Making Sense of CPU and GPU Model Numbers?

b4dc0d3r writes "How do you make sense of the various model numbers or naming schemes for CPUs, graphics cards, and the related chipsets? All I want is something that will run Oblivion and output full 1080 video to a TV. Last time I built my own computer I just went to Pricewatch, made a few easy choices, and everything came to my door. Do I really have to research the differences among Core i5, Core 2 Duo, Pentium 4, Pentium D, Sempron, Athlon, Phenom ...? And that's just the processor. Is there a reference somewhere? In short, how do you buy a computer these days?"

    Actually, if you want to run Oblivion with the "must-have" mods (Better Cities, OOO or whichever leveling mod you prefer, some better texture pack), you'll still need a relatively well configured system. The game might be 4 years old, but it can still be very demanding (and IMO still looks and plays great, once mod'ed correctly)

  6. Just buy a complete machine by mcvos · · Score: 4, Informative

    Just find a reputable computer seller and order a machine that fits your budget. It'll probably run whatever you need it to run. If Oblivion is the heaviest game you're going to run, you can be done for about $500 probably.

    If you don't want the same boring standard machine that everybody else has, then you'll have to do some research. I did that 2 years ago. My main resource was Silent PC Review because I was tired of my old jet-engine-soundalike. AnandTech is also a good source, as is Tweakers, if you happen to be Dutch. Lots of articles on those sites will refer to Tom's Hardware, which does benchmark graphs, but really, just get what everybody's recommending.

    Two years ago, I went with:

    • Intel Core 2 Duo E8400 (brand new at the time, very fast, very low power usage, therefore little heat) with a passive Scythe Ninja cooler,
    • ATI HD3850 (new, powerful, not overly expensive, good for all games expect Crysis, low power usage when not doing 3D stuff) from Peak (cheaper than other HD3850s because they had a badly fitted cooler which I was going to replace anyway) with passive Accelero S1 cooler (very effective passive cooler, and very cheap).
    • Seasonic S12II-380 power supply (SeaSonic has the quietest PSUs, and 380 W is more than enough for a modern PC that doesn't try to waste as much power as possible),
    • Antec Solo case (Antec makes the quietest cases, but stay away from their power supplies)
    • Some new Samsung harddisk that everybody else was using too.
    • Some Gigabyte motherboard with P35 chipset, which was what you needed two years ago

    All of this cost me about EUR 1000. Very happy with it. Dead quiet, too. Mind you, this is from 2 years ago. There's probably better, cheaper, quieter, faster stuff around now, but I'm not keeping up.

    As for the dual core/quad core stuff: how many heavy CPU-using applications will you be running at the same time? Will your heaviest applications be able to make efficient use of multiple cores? If you don't know, go with dual core. One for the main app, one for everything else. No need to have to extra cores that are only idling all the time.

  7. Hardware virtualization by thue · · Score: 5, Informative

    Make sure that the CPU you buy supports hardware virtualization, for running virtual machines. Every computer enthusiast should want to run virtual machines!

    I think all current AMD CPUs support hardware virtualization. But Intel in their infinite market segmentation wisdom has decided to randomly disable hardware virtualization on various CPUs in their lineup, so look before you buy. The funny thing is that very few computer salesmen know for which CPUs hardware virtualization is enabled, so the only result of Intel's market segmentation is confusion and dissatisfied customers.

    1. Re:Hardware virtualization by cbope · · Score: 5, Informative

      Actually, Intel has gone and done something even more stupid than that: They even disable the virtualization extensions within processors of the same model number! Within a model, there may be multiple sspec numbers. Some sspecs may support virtualization and some may not. I don't have a specific example at hand, but I have seen it when using the Intel sspec finder tool on their website.

      So you not only need to understand which models "may" support virtualization, you also have to qualify it with looking up the model's sspec. Utter stupidity on the part of Intel for that.

    Wow, what nonsense!
    I personally build almost all my family's and my company's PC's, from simple $300 desktops to $5000 servers and the only cases where I have bought pre-built (hence the "almost all") were towards the latter ($5k) category. I find it much more important to built a cheap pc yourself, because you control exactly where the limited budget goes and you end up with a much better pc for your intended use for the money.

    This. Also, during the 1990s computer performance increased dramatically, as in it went from 10MHz to 1000MHz. Since then things have sort of reached a level of "good enough". For instance, I kept my motherboard and processor the same from 2002-2007, simply because it was still able to run most current software just fine. The only things which really prompted an upgrade were Oblivion and a desire to play with a 64-bit OS.
    And as the parent says, that was a long enough wait to have lost touch with motherboard, memory and graphics card technology.

  12. These helped me by jalefkowit · · Score: 5, Informative

    I have found these resources indispensable in figuring out how modern CPUs and GPUs compare to each other:

    ... primarily because these tables are dynamic: find the part you're currently using (or want to use as your baseline for comparison) in the table, click on it, and then all the other parts in the table are immediately color-coded as to how much of a step forwards or backwards they are from that part, based on a normalized performance rating.

    (It's pathetic that the marketing departments at the companies that make these things are so incompetent that we need tools like these to sort out what exactly they're selling us, but until they get on the ball I'm glad these tools exist.)

  13. Only 2 components worth researching... by denzacar · · Score: 5, Informative

    Motherboard and PSU. Don't try to save money on these two by buying cheaper.

    Everything else is determined only by how much money you have to spend.
    Also, everything else can be upgraded/replaced without having to replace other components.

    Pay close attention to PSUs 12V amperage - don't buy cheap Chinese ones that have hundreds of theoretical Watts but give only about 20 Amps on 12V.
    12V is for all of your coolers, hard-drives (including external ones), optical drives and anything else you attach to it that has a motor or movable parts.
    Buy ULTRA or Corsair (if you can't afford a ULTRA).

    With motherboards, pay extra for the Deluxe or Pro model - however they call it.
    Compare it to the "regular" version of the motherboard.
    If it looks almost the same with maybe another PCI or USB slot added - the pricier one is the one that actually works as intended/advertised.
    The cheaper "regular" model probably couldn't quite cut it, so it got downgraded from the original intended specs.
