    Not that I want to help the troll to whom you respond, but the Hammer was initially projected for a 2001 release. Barton was initially slated for something like early to mid 2002. Of course they're late. But they're not so bad as the aforementioned troll mentioned. Their processors are far more competitive than, for example, when they had the K6 family. It is simply that it's been over a year since AMD's processors were definitively faster on the highest level for Microsoft Windows (they still have an advantage, iirc, in prominent Linux benchmarks). And AMD is only seen by the general geek public as "equal" to Intel if their processors are simultaneously unarguably faster and cheaper. Right now, they're merely almost as fast and generally cheaper, so people get confused as to whether or not the company still exists. ;)

    But I digress. The AMD processors in question, just like most AMD, Intel, Motorola, Sun, IBM and HP processors, are much delayed.

    > But the geeks there said this is normal behavior.

    Of course it's normal behavior. Windows is (well, basically) counting the number of threads that the system can simultaneously execute (that's probably not entirely an accurate depiction), not the number of physical processors. But this does not mean that you're getting the performance of four processors. You still only have the execution resources of two processors at your system's disposal. The best that simultaneous multithreading can do is make more efficient use of the existing execution units. This can result in very nice performance boosts, no performance boosts at all, and (in some rarer circumstances) performance penalties. But it is in no way anything near like having that actual number of processors.

    Probably, a good rule of thumb would be "if it already stresses the execution units, then you won't see a boost, but if the code causes frequent thread stalls, then you'll probably see a nice jump".

    *EDIT* Crap, I didn't notice that you said top. Made the assumption about Windows. Sorry about that. My post more or less stands as the same, though. :)

    You have a point, but he does, as well. SMT ("hyper-threading") should work automatically for multiprocessor systems. So if you have a dual processor, SMT-capable board in a system that's unaware of the SMT functionality, you should still get a boost from SMT. Unless Hyper-Threading is a really, really bizarre implementation of SMT. Reviewers should really compare against an SMP system that is incapable of doing SMT, because it'll do it automatically (or it should), even if you don't tell it to. Alternatively, you could approximate the same results by forcing the system to only use a number of threads equivalent to the number of processors. Not all programs can do this, though (compiling is the only thing that immediately comes to mind).

    Granted, I've been out of the loop a bit, so I might be making some really off the wall (and inaccurate) assumptions about Intel's SMT implementation.

I would *love* to make two thousand dollars each month after taxes. As it is, this year I made less than $1500 a month *before* taxes, though I *might* make $2000 per month *before* taxes next year. What's that? $1500/mo after taxes? Combine that with $2500 in unexpected car repair payments, more than another thousand in car insurance, $2600 in rent for the year, tons of gas money for my 45-minute-a-day commute, then add food (and I'm on a [successful!] diet, so I'm actually spending a lot less than I otherwise would) and assorted other requirements that don't come to mind at the moment, and the end result is that I have barely enough cash to go to the movies with my friends every week. Geez, is it any wonder why people steal mp3s (I don't, but...) and other luxuries instead of footing the expensive bills for them?

    Incidentally, are you sure you're making below minimum wage? I think that's $5.15 in the US still. I may be incorrect, but if that's the case, you'd have to work four hundred hours to make two thousand dollars before taxes, and probably more like 550 hours a month to make that after taxes. That's 25 hours a day if you don't count weekends. Colour me skeptical.

Because some of the parts may not reach all the servers, a bunch of parity files (.PAR) are also put onto usenet for each of these RAR sets. If you're missing some RAR parts, you use the parity files to rebuild those missing fragments. But this is an intensely computational process, and it could take a *looooong* time before you're all rebuilt.
