a 300W CPU with 32 SB cores on a die too. But no one would buy it. So it doesn't exist.

Will you buy an AIB that allows you to recycle your older CPUs and RAMs? It may not do much but completely free your main CPU off those processes that you can't kill but are doing nothing meaningfull 99% of the time.

Because the PCB of the motherboard would be insanely complex, almost impossible to design, and very expensive. Plus the socket would put a huge limitation to the development of future GPUs, and if the customer is required to change the socket for a new GPU, now the customer is required to change the entire board.

Would you rather spend $2K or $500 to upgrade your GPU?

Don't they have the same problem with CPU?

 

[Avalon]

GDDR5 is based off DDR3, but designed for high bandwidth graphics.

Yes, and if you had to do this with a GPU onbord, it would not only be practical but a complete PITA.

Umm... PCI Express?

 

[-Slacker-]

Are we talking about gpu's designed to go into cpu-type sockets here?

 

[JSt0rm]

why must your thread title be so nondescript?

 

[Seero]

Are we talking about gpu's designed to go into cpu-type sockets here?

Yes, partially.

The other part is the other way around, having CPU card, running through PCIe.

Because I don't know how to make it more descriptive.

If I am not mistaken, PIII's used Slot 1 (SECC2), Socket 370 (FC-PGA)
and they didn't last very long. I surly don't think Intel would go the "slot" route again.

You mean a blade server?
