You don't buy a server CPU of course; in most cases you buy a complete server. Still, the impact of the top of the line server CPUs on the total server price is still relatively high, so it does not hurt to compare on price too.

Server CPU Pricing
Intel CPU Price AMD CPU Price
Xeon X7460 2.66 GHz (6 core, 16 MB) $2729    
Xeon E7450 2.4 GHz (6 Core, 12 MB) $2301 Opteron 8384 2.7 GHz $2149
Xeon E7440 2.4 GHz (12 MB) $1980 Opteron 8382 2.6 GHz $1865
Xeon E7430 2.13 GHz (12 MB) $1391 Opteron 8380 2.5 GHz $1514
Xeon E7420 2.13 GHz (8 MB) $1177 Opteron 8378 2.4 GHz $1165
    Opteron 8350 2.0GHz $873
Xeon L7455 2.13 GHz (6 core, 12 MB) $2729    
Xeon L7445 2.13 GHz (12 MB) $1980 Opteron 8347 HE 1.9 GHz $873

The Opteron 8384 is clearly aimed at six-core Xeon 7450 2.4GHz.

Server CPU Pricing
Intel CPU Price AMD CPU Price
Xeon X5470 3.33 GHz (120W) $1386    
    Opteron 2384 2.7 GHz (75W) $989
Xeon E5450 3.0 GHz (80W) $915 Opteron 2382 2.6 GHz (75W) $873
Xeon E5440 2.83 GHz (80W) $690 Opteron 2380 2.5 GHz (75W) $698
Xeon E5430 2.66 GHz (80W) $455 Opteron 2380 2.4 GHz (75W) $523
Xeon X5420 2.5 GHz (80W) $316 Opteron 2378 2.3 GHz (75W) $377
Xeon X5410 2.33 GHz (80W) $256    
Xeon L5430 2.66 GHz (50W) $562 Opteron 8350 HE 2 GHz (55W) $316

Meanwhile, the Opteron 2384 targets the 3GHz Xeon E5450.

    I'm surprised by your comments. You claim that VMmark is a CPU/memory-centric benchmark. If I look at the raw data in the VMmark disclosure for Dell's R905 score of 20.35 @ 14 tiles, I see that the benchmark is driving 250-300 MB/s of disk IO across several HBAs and storage LUNs. This characteristic scales with the various systems mentioned in the article.

    As a designer of VMmark, I happen to know that both storage bandwidth (for the fileserver) and latency (for mail and database)are critical to acheiving good VMmark scores. Furthermore, the webserver drives substantial network IO. The only purely CPU-centric component to VMmark is the javaserver. Overall, the benchmark does exercise the entire virtualization solution - hypervisor, CPU, memory, disk, and network.

    While SAS and Infiniband share some connectors and obtain similar data rates, they are incompatible technologies with two different purposes. Infiniband can be used for disk shelf connections, but it is less common and definitely not the case here. You should not call the connection between the Adaptec 5805 controller and the disk shelf an "Infiniband connection", even if it is using Infiniband connectors and cables, it is simply an SAS connection.

    Well, the physical layer is Infiniband, the used protocol is SCSI. I can understand calling it an "infiniband connection" maybe confusing, but the cable is an infiniband cable.

    Anand, I think the above poster is right. The Adaptec RAID 5805 uses SFF-8087 connectors but the protocol is SSP (Serial SCSI Protocol). Infiniband is a physical layer protocol that shares the same connector as SAS but they are not the same. Nothing in the Adaptec RAID 5805 spec mentions Infiniband as a supported protocol.">

    I'm not sure you can run your same ol benchmark for rendering, and I'd really like more insight into what you guys are rendering and if it's indeed using all 16/24(six core 4 point system)/32(hyperthreading) cores on the system.

    What renderer, what scene, details details...

    These chips get gobbled up by render farms and this is indeed where they can really flex their muscles to the fullest.

    Just click on the link under "we have performed so many times before" :-)

    I read DailyTech and to keep up with the latest in IT. I appreciate the thought that has gone into putting together this article. I would like to see more articles like this one.

    The VMware results shocked me the most. I know AMD has been working hard on the virtualization sector and it looks like their work has paid off.
  • classy - Tuesday, December 23, 2008 - link

    With the rapid increase of virtualization, AMD is looking really strong. We have begun using 3.5 Vmware and are expanding the use of it. Virtualization is truly becoming a big thing in server choice.
