NEW Standard for PCI-E

post #1 of 22
Thread Starter 
It looks like there is some truth in the speculations about the power consumtion of the next VGA. http://www.pcisig.com/specifications...eview_zone#gce

PCI-SIG
PCI Express 225W/300W Graphics Card Electromechanical Specification Revision 0.3 Draft (1.10MB PDF): This specification is a PCI Express 225W/300W Card Electromechanical document that addresses graphics power and thermals greater than those supported by PCI Express CEM 1.1 and PCI Express 150W 1.0. Its purpose is to provide additional capabilities for PCI Express graphics within the existing framework of an evolutionary strategy that is based on existing motherboard form factors. This specification is primarily designed to deliver additional electrical power to a PCI Express graphics add-in card and provide increased card volume for the management of thermals.
Other stuff from Intel Developer Forum.


Quote:
- 1.0 Spec release targeted for early 2007
– Support optional 225 W and 300 W graphics requirements for add-in cards and systems
– Standardize new power delivery connector and new power sequencing scheme
– Define interoperability between 225W/300W graphics components [225W and 300W cards have new interface boundary conditions that may require improvement to existing chassis form factor and power delivery systems.
– PCI PCI-SIG investigating ATX form factor
– No intention to preclude BTX form factor

Like ive said before GPU manufacturers need to get with the program. Even new chip from intel and AMD has been getting more powerful while consuming less power. I think they need to take soem notes. Intel went from 90nm to 65nm and the power decreased and the perfromance went up. AMD went from 130nm to 90nm the power decreased and the perfromance went up. ATI went to 90nm and the perfromance went up alng with the power requierment, same from nvidia. What are they doing wrong that everytime they decrease the die size the wattage goes up?

SERIOUSLY! The worlds freakin dying because of energy consumption! NVIDIA and ATI are like big oil companies!!

ATI + Nvidia mean more power usage, higher electricity bills, LOUDER COOLERS, all other components hotter = less overclocking

That's what you get for drinkin too much.....

Anyway, this means that the next generation of cards will use so much power that you will have to buy:

1) New PSU
2) New GPU
3) New MoBo because they will have different sockets

Also, they will run hotter and less effeciently.

That's what it means. PCI-E is already a dying technology apparently

There's just no incentive for Nvidia and ATI to make more efficient graphics cards. Intel and AMD did only because they were fighting to make the most efficient processors for server use. Buyers of high energy consuming GPUs don't usually pay attention to the heat or energy costs, so Nvidia and ATI completely neglect them. Let's all teach them a lesson by not buying their next super powerful GPU

It means that the cards will need much more power, which should lead to more heat, and a bigger cooler.

So you will proboly need a new power supply and if they run to hot you will get worse overclocks on them.

Essentially this means that a new breed of motherboards may come out with different specs for powering the grpahics devices, and maybe a new connector as well.


As for making chips smaller, cooler, and faster. its not like there is a magic switch that just lets them go to a smaller process. its millions, if not billions of dollars, to switch fabrication processes and while ATI and NVidia are market leaders for sure, they likely dont have the capital that CPU manufacturers do to upgrade as soon as the technology is ready.

Intel has billions to pour into new processes, and it jumped on the 65nm bandwagon as soon as it was feasable. AMD, who also has oodles of money, has been trying to break into it as well (with limited success, as reports indicate).

ATI and Nvidia make markably different processors from Intel and AMD, and its just not as simple as sending it to a new facility. ATI has said that they are going to 80nm process asap and I am sure that Nvidia is planning on it to. This means the same speed for a lot less power, and also better yields per wafer (meaning lower prices). However, when processing power seems to double every time a new card comes out, its no wonder that going from 130-120nm to 90nm didnt REALLY drop temperatures and power consumption. They have been having exponential growth, practically. This is NOT something that CPU manufacturers can claim (aside from Intel and their core release, which was essentially an upgrade 5 years coming).

Yikes.

The GPU market is pretty much trying to approach new core design by combining the CPU market's old and new approaches - and it isn't really working. The CPU market has recently switched from MHz pumping to smaller processes and more effecient designs. The GPU market seems to be pushing smaller processes combined with a whole lot of MHz pumping -making very hot, ineffiecient, yet smaller processes. Once the GPU market exhausts the power of air cooling, like the CPU market was starting to do before the power craze, we will probably see them switch to the conroe approach.
