er ok first why is anyone commenting on a pentium d processor, its by nature slower then a C2D because its intels older technology called "netburst" its a power hog, its a heat blasting chip, and it sucks compared to amd chips.
something you must note this is VERY important. the speed in ghz between one chip versus another means NOTHING these days and it has not for YEARS. the pentium 4 chips at 3.2 ghz were slower in gaming then the amd chips at 2.2ghz. stock for stock. huh you say, its all about instructions per second. thats the bottom line. how fast the chip can work a set group of task instructions. former amd chips were the fastest. intel went and redesigned teh pentium 3 chip and the pentium M. the core 2 duo processors are based entirely on the pentium M's style of high use for low power and high speed and good instructions per second. the pentium M chips BTW on desktop boards with a retrofit kit was the FASTEST and BEST gaming chip until AMD ran out the opteron 939 chips. and still it was neck and neck. it was and is a killer chip.
AMD however is NOT the gamers chip either, sorry to those of you who believe so. but unless your only doing high memory bandwidth testing the intel C2d and Qx (dual core and quad core) beat the amd competitor (meaning same or cheaper price range heck even go up one level half the time) EVERY time. its simply the fact that intel has faster instructions per second times.
now for those screaming NUH HUH AMD FTW ....
well fanboi ? but seriously, the best amd systems are the am2 74 series and thats uber pricey. (processors are over 1k) intels quad cores are cheaper and preform as well and the qx6600 has been known to overclock and beat most am2 systems its price 266 bucks.... ill let you do the math.
when amd gets their 8 core chip out we will likely see this reverse, as amd has their memory controller on the chip and intels is on the northbridge, so AMD wont have a memory bottleneck to overcome with 8 processors trying to work in tandem.(hyper transport technology)
but bang for buck the intel core duo processors are fast, affordable and for those that overclock almost all of them easily have another 1000mhz in them on air cooling alone.
