What Intel is Offering

So what are Intel newest offerings and how do they compare to AMD? First, since power consumption is more important in servers than in high-end desktops, Intel selects the 2.93GHz Nehalems with the lowest power consumption (less than or equal to 95W TDP) and sells them in the server market. The 95W-130W TDP parts are for the desktop market. There is a 3.2GHz Xeon W5580 at 130W, but it's only targeted at the workstation market.

Processor Speed and Cache Comparison
Xeon model Speed (GHz) Max. Turbo Max. Turbo
4 cores busy
L3 Cache (MB) TDP (W)
X5570 2.93 3.33GHz 3.2GHz 8MB 95
X5560 2.8 3.2GHz 3.066GHz 8MB 95
X5550 2.66 3.066GHz 2.93GHz 8MB 95
E5540 2.53 2.8GHz 2.66GHz 8MB 80
E5530 2.4 2.66GHz 2.53GHz 8MB 80
L5520 2.26 2.4GHz 2.33GHz 8MB 60
L5510 2.13 No turbo No Turbo 4MB 60
E5520 2.26 2.4GHz 2.33GHz 8MB 80
E5506 2.13 No turbo No Turbo 4MB 80
E5504 2 No turbo No Turbo 4MB 80
E5502 1.86 No turbo No Turbo 4MB 80

Notice that the fastest 95W parts are able to boost their frequency with two 133MHz increments even if all four cores are busy. In reality, we have noticed that with most business workloads a 2.93GHz Xeon X5570 is running at 3.066 most of the time and from time to time even at 3.2GHz, but relatively rarely at 2.93GHz. In other words, you get a bit more clock speed than advertised. In rendering we noticed that peaking at 3.2GHz was rather rare, so the workload really determines how high the CPU will clock.

 


1366 pads make contact with the new Xeon motherboards

 

The E5520 to E5540 Xeons boost their clock speed by only one increment if all cores are busy. The E550x versions are really the low end: they get no Hyper-Threading (SMT) nor are they able to boost their clock speed (Turbo mode).

    We've a customer who is interested in upgrading to Nehalem. He's running on Windows with Oracle database for SAP Enterprise Portals.

    Could you kindly let us know your recommendations please?

    The approximate concurrent users would be around 3000 Portal users.

    Keenly looking forward for your response and if you could state any instances of Nehalem installed in SAP environment for production usage, that would be a great deal of help.

    Regards,
    Chary

    Hello,

    I understand the PHP not-enough-threads explanation as to why Dual X5570 doesn't scale up.

    But, can anyone please explain why when you add another AMD Opteron 2384 the increase is from 42.9 to 63.9, while when you add another Xeon X5570 there isn't such an increase?

    Thank you for the article,

    Adun.

    Was it really too much effort to clean off the processor before posting a picture of it? Or were they trying to show that it was used, tested?

    Would you perhaps like us to draw a smiley face on it as well? ;-) Reply

    Well done on an excellent review using as many real-world tests as possible. The VMWare test is a real eye opener and shows how the 55xx can match double the number of CPUs from the last generation of Xeons *AND* crucially save $$$$ on licensing from Windows and MS SQL and other per-socket licensed software, plus the power saving which is again a financial saving if you hire rack space in a datacentre.

    I eagerly await your own in-house VM tests. Please consider also testing using Windows 2008 Hyper-V which I think doesn't have the 55xx optimisations that the latest release of VMWare has (and might not have until R2?).

    Thanks for the time you put in to running the endless tests. The results make a brilliant business case for anyone wanting to upgrade their servers. You must have had the chips a good week before Intel officially launched them. :-) I do feel sorry for AMD though. I'm sure they have plenty of motivation to come back with a vengeance like they did a few years ago.

    Thanks! Good to hear from another professional. I believe the current Hyper Beta R2 already has some form of support for EPT.

    Our virtualization testing is well under way. I'll give an update soon on our blog page.

    You mention octal servers from Sun and HP for VM's, but does anybody really use these systems for VM's? I can't imagine why anybody would, since you are paying a serious premium for 8 sockets vs. 2 x 4 socket servers, or even 4 x 2 socket servers. Then the redundancy options are much lower when running only a few 8 socket servers vs many 2 or 4 socket servers when utilizing v-motion, and the expansion options are obviously far less w/ NIC's and HBA's. From what I've seen, most 8 socket systems are for DB's. Reply

    What i mentioned after reading the review is there are very few benches on benchmarks a little bit favored by AMD.

    For example, only 1 3DSmax test (so unusefull) at least 2 are needed
    Only 1 virtualization benchmark, which is really a shame....
    Virtualization is becoming so important and you guys only throw in one test?

    Besides that, the review feels a bit biased towards intel, but i will check some other reviews of the xeon 5570

    Virtualization benchmark come from the official Vmmark scores.

    However there is something real strange going on in the results...

    HP HP ProLiant DL370 G6
    VMware ESX Build #148783 VMmark v1.1
    23.96@16tiles
    View Disclosure 2 sockets
    8 total cores
    16 total threads 03/30/09

    Dell Dell PowerEdge R710
    VMware ESX Build #150817 VMmark v1.1
    23.55@16tiles
    View Disclosure 2 sockets
    8 total cores
    16 total threads 03/30/09

    Inspur Inspur NF5280
    VMware ESX Build #148592 VMmark v1.1
    23.45@17tiles
    View Disclosure 2 sockets
    8 total cores
    16 total threads 03/30/09

    Intel Intel Supermicro 6026-NTR+
    VMware ESX v3.5.0 Update 4 VMmark v1.1
    14.22@10 tiles
    View Disclosure 2 sockets
    8 total cores
    16 total threads 03/30/09

    So lets see all the prebuilds of esx3.5 update 4 get a real high score of 16 tiles almost as much as a 4s shanghai while Vmware performance team themselves stated that we should never see the HT core as a real cpu in Vmware (even with the new code for HT) while yet the benchmark shows a high performance increase, no not like anandtech is stating that this is due to the more available memory and its bandwith, those Vmmarks are not memory starving. Now look at the official Intel benchmark with ESX update 4, it provides 10 tiles and a healthy increase, that from a technical point of view seems much more realistic. All other marketing stuff like switching time etc, all nice, but then again is within the same line of current shanghai.

    What kind of tests are you looking for? The techreport guys have a lot of HPC tests, we are focusing on the business apps.

    "very few benches on benchmarks a little bit favored by AMD."

    That is a really weird statement. First of all, what is a test favored by AMD?

    Secondly, this new kind of testing with OLTP/OLAP testing was introduced in the Shanghai review. And it really showed IMHO that there was a completely wrong perception about harpertown vs Shanghai. Because Shanghai won in the tests that mattered the most to the market. While many tests (inclusive those of Intels) were emphasizing purely CPU intensive stuff like Blackscholes, rendering and HPC tests. But that is a very small percentage of the market, and that created the impression that Intel was on average faster, but that was absolutely not the case.

    "Only 1 virtualization benchmark, which is really a shame..."

    Repeat that again in a few weeks :-). We have just succesfully concluded our testing on Nehalem.

    Personally I am a bit shocked about the "not enough tests" :-). Because any professional knows how hard these OLTP/OLAP tests are to set up and how much time they take. But they might not appeal to the enthousiast, I am not sure.
