    If the website designer has to pay for bits each time you view their website without viewing their banner ads, are you engaged in theft?

    In order for me to view their banner ads, my browser must actively request the data for that banner in a separate transaction from the one used to get the rest of the contents of the page. I see no reason for me, as the computer's owner and operator, not to forbid the browser from doing so.

  3. Re:Clock for clock Barcelona is faster than Clover on AMD Finally Unveils Barcelona Chip · · Score: 3, Informative

    I simply want to use the chip that gives me the greatest floating point throughput I can get.

    Define throughput. At some point you need to decide if you are solving equations like LinPack or equations like spec_fp. One causes lots of cache misses and benefits from memory bandwidth, the other does not.

    Right now that chip appears to be Barcelona.

    Well that's a hypothetical statement based on perception of your needs and their marketing.

    I'm not interested with hypothetical arguments

    That explains why you're making them (???)

    I am looking forward to using Barcelona processors because they will get my mathematical computations done faster.

    Hypothetically. Are you going to hypothetically switch when Intel's Penryn with SSE4 comes out? What about Intel's Nehalem?

    By the way, check out number 2 and 3 on your top 500 supercomputer list - they're Opterons.

    And?? They were designed and built before Core 2 was released. Do you think I'm going to argue they should have used Pentium 4's? Those systems also make solid use of NUMA through a custom Cray crossbar (Seastar), and Intel doesn't have that. If they made them today I see no reason for them not to use Opterons. Do you have a computer with lots of Opterons and a Cray Seastar router on order?

    The performance of those systems is measured using LinPack. As I mentioned at the beginning, declaring a 2.0 GHz Barcelona as having faster fp throughput than 3.2 GHz Core 2 depends wholly on which types of calculations you are doing. spec_fp does calculations that are memory bound, LinPack does not (at least not as much). Barcelona's faster fp throughput is not due to markedly superior fp unit (though it may be marginally better) but its onboard memory controller. If you need that sort of thing, great, go with barcelona. If you need raw speed on smaller units (under a couple of megabytes) chances are good that the higher clocked Core 2 with huge cache will win.

  4. Re:Clock for clock Barcelona is faster than Clover on AMD Finally Unveils Barcelona Chip · · Score: 2, Informative

    When only measuring single core performance, clock for clock, Barcelona is on par with Cloverton.

    Unfortunately processors are not generally sold "clock for clock." If you're on par clock for clock, but the other guy is clocked more than 50% faster than you... that could be trouble.

    What good is an Intel chip that has fast floating point but the bus cannot feed it data fast enough?

    Plenty good if the data can fit in cache, in which case the unit can be fed fast enough. For instance, say you're running LinPack. But then, who uses LinPack as a benchmark?

    specfp rate was running faster on pre-barcelona dual core Opterons than on Intel's dual core Woodcrest. The reason is no big secret: specfp is memory bandwidth limited and specfp_rate is specfp's running in parallel. Here is a good anandtech article on the subject.

    We already know that AMD has superior memory performance. If you are doing bandwidth-limited floating point, Barcelona is the clear winner.

    If you're making a general statement about floating point performance, you're wrong.

    Is that a *really* good metric for a language? O'reilly is pretty good as companies go, but they are still after the bottom line. And the bottom line is: bigger "quick references" will sell better and for more money.

    And then why does it take a zillion pages in the quickref to explain it when it has less fearutes than stock perl.

    See, just like I told you.

    Once you learn perl you don't need a big set of reference books to explain every obscure library.

    Is there a language that, once learned, you need a big set of reference books? I use both Perl and Python (and 4 or 5 others). I have no books on Python. I have the camel book for Perl. I still find Java's javadoc to be the best language reference around. I no longer program in Java so that's just an interesting side note at this point.

    How did this get modded informative?

    Intel's Core Microarchitecture is not currently available in a quad-CPU platform.

    Incorrect. Intel's "Core Microarchitecture" is marketed under the name "Core 2." The "Core 2 Quad" processors use the Core Microarchitecture. See Intel's product brief on the subject.

    It is understandable the multithreaded performance would be poor, then.

    The single threaded performance of quad core is similar to the single threaded performance of dual core, clock for clock. This should have tipped you off to the fact that quad core is using the new microarchitecture.

