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?"

Don't think of it as a flame---it's more like an argument that does 3d6 fire damage
Check out http://www.cpubenchmark.net/ and http://www.videocardbenchmark.net/ With a pinch of salt you can make a relevant decision based on those two, even if Googling around would make your decision even better. .
I usually find the advice from tech report's periodical System Guide to be very useful and relevant.
Their latest report came out a couple of weeks ago. They focus on a range of options at various price points and requirements.
sorry to attempt to answer your question and not shill Apple.
bah!*@%!
A Core i5 750 costs more than any current AMD desktop processor, so that makes no sense. I can get a quad-core Athlon II for half the price of an i5 750. Sure, it's slower, but it's not slow. Also, it drops straight into my old AM2 motherboard (with a quick BIOS upgrade). Try doing that with Intel.
Remember that this shit completely changes every few years. I used to build PCs for myself and my school as a kid (386/486), then couldn't affort to for a few years, then had to start reading PC magazines when it finally came time to afford a new PC (Pentium 2/AMD equiv). Fast-forward a few years to my next major upgrade, and I'm reading Wikipedia instead of the mags, but I'm still pig-ignorant of the latest tech until I've figured out whether AGP is still current (nope) and which of DDR2/3 will be needed, how many cores are worthwhile, etc etc etc.
Maybe it's easier for those who do hardware support or deal with servers (I mostly deal with routers/switches/firewalls), but I get completely left behind if I ignore the PC components market for more than a few months.
The problem is that this doesn't work when you want to find out if it is worth to upgrade or not, as benchmarks always only compare the newest stuff against the other newest stuff, not against your years old hardware at home. Even worse is the special OEM hardware that you sometimes get (Geforce 7600LE for example), as that doesn't show up in benchmarks at all. And on top of that there are of course also compatibility issues, like will this graphics card work with my old power supply and such.
Long story short: I have basically given, its to much trouble to search for updates, so instead I just run what I have till it breaks.
Another reason to choose AMD over Intel, Intel has some CPUs that support the new virtualization extensions and some that don't. AMD OTOH supports the virtualization extensions across the line. That and AMD quad cores are stupid cheap now. Unless you have a really pressing need for a really high end CPU get the AMD.
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.
The Core i5-750 is only $200. If you're not willing to spend $200 on your CPU, you have no business building a PC instead of buying one.
B.S.
What the point of wasting $200 on CPU when you can get for >$100 a CPU which performs in real world >5-10% slower?? And most applications (even games) are pretty happy even with half/quarter of the performance???
I'm not per se against the Intel CPUs. Some of their CPUs are cheaper and faster than the AMD ones. But for whatever reason, at least in Europe, the MBs for Intel CPUs are on average 10-25% more expensive than those for AMD CPUs. And upgrade-ability of the AMD systems is magnitudes better: one can get cheap CPU today and upgrade it few years later.
All hope abandon ye who enter here.
AMD capable motherboards tend to be a lot cheaper, that can easily save you enough money on a highly capable gaming system to replace the HD with an SSD, and that will have far more influence on game performance then the Intel chip will. In gaming, AMD performs a lot better. Always make sure to read the entire review of a CPU for the stats that are relevant to you. For instance, if you once in a blue moon use Office and never use a database on your PC, what do you care about how fast/slow your CPU is at them?

Perhaps the point of his question to slashdot....you know, a technical news/information site, with a technically savvy audience...is to get an answer, not to get excoriated for having the question?
You know, your point "3. Research what components will achieve the expected result."
I think his question is valid - it used to be a fairly simple task to equate processor speed with power, to come up with a reasonable expectation of performance for a task. But to everyone (except, apparently, you), it perhaps isn't intuitive that a quad core at a lower speed will or won't perform better than a duo core at a higher speed. (Answer: sometimes it will perform better, sometimes it won't. How is he supposed to know, oh swami of computer tech?)
So you could offer actual advice or click through to the next news article, instead of bitching that someone asked a very valid question.

I know Macs have model numbers and I know they have CPU's which also have model numbers. I don't know any of those numbers.
You can hand in your five-digit Slashdot ID now.
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.)
Read my blog.
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.

If you're playing hot new games, a hot CPU is handy. So is a hot video card.
Not true. You need a better cooler.
