The choice of processor used to be pretty straightforward. You had AMD or Intel, sometimes with a couple overlapping options from each company. With multiple platforms from each company as well as varying features, it can be difficult to determine which CPU you really want to purchase for your system. Over the last few years, things took a turn for the worst - even without the mobility options for Athlon 64, there are four desktop Athlon 64 3200+ variants (and that's just the tip of the iceberg). We felt that it was time for an overview of all the currently shipping processor models, as well as a look at the pros and cons of each model.

Before we get into the details, we want to make it clear that this is not intended to be an all-inclusive processor article. Information on many of the older processors can be found in our last CPU Cheatsheet, and this is intended partly as an update and partly as a more focused look at each model. We aren't going to go into details about every single CPU that you might find for sale right now; we're more interested in the mid-range and higher processors to be honest, as the budget chips are mostly last year's mid-range chips.

One of the key areas of interest is still something of a future release. There has been quite a bit of coverage recently about the dual core solutions from both AMD and Intel. At present, none of the dual core chips are really available (other than in OEM systems), but it's important to keep them in mind before you spend hundreds of dollars on a CPU that could be totally outdated in a few months. If you haven't already, you'll definitely want to take a closer look at our Dual Core Performance Preview.

In order to tie all of this together and bring it back to the real world, we're going to be giving our opinions on upgrade options for most of the processor platforms. This is not meant as a definitive statement of when you should upgrade and to what you should upgrade - only the individual can really determine that. Instead, it is intended as an overview of what tasks work well on various platforms and when you may find a platform inadequate for your needs. Some of you may find this information helpful, while others might simply take it as common sense. Nevertheless, we receive numerous emails every week asking for such advice, so we hope that it will prove beneficial.

For those of you who don't have the time to track every single CPU on the market - unlike some of us - we have a few tips and hints that can help you get the right processor. Not only will we look at the core names, but we will also delve into some details concerning the SKUs, or Stock Keeping Units, of several processors as well.

    'Emphasis. Im not a loreate of writing style. Both writing and speaking converge sometimes. Double quotes is 'quoted,'quoted written"".

    Since syntax of computers with parameters etc,in for example 'DOS will use computer langauge etc,I dont use them in practice ':) for example.

    Might find a more 'legal' way for writing,but doing so is just as much a 'program,so......

    ........if you weren't speaking(writing) to me. Never mind.

    ....... Get in trouble lots for not having correct usage. But cant edit stuff easily or 'proof it,such that looks same way as 'studied authors/article writers.

    The Anandtech forum here,makes a brief reply look long and out of place. Didn't mean to scarf it up.
    Think the balance is in what your trying to say when commenting.

    What's with all the extra apostrophes (') you keep putting in your posts before the words?

    "" As for components, PCIe and DDR2 are definitely not necessary for a computer. They may help in certain tasks, and they may be more "future proof", but if you were to set two PCs next to each other, one with AGP and DDR and the other with PCIe and DDR2, most people couldn't tell the difference without opening up the control panel."""

    ..idea being it makes no difference the question of 'can a hippopotamus swim"". Perhaps maybe both you and me know the answer. What makes a difference is it is still a valid question. Wich has a definite answer.
    Problem being,spend more or less for your computer ""? People arent buying computers to give you their money. Then - I dont want performance based on a cost of a machine. Information is necesary to tell how 'lucky I will be as a purchaser. Where participation of technology is the relationship of buyer. The 'platform,AMD,Intel,both have a signifigant performance to that participation. I have not yet seen the stats in wich show'd other than relationship between 'highest tier,and 'others. Would like to see,all the performance stats for the platforms ,for anything other than FX,or EE processors. (make it 775,939).
    Again,these are really affordable,very good performing machines,new technology,and 'upgradable to a future 'partipation of the technological accesory.You could for example,simply take the two 775,or 939 pin 'platform as basic criteria. Then tool the charts consistent to all other processors excluding FX,or EE. If you look,the same person w/o knowing a frame rate,from the control panel,is the same person looking at the same frame rate(Pcie,Agp). The person looking at memory output,is dealing with the memory output they have on the platform with the processors. Different apps,have different stats as to how they will perform. This pertains to the same person utilizing them to their participation to it.
    AGP/PCI express ...same affordable graphics cards. Motherboards ..same affordable motherboards. Memory same affordable memory.
    But I have yet to see anybody do the changout for the processors. The affordable processors.
    Sure I know that if you did this on a monthly basis it wouldn't show a great deal of difference. But even giving the same info over again,leaves room for a highlighted proprietors system accesory.,though not the criteria for the comparison. Since there are always someone 'new,to surmise their systems,it would be certainly good for them.

