A64

A64 may release in 1st quarter 2004. They are having problems going past 2.0 Ghz.

I think the main benefit is more than 64bit math. Especially since the default operand size is 32bits. I think most of the benefits will be seen from the 16 extra registers (double the current amount) and the low latency memory controller.

It does need to be at a competitive speed and after looking at the <A HREF="http://www.xbitlabs.com/articles/cpu/display/athlon64.html" target="_new">xbitlabs</A> article 2ghz+ is necessary.

I think it needs a <A HREF="http://www.tech-report.com/etc/2003q2/athlon64/index.x?pg=1" target="_new">dual channel memory controller</A> to keep up with the P4. Then again, the Athlon has done well so far without a dual channel controller. It does seem that you need 5% here and there just to stay competitive.

I'm guessing <A HREF="http://www.theinquirer.net/?article=9216" target="_new">TheInquirer</A> article is the basis for this thread.

Dichromatic for your viewing plesure...

The extra registers are all 64-bit, I don't understand why the performance boosts when enabling 64-bit, could come from these expansions than 64-bit computing itself, as imgod2u stated, if from what I've seen of these reg., they are all 64-bit and not 32-bit.

The 64-bit instructions were a decent idea for a company such as AMD. They do not have the market share to move anyone to a new instruction set. Intel already has a 64-bit processor with a new instruction set and will not license it to them. Their only option is, indeed, what they are now doing. It's not so much vision as it is the only step they can take to enter the 64-bit market. You do what you must do.

Where I believe they made their mistake, and only time will tell, is to sell 64-bit silicon to the home market at this point in time. While others are using that silicon to speed up 32-bit operations, offer more cache, etc., AMD will be using a large portion of it for 64-bit operations that will go largely unused in most home systems for a very long time. That silicon could have been put to better use. As it stands currently you will be paying for that portion of the processor whether you use it or not. Perhaps they could not afford to maintain a separate 64-bit processor line. Who knows...

They can use as a 32 register the same way I2 can use there 82 FPU reg for 32 ops on FPU

64-bit extensions on AMD's silicon take no more than 10%, this is by no means a waste of our money Ray. It's in a fact a near-freebie. And they are not advertising 64-bit for the desktop, they will for server, but home users will likely not have that advertising. If it does, who cares, if you got Win 64-bit like 2003 Server will support, you will have support and be using some 64-bit despite not using the real amount that 64-bit can do.

It is already a powerful CPU, the Opteron at 32-bit is a powerhouse, and has sometimes IPC over 40% per clock. How in the world you see that as a silicon who has some wasted space is beyond me.

WHO i nerver say that IA-64 register is the same model that A64 far from it.

I was just saying that you can use the extra reg without 64 data.You can store 32 data in the new reg as long the code is recompile.

[-peep-] french

is all 4858 bit or any others wide register can allwayse be use as 1 32 bit reg like AMD64 or IA64.

Also FPU reg in Ia64 also have 32 static and 96 rotatif

Wait a minute. The Clawhammer version of the core was named Athlon 64. So name in it self is a big advertising saying it's a 64 bit processor.

Last ligne nothing you were saying that on Int or GPR that there have 32/96 setting i just make sure that everyone know that also the case of FPU.

There's a rumor out there that we'll never see A-64. I think Inquirer started it. Essentially, the rumor goes that AMD will just push the Opteron as a desktop processor since it performs so much better than A-64 will...

A good idea if you were on 300 mn wafer but AMD capacity of production is 1/10 of intel or Samsung.They will need to outsource a lot of production to IBM or TCMS.The 1 become will be the 1 contender.

Also the full 128 bit mothers will cost a lot deleting any capacity to run on Mobile or low cost or small case.

Option nb 1 is to disable the last controleur and flexibility issue appear greately.As Opteron and A64 wont use the same memory as DDR-2 should be use in sever only very late compare to desktop so you wil need a controleur for DDR1 and DDR-2 by the way not put QBM and RDRAM and SRAM.

Actually juin there is a rumor that the 0.9 version of Opteron and A64 in the first half of next year will include a ddr-II controller

Well thats the rumor, and remember IBM is helping AMD with its manufacturing so it isnt too far fetched

Maybe with IBM's help they will have 90nm by end of next year. Thats when A64 will be released finally!!!!
