AMD's Hypertransport Facts!

Q: How Fast Is Hypertransport?

A: 6.4GB/s. Did you know that hypertransport is 48 times faster than the methods used in the KT133A chipset, 24 times faster than the methods used in the KT266A/333 chipset and 12 times faster than a chipset called KT400 which isnt even released yet by VIA.


Q: Why Hypertransport?

A: Simple, you wouldnt want your CPU to wait simply because the connections to your northbridge and southbridge become congested so thats why hypertransport is used. Tests show that VIA's newer V-Link technology still does not cut it especially when using a RAID setup. Todays PCI sound cards can easily require high amounts of bandwidth infact near 133MB/s in the most intense surround sound cases (EX: EAX-HD).

To break down even further, think of it this way. Say you own a KT266a chipset, which means that everything you do on your PC internally is basically limited to 266MB/s total. That means, your hard drives, USB, Sound Cards, Ethernet cards and soo fourth all share that 1 amount of bandwidth. You can forget about Gigabit ethernet cards if you have a KT133A/KT266A/333 since the ethernet card it self could almost swamp that little bit of bandwidth.


Q: Who Uses Hypertransport?

A: Currently only nVidia has tooken advantage of hypertransport. VIA has also issued support recently for hypertransport but this technology with VIA will not be availiable untill K8 Clawhammer technology appears.


Q: Who Invented Hypertransport?

A: Simple, AMD invented it!

Is this integrated in the nforce2 chipset?

Yes!, thats why AMD was as excited as nVidia was at the launch party. They were glad to see Hypertransport technology (K8 technology) being used in nForce2 with AthlonXP!

Somebody hates VIA...
I want a clawhammer now :cry:

VIA has been good, hence my PC has a KT133A in it, but I dont respect VIA the same way that I have two years ago.

I think It's time to go nVidia with new innovations unlike VIA who thought they did something special by releasing a KT333 chipset.

KT266A to KT333 was just dumb waist of time. KT266a performed just fine and KT333 added very little if not no performance improvement. And plus most people ran PC2700 on there KT266A boards anywayz.

My next PC will have dual channel DDR, thats all I can say.

The KT333, while not a huge speed upgrade over 266a, was still a very good move. KT333 introduced the /5 divisor, for FSBs over 166

Well gigabit ethernet supports at maximum 125MB/s transfers. The PCI bus supports 133MB/s. So really the bottleneck will be the traditional PCI bus before the northbridge. Of course, you're right, 266MB/s on your memory bus isn't helping things any.

Erm, this has been in every nforce1 chipset and isn't exactly news, but mkay. Just another chance for me to dream about a 12.5GB/s direct-to-CPU network tap.

exactly,

plus wouldnt you want a PC that can talk between the Northbridge and south bridge at 6.4GB/s rather than 266MB/s?

Sounds good.

So did the nForce.

Are there any working models of it yet?

Yup, ASUS has a few prototypes that work :rolleyes: but of course no-one around here has one yet :(

nForce was an OK chipset, nothing wrong with it just like with the KT266/333. The only thing the nForce had wrong was that nVidia had a little too much latency on the memory infrastructure which costed it the first place ribbon in terms of performance. Appearently they have fixed it, I guess only time will tell!

Its just that I wanna see some speed laid down onto AMD's CPUs. I just know these new chipsets will excel in that department.
