Media Encoding Performance

Although DivX was one of the first areas we saw performance gains with when moving to 64-bit years ago, our codec and encoding front end are both still 32-bit applications.  We've moved to DivX 6.5.1 but our test settings remain the same.  We use the codec in its unconstrained profile, using a quality present of 5 in 1-pass mode.  Enhanced multithreading is enabled and we report encoding frame rate for our 1080p source file.

DivX 6.5.1 w/ Xmpeg 5.0.3

Media encoding and 3D rendering are two obvious areas where having four cores will boost performance significantly, and thus we see the four quad-core offerings at the top of the charts once more.

Moving down the list, the 6000+ performs exactly the same as the E6400, its price competitor. After Intel's price cuts take effect, the 6000+ will have to compete with the E6600 which is about 14% faster in our DivX test. The 5600+ does quite well, falling right between the E6400 and E6300 in performance.

Windows Media Encoder is available in a 64-bit version and thus we used that here as one of our encoding tests.  Our test remains the same as we've run it in the past, only using the 64-bit version of WME instead of the 32-bit version.  Performance is reported in frames encoded per second:

Windows Media Encoder 9 64-bit  

We also looked at encode time using Windows Movie Maker, a 64-bit application that comes with Windows Vista.  We measured the time it took to encode content recorded off of Media Center into a format for posting on YouTube.  Encode time was measured in seconds:

Windows Movie Maker 64-bit  

H.264 encoded content is still not mainstream yet, but the benefits of storing your content in the new format are numerous.  We measured H.264 encode performance using Quicktime and report the results in frames encoded per second:

Quicktime 7.1 (H.264)

The Quicktime H.264 test paints a particularly good picture for AMD, with the 6000+ equalling even the Q6600.  

We conclude our look at Media Encoding performance with a simple conversion from a 304MB wav file to a 192kbps MP3 using iTunes.  The conversion rate is reported in MB/s:

    I don't think you got my point. I'm not saying AMD will go out of business, just that their path would eventually lead them to it if nothing changed. For example, let's say they didn't have a new product out in a few months. Would they continue the policy they are on? I don't know the answer to that, but I think the upcoming new core has something to do with their current policy. I guess it would have to.

    I've never thought highly of Hector Ruiz, and I think even less of him now. I liked Jerry Sanders a lot, he was charismatic and visionary, and was the only one that could stand up to Intel. Many others tried, and they failed. And it was under his leadership that AMD passed Intel with the Athlon, and much of the current situation is from technology he was responsible for. He never backed down, and made excellent strategic moves like buying NexGen when the K5 ran into snags. I never worried whether AMD would survive under him. Ruiz, I just don't like him and I don't have as much faith in him. I still don't know why they are still on the K7+ core now, it's been way too long and something better should have come out years ago. They came out with a product good enough to beat the miserable P7, but they had to know Intel would come back fighting.

    But, in the worst case, and I'm not saying this will happen, AMD will be bought by someone else rather than disappear into nothingness. IBM makes the most sense, particularly since they are out of the PC business and spend a lot on semiconductor manufacturing and developing even without AMD. In fact, I am a little surprised they aren't one company already. AMD by itself is a weakling that can only grow when their competitor missteps, and when their competitor is doing well, they lose money. And IBM/AMD combined company would give Intel fits, and be their roughly their equal.

    At any rate, the industry will never allow Intel to be alone as an x86 maker. It's too lucrative a market, and Intel has produced some of the worst processors known to mankind. Uncontested, people might actually have to use them. It won't happen. Then again, we somehow let Microsoft dominate with their lousy products. So, who knows?

    With regards to AMD knowing how to fight a price war, they have no chance in this one, outside of the Barcelona. Intel can make the chips cheaper, and they are much better processors. Plus, they still have a better reputation. Intel can take market share from AMD and make them like it right now. There just isn't anything AMD can do with their lousy K7+ and inferior manufacturing, plus high debt. And that's what's happening, Intel is winning back market share and AMD is selling their rubbish for peanuts to boot. But still, we have Hector the jackass telling all the world that AMD will not yield any market share gains, and instead will get to 30% this year. He's a buffoon, he is not in control of the situation, Intel is, and he's trying to use bravado to cover up the fact Intel will take what they want, it's just a matter of how much money they are willing to give up to do it. I really don't like this man.

