I'm just wondering what type of professions and demographics AMD is targeting their Opteron and Athlon 64 CPUs toward. I have a vague idea, but wanted more from you folks. It's for a little research I'm doing- thanks!
Who uses, needs and wants 64-bit computers in the business world?
- Thread starter Stattlich
- Start date
I don't see the point for ordinary office use such as Office applications.
I see the point if you look at CAD, Simulations, database and 3D/graphics applications.

Anyone using any program that generates round off error will benefit from the increased accuracy.
Engineers Mathamaticians ect.
Error associated with succesive operations is significant. Decreasing this error will be an improvement.
I'm gonna try a 64 out with matlab and hope it improves the performace. I have only seen 1 review at toms that used a some sort of number crunching program as a benchmark. I'm not sure why they used such a pos program, maybe they couldnt write in matlab. Plus, its hard to tell what these results are from toms since the use of mathmatica generally outputs results to the screen, which is a huge waste of time and cpu. ( Don't complain about me dissing mathmatica ... it's a graphical interface not a command line and is intended to produce step by step results to the screen )
Once software comes onboard, computing potential will increase. It will be similar to moving from a 486 to say an early pentium chip ... wont it? Remeber when Dos booted and you had to type 'win'.

Anyone who uses oracle or similar database software can work a lot faster with 64 bit addressing.
Databases will benefit. And the most used backoffice application at any corporation/instituition? That's right - databases!
(okay, maybe intranet/web servers are the most used - but databases use the most resources. email servers are essentially databases too)

its like asking, "who really needs 32-bit cpu's in the business world? why not stick to 16-bit computing like back in the good ole days?" 64 bit computing has far more longevity and provides more options and better performance.

It's not an accuracy gain. When people need percision they will still use doubles. It's just now the computer can deal with doubles in a faster manner. Any program that extensively uses 64 bit floating point numbers (doubles) will get a big boost. Any time I write a program that uses decimals I just use doubles... but I doubt actually companies do the same.

Anyone who uses McAfee VirusScan Enterprise :evil: That is one hard-hitting (but thorough) antivirus software... home users with their fluffy little Norton or AVG have no idea 
Opening Access 2000 and then opening Access Help will stall even my A64 for about 45 seconds while VirusScan Enerprise clears the AC9MAIN.CHM file (called something like that) for usage. Celerons, uh, need not apply for this job. :evil:
The A64's hardware DEP (data execution prevention) looks to be a bonus for people, at work or otherwise, who use WinXP SP2. It nullifies buffer-overrun exploits at the hardware level. That's not related to 64-bit, but currently the only mainstream processor that supports this is the A64/Opteron family, and it certainly is attractive to think that our business computers would be inherently immune to a whole fleet of present and future attacks.

The place I work uses servers that have increadible load on them durring peak hours and the additional ram that 64-bit processors can address would really help the machines out.
Right its not an accuracy gain, as I have stated before. The accuracy is related to the order of opperations most closely. ( by order I mean is it O^n, n*n, n+1, ect ) But there will be gains in accuracy being able to carry more digits. I'm thinking of large matrix minipulation and differences showing up based on how many digits you carry.
Good words, guys- please keep them coming! I'm trying to gather as much informal data about AMD's demographic with these chips as I can. And for the record, I apologize if I came out sounding pessimistic about them. I'm a fan of these things as much as anyone and look forward to their market dominance shortly- just want to find out more. Thanks.
Old thread, I know, but at my work we're doing computational fluid dynamics, and the increased number of CPU registers that you get under AMD64 as opposed to IA32 really, _really_ help. Compiling our own source code, an opteron 248 under suse 9.1 pro 64-bit runs our code about 2.2 times as fast as a P4 Xeon 3.0GHz w/ suse 9.1 32-bit. While it's still faster than PenTel, we see about a 30% drop when running the same opteron 248 (2.2GHz) under the 32-bit version of suse 9.1. Mind you, this is using compilers that are more heavily optimized for intel platforms than for the opterons.
It's only a matter of time before the 64-bit additions will be more useful, but if you check out the linux world, they have been for quite a long time. A lot of SQL and Apache benchmarks under 64-bit linux completely blow away the performance of the 32-bit compiled versions, largely because of the increased number of CPU registers available under AMD64. Microsoft Office- no, I wouldn't guess that this or most games will be 64-bit for a long, long time, so it all depends on what you're doing.

Theres a good thread about 32 vs 64bit in this forum or highly technical if you search.
Anyway the biggest benefit right now is more memory than the current 2Gb limit of flat addressable memory. And we are getting close since many games already need 1Gb for optinum performance.

Who uses, needs and wants 64-bit computers in the business world?
ppl who wish to build a computer that is not obsolete 5 minutes afterwards..
could a program like SETI@home benefit from an opteron if it had sufficient bandwidth?
