      Since their product is still mostly vapor (you can't buy it yet), and nVidia is currently owning them in the high end market because ATI's product is so late, one has to grasp straws in order to try look l33t in the eyes of the potential purchasers.

        A good question! This excerpt from a recent article in Extreme Tech [extremetech.com] seems relevant:
        The third future project at ATI is dramatically improved support for the GPGPU scene. These are researches, mostly academic, that are tapping into the massive parallel computing power of graphics processors for general computing tasks, like fluid dynamics calculations, protein folding, or audio and signal processing. ATI's new GPU architecture should be better at GPGPU tasks than any that has come before, as it provides more registers per pipeline than either ATI's old architecture or Nvidia's new one. This is a sore spot for GPGPU developers but not really a limitation for game makers. The improved performance of dynamic branching in the new architecture should be a huge win for GPGPU applications as well. Developers working to enable general purpose non-graphics applications on GPUs have lamented the lack of more direct access to the hardware, but ATI plans to remedy that by publishing a detailed spec and even a thin "close to the metal" abstraction layer for these coders

      The performance of GPU's seem to grow faster than those of CPU's. I remember someone had proposed to use GPU's to proces generic data. It would be 12 times faster than a CPU.

      Go here [gpgpu.org] for several examples of this -- far from simply having been proposed, it's been done a fair number of times.

      The thing to keep in mind with this is that while the GPU has a lot of bandwidth and throughput, most of that is due to a high degree of parallelism. Obviously 1 GHz hasn't been a major milestone for CPUs for quite a while, but CPUs are only recently starting to do multi-core processing, while GPUs have been doing fairly seriously parallel processing for quite a while.

      Along with that, the GPU has a major advantage for some tasks in having hardware support for some relatively complex operations that require a fair amount of programming on the CPU (e.g. multiplying, inverting, etc., small vectors, typically has a single instruction to find Euclidean distance between two 3D points, etc.)

      That means the GPU can be quite a bit faster for some things, but it's a long ways from a panacea -- you can get spectacular results applying a single mathematical transformation to a large matrix, but if you have a process that's mostly serial in nature, it'll probably be substantially slower than on the CPU.

      Along with that, development for the GPU is generally somewhat difficult compared to development on the CPU. Writing the code itself isn't too bad, as there are decent IDEs (e.g ATI's RenderMonkey) but you're working in a strange (though somewhat C-like) language. Much worse is essentially a complete lack of debugging support. Along with that, you have to take the target GPU into account in the code (to some extent). I just got a call in the middle of a meeting this morning from one of my co-workers, pointing out that some of my code works perfectly on my own machine, but not at all on any his. I haven't had a chance to figure out what's wrong yet, but I'm betting it stems from the difference in graphics controllers (my machine has an nVidia board but his has Intel "Extreme" (ly slow) graphics).

      The universe is a figment of its own imagination.

    • What exactly is "generic data"? If a GPU chip could do a CPU chips job 12 times as fast, it would be used as a CPU chip.
      GPU chips are designed to do a certain type of calculation (matrix multiplication) as quickly as possible, and, unsurprisingly, they can do it a lot faster than chips designed for a much wider array of calculations. 3D graphics is a sufficiently popular application that it has caused chips to be designed for rapid matrix multiplication, but various other applications requi

    The team, optimistic that higher speeds could ultimately be achieved with the Radeon X1800 XT, attained the record speeds using a custom-built liquid nitrogen cooling system that cooled the graphics processor to minus-80 degrees Celsius.

You could have a huge amount of room-temperature water flowing by the chip, and cool it quite effectively. However, this requires, well, a huge flow rate, which necessitates noisy pumps, etc. Besides which, you get to deal with heat flux rates, which (to a good approximation) are simply proportional to the temperature differences between the hot portions and the cold portio

      Since DirectX 8 (I think), the color values have been floating point numbers, this is to avoid loosing a lot of possible values through all blending with multi-texturing and effects (fog, lighting ect) which are of course much slower than very simple integer calculations. Even on the Athlon64's FP add and muls are 4 cycles, you'd have to make the top end A64 about 700mhz if you make them single cycle execution. (multi-cycle instructions aren't as bad a thing on the CPU as there are plenty of other things to do while you wait, not so in GPUs).

      GPUs have also tended to focus on parallel execution - at least over the last few years - increasing the number of pixels done at the same time, to compensate for not being able to hit multi-ghz speeds, so yes they have many more transistors than typical CPUs (the 7800GTX might break 300 million, well over 250 million) - and of course heat is an issue if you push the voltage and / or clock speeds to far. The last few generations of GPUs have been up around 65-80W real world draw, more than most CPUs out there. And of course GPUs have very little room for cooling in those expansion slots.
      • the color values have been floating point numbers [...] which are of course much slower than very simple integer calculations.

        You say this as if it is both true and obvious. In fact, it is false. For several years now, floating point arithmetic has been just fast (and in many cases, faster) than integer arithmetic. I have actually sped up code which was previously cleverly written to use integers, just by switching to doubles.

        What is still very slow is converting from integers to floats, and vice versa

      • The Athlon64's adds and muls are pipelined, so its still 1 per cycle. If you look at the pipeline of a GPU (dozens of stages), you'll probably find that add and mul takes even longer.

      Well, while the CPU people are finally doing dual core processors (essentially, two instruction pipelines in one die, plus cache et al), the GPU people have something like 24 pipelines in a single graphics chip. Why is it that the CPU people have such lame parallelism?

      To answer both questions. Graphics are trivial to parallelize. You know to start with that you'll be doing essentially the same code for all pixels, and each pixel is essentially independent from its neighbours. So doing one or twenty at the same time is mostly the same, and since all you need is to make sure the whole screen is rendered, each pipeline just needs to grab the next unhandled pixel. No syncronization difficulties, no nothing. Since pixel pipelines don't stop each other doing syncing, you effectively have a 24 GHz processor in this beast.
      On the other hand, you have an Athlon 64 X2 4800+ (damn, that's a needlessly big, numbery name). It has two cores, each running at 2.4 GHz (2.4 * 2 = 4.8, hence the name, I believe). However, for safe use of two processors for general computing purposes, lots of timing trouble has to be handled. Even if you do have those two processors, a lot of time has to be spent making sure they're coherent, and the effective performance is well below twice that of a single processor at twice the clock speed.

      So, if raising the speed is easier than adding another core, and gives enough performance benefits to justify it, without the added programming complexity and errors (there was at least one privilege elevation exploit in linux that involved race conditions in kernel calls, IIRC), why go multiple processor earlier than needed? Of course, for some easily parallelized problems, people have been using multiprocessing for quite a while, and actually doing two things at the same time is also a possibility, but not quite as directly useful as in the graphics card scenario.
