nvidia quadro fx 5800 claims the most powerful graphics card ever

amazingly it can only process 4 gigs of video memory. But is it used for more then just gaming? Absolutely. I actually didn't know high quality graphic card processors were used for anything more then like gaming or maybe computer animation for other things, movies, etc. etc. But they are.
Now is this graphics card anywhere close to the The Blue Gene/P supercomputer at Argonne National Lab with 2500,000 processors? Hell no. But who is to argue with nvidia, they create the worlds leading gpu's, hell I even think they created the gpu for the xbox 360 or the ps3, I'm pretty sure one of them has a gpu created by nvidia.
What puzzles me is, why is it they can fit 250,000 cores into a set of boards in major server machines synchronized together in a huge lab, but can only process 4 gigs of graphics memory at one time? There must be a good reason, because nintendo was around for like longer then a decade before the ps1 came out. and I believe the ps1 had like a 1ghz processor, 130 gb of ram, and the gpu was equivalent to like the processing capabilities of dx2 or something like that 
I don't know, just saying it's interesting. But it's also cool that a gpu can do so much more then play video games, because with computers, of all the kernel processing, of all the features, nothing to me is more fascinating then how the gpu and cpu work together to process just a few kilobytes of data per mili second. I will say gpu processing isn't just about speed, but design technology, polygons per second etc. I think the current xbox 360 gpu can process 500,000,000 polygons per second if I'm correct. a major leap from doom which processed what, 250,000 polygons per second I believe? It's amazing how 3d technology always involves such exponential numbers

suess! I didn't mean to turn this into a questionnaire but it seems you interpreted it that way. I suppose non uniform memory access, cluster computing, and symmetric multiprocessing will explain why a gpu can only process 4 gigs of memory per load while you can hook up one hundred thousand cpu's in theory and in practice and 24 hard drive raid configuration in theory and in practice as well? all this allowing you to run major amounts of memory through a computing system at one time while graphics can now run a measly 4 gigs? which is epic compared to the previous record of like 256 mb 9 or 10 years ago?? well.... give me a second. I wanted this to be a nice conversation but I guess it can be a google fest. don't know why I bothered trying to make it a discussion then, but w/e

Yes, it will. The short answer is 32-bit address space, but the short answer doesn't make much sense without understanding the underlying technologies listed.

wiki:
Non-Uniform Memory Access (NUMA) is a computer memory design used in multiprocessors, where the memory access time depends on the memory location relative to a processor. Under NUMA, a processor can access its own local memory faster than non-local memory, that is, memory local to another processor or memory shared between processors.
NUMA architectures logically follow in scaling from symmetric multiprocessing (SMP) architectures. Their commercial development came in work by Burroughs (later Unisys), Convex Computer (later Hewlett-Packard), Silicon Graphics, Sequent Computer Systems, Data General and Digital during the 1990s. Techniques developed by these companies later featured in a variety of Unix-like operating systems, and somewhat in Windows NT.
A computer cluster is a group of linked computers, working together closely thus in many respects forming a single computer. The components of a cluster are commonly, but not always, connected to each other through fast local area networks. Clusters are usually deployed to improve performance and availability over that of a single computer, while typically being much more cost-effective than single computers of comparable speed or availability.[1]
In computing, symmetric multiprocessing (SMP) involves a multiprocessor computer hardware architecture where two or more identical processors are connected to a single shared main memory and are controlled by a single OS instance. Most common multiprocessor systems today use an SMP architecture. In the case of multi-core processors, the SMP architecture applies to the cores, treating them as separate processors. Processors may be interconnected using buses, crossbar switches or on-chip mesh networks. The bottleneck in the scalability of SMP using buses or crossbar switches is the bandwidth and power consumption of the interconnect among the various processors, the memory, and the disk arrays. Mesh architectures avoid these bottlenecks, and provide nearly linear scalability to much higher processor counts at the sacrifice of programmability:
Serious programming challenges remain with this kind of architecture because it requires two distinct modes of programming, one for the CPUs themselves and one for the interconnect between the CPUs. A single programming language would have to be able to not only partition the workload, but also comprehend the memory locality, which is severe in a mesh-based architecture.[1]
A computer system that uses symmetric multiprocessing is called a symmetric multiprocessor or symmetric multiprocessor system (SMP system).[2][3] SMP systems allow any processor to work on any task no matter where the data for that task are located in memory, provided that each task in the system is not in execution on two or more processors at the same time; with proper operating system support, SMP systems can easily move tasks between processors to balance the workload efficiently.
didn't really explain my question about why gpu usage is so heavy on the system, but whatever. I guess the main point of this thread goes unnoticed so that google reigns again

Yes, it will. The short answer is 32-bit address space, but the short answer doesn't make much sense without understanding the underlying technologies listed.
still doesn't explain it, they now have 64 bit address space. but video processing didn't stop there, they have 4 gig address space now. it can process 230k bps so I assume 4 gigs is maximum cache. but where have we exceeded 64 bit bus speed for address space? even in a cluster environment, how can one core exceed 64 bit data bus architecture?
where is all this being cached too? higher ram has been around. 64 bit bus has been around. it seems just the maximum gpu storage has increased. I believe 64 bit processors weren't around until 1995 am I right? I'm guessing you can't cluster together video cards in separate boards any more then you can cluster together ram in separate boards? but you can put 24 gigs of ram now on one board. how does the address space change the way this technology is developed? is the processing being multiplied more efficiently in other ways?

The ps1 had 130gb of ram? I'm really lost by this whole post, you tripping dude?

whoa mb, 130mb. was it 130? I'm not even sure if it was that high. mb, not gb. nothing has 50 gb of ram. I don't know maybe a super computer. I wouldn't know. I probably was tripping, this IS the shroomery

Playstation has 2mb of ram. Not much, but it's data transfer rate of 132mb/s was pretty damn fast at the time, so it could shift a lot of data despite so little ram. Computers at the time had anywhere from 8-64MB of ram.
Xbox 360's GPU is made by what was then ATI, but now AMD.
Dude, it's not hard to check your facts. You gots t'internet, it don't cost nothing to look at wiki.

well, anyway, yeah I was throwing out a general guess. but yes I was trying to stress the idea of major differences. MAJOR difference though huh?
180,000 polygons per second versus 500,000,000 polygons per second. pretty HUGE difference I'd say. xbox 360 has EXTREMELY good processing as well, at only 512 mb of ram, I'd say it runs pretty fast all the data it processes:
