Conclusions
Our conclusion about the Xeon E5-2690 2.9 GHz is short and simple: it is the fastest server CPU you can get in a reasonably priced server and it blows the competition and the previous Xeon generation away. If performance is your first and foremost priority, this is the CPU to get. It consumes a lot of power if you push it to its limits, but make no mistake: this beast sips little energy when running at low and medium loads. The price tag is the only real disadvantage. In many cases this pricetag will be dwarfed by other IT costs. It is simply a top notch processor, no doubt about it.
For those that prioritize performance/watt or performance/dollar, we've summarized our findings in a comparison table. We made 3 columns for easy comparison:
- In the first column, we compare Intel's newest generation with the previous one. We compare the CPUs with midrange TDP (95W).
- In the second column, we compare Intel's and AMD's midrange offerings.
- In the third column we compare CPUs with a similar pricepoint as we believe that a six-core E5-2660 will be very close to the performance of 2.3 GHz Xeon E5-2630.
We also group our benchmarks in different software groups and indicate the importance of this software group in the server market (we motivated this here).

It is pretty amazing that with the exception of two rendering applications with relatively mediocre scaling, the new Xeon is able to outperform the previous Xeons by a large margin (from 30% up to 60%) in a wide range of applications. All that performance comes with lower energy consumption and a very fast I/O interface. Whether you want high performance per dollar or performance per watt, the Xeon E5-2660 is simply a home run. End of story.
For those who are more price sensitive, the Xeon E5-2630 costs less than the Opteron 6276 and performs (very likely) better in every real world situation we could test.
And what about the Opteron? Unless the actual Xeon-E5 servers are much more expensive than expected, it looks like it will be hard to recommend the current Opteron 6200. However if Xeon E5 servers end up being quite a bit more expensive than similar Xeon 5600 servers, the Opteron 6200 might still have a chance as a low end virtualization server. After all, quite a few virtualization servers are bottlenecked by memory capacity and not by raw processing power. The Opteron can then leverage the fact that it can offer the same memory capacity at a lower price point.
The Opteron might also have a role in the low end, price sensitive HPC market, where it still performs very well. It won't have much of chance in the high end clustered one as Intel has the faster and more power efficient PCIe interface.
Ultimately, our hope for stiffer competion lies with the newest Opteron "Abu Dhabi" which is based upon the "Piledriver" core. The new Opteron was after all made to operate at 3 GHz and higher clockspeeds as opposed to the meager 2.3/2.6 GHz we have seen so far. Apparantely AMD will not only be able to boost IPC a bit (by 10% or more) but they may also significantly boost the clockspeed as we have learned from this ISSC paper: "a AMD’s 4+ GHz x86-64 core code-named “Piledriver” employs resonant clocking to reduce clock distribution power up to 24% while maintaining a low clock-skew target."
This should allow AMD to get higher clockspeeds within the same power envelope. Until then, it is the Xeon E5-2600 that rules the server world.

Thanks for running those.Are those results with HTT or without?
If you can write a little more about the run settings that you used (with/without HTT, number of processes), that would be great.
Very interesting results thought.
It would have been interesting to see what the power consumption and total energy consumption numbers would be for these runs (to see if having the faster processor would really be that beneficial).
Thanks!

I should work with you more to get you running some Fluent benchmarks as well.But, yes, HPC simulations DO take a VERY long time. And we beat the crap out of our systems on a regular basis.

This is the most interesting part to me, as someone interested in high network I/O. With the packets going directly into cache, as long as they get processed before they get pushed out by subsequent packets, the packet processing code doesn't have to stall waiting for the packet to be pulled from RAM into cache. Potentially, the packet never needs to be written to RAM at all, avoiding using that memory capacity. In the other direction, web servers and the like can produce their output without ever putting the results into RAM.meloz - Tuesday, March 6, 2012 - link
I wonder if this Data Direct I/O Technology has any relevance to audio engineering? I know that latency is a big deal for those guys. In past I have read some discussion on latency at gearslutz, but the exact science is beyond me.Perhaps future versions of protools and other professional DAWs will make use of Data Direct I/O Technology.

wow. 20MB of on-die cache. thats ridiculous.PwnBroker2 - Tuesday, March 6, 2012 - link
dont know about the others but not ATT. still using AMD even on the new workstation upgrades but then again IBM does our IT support, so who knows for the future.the new xeon's processors are beasts anyways, just wondering what the server price point will be.

"AMD's engineers probably the dumbest engineers in the world because any data in AMD processor is not processed but only transferred to the chipset."...What?

Like the Ivy bridge comments, just for future readers note that this was a reply to a deleted troll and no longer applies.IntelUser2000 - Tuesday, March 6, 2012 - link
Johan, you got the percentage numbers for LS-Dyna wrong.You said for the first one: the Xeon E5-2660 offers 20% better performance, the 2690 is 31% faster. It is interesting to note that LS-Dyna does not scale well with clockspeed: the 32% higher clockspeed of the Xeon E5-2690 results in only a 14% speed increase.
E5-2690 vs Opteron 6276: +46%(621/426)
E5-2660 vs Opteron 6276: +26%(621/492)
E5-2690 vs E5-2660: +15%(492/426)
In the conclusion you said the E5 2660 is "56% faster than X5650, 21% faster than 6276, and 6C is 8% faster than 6276"
Actually...
LS Dyna Neon-
E5-2660 vs X5650: +77%(872/492)
E5-2660 vs 6276: +26%(621/492)
E5-2660 6C vs 6276: +9%(621/570)
LS Dyna TVC-
E5-2660 vs X5650: +78%(10833/6072)
E5-2660 vs 6276: +35%(8181/6072)
E5-2660 6C vs 6276: +13%(8181/7228)
It's funny how you got the % numbers for your conclusions. It's merely the ratio of lower number vs higher number multiplied by 100.
