PROCESSORS? Whats the difference?

Question

When i was looking at computers as i was customizing it. What is the difference between these two.

Intel® Pentium® D Processor 925 featuring two processing cores (3.00GHz 800MHz FSB, 2x2MB cache, non-HT EM64T) [ +US$0.00]

Intel® Core™2 Duo E6400 (2.13GHz 1066MHz FSB 2MB cache, non-HT) [ +US$80.00]

Why is the "2.13GHz" so much more expensive? Arent they both two processors?

Answer 1

the 2.13 ghz is a newer proccessor, the core is slower, but the other parts are much faster.

the D only has a 800 mhz front bus speed, this is the speed data can get to the core of the chip

the Duo has 1066, this is much much much faster.

this would be like having a fast little sports car that carrys 2 people down the highway fast. rather than having a 4 dore sadan which goes a little slower, but carrys twice as many people. in the end, the slower sadan does more work.

being that you will never max out the speed of these 2 chips for more than a second, data will get done much faster with the Duo because the bus that carrys data to the chip can get data to the chip much faster.

the D will spend more time waithing for data than the Duo.

im not sure if the Duo is a duel core proccessor, 2 proccessors built into one. if it is, then this is like having 2 sadans at the same time. each core can proccess data separatly. one app literly will run on one core, while another app runs on another.

i think that nowadays they have even made it so that one app can use 2 cores. half the app on one core, half the app on another, data gets proccessed twice as fast. as well as that data can get from the motherboard to the proccessor about 30 percent faster.

Answer 2

GHz is not a measurement for processor speed. The core 2 duo is a kick *** chip that is the best on the market. Also, the front side bus is extremely important, and the Core 2 Duo basically owns the pentium D at that. So get the core 2 duo, it will last much longer than the pentium d.

Answer 3

that's because the Core 2 Duo E6400 blows the Pentium D out of the water.

Core 2 Duo processors are the latest Intel processors and have a much better performance despite they are slower clocked.

yes, both have 2 cores but the Pentium architecture is obsolete now. in case you don't need that much processing power you can surely go for the Pentium D and save the $80.

Answer 4

Yes thats right, they are 2 processors. The principal difference is, that a multicore processor, is like having multiprocessors. What do i mean?, if you have a microprocessor with 2 cores, ur computer see it as 2 processors. 1 processor with 2 cores is capable to do more operations in the same time than 1 procesor with a single core. For that reason is more expensive. Sun Microsystems has a processor called SPARC T1, technology known as coolthreads, imagine the best SPARC T1 processor has 8 cores!!!!!!, and each core can attend 4 threads (single operation) at the same time.... so make accounts!!!, a single processor can attend 32 operation at the same time. A single core with not multithreading can just attend 1 operation in the same time. I hope that i have been not so confusing.

Best regards!!!

Nice question by the way

Answer 5

Clock speed is not what matters, efficiency does, along with the interface with RAM through the FSB.
I've plugged them into this comparison chart, look and you will see the difference. You can look at other benchmarks as well.

Edit:
Michael c cardinal, AMD cores do not "duel", it wouldn't be good for them to fight. AMD lost the crown when Core 2 Duo came out. I've used AMD for years, but this is the reality.

Answer 6

M is for mobile meaning the processors are only meant for laptops... number before that just represent the model number..generally speaking,higher the model number, better it will be..but in i3 , the difference wont be that significant..

Answer 7

The only issue I see is that the second, slightly more expensive processor is 'synchronous' - that is to say the processor is an exact number (2x) the speed of the FSB (front side bus)... this generally improves performance.

I'd like to see more details on the systems, as the price difference is odd - and I'm curious as to why both are non-HT (hyperthreaded).

Answer 8

the core 2 duo for overall performance
the cheaper one is for speed and not much else. get the core 2 duo

Answer 9

More GHz does not always mean "faster". The Core 2 Duo has a faster FSB and memory.

Answer 10

Run a comparison on Intel's web site then go to AMD they run fast and cost less they also run a lot cooler and they make a better gaming pc. I use Intel for some pc's I build ( Power pcs) but I use AMD for the real gaming and and Cool running pc's. But either way run a comparison check and compare specs...I mean a detailed on.. Core names...FSB speed...Cache size etc..
