CPU and Motherboard Alternatives

CPU: AMD Athlon XP 2500+ (retail)
Motherboard: ABIT NF7-S Rev.2 (nForce2 Ultra 400)
Price: CPU - $80 shipped (retail). Motherboard - $98 shipped



For a mere $26 more, you can pick up an Athlon XP 2500+ that runs at 1.83GHz on a 333MHz DDR FSB and comes with a 512K L2 cache. In contrast to the Athlon XP 2000+, the 2500+ runs roughly 167MHz faster, comes with double the L2 cache, and has a FSB that is 67MHz faster. All this adds up to noticeably better performance, though depending on what applications you run, you may not notice. Still, there's no denying that if you're willing to spend a little more, you will definitely be getting a better performing processor.

Other differences between the Athlon XP 2000+ and the 2500+ is the 2500+'s higher Vcore (1.65V instead of 1.60V) and larger die size. Another nice thing about this processor is that it's quite an excellent overclocking CPU, and has been for months now, even if they are shipping multiplier locked these days. On a side note, this is the retail version of the 2500+, so your HSF (heatsink and fan) cooling is included for $80 shipped.



Since we've adjusted our original format from runner-up picks to alternative picks, our alternative picks for this refresh are different; in this case, ABIT's NF7-S Rev.2 instead of their KV7. The NF7-S Rev.2 is a better budget board than the A7N8X-X due to its better feature set (SPDIF, MCP-T South Bridge for superior sound), but it lacks a price as competitive at $98 instead of $69 like with the A7N8X-X. $29 is quite a big difference, but if you don't need better sound and/or SPDIF, then you have absolutely no reason to pick this motherboard. Though, if you're an overclocker, you have every reason to look at this motherboard, but that's probably not the case if you're reading an entry level guide like this one.

    I've built a lot of Athlon machines, and so has my co-worker for here at work. I haven't heard of one person complaining about instability or processor failure in all of the time that I have been familiar with computer hardware that couldn't be blamed on software. It's almost amusing to see the reliability argument pulled in when people are trying to decide between AMD and Intel. Anyway, I wanted to say that I personally had two very bad experiences with 9200SE video cards. Perhaps it was just the brand (PowerColor) but the 2D IQ was horrible. Text was barely readable and icons on the desktop had blurred shadows (shadows that didn't belong there). I tried in a few systems, and on a few monitors, and always the same. A regular 9200 (tried both Sapphire and Transcend) did not share those IQ problems. So I always recommend spending the extra $3 for a 9200 and not getting the SE.

    Also, that Cooler Master is rated only up to 900MHz Athlons, based on some sites that sell it.

    "We suggest the Cooler Master DP5-5G11A, ... If you're looking for something more quiet, we suggest mounting a Panaflo L1A fan to reduce noise. "

    That sounds like a 120mm fan to go on a heatsink that takes 50mm fans? I'm I missing something?

    I'm looking for a inexpensive but quiet way to cool my Athlon 1.4G. My existing fan is too noisy.

    By realistic I mean testing configurations that are likely to be made with high visual settings, so like I mentioned earlier, testing budget CPU's like Athlon XP and Celeron with $400 GPU's does not make sense, just like adding $300 worth of fast RAM to them.

    For C & C generals, I would not recommend playing it with a budget system, but if you must, you should use equal visual settings when you compare performance. And in my experience, user guessed CPU limits usually vanish with a faster GPU.

    Also, I have seen too many Athlon systems that did not even manage to keep working for three years of normal use, so I say that it is better to play at 60 FPS with Celeron and be able to save your progress, then to have frequent AMD related crashes at a whopping 62 FPS.

    sry, for double post, but I had to mention this: I have never had any problems with any processors, so I cannot really vouch for either intel or AMD here. However, We have at least ....4 computers with Athlon XP processors in our house and I know of some other people elseware, and NONE have had problems with them.


    what did you mean by the comment: "
    But generally speaking, a Celeron with dual channel memory will perform close to Athlons rating system when used with realistic benchmarks and settings." Realistic?!? what do you mean?

