Do AMD64 (s939) have some sort of HyperThreading?

[Srek]

Nope, they haven't. Hyperthreading is an Intel only thing.

isn't HyperTransport something similar??... correct me if i'm wrong though, I'm a 32bit kind of guy. =) (go barton 3000!!)

No, HyperTransport is the interconnection between a bunch of Opterons or Athlon 64´s to the northbridge. More a data bus it is than the SMP-like behaviour of Intel HT processors.

hm.

the 64 bit support up to 4G of ram, i guessed u mean dual channel. the athlon CPU now supports dual channel in ram. this allows the data from CPU go through the two ram, which means evenly sharing the workload between the two ram. the dual channel ram must run with two ram installed.

it is not any kind of dual core, nor any kind of hyperthreading.......

:thumbsup:

search the post here about athlon 64 bit CPU here. more detail about the differences between the intel and amd CPU.

Ok, thanks all=
That's all I needed to know :) (y)

Actually Hyperthreading is not only intel thing. SUN and IBM will use Hyperthreading as well.

Can you provide a link to back this up?

[TraceR]

Yea, Isn't HyperTransport the same thing? I just ordered an AMD 64 3500 today. :D

As pointed out already, Hyper transport is the bus connection between the CPU and the Northbridge. Nothing to do with multi threading.

AMD's answer to HT will be actual dual core in a CPU package. 3Q of this year, we will see A64 proc with 2 cores. Should be more effective than HT, but then again, a P4 with dual core and HT will be out in about the same time.

[spirogyro]

so then which you say is more powerful? The P4 3.4ghz HT or an Athlon 64 3500+??

[azloha]

quite a number of tests had been done, the outcome is not that surprising, amd beat the intel. the 64 bit actually out perform the hyperthreading.

also, hyperthreading comes from the concept of multi core. hyperthreading is a technology my intel, simulating a dual CPU performance with one CPU.

any know the price a amd 64 bit dual core would be? i cant imagine......

[novadude]

Hyperthreading is merely Intel's way to feed extra bits of information through the P4's stretched pipeline. It is really just a hard coded instruction set telling the CPU to take bits of other calculations through at the same time it is trying to do another, making up for its extreme inefficiency.

I remember finding somewhere, also on ars I believe, something mentioning that HyperThreading isn't exactly new either :P Granted the P4 was the first to bring it to the desktop. I'll have to see if i can find that article

It seems AMD have gone for getting data 'through the door faster' to the processor and having fewer unused clock cycles.

While Intel have gone for slow data 'through the door' and some more 'through the window' to their larger number of unused cycles.

much of a muchness!!

If I was in the market I would get a real multiprocessor system. (Hmmm AMD or Intel?)
