The main reason I don't buy Intel: CPUs that cost more than entire computers. $1000 for an i7-980X, versus $200 for a Phenom II X6 1090T. What do you see wrong with this picture?
Yep, that's why I said "fu Intel" like four years ago, I'm not paying for their corporate logo. Of course I was only able to do so because at that time AMD introduced their new revolutionary architecture with the memory controller mounted directly to the mother board and Hyper Transport FSB. I never looked back. Above I posted a build I'm making soon and in it is the current AMD flagship processor which only costs 229$.
Intel is way behind in the architecture race too. They came up with QPI to compete with AMD's HT but it's current maximum bandwidth is only 26.5 gigs/s and HyperTransport is capable of 51.2gigs/s utilizing bidirectional aggregation. To top it off QPI is only available with their last two chipsets, x48 and below are stuck with a max 1.6gig
Front Side Bottleneck. Intel still uses a memory bus on their motherboards too so more powerful processors and faster memory speeds mean very little when you have not one but
two bottle necks built into your motherboard.
Now Nvidia is a whole other animal and although they DO produce the overall more powerful hardware (which requires more power and runs hotter) they have been known to release defective chipsets into the market and then refuse to acknowledge their existence. After getting burned not once but twice, i said "fu too" to Nvidia and again haven't looked back.
Conclusion:The race between Nvidia and AMD(formerly ATI) is neck and neck so make your choice based on the features you want and power requirements.
AMD vs Intel is no contest. I'll take the smarter, more efficient 75% power at 50% of the price, thank you very much.
