Intel’s core i7 990x is wold’s fastest commercial home pc 6 core cpu (WICKED FAST).
They are one step head from AMD like in the case hyper-threading and turbo boost
Most of intense RPG and hardcore games are developed on Intel’s platform.
They also support virtuallization and their new core CPU family also supports in_built graphics for more flexibility.
But diamonds are cheap their 990x is five times costier AMD’s fastest Phenom II X6 1075t @ 3.00Ghz and that’s a bummer.But their mid range is awesome i.e. Core i5 and Core i3 with built in visuals,hyper threading and turbo boost.
NOTE:Core i3 does not turbo boost and many versions of core i5 does not have built in visuals and hyper threading but ther support turbo boost.
And with sandy bridge will bring dual core and quad core on a smaller die, for better performance, less power consumption and better visuals. Eg- Intel cpre i7 2600k
Pros: Best in everything!!!!!!!!!!!
Cons: EXPENSIVE :-X
They were firsrt to bring Hexa-core computing on a single die, which is awesome, their power consumption is also bit low than intel most processors.
Phenom II X6 1075T is their fastest and best processor having six core @ 3.00Ghz (WICKED FAST)
^^^^ THIS PROCESSOR COSTS FIVE TIMES LESS THAN 990x :o.
Pros:Cheap, good performance.
Cons:Runs hot,no virtualization,not that supportive
So there is no clear winner. Go for intel if you a want a mind blowing computer without worries about money, go amd for good if performance at good price.
