Can I use Opteron to configure a desktop PC?
Is Opteron Underutilized in a Desktop PC Without 64-bit Windows?
Click For Summary
Discussion Overview
The discussion centers around the use of Opteron processors in desktop PCs, particularly in the context of whether they are underutilized without a 64-bit Windows operating system. Participants explore the differences between various AMD processors, including Athlon 64 and Athlon 64 FX, and their suitability for desktop applications.
Discussion Character
- Technical explanation
- Debate/contested
Main Points Raised
- Some participants inquire about the feasibility of using Opteron processors in desktop configurations.
- There is a discussion regarding the price differences between Athlon 64 and Athlon 64 FX, with claims that the FX is superior for gaming and multimedia tasks.
- Participants note that the Athlon 64 FX is sold unlocked for overclocking and utilizes a faster HyperTransport bus compared to the standard Athlon 64.
- Some suggest that the Opteron 1xx series could be a cost-effective alternative to the Athlon FX due to its locked nature.
- Questions arise about whether Athlon 64 processors are underutilized without a 64-bit operating system, with one participant asserting that not using 64-bit extensions means they are indeed underutilized.
Areas of Agreement / Disagreement
Participants express differing views on the value and performance of various AMD processors, particularly regarding the necessity of 64-bit operating systems for optimal use. The discussion does not reach a consensus on whether Athlon 64 is underutilized without 64-bit Windows.
Contextual Notes
Some claims depend on specific definitions of processor capabilities and performance metrics, which remain unresolved in the discussion.

Why Athlon 64 FX is more expensive than just Athlon 64 ?

In short, it's better.
According to AMD fans, it's simply the best CPU you can get for your PC. It was made for cinematic purposes - great for games, graphics, photo/video editing.
On PCWorld, the fastest PCs are always running the FX but they get lower ratings due to the higher price.

I've heard of small businesses doing this. The FX or basic AMD64 should have more than enough speed for tough computing tasks. If you want 64-bit technology, go with one of those.

Athlon 64, Athlon FX, Sempron, Opteron
If you want Athlon 64 speed, but don't need the 64-bit feature, you can choose the higher-end http://www.newegg.com/app/ViewProduct.asp?catalog=343&DEPA=1&submit=property&mfrcode=0&propertycode=&propertycodevalue=6355 which are basically Athlon 64s with their 64-bit instruction sets disabled (look for the ones that say, "FSB: Integrated into Chip" -- the other ones are just relabeled Athlon FXs).
Also worth mentioning is that the Opteron 1xx series is a cheaper (because it comes locked) alternative to the socket 940 Athlon FX.
The FX is sold unlocked for overclocking and also plugs into socket 940 which uses the faster HyperTransport bus. The Athlon 64 plugs into the old and slower socket 754, unless they are the newer more-expensive ones which use the new HyperTransport-enabled socket 939 (which also has the added speed advantage of not requiring registered memory). Also, some of the Athlon 64 models only have 512K of L2 cache.Saint said:

without 64-bit Windows, does it mean Athlon 64 is underutilized?

That seems to be a tautology. The answer is, "Yes. If you are not using the 64-bit extensions to the instruction set, then you are not using the 64-bit extensions to the instruction set. Generally, it might be said that if you are not using something then you are not using that thing."
