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).

    I didn't mean to offend you, because i can imagine how much time it takes to test hardware properly. And i personally think that OLTP/OLAP testing is very innovative and needed. Because otherwise people would have no idea what to buy for servers. You cannot let you server purchase be influenced with meaningless (for servers) simple benchmarks like 3D 2006/Vantage/FPS test etc.
    You guys always are doing a great a job at testing any piece of hardware, but it is just feeling to much biased towards Intel. For example, at the last page of this review you get a link to Intel resource Center (in the same place as the next button). If you have things like that, you are not (trying to be) objective IMO.

    Thank you for clarifying in a very constructive way.

    "the last page of this review you get a link to Intel resource Center"

    I can't say I am happy with that link as it creates the wrong impression. But the deal is: editors don't involve in ad management, ad sales people don't get involved when it comes to content.

    So all I can say is to judge our content, not our ads. And like I said, it didn't stop us from claiming that Shanghai was by far the best server CPU a few months ago. And that conclusion was not on many sites.

    Thanks for clarrifying this matter.

    But ad sales people should know this creates the wrong impression. A review site (for me at least) is all about objectivity and credibility. When you place a link to Intel's Resource Center at the end of every review, it feels weird. People on forums already call Anandtech, Inteltech. And i don't think this is what you guys want.

    I always liked Anandtech since when I was a kid, and I still do. You guys always have one of the most in-depth reviews (especially on the very technical side) and I like that. But you guys are gaining some very negative publicity on the net.

    AMDZone is the biggest joke on the internet. I just went there to see how the zealots like abinstein are still doing their damage control; just like before he went on rambling how the Penryn is still weak against Shanghai, and the old and tired excuses like how if people all bought AMD they can drop in upgrades etc etc. ZootyGray...he's the biggest joke on AMDZone. None of them had the mental capacity to accept AMD has been DEFEATED, which is disappointing but funny to say the least Reply

    It's not just AMDZone, you are just the opposite. Its like in Woodcrest and conroe times, it's not because the high-end cpu is the best of all that the rest of the available cpu's in the line is by default better. It's all about price performance ratio. Like many who were buying the low-end and think they had bought the better system, well wrong bet.

    As mentioned before, why not test the mid range that is where the sales will be. Time to test 5520-5530 against 2380-82 after all those have the same price.

    Your argument is valid, however, it just so happens that for low end 1S systems the Penryns are doing just fine against the Shanghais, for higher end 2S systems they used to be limited by memory bandwidth and AMD pulls ahead. No more is this the case, Intel now beats AMD in their own territory. Reply

    You probably also can't afford to buy a computer, so I doubt that Intel will be too concerned with your AMDZone insanity. LOL!!!! Reply

    Those grapes you are chewing on sure sound sour to me. Try listening to a few tracks by The Fun Loving Criminals to help take away the bad taste. Reply

    There's more to HPC applications than you indicate: environmental modeling apps, particularly, tend to be dominated by memory access patterns rather than by I/O or pure computation. Give me a ring if you'd like some help with that -- I'm local for you, in fact... Reply
