    I was doing some reading on Wikipedia. It reports the Wii to run on a 729Mhz cpu compared to the 360 and PS3 that run on 3.2Ghz.

    Are the 360 and PS3 actually over four times more powerful than a Wii? Seriously?

    I mean, 729Mhz is slower than the original xBox...

    You're an idiot. There's a lot more to CPU power than clock speed. Learn a little more about computer architecture before you try to make these assumptions.

    Ghz and Mhz aren't the same between different cpu's unfortunately. however a 4.0ghz core2duo is twice as fast as a 2.0ghz core2duo for example.

    And yes I think the wii is most likely 4 times less powerful than the ps3. I think the ps3 even has enough power to emulate the wii if someone put the time in to code it.

    Uh, reuven, I was asking if this was true. I pointed out the power of the original xbox as a explanation as to why I'm having difficulty understanding/believing these numbers.

    I made no claims about knowing a great deal about computer architecture, that's why I specifically asked if the other systems were actually this much more powerful.

    As a side note, note not everyone can know a great deal about everything. That's a large part of why forums exist. So people of various levels of understanding can exchange and broaden the base of their knowledge.

    I mean, you more than likely know much more about a variety of subjects than I do, just as I will know a great deal about subjects you know little about.

    Now, would you care to explain if the information I found was incorrect or what aspect of the architecture of the various systems makes the information meaningless?

    Sonic, thanks for the information!

    The Wii's CPU, Broadway, is basically a faster version of the GameCube's Gekko chip, with some small additions to the core architecture. Unlike the Pentium III based Xbox 733MHz processor, Broadway at 729MHz is a PowerPC processor, and PowerPC processor's have very different architectures to the x86 based Pentium. It is very specialised and a very efficient chip. PowerPC processors, as a rule, give much better performance per MHz than Pentium chips because of how they are made, and Broadway is no exception. Even ignoring this, speed vs speed doesn't mean as much as it used to.

    Back when it did, AMD and Intel were going head to head for faster cpu speeds. The AMD Athlon first reached 1GHz, then Intel would release a version of the Pentium III that was faster still. Things changed then when the Athlon XP was released - Intel countered with the Pentium 4 and often with faster speeds, but it didn't matter. The XP was just a better chip, because of its architecture. AMD even took advantage of this with its chip-naming scheme. An AthlonXP 2000+ would run at 1.6GHz but be as fast as a 2GHz Pentium 4. Why do you think that the latest pc processors are barely scratching 3GHz? I had an XP 2000+, then moved over to a 2500+ which actually ran at 1.8GHz. When Core 2 Duo was released, the first one I bought ran at 2.13GHz, but was significantly more powerful than the XP 2500+. The cheap Pentium chip in my media pc runs at only 1.6GHz but even that is better than my old XP 2500+. The very latest Intel processors, the i7's and i5's, powerful quad-core chips, start out at around 2GHz and go up to just over 3GHz. So, you see that speed is not as important as a well-designed processor architecture.

    So, when the GameCube was released with the Gekko, a processor roughly 300MHz slower than the Xbox's chip, those who knew anything about CPU's weren't worried about the difference in speed. They knew that the Xbox chip was an x86 chip that had architecture dating way back to the early 80's for compatibility (286, 386, 486 - then the Pentium, which was unoficially the 586, and so on). They knew that PowerPC was extremely efficient, and that the Gekko would have no problems competing with the Xbox's Pentium-III based chip. So, Broadway. It is basically the Gekko, but with almost double the speed and a few changes to the core architecture to make it better suited to running the Wii and the way Nintendo - and by extension, third-parties - develop their games. You might ask, why would Nintendo stick with an older, slower chip? Well, that's all to do with Nintendo's philosophy this generation and you can read about that anywhere on the 'net (and you probably have, more than once).

    The processors in the PS3 and 360 are very fast, more modern. The 360 processor is a PowerPC chip, of a different family than the Broadway. The PS3's processor is, typical of Sony, and like the PS2, custom-made for the job. They are more powerful than the Broadway, sure. But all three have their advantages and disadvantages. So, this was somewhat long-winded, but I hope its helped you to understand a little more.

    Thank you very much, that was exactly what I was looking for. Thanks. [​IMG]
