Predpokladam,ze vetsina z vas alespon castecne ovlada anglictinu,aby si mohla prelozit tento velice zajimavy clanek o vykonnost Emotion Enginu:
What is all this talk about Gamecube and X-Box being more powerful? We have the scoop that proves othervise. Since the beginning, the world has been going ga-ga over next generation gaming and what it will mean to the industry. Will it really advance the industry as claims have stated? Will the mainstream acceptance propel the videogame world to a new dimension?Do people sometimes ask too many questions?While those are all great questions and will someday have great answers, they are very miniscule after you hear what we're about to tell you.When looking at the specs for your next generation videogame purchase what do you look for? Are you interested in the amount of VRAM? The processor's clock speed (MHz)? The spin speed of the DVD drive? Those are nice and all, but the real telltale sign of the true power of a console is the time it takes to render an image.More powerful chipsets can fully render images faster than less powerful chipsets. To explain this we have consulted a database, POVBench, of Haveland-Robinson Associates, that uses a numerical system to translate the efficiency of a given chipset when compared to other chipsets. POVBench compares the relative maths performance of various computers, processors, and compilers by timing how long it takes for POVRay to render a standard image with standard parameters. POVBench test chipsets for their performance and then rates them according to the results. The rendering time is translated into a POVmark which simply gives a numerical value for the power of the system.Think of it as a way to measure real-world processor speed and performance, while ignoring false stats like MHz. The higher the POVBench, the better.So with that in mind, let us just take a gander at some of the more pertinent chipsets in the console business and see how they stack up to one another.
First, let's examine a popular setup like a typical Athlon board. On a 850 MHz setup running Windows 98 with 256 MB of RAM, it took the Athlon 00:00:29 (29 seconds) to render an image. The POVmark was a rather unspectacular 510.34.
Now, let's take a look at one that has a little more relevance to the gaming world. The X-Box is set to debut next fall/winter and it is already being hyped as the successor to the PS2 because of its power. However, when you look at the benchmark figures for a 700 MHz Pentium III running Windows 98, which is almost identical to the X-Box specs, you'll see that they aren't so impressive.The Pentium III weighed in at 00:00:35 seconds and a POVmark of a mere 422.86. That is longer than it took the Athlon for a significantly lower POVmark. Next, we looked up a PowerPC 601, the chip that Nintendo's Gamecube is based upon, and found some very interesting results. The PowerPC was only able to amass a score of 00:00:32 for a POVmark of 462.5. One thing to take into account was the fact that it only runs at 120 MHz. However, when you look at it closer, you'll notice that there were 20 PowerPC chips running parallel on that setup. You'd think with 20 processors running simultaneously, it could do better..but that's not so.
Finally, we get to the PS2's Emotion Engine. At 300 MHz (okay, 293 MHz technically), it doesn't sound very imposing on paper when compared to the 700 MHz of the X-Box. However, with a time of 00:00:05 and a POVmark of an astonishing 2960.00, the PS2's board blew everybody out of the water.What's even more amazing is the fact that the board that was benchmarked was the beta version that has since been refined.
According to the POVBench database, the Emotion Engine is the rated as the number one single-processor board tested by POVBench. Overall, it is listed as the seventh best-performing board tested. The six in front of it are bona fide supercomputers with multiple processors. In fact, the next closest to the PS2's numbers was a listing held by a setup clocked at 00:00:06 seconds with a POVmark of 2466.67. The hardware happened to be a workstation that was running 32 Pentium IIIs at 450MHz apiece.By now, your head is probably a pile of mush held together only by your bubbling flesh and you're sitting there asking yourself, "what the heck does this all mean to me?"Simple. It means that Sony's PS2 is in the top seven among boards tested for performance. The six ahead of it were quintessential supercomputers that ran between 16 and 96 processors at once.It also means that MHz is sometimes just window dressing to entice those who are enamored with big numbers. This is proven by the instance that although the PS2 runs at 300 MHz, it outperforms the Gamecube's 400 MHz board and the X-Box's roughly 700 MHz.The overall power of the PS2 is remarkably greater than either of the other two.
The moral to this story is to be careful when comparing console specs. Just because you see bigger numbers does not always mean better performance.Of course, there are always exceptions and we're not saying that MHz do not count. What we are saying is that the true power of a console is sometimes hidden from the general public by marketing and a lot of "fuzzy math." Be careful. SonyWeb would like to thank Andy Mills of Minneapolis, MN, who was first in line for a PS2 last night at the Roseville Best Buy, for pointing us in the right direction for this story.
...Je to clane doslova prevzaty ze SONYWEBu.Predpokladam,ze se najdou chytraci,kteri budou tvrdit,ze je to nesmysl a ze kde jinde by to psali nez prave na oficial. strankach Sony.No a to je prave ono!Tento fakt o vykonnosti procesoru PS2 asi tezko budou propagovat na strankack MS nebo Nintenda,ze?
