Phenom II Performance

The addition of the 955BE and 945 to the top of the Phenom II line now provides uncompromised choices of Phenom II in the midrange. As mentioned in the launch review, Phenom II is now the top performer in the midrange, with Core i7 owning the high-end. Even overclocking is once again an area where AMD need apologize to no one. The latest Phenom II cores are incredible overclockers, yielding even better performance. With the 955BE performance fresh on our radar, it was impossible not to choose the 3.2GHz 955BE as the heart of the latest Phenom II performance PC.

For detailed information on the Phenom II, please read yesterday's Phenom II X4 955 review. The Phenom II 955 at 3.2GHz is the fastest of the currently shipping AMD Phenom II processors, and it is built on a new stepping Phenom II 45nm core. The Phenom II is very similar in L2/L3 cache configuration to the Intel Core i7. Performance is also the best among today's midrange processors, and the 955 is only outperformed by the high-end Intel Core i7 series. As the latest 45nm AMD processor the Phenom II 955 also overclocks very well, matching or exceeding the very best Intel Core 2 Quad performance.

We've paired the Phenom II 940 with the new Gigabyte GA-MA790XT-UD4P motherboard based on the 790X chipset. The 790X is very similar to the 790GX chipset except it does not provide on-board graphics. It also supports the newest AM3 Phenom II processors and DDR3-1066/1333/1600 memory. Gigabyte combines the 790X with the latest AMD SB750 south bridge. This combo provides one x16 slot running at x16, a second x16 slot running at x8, three PCIe x1 slots, and two PCI slots. There are eight 3Gb/s SATA ports, a parallel port, and support for SATA RAID 0/1/5/10, 2600MHz HyperTransport, and maximum memory of 16GB in four slots.

The motherboard rear panel provides eight USB 2.0 ports, two Firewire, PS/2 keyboard and mouse, both optical and coax SPDIF out, and six audio jacks for the I-channel on-board audio. In addition there are two USB headers for internal USB and one additional 1394a (Firewire) header. The Gigabyte 790X board provides plenty of expansion capabilities for a performance AMD system, as well as excellent overclocking capabilities for those who plan to overclock.

The 790X chipset provides a single PCIe X16 slot and a PCIe x8 slot. This is fine for a single card and many will be happy with CrossFire that works as two PCIe x8 slots on the 790GX/X motherboards. However, if you have to have the very best CrossFire performance possible you should look for a motherboard based on the 790FX chipset, which does provide true dual PCIe x16 performance. This may be important to some, which is why we point it out. Otherwise, there is little to complain about with the performance of this Gigabyte AM3 motherboard.

The Phenom II is not the hot CPU you find in the Core i7, but it still benefits from third party cooling - particularly if you plan to overclock with a CPU with OC capabilities like the 955BE. We paired the Phenom II 955BE with the same Xigmatek Dark Knight used in our value systems, which performed well in the lab. At $40 the Xigmatek is an excellent cooling value.

Since the Phenom II is dual-channel DDR3, the motherboard was populated with a 4GB kit of OCZ Intel Extreme Edition DDR3-1600. This memory is rated at 7-7-7 at DDR3-1600 and 9-9-9-at DDR3-1800.  It is even faster at DDR3-1333 or DDR3-1066.  Don't worry about the Intel designation as it will work fine with your new Phenom II 955BE.  If you plan to extensively overclock you might have more flexibility choosing an even faster memory like  DDR3-1800 or  DDR3-2000, but our overclocking tests showed the highest memory speeds were somewhat wasted on the Phenom II and fast memory timings improved performance more. This fast and flexible memory gives both very fast timings and headroom when it is needed.

For the performance system, we upgraded the video card to ATI's latest Radeon HD 4890. As we stated in our review, the 4890 is basically a tweaked and overclocked 4870. It improves performance over the 4870 1GB and competes well with the GTX 275. On a pure performance level the 4890 and GTX 275 trade blows at different resolutions. MSI's overclocked HD 4890 bumps the clock speed up a little higher (880MHz instead of 850MHz), and with the current mail-in rebate it's $20 less than the GTX 275, so it gets our recommendation for the AMD performance build. Need even more power? Feel free to add a second card and run CrossFire. That should be enough for just about any current game at 2560x1600 (and is typically overkill for a 1080p display).

The case for the Phenom II performance system is a well-regarded Lian Li black all aluminum case. This Lian Li case has a reputation for being exceptionally quiet with its four 80mm fans with a fan speed controller and the excellent heat dissipation you expect from an all aluminum case. What is unique is the $40 savings on this case through the month of April, which reduces the cost to $100. There is even a side window for those who like a view of their working system.