    Like I mentioned earlier, please read the budget CPU shootout article. AMD will always have an advantage over Intel in these low end CPU's.

    "And most benchmarks favor one CPU or the other, making it possible to have a Celeron outperform an Athlon 64 clock for clock, but also to create the results you mentioned, depending on the benchmarks used."

    True, but out of a unch of benchmarks, celerons only did barely OK in media encoding and they got killed in everything else. This is not just a case of benchmarks that favor AMD, this is just a fact: celerons suck. I remeber this comment: "All celerons have to offer is a high clock speed".

    The fact that they are generally more expensive than AMD processors(that are much faster in performance) while this is a budget system is another interesting point.

    You are right that this would not be a real gaming system, but that using Evan's entry level system, you could make a system that could run many games well enough. Just for kicks, lets talk about C and C generals with celerons vs Athlon XP's.

    The celeron I had (2.2) would barely even run C and C. The 1800+ with the same vid card ran it much, much faster. I know I wasn;t GPU limited, so that is not a factor here. The celeron simply could not handle the amount of data it had to process fast enough.

    It is not the performance that makes Celerons stand out, but their reliablity when paired with Intel mainboards does.

    And most benchmarks favor one CPU or the other, making it possible to have a Celeron outperform an Athlon 64 clock for clock, but also to create the results you mentioned, depending on the benchmarks used.

    Just when you benchmark a $400 GPU with a $75 CPU for games and select settings like 640x480 with no AA and AF, big differences will arise. But those differences are meaningless because nobody would use that CPU with that GPU and nobody with a $400 GPU would ever play with these low settings.

    But generally speaking, a Celeron with dual channel memory will perform close to Athlons rating system when used with realistic benchmarks and settings.

    Not to mention that none of these budget systems will offer serious game performance, but are more likely to be used for home office, Internet and small server appliances, where reliability is much more important then performance.

    25, Apparently you never read the CPU budget shootout where only a celeron 2.6 could barely manage to outperform an athlon 1800+ in media encoding and the celerons got raped in everything else. Celerons suck, period. Although they are Intel's budget CPU's they are still priced higher than AMD's processors which can kick their asses badly, ESP. when it comes to games. I once figured that I would try a celeron.........a 2.2 celeron with a geforce4 (with 64 ddr) AGP was outperformed badly by an Athlon XP 1800+ with a geforce4 (once again 64 ddr memory) PCI card. Badly.

    For a budget system, I would go for reliability, as most people want a system that actually keeps on going.

    So I would suggest:

    CPU & Cooling Intel Celeron 2400 - $71
    Mainboard Intel D865GBF - $96
    Memory 2 x 128 MB Kingston PC2100 - $52
    Video Card Onboard - $0
    Monitor Samsung SyncMaster 763MB $146
    Computer Case Antec SLK1600 - $46
    Sound Card Onboard sound $0
    Speakers Creative Labs SBS270 2.0 $20
    Networking Onboard 10/100 Ethernet $0
    Hard Drive - Seagate 7200rpm 40gig- $59
    CD-RW Samsung CDR-W/DVD Combo Drive,- $47
    Bottom Line - $537

    I think the extra $33 are very well spend, as this memory comes with lifetime warranty and it is much faster because of the dual channel setup. And this mainboard offers a very nice upgrade path, supporting the fastest CPU's available.

    Not to mention this setup allows you to tell your friends your real CPU speed without being laughed at.
  • Evan Lieb - Friday, March 19, 2004 - link

    Yeah Trogdor and mostlyprudent, definitely a lot you can do with such a small budget these days, and with great upgradeability.

    Zebo,

    Yeah, if you compare the two on the same monitor you will probably find the nForce IGP to be inferior. Even though text isn't "blurry" (depending on what your standard is, I suppose), sharpness can varry quite a bit.