    Cyrix is dead now, VIA bought them and promptly killed their line off and went with the IDT Centaur line. I actually have one of their micro-ATX motherboards and processors running at 800 MHz. It's totally quiet, and it's elegant in it's own way, but for 800 MHz it's really slow. To me, it seems like it's roughly equivalent to a 500 MHz Katmai, and I'm not exaggerating. But, it uses less than 10 watts, so I guess that's to be expected.

    This 'war' you speak of , is actually a battle, the war goes on indefinately, but yes, I got your point.

    As for who 'rules' AMD, I could care less, as long as they stay around, giving Intel a reason to make good products, and vice versa. I care more about things when AMD makes stupid judgement calls, as in switching socket types too often, and not supporting them for very long, but they are not the only ones guilty fo this, and to be honest, I am not sure if there really is much of a choice, when technology advances as fast as it is now.

    AMD would never dissapear into nothingness, and they *could* go back to making IC's only, they probably just would not make as much money doing that alone.

    Cyrix *has* been dead, for a long, long time now, at least in the desktop arena, which, in my opinion did not happen soon enough. I remember having a Cyrix P200, and playing quake2, and getting 7 FPS, popped the CPU out, droped in a P55 233MMX Intel CPU, bumped the FSP up to 75Mhz, and watched as it got over 60 FPS with the same settings . . . (I miss the good ole Super7 days, if only because the platform did not matter, you could use any CPU in it).

    Actually, VIA bought Cyrix and actually released a few products based on their architecture, and then bought the Centaur line from IDT and stopped making the Cyrix based chips.

    Cyrix chips weren't always bad, at least on paper. I always had problems with them though, but in some ways they were way ahead of AMD. AMD was just a clone maker until they couldn't do it, whereas Cyrix made their own processors without copying Intel microcode. The chips you're talking about had miserable floating point performance, but their integer performance was excellent. They used that silly PR rating stuff where they were actually clocked lower than they were rated at, because of their superior IPC. Cyrix was also unique in the x86 world for saying that the decoupled architecture of the K5 and P6 was not the way to go, because you'd have too much trouble with OOP as you got to deeper pipelines. It would be interesting to see if they'd still be running x86 code natively today, or running some inelegant decoupled architecture like Intel and AMD are. Apparently, since AMD and Intel survived, it was the way to go.

    AMD has been making x86 processors almost as long as Intel has. IBM used them extensively in their original PCs and so did Tandy. They were a licensed second source for Intel. Intel got a little greedy with the 386 and decided they didn't want AMD making them as well, although AMD eventually just reverse engineered it and did it anyway, creating a great legal battle. AMD 386s were excellent too, they ran at faster clock speeds, and used a lot less power. Unfortunately, their 486s sucked, they were unreliable. They seemed to have a lot of cache problems, and if you turned off the cache the processor ran OK, but with it, it wouldn't work. Mainly the DX2 80/40 had this, and I have no idea why.

    You complain about the Cyrix chip, but did you ever try a K5? The floating point on that processor would make a man with a hairy back cry. That's just the way it was, Intel had ferocious floating point, and everyone else had lousy floating point. It was how they were able to compete. They didn't "waste" so many transistors on something that most people never used anyway, and that helped them a lot. Even the K6 with it's low latency, but non-pipelined floating point unit was way behind the Pentium. Only the Athlon changed that.

    I don't miss Super 7 at all. You had a bunch of substandard companies backing that standard, and none of the chipsets were particularly stable. The VIA MVP3 was probably the best, the ALI was miserably bad. The MVP3 had terrible memory performance, even with motherboard cache memory. Even though it and the 440BX were both rated at 100 MHz, the memory performance on the 440BX was roughly 50% greater. The P55C didn't use Super 7 though, it used the regular Socket 7 chipsets, like the 430TX and 430HX, both of which were excellent. I still run my print server off a 430HX based Pentium 233 MMX. It does the job fine, and if I want to play any games from the mid to late 1990s, it's ideally suited for it.
