AMD and Hyperthreading???

I posted this question originally in the articles forum, but thought it would be valid here and get more views.

I noticed the Gigabyte GA-K800A Hammer board says it "Supports Hyper Threading Technology processor." Is this a typo, or will Hammer support HT and I've just been under a rock somewhere? 😕
 
well it definitely is a hammer board by looking at the pinholes and the amd chipset...

hmmm i did not nkow amd had anything about hyper threading going on....
maybe someone will clarify whether its a typo or provide a link to amd hyperthreading?
 
Unless I have been living under a rock, Hyperthreading = Intel, AMD has nothing to do with it as of now. But I guess it is always a possibility, but I don't think Intel would license that tech.
 
i think its safe to come to one of the following conclusions:
1) most of us have been living under a rock 😉
2) its is a blatant typo/mistake

...im leaning towards number2, but im not too current on everyday news so maybe someone will show up proving us wrong
😱
 
I'll submit in alternate explaination just for variety 🙂 Perhaps they are referring to the board's MP CPU support capabilities and unwittingly or by design worded it that way 😉
 
Since Intel likely has HT copyrighted, I HIGHLY doubt that AMD's using it, unless they want to get put under a rock by a lawsuit.

My bets are Gigabyte simply confused HyperThreading with HyperTransport.

Marketing people make a lot of mistakes. That looks like a copy and paste from their Intel board offerings.

When I was a Hardware Engineer at Hayes modems I worked with the Marketing Dept a lot to make sure they didn't let mistakes out like that, they are not Engineers, they are Artists.
 
LOL, I seriously think its a MAJOR TYPO! look at that picture, there is yet another type right at the top of the sign with the features,
It says 800mhz FSB for Hammer processor! um.....most hammer is gonna support as of now is 400mhz that I am aware of.
So, yeah I figure both are typos
 
well hrm...now I am all sorts of confused.
Hammer TECHNICALLY doesnt have a FSB except to the AGP tunnel.
cause the memory controller is built on to the processor.
if I was mistaken and there is something that is 800mhz someone let me know, it will be news to me lol.

HyperTransport runs at 800MHz and is "double pumped," meaning data is sent on the upswing and the downswing of the clock, doubling the effective bus speed to 1600MHz.
 
I still dont think that is considered as the FSB though...thats hypertransport. Cause, the FSB was always considered what communicates with the northbridge chipset.
In the hammer this is no "northbridge chipset" there is the AGP tunnel and its hypertransport to the southbridge, and the CPU communicates with the AGP tunnel yes through hypertransport, but I sitll dont consider that the FSB...cause the FSB I always considered as a big factor in memory perforance, therefore I dont see there being a FSB anymore cause the memory is directly hooked up to the CPU...Thats just how I view it though.

Like, the FSB was always focused towards mainly communication with the CPU to memory through the northbridge.
But now, only thing is the AGP its hooked to the CPU, and I dont see AGP nearly as reliant on FSB as memory was.
So, to me there is no more FSB lol

if you get what I am saying. Its all wrong but...ya know
 
Actually, I've heard rumors of AMD allowing you to disable the onboard memory controller and use a northbridge, like you would in other chipsets.
 
why exactly would they give you a choice to do that when all it would to is increase the cost of the mobo manufacturing? And also, why would they want you to decrease the performance?
 
I know it sounds confusing because this is new technology for a change. But it is a "Bus" sort to speek. The current bus for the Athlon is the EV6 bus @ 133/166MHz DDR. The one for the Hammer will be called HyperTransport @ 800MHz DDR. It does have a "Northbridge" but its just that the memory controller will be on the CPU.
 
Intel didn't invent hyper threading so no license or patent issues would keep amd from implementing a simultaneous multithreading. A couple of other companies like Sun already have "hyper threading" on chips they make.

They could have the same essential function, but I highly doubt it's called "Hyperthreading."

Integrated graphics cores come to mind. Since the integrated graphics need access to system memory too, adding a northbridge might be the lesser of two evils, versus making the CPU spoon-feed the GPU whenever it wants something from memory.

Precisely Mech, that is why Nvidia has a MB with onboard GPU and without. The board without will outperform the board without for exactly that reason. ASUS did it with previous generations, others are just doing it too now.

EDIT - Hey Mech, just as I posted this saw this Posted by Anand and Co from Comdex:
Nvidia unveils K8-supporting single chip
November 22nd, 2002 4:43 PM - Brandon Hill

Category: News


DigiTimes has some fresh info on NVIDIA's new single chip AMD K8 chipset:
Nvidia?s new K8-supporting chip for the Advanced Micro Devices (AMD) platform, the Crush K8, will come as a single chip solution with the AGP controller interface integrated into the south bridge chip (media communications processor, MCP). Nvidia demonstrated the product for the first time to certain customers at Comdex Fall 2002.
With AMD incorporating the formerly north bridge-based memory controller into its upcoming K8 processors, the role of the north bridge chip will become rather limited, Drew Henry, Nvidia?s senior director of platform product management said. As a result, Nvidia decided to include the AGP controller interface in the south bridge to shorten motherboard makers? design time, he added
