Changing the Game: Overclocking

Although AMD is unusually competitive in the mainstream segment, it's a whole new ballgame once you take overclocking into account. The type of overclocking we're talking about here is very mild, using nothing more than stock coolers and not pushing voltages too high. The goal is getting more bang for your buck without sacrificing stability or increasing the price; we're trying to see how much you can really get from these ultra-affordable CPUs. Our table of overclocks is listed below:

Overclocking Results (Stock HSF)
CPU Stock Clock Overclock Percentage
AMD Athlon 64 X2 5000+ 2.6GHz 2.86GHz 10%
AMD Athlon X2 BE-2350 2.1GHz 2.41GHz 14.70%
Intel Core 2 Duo E4500 2.2GHz 3.12GHz 41.80%
Intel Pentium E2160 1.8GHz 3.02GHz 67.70%
Intel Pentium E2140 1.6GHz 2.69GHz 68.10%

You can see that the AMD chips overclock a bit but nowhere near as well as the Intel CPUs. Intel has a slightly deeper pipeline which allows it to reach higher clock speeds somewhat easier; the rest of the headroom may simply be due to advantages in Intel's 65nm process over AMD's. Remember that Intel has been manufacturing 65nm CPUs for much longer than AMD, thus having had more time to fine tune the process to maximize clock speed and minimize thermals.

We ran a single benchmark to showcase the improvement you'd get from these simple overclocks (at least in CPU limited situations). The benchmark we chose was our WME9 test, which is fairly close between AMD and Intel to begin with, giving both a fair starting point prior to overclocking:

Overclocked Performance - Windows Media Encoder 9

Here's the problem: the fastest AMD CPU we tested gets around 45 fps in our WME test, while the cheapest Intel CPU when overclocked gets 51 fps. There's no simpler way of putting it: if you take overclocking into account, there's just no way to even consider the AMD CPUs. With the Pentium E2140 and 2160 boasting 65%+ overclocks, their performance reaches levels greater than the Athlon 64 X2 5000+ (and some of the faster Athlon X2 CPUs as well).

    Wow, very mature response.

    BTW, I'm an Intel user with a pair of Q6600 rigs as well as an older 939 rig.

    I stand by my comments, Anand got the pricing and hardware wrong, period.

    are there any good intel matx mobos with hdmi (or integrated gfx?)

    that's the only reason why i would consider going with AMD, because cpu performance doesn't make that much of a big deal to me, but having onboard hdmi would (and a better integrated chipset overall)

    Can we please get a review of the 14.31.1 XP driver for the GMA X3000 that enables hardware DX9.0c SM3.0 acceleration? I know you've switched over to Vista, but the 15.6 driver release notes don't mention that they added hardware acceleration so it looks like only the 14.31 and the newer 14.31.1 XP drivers have it. I would love to see a comparison between the GMA X3000, Xpress X1250, Geforce 7150, and a discrete X1300HM and 8500GT.

    You're probably saving the new drivers for an IGP review when the G35 GMA X3500 comes out (October 21?), but it would be nice to have numbers for the GMA X3000 too for comparison.

    Would be wonderful to have a MB roundup to go along with a processor roundup.

    Please?

    We ran into one problem where our GeForce 6150 motherboard wouldn't POST without a PCI Express graphics card installed unless we switched power supplies. Memory selection is also critical for ensuring proper operation, and these motherboards are very picky about what they will and won't work with. We'd strongly suggest consulting approved memory devices/vendors if you do end up going with any GeForce 6xxx based motherboards, or better yet, opt for something based on the AMD 690 or NVIDIA GeForce 7xxx chipsets.


    I feel that the mothernoards you used for your tests were not up to the task. Earlier this year, I went out on a limb(for my personal standards) in buying a very in-expencive motherboard in hopes of saving $20-$30 usd on my system costs. While I did not experience any of the issues you mention having with the Geforce 6000 chipset that you mentioned here, I found this board to be completely un-exceptable stability wise. Every 3-5 days, the system would lock up, or BSoD(and sometimes much sooner). This system board did not have any memory voltage adjustment settings what-so-ever, and this was probably a big part as why the motherboard would not run smoothly(the board defaulted my memory lower than it should have been). Overclocking this system board also proved to be fruitless, even though there were enough options(short of the memory voltage settings) to do so. This motherboard was also plauged by other problems, one of which where talking to the 'tech' staff at the manufactuer proved that I was obviously more knowledgable concerning their own hardware, and every other set of words out of this 'techs' mouth seemed to be 'This is a budget motherboard'. This is the responce I got even when asking for an updated BIOS link, and to this day, the BIOS for that board has never been updated.

