Reverse HyperThreading. So simple, yet SO effective. :thumbup:

[Shaman]

This is good stuff. Worth waiting for since LockOn is not dual-core ready.

[Mustang]

This is exactly what LockOn needs, when this becomes available i'll be upgrading for sure!

[Pilotasso]

I already suspected that the fuss in the market lately would make an upgrade a bad idea right now. If this technology wroksa as advertized it should blow everything else out of the water. Ill have to wait another year for this though.

Well, I already got an X2 4400 so I'll be updating drivers etc when they're available....I currently use procaff to put LOMAC on one CPU...which still gives me 20-50fps online and 35-50fps offline (I run at 1024x768 cos I use a projector, 2QxAA and 16xAF).

 

I'll be happy with any boosts in performance I can get...and for free ;)

And it iwll not work on socket 939?

[dynamocl]

Doesnt mention 939 does it. I know they are stopping production on 939 soon, so I would imagine that the feature will not be on 939, unfortunatly.

Socket 939 was the first platform which supported X2 CPUs - it stands to reason they might give us 2-to-1 support as well. :smilewink:

[Roman G]

Unfortunately this is just rumor with no detail whatsoever how it would work.

 

I will believe it once I see it ...

If this theory works already for 40% then this AMD 4x4 platform will boost up lockon like a rocket.

 

But how about an IBM processor of 1000 Ghz:

I hope AMD is not panicking about Core Duo and forgetting about socket 939 customers. Core Duo is good, however, for me to go to Core Duo, I will need new motherboard, memory and CPU. So, AMD could keep me as their customer if Anti Hyper Threading will work on socket 939 dual core processors. If not, I might just go for Intel. I don’t really care for brand name. I look for performance and value.

Any idea when AMD is likely to announce this officially?

 

Intel Conroe is due for release in 2 weeks.......

[Jay]

I don't think they will announce this officially before Conroe comes out. They'll wait and see what Conroe is all about, and then prepare the best marketing strategy for this new technology. We'll have to wait and hope...

I do not believe AMD is actually putting Reverse Hyper Threading in its core logic. The core pictures of socket 939 and am2 just don´t diver enough to contain reverse hyper threading stuff.

 

Besides that, with the current, and actually very quick, move to dual/multiple cores, software developers are already adapting their software to parallel processing.

 

AMD did release a little piece of software to fix some issues that some games have with dual core CPU´s.

Does anybody know how this magic reverse hyperthreading buzzword works ?

 

I am programmer, 95% of code I write is multithreaded, but I really cannot imagine how two cores can process a single threaded program faster than a single core (apart from some asynchronous stuff - but asynchronous processing is essentially not a single-threaded program) ...

 

I am affraid a lot of people on this thread are putting their faith in a rumor ...

 

I would like to be proven wrong, but I am quite confident that in this case I wont ...

The AMD trick is rather shutting down core 2 programmatically while overclock the first core.

(2 cores can’t run on max OC because of heat) Programmatically core 2 starts up again if necessary and core 1 will run again on a lower OC speed.

 

I don’t know what kind of programs that you write but except for launching a print-job or an export (another thread can do the job while the main program don’t have to wait for this) of data but I can’t see why 1 single business application needs multithreads for.

With a game/sim it is another story. 2 multithreaded modules using the same memory without blocking each other is a hard job for the programmer (for example an AI logic module running on 2 threads).

Just to enlight you, Sonny, each web server runs many threads (tens of them). Each web request is handled by separate threads. So if you are writing any web applications (which I am not) you in fact need to be aware of threads (unless you are doing something really simple like static pages).

 

Each meaningful web browser runs multiple threads. That way it can download images separately from web page text.

 

Each meaningful database engine is running multiple threads. Otherwise your database query would have to wait until my database query ends.

 

Even simple slideshow viewers run multiple threads. While one thread handles user input and displays images, other threads are prefetching next images so when you hit the "next image" button the already pre-loaded image is displayed instantly.

 

The list goes on and on ...