    The current quad-cpu architecture is based on Tulsa, which a 65nm shrink of Paxville, which is essentially a Pentium 4 Smithfield, or two Prescotts shoved onto one ship.

    If they performed slow re-entry (ex: SpaceShip One), then one of their two failures would not have occurred as the heat would not have built up.

    SpaceShip One is sub-orbital with a maximum speed of about Mach 3. I don't understand how you can compare the two. A "slow" re-entry would require a whole lot of fuel to slow the vehicle down from orbital velocity to a safe entry velocity. Fuel you would have to launch with. You'd have to burn the fuel relatively quickly to ensure you don't enter a highly eccentric orbit that intersects with the atmosphere before you've finished your maneuver. If anything goes wrong here, you're toast. You'll burn up in the atmosphere.

    Oh brother. So when the GOP has a majority, the Democrats cry that they don't have any power to stop anything.

    I think you need to take civics again. The Democratic majority in congress is very slight. They cannot override a presidential veto. It would take a bunch of Republicans to side with the Democrats to do that, and that simply isn't going to happen for a variety of reasons. In short, the Democrats are unable to pass new laws that Bush disagrees with. They can allow existing laws with sunset provisions to lapse, but they can't erect new laws. Bush worked very hard to consolidate and solidify power in the executive branch. It takes new legislation to undo that, and the president has to sign off on that new legislation.

    A great example of this is Bush abusing his lame duck position to finance the surge in Iraq. Bush doesn't have to impress anybody, he isn't running again. The democrats had two choices: finance the war without a withdrawal timeline and get a black eye for not delivering on their election promises, or don't finance the surge and get a REALLY BIG BLACK EYE from public sympathy for millions Katrina victims and minimum wage workers. What the hell were they supposed to do??

    Despite the fact that there was a clear national mandate from the people for a speedy resolution to the situation in Iraq, Bush could comfortably ignore it.

    People have now seen Democrats "in action", the Congress has a lower approval rating even than Bush, and that is not unimportant going into a presidential election year.

    Newegg has the E4500 for $146. That comes with 2MB of shared L2 cache, which is twice the combined cache of the Brisbane. In a single-threaded game this means that most of the L2 is going to be used by one processor for the game giving the CPU access to almost 4x as much. Is the shared cache a problem?

    That has a bottlenecked 800Mhz FSB, not a fancy 2.0Ghz hypertransport bus like the X2.

    Let me start by saying that a dedicated cpu memory controller plus high-speed chip-to-chip interconnect is the way to go. Having said that, this comparison always annoys the hell out of me for a couple reasons:

    1) FSB is wider than hypertransport.

    It's an alleged evil. Since the only major Intel-only brand in the US was Dell, I don't find it a particularly compelling case of evil. In fact it is a pretty short walk from saying Intel was manipulating Dell to saying Dell was manipulating Intel (hey Intel, I hear AMD has some pretty nice procs, sure is hard to turn those down, unless maybe we got a big discount on our next batch of cpus).

    Intel doesn't have to buy AMD's IP. If AMD goes belly up, then Intel will have an unchallenged monopoly, and no one has suggested trying to compete with them.

    AMD and Intel are fighting it out right now. The margins for each company are so low and the cost of entry so high that nobody else WANTS to jump into that alley fight. If AMD goes belly up, the cost of entry (buying AMD IP) gets a whole lot cheaper. If Intel jumps its gross margins, the potential returns of entering the market get a whole lot larger. "Unchallenged Monopoly" is just sabre rattling. It isn't going to happen.

    Barcelona is late, and Intel does have a better manufacturing process. No one is contesting either of these points, but cheap AMD processors are reaching the 3 GHz barrier, so only trolls insist that AMD will never hit that mark.

    Of course that is a strawman, as I never said nor implied AMD will never hit that mark. It's fairly certain in the market that AMD is having yield problems due to leakage on their 65nm parts. They are delayed while they get that under control. It also explains why initial Barcelona ships will be binned at 2GHz and only to key customers. AMD will have at most 8 weeks to get Barcelona penetration going before Intel starts shipping its 3.2GHz 45nm "Penryn."
