64 bits - Opteron - Cinema 4D

[Srek]

Hi,
Windows XP 64 is only available for the Intel Itanium. An Opteron version has only been announced recently afaik.

You can't compare OS X and XP 64 since OS X runs on the same hardware as OS 9, whereas for XP 64 a complete new hardware is neccesary and the 32 Bit emulation is slow compared to fast 32 Bit system. Also XP 64 lacks a number of features XP 32 has, macking a fast transition form 32 to 64 bit unlikely.
Don't get me wrong, a 64 bit OS is godsend for 3D, if it were only for the hugh amount of adressable RAM. :drool:

Cheers

Fortunately, the Opteron is not only a 64 bit processor, it is also a very fast 32 bit processor, unlike the itanium. 32 bit Cinema4D should run very nicely (i.e. better than on an Athlon or P4) on the Opteron.

not wanting to ruffle any feathers , but have you any evidence to back this comment up?

how do you come to this conclusion?

ive not seen any test results that could define the 32bit mode for this cpu as slow or "slower than"

Microsoft said that win64 will run in an opteron hardware

I think features are not important, I only need to rule the software. I have see database benchmarks 32 vs 64 and improvement is amazing, also you can run 4 or more CPUs in one computer :applause:

Hi,
Paul: You may be right, i haven't got that much information on the performance
Omnibus: Database and Rendering Performance are completely different animals. Xeon processors can already be combined to multi processor systems. Don't expect the multi opteron or multi Itanium systems to be cheaper then multi Xeon systems ;)
I had a look at the IBM website where they offer Multi Xeon system and came up with this beauty :eek:

X Series 255
4 x Xeon 2 GHz
1 GB RAM

And for a bargain price of only 27.000 $
Time to kill the piggy bank ;)

that may require several piggy banks :)

If these rumours are true the next OSX on PPC970 (64 bit) will be a quantum leap for mac 3d users. Wait until june/july

I think you'd be wanting more than 1Gb RAM with those four processors! :)

well in the early days of this I also heard this was the case...whether this is still true is another matter.
:shrug:


just to add to the mix...what about linux? hasn't that been 64bit for awhile now...:shrug:

[tapaul]

I just read in C`t that the 1.8 ghz opteron is a tad slower than the 3.06 Ghz p4 !!!

think about that :)

1.8 ghz is a tad slower than 3.06Ghz.

in emulation mode !!!!

so when AMDget there act together , a 2ghz+ opteron should be way faster than any 3 ghz intel component.

This is from Microsoft's website:

Windows XP 64-Bit Edition includes both 64-bit and 32-bit versions of MMC. The default version of MMC that runs in Windows XP 64-Bit Edition is the 64-bit version. You can, however, manually select which version to run by running MMC from the Run dialog box, and by entering runtime parameters. This might be necessary if certain MMC consoles that you need to use are not available in a 64-bit version.

To manually select the version of the MMC to run

To run the 32-bit version of MMC, in the Run dialog box, type mmc -32.
– or –

To run the 64-bit version of MMC, in the Run dialog box type mmc -64.

Just to clear things up for the record:

>>1.8 ghz is a tad slower than 3.06Ghz. In emulation mode !!!!

The Opteron does not have an 'emulation mode'. It is a true X86 processor, and runs all 32 bit code natively (as well as 16 bit code, obviously). The Itanium (Intel's 64 bit chip) runs 32 bit software in emulation mode because it is not a true X86 processor - it is a completely different architecture. This is why 32bit performance on the Opteron is great, while 32bit performance on Itanium suffers. The Opteron uses an approach similar to the way 16bit versus 32bit work currently on the X86 - only now there's 16bit, 32bit, and 64bit modes, and they all play together at the same time quite nicely.

[tapaul]

since when is the opteron now a native 32 bit cpu?
it was hammer and has always been talked of as 64 bit with 32bit emulation.

where have you read that opteron is a 32 bit cpu as apposed to 64 bit?


id like to see the link please.

this seems to clear things up

I believe the Opteron is a hybrid processor, able to handle 32 bit and 64 bit natively.

Bottom line to me is that it's slower than 3gHz P4 or a dual Xeon running over 2.2gHz. *If* AMD can ramp up the clock speed it might be a viable choice.

[flingster]

no one mentioned cost yet...:eek: (apart from the 27000!)
xeons are fast we all know that..but what about a fair cost comparision.
