AMD to use HyperThreading?
 
Quote:

AMD patent could enable hyperthreading

But will AMD do it?

By Adamson Rust: Tuesday 17 December 2002, 10:17

OVER AT THE US trademark and patent office, there's a slightly elderly patent successfully filed by AMD back in 1999 which indicates that the firm could provide hyperthreading for its processors, if it should so wish.
The patent, numbered 5,944,816, entitled "Microprocessor configured to execute multiple threads including interrupt service routines", outlines how a CPU can execute multiple threads concurrently.

It specifically says that in one test, a CPU executed at least two threads concurrently.

The patent builds on a number of technical documents on simultaneous multithreading, including an Intel document from 1994 called Multiprocessor Specification.

So will we see a hyperthreaded Clawhammer (Athlon64)? Well the patent seems to suggest that's not outside the bounds of possibility.

You can find the reference here. ยต
This could give AMD a serious workstation performance boost.

Hyper threaded dual 248 Opterons :p. I so want my dual Opterons.

Way to go AMD! ...Although I won't be able to make much use of it, AMD=Stricly gaming for me.

technically old news, but new to me.

I think AMD should go for it. Anything to open up a wider audiance for their processors instead of the majority chip buyers being just gamers.

The next wave seems to be CPU's that will be dual core and 64-bit, so if your looking to purchase a new computer I would wait it out another year or so, for significant changes in computer architecture.

Intels Near Future (Bye Bye P4 hello dual 64-bit P-M)

Follow the leader to 64-bit :p

2 P-M's on one die

AMDs Near Future (Cont moving in the right direction):up:

Already has 64-bit, but dual cores soon

"Microsoft is expected to recommend that the "average" Longhorn PC feature a dual-core CPU running at 4 to 6GHz; a minimum of 2 gigs of RAM; up to a terabyte of storage; a 1 Gbit, built-in, Ethernet-wired port and an 802.11g wireless link; and a graphics processor that runs three times faster than those on the market today." :confused:

Longhorn isn't supposed to come out in a few more years. As for the RAM, it shouldn't be too hard with DDR2.

Sun have had dual-core processors for a few years now, in production for about 1 year though, they also have an 8 core chip in development. AMD aso have a dual core processor in development so I doubt they'll switch the single core Athlons to HT. However, if they incorporated it into both of the dual cores, that could be interesting.

whiteflip 26th June 2004 05:09

thats kinda what i was saying. dual core and dual proc. so four cores in total. but wouldnt a tri core setup of some kind be more effective? one processor to delegate tasks to the other two processors below it? im not an engineer of any type so i wouldnt know if it would be a good idea or not.

k_rock923 26th June 2004 05:17

Damnit. Just when I make myself a new computer, PCI express, DDR2, multi-core processors, 64bit processors becoming affordable. . .ugh. Whatever happened to BTX? Did it kind of fade away?

Starbucks 26th June 2004 07:20

BTX is an Intel thing and is still on its way. It's really unnecessary if you own the new Lian-Li PC V1000 case, or if you have an Apple.

As for dual cores, I'm pretty sure Intel will try to pack as many features as it can into the dual core P-M. It should include Hyper-Threading on each core, because Intel has already demonstrated that a dual system with H-T is a virtual 4 CPU system. A dual core dual CPU system would yield a virtual 8 CPU system, or at least the theoretical performance of an 8 CPU system without an 8 CPU system price.

BTW, IBM has 8 cores on 1 die with really fast level 3 cache. It's a monster.

I really really like the mainstream dual core idea. Bandwidth used to be the biggest problem in IT, now it's only secondary to latency. Dual cores have ultra low latency, so a system with 1 cpu and 2 cores can perform at near 100% faster than a system with 1 CPU. that means each CPU can work at full speed. Today's dual systems only work 60-80% faster than a 1 CPU system.

To make a dual core cpu a real idea, Intel and AMD had to consider than they will use twice as much space on a wafer than a single core die. That means they will have X yield number times 2, or twice the amount of bad yeilds. Both Intel and AMD will end up with a lower profit margin (for dual core CPUs) because of this. Better for the customer as always, which is another reason why I like dual cores.

so much that you know that i didnt but now do.
