The Pentium 4 is truly a bandwidth monster as we discovered with our initial Linpack benchmarks. While the 50% higher clock speed makes up for some of this lead, the majority of it is due to its 400MHz FSB, low latency caches, and excellent branch predictor. Too bad the real world performance of the processor, using today's applications, isn't able to take advantage of this incredible amount of bandwidth.

Again, the Pentium 4 holds an enormous bandwidth advantage over the competition. And again, it's something we don't see duplicated in the real world tests, it will be interesting to see how tomorrow's games and tomorrow's benchmarks view the Pentium 4.

The RC5 performance test is almost exclusively a measure of Integer performance. Factors such as memory bandwidth, FSB frequency or cache performance don't affect the score and as you can see, the Pentium 4 isn't doing good at all. Even with an optimized RC5 client it is doubtful that the Pentium 4 will be able to do much in purely integer tests like this one.

    First Post!!!!

    Seriously how come no one posted on these old articles? It was an interesting read on a bit of history. :)

    Maybe because there wasn't a comment section back then? /sarcasim

    10 years after first post. 15 years since article.

    Interesting piece of history. What ever happened to AMD's lead... :(.

    For 10 year in the future reader.

    I knew AMD would take the performance lead.

    this was the worst CPU by intel ever, much like Phenom launch in 2007, yet this is kind towards intel. a contrast to the phenom review. Its sad the bias.

    On the contrary I think this was most interesting ... With much higher memory bandwith, sadly clock speeds were not as impressive in early released models.

    Yeaa this history is awesome. AMD INTEL this companies needs to fight every time in the market.
    Good old intels CPUs! That is what i want.
    Check my blog: - In polish but this site is very good like this awesome post!

    hi the 50% higher clock speed very good
