Intel Core 2 Extreme QX6800: The Fastest Desktop CPU, now with more cores

Final Words
The performance crown continues to undeniably belong to Intel, the QX6800 simply gives you the option of having four cores at the performance leading clock speed. The price is obviously quite steep, and those who are not opposed to overclocking would be better off buying a Q6600 and simply overclocking it to QX6800 speeds. It would make even more sense to wait until the end of April and buy a Q6600 for $530 and then overclock it, if you truly want four cores at close to 3.0GHz. Other than the price however, there's nothing wrong with the QX6800 - it's got four cores that we all know and love, and it's fast.
Penryn is several months away, so waiting to build isn't really an option if you need a computer now. If you already have a Core 2 system, please do resist the urge to upgrade until Penryn and Barcelona come out as you'll have better performing choices and/or cheaper alternatives.
Pricing is a major focus of the desktop CPU industry these days, and believe it or not, CPU prices will get even more competitive by the end of the year. Thanks to AMD's recent price cuts the Athlon 64 X2 line is finally competitive, across the board, with Intel's offerings. The Athlon 64 X2 6000+ is a realistic alternative to the E6600/E6400, the 5600+ competes well with the E6400/E6300 and the 5000+ can hold its own against the E6300/E4300. At these prices, you really can't go wrong with either AMD or Intel. If you want the absolutely highest performance, Intel is still your only option, but at the sub-$300 mark both companies are quite competitive.
For the consumers, things couldn't be better - you actually have even more choice today than when Intel's Core 2 processors first arrived. Back then, none of the AMD processors made any sense to purchase, but today you can't go wrong with either. From a market standpoint however, things aren't looking so good for AMD. In less than a year, Intel managed to relegate the strong, competitive AMD back to the company it used to be: simply offering good value. Hopefully, for AMD's sake, Barcelona can restore some of the performance leadership again - otherwise these next two years are going to be rough with back-to-back launches of Penryn and Nehalem.

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.
