    The future of computer input devices

    If we restrict the discussion to computers, as in working with a general computer, desktop, laptop, workstation, whatever. 1: Voice command? No, simply because menues, tool buttons, etc are so much more convenient, faster, deliberate and error free. Not only are they fast and silent methods to...

    Can single core get much faster or we hitting a dead end?

    Actually, every single angle, - in this context, and fused in that way, - of that injection, strikes me as completely wrong. But I'm tired,.. Look, Moore's law puts more transistors into your computer. How do you make best use of them? A bigger single core? Nope. That would do far less...

    Can single core get much faster or we hitting a dead end?

    Of course single threaded, single core performance can be increased. I don't think the point has been made directly here yet, at least not put directly: I think the question is how you get best value for your transistor budget. And in those terms we have come to a point where diminishing...

    What happens when we switch to light CPUs

    I think you misunderstood the estimate I was trying to make. My point was that lightspeed is too slow. The physical constrictions on a GP optical processor makes it ultimately unable to compete with transistor IC. The upscale in achievable switching speed is not able to compensate for less...

    Intel's X86 license with AMD questioned

    That is the idea. Intel have been squeezing for a good while already. You can see it in the numbers of CPUs they've sold and their low revenues which absolutely haven't matched up. Not with normal business practices either. Intel's legal position vs AMD is precarious and I think this is how...

    What happens when we switch to light CPUs

    I think light based logic will be superior/competitive in limited areas. In terms of a traditional general purpose CPU I also believe current transistor technology is already beyond what is achievable with light. Theoretically, light allows phenomenally fast logical state change. But for...

    Intel's X86 license with AMD questioned

    When it's eventually proceeded through court, contract law tends to be pretty straightforward. And as I see it, right now Intel is indeed, really, in major breech of the agreement and AMD is not. Whether AMD will, in some future, be in breach of the agreement or not is then irrelevant. I have...

    Anybody else DISAPPOINTED by i7?

    Core i7 sofar looks like an extraordinarily good processor. If you're disappointed, my take is that your perception of different performance envelopes is unrealistic. That is to say: you are comparing 'desktop' -benchmarking results for Core 2 and Core i7. I often have the impression that...

    Is there any calculation that current processors cannot calculate ?

    Accurately predicting the weather is not even theoretically possible. It would not fail due to unsufficient computing power, it fails because it's actually not possible. The reason is that arbitrarily small input conditions will eventually have very significant consequences. (Please note that...

    Why are wind turbine blades so skinny?

    QFT QFT Regarding the OP's question: It's all about aerodynamics. And nothing about torques, bearings or structures. Lowest span wise flow! Forget all that radial vs axial torque nonsense. The mission is to suck the energy out of the wind. As much as possible. For that reason you...

    Does AMD have an answer to Core i7?

    That is an incorrect analysis. You seem to be off already on the first step when you compare pricing on a server segment CPU with pricing on desktop/consumer segment CPUs. But lets leave such details and go directly to the main issues: Neither AMD's nor Intel's pricing have anything at all...

    Does AMD have an answer to Core i7?

    No. AMD's CPUs are doing very well, performance wise, right now, in every respect except for one single thing, code that is heavily utilizing SIMD backend performance. Core2 is simply wider there. But this is not a trivial thing since every benchmark this forum's population reads measures...

    New AMD chief sees clear path to recovery

    Intel has soo much to gain by killing off AMD. When they're finally so close to their elusive goal they won't let up. Nor can I see that they would be in any danger. Since AT&T, US has gone a long way towards a more Soviet style economy, with big monopolies catered for directly by the...

    Engine compression ratio - how does it affect performance and economy?

    Expansion ratio! A thermodynamic engine's fuel efficiency is dependant on its expansion ratio during the work cycle. That's why a diesel engine is more efficient. And the expansion ratio is of course directly coupled to the compression ratio. In car engines, gas and diesel, expansion ratio...

    Computing capacity. That is still the basis for 'the next leap'. You ain't seen nothing yet. Moore's law is by no means finished and processing power will make a lot of mind boggling new things possible. We're already entering that era with things like cell phones and GPS devices. You've...

    "All Chemists believe global warming is real and man-made"

    There is no scientific debate about either of these issues. Which is probably what your chemistry teacher is trying to explain. There is no "skepticism in the scientific community regarding it" as you put it. You're wrong if you think there is. Are these answers clear enough for you? There...

    Regarding building a NAS

    I don't really feel I understand your question quite. If it was true why would that be an issue for your NAS? There are a number of restrictions on memory use. These are related to many things. Hardware issues, software issues, OS issues. In context of WindowsXP and "2GB" it seems you've...

    AMD's Response to 'delays'

    cut for brevity. Intel has not always had products covering the entire market. And one of my points was that you're going to see large differences (virtually nonexistant today) and very major price markups (also pretty trivial today) as you move up the range. That is how they will make the...

    Critical update for Intel Core CPUs is out

    There is no technical info anywhere from what I've seen sofar. I assume the following: 1: There is a bug in the Core 2 processor that is more serious than these bugs normally are. 2: Intel is keeping very quiet and will not do production recall because that would not only be disaster for...

    One out of three chance: 50%?

    The OP stated that he knows that the chance of survival is 1/3. Neither did he ask for correct approaches to calculate the odds of survival. Implication being that he already knows how to do it correctly. What he did ask for was what was wrong with the reasoning that seemed to imply there is a...

    how does an SLR outperform a non-SLR

    No, a digital slr doesn't use film. It uses a ccd. It does use a mirror though. Only difference between a digital slr and a traditional slr is that the traditional slr used film behind a shutter, instead of a ccd. Not really. The issue was interchangeble lenses. The slr makes it possible to...

    how does an SLR outperform a non-SLR

    There is the issue that the ccd is then continually exposed to whatever goes through the lens. (like accidentally being pointed towards the sun). And that the ccd's vulnurability to dust will increase.

    Automobile Environmentalism: Hybrid vs. Combustion

    AMD 64 Without Windows 64 = teh useless?

    Yes, AMD64 without 64-bit OS is "useless". As others have already said, 64-bit is about memory not so much performance. You may see conflicting figures regarding max addressable RAM so I'll elaborate on Soviet's and Bobthelost's essentially correct answers. The limits doesn't really come...

    Yes , Conroe is a 64-bit processor. In one mode, legacy mode, the mode in which most x86-64 processors still run today, it's a 100% 32-bit processor. In this mode, it has no added 64-bit functionality nor is it a 32-bit processor that can run 64-bit. It's exactly the same as all previous...

    Why do spaceships have a top speed?

    Kalessian, BrownTown has the correct answers. But it might be more interesting to consider not "fuel" but split it into "reaction mass" and "energy". The only reason a space ship would have a max top speed is because it eventually runs out of reaction mass. As long as it has reaction mass...

    Can Conroe support 8Gb RAM and on what MB?

    No that's all wrong. The "address bit size" for AMD86-64 aka EM64T aka x86-64 is 64 bits in 64-bit mode. Nothing else! 64-bit code is required to generate 64-bit addresses. But people do not seem to understand how this works. You're wrong to assume that this then gives the addressable memory...

    Can Conroe support 8Gb RAM and on what MB?

    You will typically first be memory limited by the program model (2GB for each process in Windows32), then OS ability to map to RAM (4GB for standard WindowsXP, you can use more memory but it will be in swap, not on physical RAM), then Mainboard (typically 2GB-8GB). CPUs addressing limits is a...
