TrueCrypt 7.1 Benchmark
TrueCrypt is a software application used for on-the-fly encryption (OTFE). It is free, open source and offers full AES-NI support. The application also features a built-in encryption benchmark that we can use to measure CPU performance. First we test with the AES algorithm (256-bit key, symmetric).
Core for Core, clock for clock, the Xeon E5 - which also supports AES-NI - is about 30% faster than the best Opteron (Xeon E5-2660 vs Opteron 6276). At a similar pricepoint (Opteron 6276 vs Xeon E5-2660 6C) however, the Opteron and Xeon E5 perform more or less the same, with a small advantage for the latter.
We also test with the heaviest combination of the cascaded algorithms available: Serpent-Twofish-AES.
The combination benchmark is limited by the slowest algorithms: Twofish and Serpent. This one of the few benchmarks where the Opteron 6276 is able to keep up with the Xeon E5.
It is important to realize that these benchmarks are not real-world but rather are synthetic. It would be better to test a website that does some encrypting in the background or a fileserver with encrypted partitions. In that case the encryption software is only a small part of the total code being run. A large performance (dis)advantage might translate into a much smaller performance (dis)advantage in that real-world situation. For example, eight times faster encryption resulted in a website with 23% higher throughput and a 40% faster file encryption (see here).
7-Zip 9.2
7-zip is a file archiver with a high compression ratio. 7-Zip is open source software, with most of the source code available under the GNU LGPL license
Compression is more CPU intensive than decompression, meanwhile the latter depends a little more on memory bandwidth. When it comes to load/stores and memory bandwidth, the Xeon E5-2660 is about 13% faster than AMD's flagship. Compression is for a part determined by the quality of the branch predictor. The new and improved Sandy Bridge branch predictor is one of the reasons why a 2.2 GHz 6-core 2660 is able to keep up with a 2.93 GHz (!) Xeon 5670, which is also a six-core processor. The Opterons get blown away in the compression benchmark: each core of Xeon E5 is about twice as efficient in this task. The overall winner is thus once again the Xeon E5.

You've put that Interlagos has 4x2MB L2, but that would only be true for Valencia; Interlagos is 8x2MB.aranyagag - Thursday, March 8, 2012 - link
you forgot the E5-2687W with a 150w tdp and higher speedscolonelclaw - Friday, March 9, 2012 - link
Hi There,Thanks for an excellent article. With regards to the rendering benchmarks, would you consider using VRay as a rendering engine? It's fast becoming industry standard, is compatible with all the big hitters (Max, Maya, Softimage etc), is cross platform, and I believe, is incredibly well coded to scale with cores.
It's also incredibly popular, not something you could say about iRay right now.

Would be nice if some game benchmark was included as well.colonelclaw - Wednesday, March 14, 2012 - link
Bloody hell those chips look good, and don't Intel know it; those prices make me wince.Having waited what seems like forever, I was thrilled to see the Xeon E5s finally available, right up until I did some quick maths and figured out that for my business to buy a new 2U Twin squared rendernode with 16/32 cores per node will cost us around £10,000. Still the thing is, now that those chips are available, next time we buy kit we can't afford not to choose them.

Great article... but can it run crysis?Seriously, what will happen if you plug in some high end graphics card in that machine, how will that compare from a gaming perspeective to say an LGA2011 cpu?
;-)

From the 'article' .....'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'
Well, if that's the case, why exactly would AMD be scoring so many design wins with Interlagos. Including this one ...

U think those guys at Cray were going for low performance ? In fact, seems like AMD has being rather cleaning up in the HPC market since the arrival of Interlagos. And the markets have picked up on it, AMD stock is thru the roof since the start of the year. Or just see how many Intel processors occupy the the top 10 supercomputers on the planet. Nuff said ...

Hi, abit blur here and would like to know if there's anyone who could enlighten abit.I'm looking to purchase a new server to work with an SQL 2012 4 core, the initial ppreference was for an E5620 which is now an outdated model but I can't go for higher E5-xxx models as all are 6 core and will affect the 4 core SQL licensing. I'm not running a huge databse but would like to know if there are any serious performance difference between the two processor. Appreciate it.

Les deux platines ci-dessus commençons par lance Gobelins ou la bombe tour/Canon au début de la bataille lorsque la barre de l'élixir obtient autour de 10. Je vais tout d'abord si l'ennemi a au compteur et ils ont habitude de laisser tomber tout d'abord une grosse carte ou utilisez les flèches. Puis jouer à votre avantage avec le coût de l'élixir, troupes pour la défense et une attaque forte. Déposer le Canon ou la tour au milieu de rerouter les agresseurs et pour la défense.<a href="http://clashroyalhack.fr/">CR hack</a>

Le pont sur la gauche est une mise en page « plus grand risque de mieux récompenser », tandis que celui de droite est un jeu plus lent que prendra de temps et patience pour gagner. Tous deux sont extrêmement compétents et me laisser pousser à Arena 7.http://clashroyalhack.fr/
