én csak annyit tudok, hogy az athlon 64 és az opteron majdnem megegyezik, kivéve hogy az opteront szerverbe szánják -> kisebb energiafelvétel (talán), stabilitás az elsö (husszútávú stabilitás, mert a szerver sokat megy 24/7) ami különbség lesz még, hogy az opteronba a memoriavezérlö is valami kutyakaki egy szo mint száz, az opteron lassabb lesz mint egy athlon 64, s szvsz drágább lesz. ki akar venni drágábban lassabb gépet*?

''Also keep in mind that the motherboards we're testing with are not tuned for extracting every last ounce of performance, they are setup for stable, reliable, 24/7 operation. Overall performance will be higher on nForce3 Pro boards aimed at the enthusiast market as well as Athlon 64 motherboards once the chip is released. ''

''The Opteron still has the disadvantage of running on a serverboard, which is tweaked for stability and which will not use aggressive memory timings. It also runs with ECC memory, which will further decrease performance slightly. But we can get an idea what the raw CPU gaming power will be. Of course, if the AGP tunnel of the AMD64 platform proves to be less or more efficient than the one of the Pentium 4 chipsets, this may influence the final gaming results as well. ''
Mi a különbség az Athlon 64 és az Opteron között?
Athlon-64: 754 tüs
Opteron: 940 tüs

ebböl kiderül hogy maximum 68C fokos lehet a Clawhammer, az Athlon-64 processzor. Az opteronnak alacosnyabban kell müködnie, ezt a Prohardveres hir is mondta, hogy a szervereknél fontos az ''hidegfejüség''. Ez elképzelhetö ha az Athlon 2ghzen nyit, az Opteron csak 1.8on marad.

Q: What are the differences between the AMD Opteron processor and the AMD Athlon™ 64 processor?
A: The primary difference between the AMD Opteron processor, for servers and workstations, and the upcoming AMD Athlon 64 processor, for desktop and mobile systems, is in the number of HyperTransport technology links embedded on the chip. The AMD Athlon 64 processor will contain one HyperTransport technology link offering 6.4 GB/s data transfer while the AMD Opteron processor offers three links. The processors may contain different amounts of cache depending on the configuration a customer chooses.
most mindenki máris letudta, hogy az Opteron a jobb, de nézzük meg mit tud az a 3 HT?
Anandtech:
While the desktop Athlon 64 only has a single Hyper Transport link, each Opteron CPU has three links - two for connecting to other processors and one for connecting to I/O bridges (e.g. South Bridge, PCI-X bridge, etc…).
Tehát a többprocesszorosdit támogatja meg.
Mi is van még: Az athlon64 memoriavezérlöje 64bites lesz (DDR II), mig az opteroné 144bites, de csak ECC ramokat támogat az opteron.
Aceshardware:
''With the data I have right now, I think we can speculate that an Athlon 64 1.8 GHz will perform more or less like a 2.8 GHz - 3 GHz Pentium 4. The Opteron 1.8 GHz seems to be at the level of a 2.7-2.8 GHz P4, but it wouldn't surprise me if the Athlon 64 1.8 GHz performs better than the Opteron 1.8 GHz we tested today. The reasoning is that the Athlon 64 will not have the ECC performance penalty and will most likely have access to DDR400. The lower latency of DDR400 compared to DDR333 ECC is much more important than the small bandwidth advantage the Opteron might have. Lower latency will help with each L2-cache miss, more bandwidth will only help if there are so many L2-cache misses that bandwidth becomes a bottleneck. In other words, lower latency (DDR400, Athlon 64) will always improve performance, more bandwidth (Opteron) will only improve performance, if you are running out of it. With a 1 MB L2-cache, that is less likely. ''
