am i right the amd athlon 64 x2 4800 is 2 cores running at 2400 making the total 4.8ghz.
also is the intel pentium d840 2 cores running at 3.2ghz making the total 6.4ghz.

if im right the intel is faster than the amd running at 6.4 compared to the amd running at 4.8


ps. im sorry to piss any of you guys off especially the administrators but i swear this is the last post il do about the dual cores!!!
 
my god how many times will it have to be reposted.

1) 2 dual cores running at 2.4 ghz ( or w/e) does not equal a double effect in terms of ghz or clock speed. so u do not have lets say, the equivalant of a 4.8 ghz processor

2) u cannot compare intel's and AMD's based on ghz, or any of the newer CPUs out..

Are you just coming up with reasons for the 4800 to run at 4.8 gigahertz? :rolleyes:

Dual core doesnt double the power, but allows the cpu to process multiple threads, speeding up performance in multitasking.

amd athlon 64 X2 4800 = 2 2.4ghz processors running simultaneously yeilding a clock speed of 2.4ghz, not 4.8!!

pentium D 840 runing at 3.2ghz = 2 p4 processors running at 3.2ghz yeilding a clock speed of 3.2ghz, not 6.4!!!

dual core does NOT mean dual speed, it means that your computer can handle two difference programs without any slow down, assuming you have enough system recourses.

There is going to be a little slow down on memory intense stuff, i mean they are going to be sharing the same memory bandwidth ;)
 
That's what dual channel memory is for.

No it's not. It will help (more memory bandwidth) but it's not designed to have 1 channel per core.
so the intel dual core @ 3.2Ghz means combined it runs at 3.2Ghz?
Click to expand...
Not really, it means it has 2 CPUs on the same die that are running at 3.2GHz each.

I didn't mean it like that.....

It's not like each of the channels are connected individually to each core. It doesn't have to be, as you will never have a faster memory bus than the CPU bus. It wouldn't matter if each core had their own memory channel, as long as all the data from the CPU bus can fit onto the memory bus.

The CPU bus limits the memory bus. Why build memory with a faster bus if the CPU is capping it?

Also, you don't think we magically received dual channel memory first, and then dual core CPUs later do you? These companies work together and get to test each other's products before we even hear about them.

"Of course, there are technical challenges in getting a dual-channel memory controller to work smoothly, handling data flows and keeping the CPU fed without traffic jams or collisions. While there's a ton of complex technical data available to explain the process, we'll give a broader overview here."

Having two process threads helps smooth the memory handling out. :)

Magic no, but dual channel and cores are completely unrelated. At the time dual channel came out the bus speed was way faster then any commercial ram module had any hope of running at (still is really, for an intel machine it's effectively 800MHz vs 400MHz ram, I don't want to go into AMD HTs) and dual channel was a way to 'double' (and I use double very loosely) the speed of the ram.
 
dual core does not means two cores running at the same equivalent clock speed of the single processor, advantage is that it can handle more processes at once. :) the only problem is that pentium dual cores are expensive. id go for the AMD any day
:cool:

Except the Pentium D is cheaper than AMD's x2. :rolleyes:

Price difference isn't as big of a factor anymore when chosing between AMD & Intel.
 
difficult to compare, amd and intel have different multiplier. unlike amd, cpu cores in intel are connected using fsb, which obviously affect the performance.

agreed. dual channel ddr is totally unrelated to dual core technology.

for dual core cpu, you won't be benefited if you are not running multi-threads program like me.

Absolutely not. The clock speed for the Athlon64 X2-4800 is 2.4Ghz. Period. The clock speed for the Pentium D 840 is 3.2Ghz

if im right the intel is faster than the amd running at 6.4 compared to the amd running at 4.8
Click to expand...
Wrong again. BUt you are correct in that the Intel one is faster

ps. im sorry to piss any of you guys off especially the administrators but i swear this is the last post il do about the dual cores!!!

I actually had a lot of fun in that thread until i accidentally deleted it.

Are you just coming up with reasons for the 4800 to run at 4.8 gigahertz?

Score points for marketing team ... you wonder why the Athlon64 X-4800 isnt 4.8x64x2 = 614.4GHz.....

That's what dual channel memory is for.
Click to expand...
Unfortunately thats irrelevant as they will be sharing the memory controller.

so the intel dual core @ 3.2Ghz means combined it runs at 3.2Ghz?
Click to expand...
No. Intel dual core @ 3.2Ghz means "intel dual core @ 3.2Ghz" and it runs at 3.2Ghz

The CPU bus limits the memory bus. Why build memory with a faster bus if the CPU is capping it?
Click to expand...
So what happens when the memory controller is integrated?

for dual core cpu, you won't be benefited if you are not running multi-threads program like me.
Click to expand...
Yes but you're running multiple programs :)
