64-bit apps / running at 64

[gooberguy]

I have amd 64 3000+ that i got recently and was wondering is there anyway to run 32 bit apps in 64? or are there that many 64 bit apps out there?

Thanks for the info.

if your OS is 32 bit -- all your apps are 32 bit also

the amd64 is not a true 64bit cpu ..

to run 64 bit apps - you will need a 64 bit operating system ...

and in terms of 64bit apps for windows -- no , not that many yet ..

You can download a free one year trial of Windows XP 64 bit from Microsoft.

I believe there are now a good number of programs that are 64 bit, although I don't think performance is improved that much.

you will also need 64 bit drivers for all your hardware for them to work in 64 bit operating system.

a lot of the whole 64bit thing is marketing also -- and the ability to sell you something you dont really need -- but are going to buy ....

there is also a little (lot?) of this going on also

That almost looks like LS in a costume.

ATHLON 64 is a REAL 64 BIT processor. But because Intel was`nt able to release a 64 bit version CPU you have to use a beta version of windoze: WINDOWS 64 BIT whitch can be downloaded for free from a location you can see higher shown by : 888888 , an old member of this site. You must search for drivers in 64 BIT for video & audio card at least, on internet. Soft also in 64 BIT must be downloaded and there are enough for now. The most convenient way to compare the power of 64 BIT is to have 2 identical HDD in your computer and install on them 2 windowses : one with WINDOWS XP PRO SP2 and one with WINDOWS 64 BIT(beta). This way you can see the difference of the two OS, and still enjoy the other programs(and games) that don`t have 64BIT support (on Win XP PRO SP2).

ATHLON 64 is NOT a REAL 64 BIT processor -- crips do some research please .. Im not saying its a bad cpu - I just hate to see misinformation ..


And intel had a real 64 bit cpu before amd ever did - the 64 bit xeon .... though it never really sold very well BECAUSE IT WAS A TRUE 64BIT CPU AND DOESNT RUN 32 BIT CODE LIKE THE ATHLON 64 (it was also way overpriced)!!



you cant really compare two os's anyway - the way you describe .. for a variity of reasons ...

[adam]

Could you explain BJ_M cause I'm clueless on this. What makes the Athlon's less than a true 64bit processor?

I always thought that they were 64bit processors that were backwards compatible with 32bit applications. With a 64bit capable os, software, and drivers, won't these chips be able to operate at 64bits?

SPARC, POWER, PPC, MIPS, ARM, IA64, Alpha, Elbrus, Fujitsu, all are/make/made 64bit true cpu's , the IBM's System/370 used 128-bit floating point numbers in fact ..


saddled with ancient x386 code, amd64 was wisely designed to run both 32bit and 64bit code , but even at 64bit - its not the same 64bits as used on most of the cpu's above .. as for the reasons its not a 100% true 64bit cpu -- it is a fact based on the way it was designed --
as i said though , i'm not knocking it at all - great cpu .... wise marketing also to support x386 32bit code ....

trivia - intel had secret pentium pro cpus ~8 years ago that were full 64 bit -- but had no support (or OS to run) to produce them and the project was dropped -

And intel had a real 64 bit cpu before amd ever did - the 64 bit xeon ....

That was the Itanium, mate. I don't think it was ever considered a Xeon. The Xeons with EMT64 extensions came out last June.

From what I hear in the SMP world the reason all current "64-bit" consumer chips are hobbled is because they do still contain 32-bit architecture and instructions. This is basically comparable to having to run an emulator on-die pretty much all the time. The new architecture certainly helps 32-bit performance at times but it will hinder 64-bit performance when its time comes.

I don't see a very easy transition to 64-bit when it comes, which I don't think will happen for several years. All this cloak and dagger stuff is making my all giddy though

[BJ_M]

intel marketed the Itanium as a Xeon when first came out --

they are now to go wit blending the xeon w/ 64bit instruction set (Intel EM64T) that they make now w/ the Itanium to make the Itanium 2 ..

i really dont know if this will fly - or if intel really has a clear road map ahead

However, that is not to say the Itanium processors aren't selling. Intel said it has tallied ten times as many server shipments over the last year with three times the revenue. The company also boasts that 38 of the world's biggest 100 companies use Itanium, including cereal maker General Mills and consumer product maker Procter & Gamble.

ntel executives, including COO Paul Otellini and CTO Pat Gelsinger, have noted indirectly that Opteron's momentum has upped the pace for their own enterprise roadmaps.

"We had some fumbles and so we went back to the basics," Otellini said. "I'm happy to see that our competitor is also adopting a multi-core strategy because it validates our choice. This is not the same race it has been. We're moving back toward a consistent, rigorous and conservative production schedule."

One bright spot Intel managed to point out is that when Itanium is present, it makes its presence known. The chipmaker is supplying NASA with 10,240 Itanium processors for a SGI system running Altix that should finally unseat the world's fastest supercomputer -- NEC's Earth Simulator.

Intel said its dual core road all starts with its 90-nm dual core Itanium processor, code named Montecito, with a 65 nm process follow on, code-named Montvale, and a low voltage variant available next year called Millington. In 2007, Intel said it expects to release the multi-core Tukwila chip and its low power counterpart Dimona.

The first two multi-core Intel Xeon processors based on the 90 nm process, are codenamed "Cranford" and "Potomac," and are expected in the first half of 2005. The products will include Intel Extended Memory 64 Technology (Intel EM64T) and Demand Based Switching with Intel Enhanced SpeedStep Technology. They will be supported by a new four-way chipset, codenamed "Twin Castle," that supports PCI Express and DDR2 (define) memory.

The company said its multi-core technology is expected to arrive in high-end systems with a dual-core Intel Xeon processor codenamed "Tulsa."

Farther out on the roadmap are a multi-core Intel Xeon processor, codenamed "Whitefield," and its multi-core Itanium 2 processor counterpart, codenamed "Tukwila." Whitefield will share a common platform architecture with Tukwila.

For two-way servers and workstations, Intel announced "Irwindale" as the codename for a follow-on processor to the recently introduced Intel Xeon processor at 3.6 GHz. Irwindale is expected support a faster clock speed and larger 2MB cache.

Talwalkar also said future Intel enterprise products will incorporate other already disclosed silicon technologies such as the server version of virtualization technology, code-named "Silvervale," which will allow for partitioning and other security and reliability attributes.







* personally i think that intel will rethink part or all of this road map ..
