Haswell isn't going to be the downfall if intel, but think of this. Next-gen, intel continues with the "good enough" idea. Then, AMD releases a mildly surprising CPU. Intel keep their pricing, AMD keeps theirs. Now, the generation after that, AMD gets a little bit better, and intel keeps the "good enough" theory. I'm not saying intel will become AMD, nor the other way around, but it might get a bit more competitive and that'll make us happy.
I don't see it happening. Even if AMD released a chip 50% faster than intel right now, it wouldn't change anything for 99% of the consumer users of PCs. They don't have applications that can use the speed. How much faster will my web page load with it?
You're thinking from an enthusiast standpoint, from a general user standpoint who just does wordprocessing, webbrowsing, listens to music/youtube, you can still use core2duo and do all of those things easily. I STILL do. My Haswell machine is strictly for gaming and storing media. If I want to browse the internet, I have my laptop and I don't need a new one because this one is still able to do everything I need.
If AMD focuses on performance, they will fall FURTHER behind intel.
Desktop PC sales are declining like mad. You want AMD to focus on a declining market?
Tablets, Laptops, Mini PCs, Phones are where sales are being made. Not performance parts.
AMD needs to focus on getting their power consumption down so that they can be viable in those markets. They are doing this already. When the power consumption is low, combined with AMD's low costs, and good enough performance, they'll do much better and be viable alternatives for OEMs, maybe even preferred, to put into the markets that are growing.
Stating that AMD should be worried about outperforming intel in performance is just shortsighted, even backwards thinking. This all mattered 8 years ago. The second Core2Duo released, we stopped seeing much of the benefits of high performance CPUs in anything other than gaming, servers, etc.
Word Processing, Web Browsing, etc general computing, won't see a boost because you release a much faster CPU. Neither AMD nor intel care about a dying market, so I don't see why you think any of what you said would happen.
I won't be buying one. I am currently running an e6400 and playing games at 1920x1200. Bought an SSD a year ago so games would load faster and have been fine up until some of this year's games (Neverwinter MMO is an example).
Based on the reviews I've seen unless you really need the newer tech I'm shooting for a 2500k. Seems to be the cheapest option for me to run games well. I thought about just getting a q6600 since I would only need the CPU but I don't think that is going to be enough.
Point proven just look at the amount of people on sandybridge or before. A much lower percentage of software stresses the CPU, so much less emphasis on CPU speed and more on efficiency.
