If there was a competitor for the 6 core Intel the price would drop. Its not rocket science, it happens each day, and Intel is no magical exception - far from. The x86 cpu is needed all over the b2b market, and there is no alternative within realistic reach because of the enormous TCO involved on the customer side. Period. Get it?
You are stating the obvious, that a more competitive market would make Intel accept lower ROI/ROE, but that competition isn't AMD. AMD is small enough and too behind the technology curve for that.
All the celeron, pentium stuff is because of AMD, without AMD there would not have been such thing.
Oh, really? So Intel designed specific Pentium and Celeron SKU? Just because of AMD?
Celeron and Pentium are die-savaged i3, they are not a specific SKU. You are assuming that Intel would throw troves of failed i3 in the toiled and go for another run on its fabs instead of selling those failed SKUs for a few bucks, just because of AMD. Given Intel necessity for high volumes, I don't see this as a viable theory.
And now, if it wasnt for A15 and bobcat on 28nm we wouldnt see Atom on new process nodes in the agressive moves Intel does now. Its a direct consequence of competetion.
Silvermont because of AMD? wow, thanks. And here I thought that Intel was pushing so hard on Atom for it to have an edge over ARM on tablets.
If there was competition on the top we would easily see 8 cores , there is plenty room.
You forgot Westmere-EX, a 10-core CPU.
But I you are wrong here. SNB-EP die size isn't really small by any standards (sure, smaller than AMD big chip, but that's not anything to talk about), and TDP have to be in check. A SNB-EP MCM would have twice the cores but would probably operate at very low frequencies, something that would impair single thread performance.
Single thread performance is very, very important. You can't paralellize everything and once you reach this limit, the speed of your program will be dictated by the sequential part of the code, where IPC is the only measure that matters.
This "Moar Cores!!!" cry is nothing more than AMD marketing at work. Is it always the answer? I think it is not:

Worse yet, any potential customer thinking of buying on price will be scared away by one other little problem, power use. The Xeon is a 135W part, the Opteron is 115W, so AMD is better right? Differences in how TDP is calculated between two companies aside,
to do the same about of work, AMD needs two 115W CPUs for every Intel 135W CPU, not to mention the overhead of servers, switches, storage, and everything else. Power costs are a significant portion of TCO, and AMD is almost twice the power use of Intel.
Moar cores!!! does not always mean moar Performance, but always means Moar Complexity and Moar Heat.
I do think that it's not entirely lack of competition that prevent better Intel server chips, but stricter validation requirements for the mission critical servers they are trying to dominate and design trade offs such as power consumption and die size area. It is a more balance approach than being Gung-Ho on core count.
And yes i agree its not AMD that is the main competitor for Intel any more, its TSMC and Samsung, but even the slight competition they give from bobcats to the apus, still have a significant impact on the market. Even a small player with low volume can force prices down.
If it is a small player with low volumes they can't force prices down, as it will either lift its price or will run out of units well before having any meaningful impact on prices. That's not really AMD case here.
You seem to think that the low prices are because of AMD presence in the market. It isn't. AMD is losing money right now, which means that if they could sell their chips for more they would. Low prices comes from Intel relentless drive to maximize their own profits with enough cash flows to stay ahead of the rest of the industry. What sometimes happen is that AMD carves a niche and Intel responds in the next generation or two wiping it out of the market. It's been a while since AMD came with a truly innovative or disruptive product.
So in a sense we are all better with AMD around, but not much better. If the company go under there won't be price hikes or total lack of innovation. It's not 2003, Intel can supply the entire x86 market if needed and has ARM to worry about in the future, and Intel has to push itself hard enough to keep the interest on new hardware.