    On the flip side, I purchased a similar board from a company that I trust, and have been dealing with for many years. This board was based on the 6150 chipset, has voltage settings for memory, and will easily overclock my AM2 1210 opteron to 3.0 Ghz(base frequency is 1.8Ghz). At current, the BIOS for this board has been revised 3-4 times, and while the motherboard has been phased out for a few months now, I suspect that the BIOS revisions will keep on comming based on past experiences with this company. This board has been very stable, with only a handful of BSoDs because of overclocking too high on the stock cooler, or a few other software related glitches. All while running WinXP Pro 32BIT with the /PAE boot option enabled. Also, since this motherboard OEM has a top notch Forum, and I have found this board to be virtualy trouble free(but not perfect), I have had no reason to even bother their tech representatives.

    These two different motherboards both used the same exact hardware on them, and the second one will work perfectly fine with Windows 2003, where as the first will not(no networking drivers).

    Leaving the two company names out of it, the moral of the story is; I had hoped to save myself $20-$30 usd, and it ended up costing me another $75 usd in the long run.

    Now naming names, the first board was an Asrock AM2NF-4G-SATA2, and the second board was an ABIT NF-M2 nView. Since I have named names yet again, I suspect a few 'Fan-boi' comments, but this is not about Fan-boi-ism; this is about an experience out of many similar in dealing with different companies over the past 13 years when purchasing parts for systems. Top Tier manufactuers are top tier for a reason . . . and trust me, I would rather pay less for another brand, for the same performance/stability, but it has been this users experiences(many times . . .) that I will be let down, and end up paying more in the long run to correct issues for sub standard parts/service.

    I have sold many GeForce6150 based computers to people without a problem at all. I have not tried to overclock them, but from what I understand I hear that they perform better than the 70xx series of integrated GPU's (I could be remembering wrong). I have had some sweet Winfast Foxconn boards with Nvidia 6150 chipsets, but also that new AMD chipset is pretty good.

    We needed new workstations earlier this year for a couple of students, so I built 2 computers using really cheap components. Used ECS motherboards (nVidia 6100 chipset) with some cheap X2 processors and a GB of Corsair ValuRam, powered by a power supply included in a cheap Rosewill case. No overclocking (obviously) but everything has been stable so far.

    I have built quite a few systems for customers using ECS motherboards. Have also replaced a few motherboard from eMachines, and whatnot with ECS motherboards. They all seem to work fine, as I have had zero complaints so far.

    In my own personal machines however, I may require extra features that the average user may not, and my most recent personal purchase has exactly what I want, for a fair price, and stability second to none.

    Having said that, we here also avoid Asus motherboards like the plauge, as we have had bad experiences with their boards, with the most 4 recent boards made by them showing up DOA here in our shop. Obviously, I do realize since Asus seems to be a trend among the younger users I've seen post around, that I do not think they do not work all the time; this is just our experiences here.

    I really do not respect DFI, BIOSTAR, like other brands such as ABIT, Gigabyte, and MSI(for Intel based systems) though. But if a customer wants a 'cheap' PC, thats what they get . . . and we usually recommend Dell in this case anyhow.

    little picky on nvidia's drivers

    nvida chip set drivers are updated every year (thay never seem to bother to update them) so there chipset drivers will not allways have the Nvidia display drivers and even if it did the first thing i do any way is get the new video drivers as well and install them after chpset drivers no problem

    Just wondering about this part of the article:

    "We'd take the slowest Pentium Dual Core over the fastest available Pentium D, so stay away from the last remnants of the NetBurst architecture if you know what's best for you."

    I bought a Pentium D 805 Smithfield 2.66GHz LGA 775 Processor a while ago as a stopgap for my new rig. Basically it was so I could use the system which had a 775 and wouldn't take my old P4, looking to upgrade to a Core 2 at the earliest opportunity. I found on the internet some information however that the Pentium D 805 was a diamond in the rough and could be easily overclocked to rival performance with some of Intel's extreme chips. Sure enough I got it to goto 3.2GHz without even changing anything but the FSB. Same cooling solution, same everything and the system is rock solid and pretty darn fast. Thus I decided to just stick with the Pentium D. Was I wrong to stay with it? Is going to the slowest Core 2 better than the setup I have now? Not trying to get in an argument, I'm honestly curious if I made a misjudgement and what the reasons for the slowest Core 2 being better than a Pentium D @ 3.2GHz (with supposed potential up to 3.6GHz or higher) are.
