There is overlap in every market. What about expresso machines and traditional coffee makers? Same market or different? They both do coffee, so are they the same? But I have one of both and wouldn't really want to give up either. If they were the same market, I should be forced to choose one or the other, shouldn't I? Isn't it the same with gaming? I have a computer and an Xbox. I really wouldn't want to give either up. There are always choices about where you want to spend your money. You said you play guitar. If you're looking at magazines and you see a guitar magazine you really want and a video game magazine you really want, you have to make a choice. Are they the same market because they're both magazines? If you had a choice between a case of soda and a case of beer, what would you choose? Are Pepsi and Coors really direct competitors? Just because people had to choose between spending their money on a 360 or a 7800 doesn't make them the same market.
All of those examples you gave are examples of competition within the same general markets, they're not direct competitors granted, but buying one of the two would satiate your inherent desires, whether they be for information, beverages, or video games. They cater to certain parts of their respective markets, just like PC and Consoles cater to their respective niches within the market. It doesn't mean the markets are seperate... I do understand where you are coming from, there is room for both in someones life, but understand mine, I'm saying that for those on a budget, they most definately do compete. Directly.
You can of course, break the overall Gaming market down into PC market and Console market, I'm willing to concede that, because there are those that will stick with one format regardless. But they are part of the same larger market, as you cannot deny that they compete for the same portion of a person's budget.
As for the physics chip discussion we had, may as well merge the threads to keep it easier to reply too. I really don't think that it's going to fly, whats the point of offloading physics calculations to an add-in board when your processor can handle it without a hitch. Look at how well physics works on a single core design (HL2, Doom 3 etc...)
Now imagine putting it on dual core, physics and a few other threads can run on one of the cores, leaving the other for AI and other threads. Granted, at this point, maybe a physics card COULD help.
But now go quad core, which will be here well before the end of 2007. Suddenly you have your physics on one core, and you have 3 cores left to handle everthing else. This all ran on one core, and ran well, and when quad cores fly, we're definately looking at 45nm manufacturing, which means higher clocks to boot. Suddenly the extra physics chip doesn't seem worth the extra money, because it will net next to nothing in gains.
And then Octa, which is on Intels roadmap for 2008-2009, physics on one, or two, dedicated cores, and there would still be 6 cores left to handle everything else.
And maybe I'm wrong about performance, who knows, maybe they can add refinements to a physics specific chip the way they do graphics cards, and it could out perform a single core on a processor. There is still the problem of actually getting developers to use your special physics API in their games, and making sure they spend enough time using it that they implement it properly for both those with and without the cards.
I just don't think its a viable business approach, there would need to be a healthy list of games to support it, and benchmark proven gains from doing so before enough people would purchase the product to make it profitable. In comparison, a developer could just set their physics thread to have affinity for core #2 (or #4, or #7 and #8) and be done with it. I think the simplest approach will be adopted here.
