Intel's 2.4GHz Pentium 4 Unleashed

EconolineCrush writes: "Intel has released a 2.4GHz version of its Pentium 4 processor, and The Tech Report does an excellent job comparing its performance with previous Pentium 4 processors, and the latest in AMD's Athlon XP stable. There's more to this story than just another notch on the MHz pole, as the review showcases some new benchmarks in an already diverse set of tests, and shows the new P4 leveraging an impressive performance from RDRAM-based platform. Incidentally, the slack demand for RDRAM has it almost as cheap as DDR SDRAM."

Of course a little bit always gets out but at those frequencies lead inductance is going to kill much of it anyway.

      It's been shown before that electromagnetic interference from processors can show up in a radio if you listen on the same frequency of the processor.


      That is very true. Several years ago, I was working on an antenna design project at a university. We had a spectrum analyzer and a small antenna test rig. Even if I connected a low gain antenna to the unit, I could see spikes at all of the "computer" frequencies...20, 25, 33, 50, 60, 66, 75, 90, 100, 133 MHz. Those were the heady days of the fast 486 and the first- and second-generation Pentium I.

      Just to check that it was coming from the neighboring engineering building, I put a directional antenna and could "detect" which computers were in which floors. The undergrad lab had all of the crap 33 MHz boxes. The grad lab on a different floor had the 100s and 133s.

      The question is bandwidth - how much bandwidth of electronic interference does the chip radiate? Probably not a lot.

      Read up on the effects of narrow band transmitters on spread spectrum recievers and visa versa. Typically the frequency hopping mechanism can avoid interference with narrow band trasmitters and narrow band transmitters typically recieve low background noise when adjecent to spread spectrum transcievers. In summary the two devices can co-exist on the same frequencies and pretty much not interfere with the two.

    Why are we comparing a ~$600 chip (P4) to a ~$250 chip (Athlon)? Sure, it's fun for a little ego brawl to see who has the fastest chip on the block, but this has little practical information for the consumer. All this says for Intel is "Hey look, I can build a slightly faster chip for SSE2 optimized apps for 250% more!". I'm not impressed. It's not only the MHZ that don't matter, the AMD "model numbers" should be irrelevant too. What really matters is price/performance. I'd rather see a ~$250 Athlon benchmarked against a ~$250 P4. Then simply mention that if you want P4's fastest offering, you can plunge $600 for it.

    Not necessarily. The V6 GTI I bought for the wife creates more horsepower than the majority of US made SUVs which are typically based on engines that were originally designed in the 60s. Equally the V8 in my XK8 will easily outperform the V12 engine Jaguar used to use [and still do 20 Mpg arround town rather than 10]

    What really matters though is the chasis the engine goes in. For example the GTI will nail any SUV in the street, even if you dropped the Jaguar engine into it. Heck you could drop the engine out of a Ferrari F40 into a Ford Exploder and the Jag would beat it round any track. To go fast arround a circuit you brakes matter as much as your engine.

    Its pretty much the same when you get to MHz. A 2.4MHz processor will probably go faster than a 2.0MHz processor all things being equal. However how much faster is pretty variable and all things are usually far from equal.

    Unless you have the motherboard and O/S design that will support the beast you will probably notice about as much improvement from a 2.4MHz processor as painting a go faster stripe on the box.

    Unfortunately most of the O/S in common use tend to spend a lot of time in unnecessary wait states. They ask a piece of hardware to do something, guess how long it will take and poll for the result. This isn't the way it should be but it only takes one baddly written driver to stonk the whole machine.

They will likely facilitate the radiation of some of the ~75 watts dissipated inside the chip package. Simple physics: energy goes from source to sink -- there is less similar radiation outside the package, thus there will be leakage. Fact of life. Need to reduce / prevent interference? That's what the grounded metal case is for.

    Second, at 2.4 GHz a signal doesn't follow a wire (or a circuit board trace) like it does at 60 Hz. At 2.4 GHz a wire is more of a 'suggestion' than a 'command'.

This is where I expect problems and performance degradation to have their roots.

    Perhaps you remember a few years ago when it was trendy to install shielding around your audio card for a greater Signal/Noise Ratio? I saw people use copper flashing (the stuff you use to keep your roof from leaking) to construct a box, doing a very nice soldering job, use stand-offs for installation... all to remove a little static. The whole trick was to construct a Faraday cage that would allow the ISA connector (remember those?) as little clearance as possible, without actually shorting it.