The power supply is the IN WIN Commander 750W modular with a 140mm double ball bearing cooling fan. This superb 80 plus certified power supply would be a bit rich for an upper midrange performance rig at a normal selling price of $140. However, there is currently a $50 rebate that reduces the net price to just $90. If this PSU interests you then grab it at this great price as we're sure the rebate will go away as more buyers discover this value.

Most of our editors consider the onboard audio of motherboards to be adequate for even gaming these days. That is why we have not chosen a sound card for the performance midrange system. If you want more than that offered by onboard surround sound, the ASUS Xonar DX 7.1 is one of the top-performing audio cards on the market today. It is a great upgrade to the onboard sound if you want better sound quality. Game compatibility is excellent, but most game creators assume everyone has a Creative Labs sound card. If your main reason for having a powerful computer is gaming, you may prefer the Creative 7.1 Sound Blaster X-Fi Titanium at the same price. In our opinion, the sound quality is batter on the ASUS or an HT sound card, but game compatibility will never be a question with a Creative Labs sound card. We also upgraded to the Logitech G51 speakers. The Logitech rebate has ended, so the price is now $135 or so. They are still a decent value at that price.

The LCD display resolution is still the 1920 horizontal of the 1080p value system, but the 26" displays run at a 16:10 aspect ratio and WUXGA (1920x1200). Regardless of the minor resolution differences, the size of the monitor is now 26", so everything on the screen is a little larger - great if your vision isn't the best. The ASUS VW266H 25.5" provides the preferred HDMI input, as well as DVI and an analog VGA port. Panel speed is rated at an incredible 2ms, but we have found most current LCD panels perform similarly and the speed rating does not really guarantee very much. The ASUS monitor provides a large sharp image, good colors, and fast panel speed at a very good price of $320 after rebate. It comes with DVI and VGA cables, but if you plan to connect with HDMI you will need to buy a separate HDMI cable. The ASUS is also available with a rotatable 2MB webcam attached for just $20 more.

The hard drive remains 1TB but we selected the Western Digital 7200RPM for the Phenom II performance system at $105. This was mainly a concession to those who bitterly complain whenever we choose the Seagate as our 1TB drive choice. The WD is an excellent 1TB drive and it has never had any issues with failure, where early Seagate 1TB drives were plagued with firmware issues. The Seagate drives with recent firmware have performed fine in our labs, but if you are a buyer who worries about that the WD is the better choice. Seagate still provides a 3-year warranty and our experience with filing for warranty service online with Seagate has been excellent. The choice is yours - the Seagate is $85 and the comparable WD is $105.

The remaining components are the same as our value systems. The optical drive is the LG BD-ROM. The Microsoft OEM keyboard and optical mouse provide input and Vista Home Premium OEM runs the system. For more information on these components, you can refer to the descriptions on earlier pages.

In response to those who have asked for SSD recommendations, it is possible to finally make SSD recommendations based on the months of research and testing performed on SSD drives at AnandTech. For more information on SSD test results please see our SSD Anthology and the SSD Update. In keeping with the midrange pricing, we have listed an SSD option of the 60GB OCZ Vertex for the Phenom II performance system, though you could use a larger Vertex SSD if it better meets your needs.

Phenom II Value Final Words

    I ordered the OCZ Platinum 4GB just in case - the last thing I want to deal with is memory that doesn't play nice with my heatsink when I'd rather just enjoy my new build.

    Here's what I purchased:

    AMD Phenom II X4 955 $245
    GIGABYTE GA-MA790XT-UD4P $125 after rebate
    -$20 New Egg combo(CPU/mobo)
    OCZ Platinum 2x2GB DDR3 1333 7-7-7-20 $59
    Western Digital Caviar Black 640MB $75
    XIGMATEK Dark Knight $39

    At the end of the day I'll pay $530 with shipping. I'll use my old case, graphics card, sound card, monitor, etc. Not bad for a top of the line AMD CPU, AM3 mobo with DDR3 memory. And since most of the time the computer is used for gaming, AMD Phenom is a no brainer for price/performance.

    Below is my current build so as you can see it has been a few years - looking forward to today's modern speed.

    Now if only Windows 7 was available today!

    Oops I didn't mention the board I was looking at, which is the Gigabyte 790XT, which is what was this site recommended. So if the CPU cooler is in the way of the memory perhaps anandtech needs a new recommended memory module (I'm assuming without looking it up that the Gigabyte 790XT prefers the memory in slots closest to the CPU).

    Two of the top three articles are pumping the Phenom IIs as if anyone with a BRAIN would buy one.

    Seriously? You are recommending the Phenom IIs with "In WIN" Power supplies and Seagate hard drives?

