Itt a szerver-teszt utolsó oldaláról egy táblázat (azt mutatja meg, mekkora órajelű xeonnal van pariban)

General applications Opteron 2350 (2GHz) equates to Xeon clock speed of:
WinRAR 3.62 2.7 GHz
Fritz Chess engine 1.8 GHz
HPC applications
Intel optimized Linpack 1.9 GHz
3D Applications
3DS Max 9 2 GHz
zVisuel 3D Kribi Engine 2.33 - 2.4 GHz
zVisuel 3D Kribi Engine (AA) 2.4 GHz
Server applications
Specjbb 2.4 GHz
MySQL 2.33 GHz
Nem lenne ez rossz,
ha nem 2,0 ghz lenne a maximum, év végére esetleg 2,5 ghz, csakhogy novemberben már jönnek az új xeonok, kicsit továbbcsiszolt architekturával (pár plusz-százalékot ez is hoz) 3,16 ghz nyitó maximális órajelen.
És ami a lényeg: ezzel az AMD most architekturálisan
sok időre ellőtte a puskaporát, innentől abban lehet reménykedni, hogy minél hamarabb és minél magasabbra tudják majd emelni az órajelet. Tegyük fel, hogy év végére, jövő év elejére (bár a 08H2 2,6 ghz-nél többet még ők maguk sem vállatak!) órajelben feljönnek annyira, hogy azzal már teljesítményben pariban lesznek a Core-ral - de jövőre már jön Nehalem...
A gyárthatósági/gazdaságossági kérdésekről nem is beszélve.
Na mind1, ez még messze van, becopyzom a két anandtech-cikk konklúzióját is:

Final Words
We can't draw too many sweeping conclusions based on the data here today, but here's what we do know:
- Gaming performance is much improved with Barcelona over K8, this is most likely a result of the improvements to the SSE engine and the wider front end of the core.
- Encoding performance is improved (again SSE128 rearing its head), but 3dsmax saw an unexpectedly large performance improvement.
- With a 10 - 15% increase in performance on average, Phenom should be more competitive than K8 was on the desktop (as expected).
Here's where things get complicated; we knew Phenom/Barcelona would be faster clock for clock, it was only a matter of how big of an improvement we'd get. If we are to believe that 15% is the best we'll get on average, taking into account that Penryn is around 5% faster than Conroe, the updated architecture from AMD alone isn't enough to really compete with Intel. In other words, price matters.
We saw how competitive AMD became after the first round of price cuts this year, but after the second set Intel went back to dominating. The trouble for AMD this time around is that Phenom is a much larger chip than the outgoing Athlon 64 X2, whereas Intel's Penryn family will actually be smaller than Conroe. AMD is already losing a considerable amount of money each quarter, so fabbing a larger chip at the same price as current CPUs will only make the situation worse. However, Intel can afford to continue to keep its processors as aggressively priced, especially moving to 45nm.
To put it plainly: Phenom/Barcelona make this price war more difficult on AMD, while Penryn makes it easier on Intel. What's the end game? Is there a solution? We're not sure, all we know today is a starting point for Phenom expectations.

Conclusion
It's close to a nightmare to try to review a server CPU in a few days, but we hope we have at least provided you with an idea what AMD's newest quad-core is capable of. We'll summarize our preliminary results with this small table.
The Opteron 2350 (2 GHz) vs. Xeon "Clovertown"
General applications Opteron 2350 (2GHz) equates to Xeon clock speed of:
WinRAR 3.62 2.7 GHz
Fritz Chess engine 1.8 GHz
HPC applications
Intel optimized Linpack 1.9 GHz
3D Applications
3DS Max 9 2 GHz
zVisuel 3D Kribi Engine 2.33 - 2.4 GHz
zVisuel 3D Kribi Engine (AA) 2.4 GHz
Server applications
Specjbb 2.4 GHz
MySQL 2.33 GHz
Considering that AMD prices this Opteron 2350 under the Xeon 5345, AMD has an attractive price/performance offering for most applications. The only exception is a chess engine and highly optimized Intel binaries. Although our testing is not finished yet, there is very little doubt that AMD's newest chip is very energy efficient. Add to that the fact that the AMD platform is not burdened with the extra power consumption of FB-DIMMs, and it is clear that the third generation of Opterons will lead in the performance/watt area for a few months. When you are looking for the highest performance however, Intel has still a solid advantage with it's 3 GHz Xeon x5365
The future looks very interesting with the 45nm Xeon Harpertown and a 2.5GHz AMD quad-core in the next quarter. AMD hasn't clearly hit a homerun this time, but at least they're playing in the same ballpark.
Again, if you're curious about how quad-core Opteron functions in more of a desktop capacity - as a preview of things to come with the launch of Phenom - don't miss our AMD Phenom Preview article. We tossed in a GeForce 8800 GTX and ran some gaming and general computing performance numbers. It's still a socket 1207 server motherboard, but we limited the comparison to Santa Rosa versus Barcelona Opteron performance in order to focus on the CPU and not on potential platform differences.
