Intel's Pros: Good performance and Bigger Cache
Intel's Cons: Price, Power Consumption, Horrible implementation of new Technologies. The price is $1000 for their 3.33 Hexa-core (six core) CPU and it is $295 for AMD's 1090T 3.2 Ghz six core which in reality actually performs at a clock speed of 3.6 ghz. you do the math. Intel is also horrible for gaming and Power users or even the mainstream user. Their motherboards specialized for their processors are $265-$700. plus there $500-$1000 proccessors if you want any good performance
AMD's Pros: Good performance, Large Cache, Price, Power Consumption, Implementation of new Technologies, AMD made 64 bit technology. All of AMD's AM2, AM2+, and AM3 processors are actually now 128 bit/64 bit/32 bit processors. They can Implement all three at the same time, but there are no 128 bit operating systems out there. There has been a leak though. The info leak says that AMD and Microsoft are teaming up to make the first 128 bit OS. Anyway back to AMD. Good for gaming. motherboards are inexpensive. They also offer, just like intel, 1-6 cores, single(1), dual(2), triple(3)(intel does not have that), quad(4), and hexa cores(6) and SOON Octo(8), Nona(9), Deca(10), undeca(11), Dodeca(12), 16, and 24 cores. AMD is alo going to come out with Fusion technology that intel cannot do with there 32 nm process. Fusion is the merginf of a very High performace Graphics processor, High performance ram, and the general processor on 1 chip while still retaining the size of the current chip today. This is expected to debut in 2011. Here is some more news Last week Nvidia’s CEO made clear what many of us had known for some time. There was a war brewing between Intel and Nvidia that Intel actually started by creating Larrabee. Many had thought the more likely war would be between AMD and Nvidia once AMD bought ATI, but that sure isn’t what we are seeing now. Apparently, AMD and Nvidia are getting along relatively well right now and both look at Intel as their major problem. In effect, Intel's Larrabee is driving Nvidia and AMD back together as partners.
AMD's cons: not as large of a cache as intel but who needs a super large cache, and AMD only support Dual channel technology for there memory and Intel has tri channel but Y pay $800 more for 1 more channel of memory which you will not even notice a difference with?