    Why not rename to

    For a value system, I don't see anything that will beat either the Xeon W3520(i7 920) for single socket system or Dual Xeon E5504s on Asus Z8NA-D6C. Ditch the seagate and get the Western Digital Caviar Black, and ditch the "inwin" for an antec or PC power and cooling 750W. Ditch the freaking Radeon for a Geforce GTX275.

    Question: How long have you been on Intel's payroll? Reply
  • Wesley Fink - Saturday, April 25, 2009 - link

    The two articles also clearly said you should buy an Intel Core i7 if you have $290 or more to spend on a CPU. If you want to spend less on a rig then the articles recommend you buy a Phenom II.

    We also chose the WD 1TB for the Performance rig with a discussion of the issues with the early Seagate and the advice to choose the WD at $105 or the Seagate at $85. As for the nVidia 275 it is $30 more than the 4890. We also like to use AMD GPUs with AMD chipsets and processors if it makes sense - all else being equal.

    Did anyone pay you to post your accusations here? We hear that one of your recommended brands has paid staff whose primary job is to make accusatory comments that question the integrity of websites that recommend anything other than their brand. Since you always have something accusatory and blatantly nasty to say about every review lately we have to wonder. Our integrity is beyond reproach - can you say the same?

    I guess since I am graced with having a MicroCenter close enough to make shopping there a viable option, I don't have to put up with the Newegg price gouge on Core i7 920 cpus and can buy them for $230, and even get the luxury of having a B&M store to do instant and easy returns for items, instead of the typical 2 week ship-return-reship boogie you have to play with Newegg.

    Given that a Core i7 930 is $230, which undercuts the Phenom II 955, I'd think that in this particular instance the Core i7 becomes the better value and buy.....esp. if buying either the Phenom II or Core i7 would require buying new mb and memory. I'd honestly rather invest the $$ in my wallet in an architecture that has a distinct performance advantage and a longer longevity outlook with the Socket 1366.
  • JarredWalton - Sunday, April 26, 2009 - link

    Best price I can find on a Core i7 920 is">$266 at eWiz, which is quite a bit more than $230. Not sure how MicroCenter is supposed to be so great... their online site doesn't even list Core i7 CPUs that I can see. Perhaps the pricing is for employees only? Reply

    Hey, I can guarantee you that intel doesn't pay me to spread fud. Their CPUs deserve to be praised for technical leadership. I know my comments are usually negative, but ask yourself this question: did you guys deserve it? Anandtech isn't the same when anandtech got started , everyone knows it. Pumping inferior technology makes you look stupid that is all. Anyone recommending AMD platform right now over the nehalems has to really look deep into their heart and see if their intentions are honorable. Europeans are overly AMD biased because of Dresden fab.

    Right now AMD's business practice is dishonorable at best. Look at the way they flush their broken CPUs down consumers' throats. No, the phenom 2 955 is not that impressive: their uncore imc clockspeed is still castrated compared to their opteron line, and Istanbul will only exacerbate the problem.

    Why don't you do some real reviews, like how much ass the xeon e5504 e5520 and l5520 kicks over anything amd has on a performance per watt per dollar metric? Even in the consumer space, phenom 955 just barely caught up with 95w q8200 and it is only 100 dollars at microcenter.

    So I go to this page">

    And I look at the graph. 3.2 Ghz Core i7 = 87 FPS. 3.2GHz Phenom II = 86.4

    So, tell me why I would spend a few hundred dollars more to get 0.6FPS increase? Oh, I know why, its because you are paid by Intel to recommend them, to cause trouble. But one problem though - since you post in such an offensive and obviously trolling manner, your posts generally do the opposite of what you intend. People look at them and think, "Man whatever that guy is recommending, I'm having NONE of it, look how angry he is"

    Besides, if Anandtech really were shills, who has more money - AMD or Intel? Who could afford to pay Anandtech to shill more?

    Yeah, if you gave me another $500 I'd consider a Core i7. Until you do that, I'll put my money where it makes sense - right now thats AMD, but if Intel drops prices on their C2Q's they would get my vote. I really dont care about brand names, I care about performance and price. That you get so offended at the idea of a Phenom 2 recommendation is laughable - Phenom 1 I agree was a piece of crap but Phenom 2 is leaps and bounds better.

    So crawl back under the bridge little troll.

    Quoting a GPU bound FPS benchmark to try to fudge CPU equivalence shows how stupid you really are. Of course the FPS would be close since you are using the same video card. This was my original complaint for the "phenom is a great gaming platform" bs.

    Please for your own benefit, stop calling me a troll, it makes you look stupid. But then again people already know that.

    Right now the enterprise line cpus from both intel and amd are better than their consumer counterparts. For the same price, you get a far better cpu. So get a Xeon or Opteron instead of Phenom junk. I am not joking. Xeon w3520 is d0 stepping and easily does 4.0ghz on air.