    Making a mistake to leave the criteria out simply to deem 'cost analysis. Since we know these are performance,better than that before - the technology still has not been given its air of dayview. At least not with the processors. Knowing you could do this is just well enough an upgradable powerful platform. Leave 'cost analysis to THAT criteria. Fact is they are affordable,they are powerful,they are participation in new better technology.
    Might consider applications when dealing with the hardware facet such as 'dual-channel memory/non-dual channel memory.Again along with the ''multi-tasking''.
    The big deal however is the 'fact of making the stats for the processors.AMD has been way too expensive.Affordability is just coming on line.Same goes with Intels 'Prescotts. Maybe the processors will show distributive results across the platform.

    ..........had to look up hippopotamus. Hi ya. I'll be reading. Really apreciate the reply here. This WAS a question for a processor to resolve.

    A budget system doesn't imply that it's a slow PC by any means, but there are certainly tasks which will bring a budget system to its knees. Gaming is one such task, but video editing and content creation in generaly really require more than a typical budget PC. We also had the Gaming Guide at the end of November, which included PCs for the Low, Mid, and High end price ranges. That was intended as a Christmas computer Guide, and it covered all the options we feel are important.

    If you don't want a good graphics card, I assume you understand that the Buyer's Guides are merely meant as recommendations. You can easily remove the graphics card from the equation if you want. We probably could do a monthly Buyer's Guide covering each segment, but some times very little changes.

    As for components, PCIe and DDR2 are definitely not necessary for a computer. They may help in certain tasks, and they may be more "future proof", but if you were to set two PCs next to each other, one with AGP and DDR and the other with PCIe and DDR2, most people couldn't tell the difference without opening up the control panel.

    Our Guides always try to make it clear that if you're happy with your computer, there's really no reason to buy a new one. Upgrade when *you* want to, not just because a new technology comes out. Many people and corporations are still running Pentium III and Athlon systems with 1 GHz or less processors, and for the most part they're okay with the performance level offered. I still wouldn't suggest anyone actually buy such a system NEW right now unless it cost less than $100. (I just gave away my old Pentium 3 1.4 GHz PC with 512MB of RAM to a friend - it had become useless to me, as I had better PCs available to replace it.)

    Anyway, Tujan, you might not want to read the Mid-Range to High-End Guide when it comes out next week, as it targets the $1500+ price range. :) Kidding, of course, but please realize when you read it that we're not saying people HAVE to spend that much. I'll be starting another Budget Guide soon as well, for those interested in the price/performance options.

    Buyers Guide Mid-Range,January 2005
    Author Jarred Walton..

    Just one more tug at your attention here one tiny moment. This article came out in January 2005. It is well put together,and sums up some of the same components that will go into todays computers. Although the selection will be of course those included to June 2005 if anybody was to include them.

    The technology space is the same pretty much,pci-e or no pci-e,socket/socket wich socket,and where art thou processor,and memory,where oh where is my memory,or what did I do with it. And whichever be the case.

    Comment being this article was out in January 21 2005 ! The very same day,probably to the hour that those xmas credit card bills became due. We needed this article a month before xmas,....actually we need this article every freeky month. In otherwords the timing of this article couldn't be worse.

    And these are performance computers. They are not 'low-end,just on the count of a lesser priced video card,or lower amount of memory/processor type. Something is very wrong with the insultive frequent in the likes of "Longhorn" Dec 2006, AMD DDR2 Feb 2006,Intel 945g Motherboard 250$,AMD DualCore 500$,Intel EE 950$. Ah crack corn and dance XBox now.

    While I couldn't bett against them I could certainly fit between them.So some of your stories at least should 'light up for somebody. I just dont see the benifits of the change involved in being informed about it lately. Since nobody is showing us the score of that performance information. So at least a person could be 'lucky at that performance level.

    I just find it quite insultive to know Im being ignored. The chronology of presentation in statistics of performance of systems in articles couldn't be worse.

    Wont bother you with this again. Said my piece,geuss thats well enough.

    JarredWalton,..Hi ya..ufphhhh - your the author here (LOL).
    The point Im trying to let you know about is that for a new buyer,939,and 775 pci systems,are 'performance systems.The lack of memory,or want of a processor does not mean that we as a buying public are gathering low end dirt.
    Your article is detailed for the processor.But marketwise,lets be honest about what you know about them. You or I can put them together for under 1300.00,so why should I be insulted with being ignored to the use of the technology as a consumer.Being told,I have a low end system,or a 'value system - simply because I didn't stuff a gig,or a 400-500$ graphics card into the system.
    When you look the conspiracy gets deeper in that for both AMD,or Intel it will cost 500$ min,to keep with the dual cores on your platform !!.
    AMD has been very expensive,period.The platforms have been mixed (no-pci,yes-pcie). With Intel still being just as bad now,with its 'new motherboard etc.
    Mean 18mos on the market then your gone ? Think that was 18 months to market,two day (Ill exajerate) gone on the shelf.

    Your story is fitted for everybody (Hi everybody), processors. I think everybody is waiting to go as it is. Nothing to do with YOUR story if you want to say so. (if you say so must be so). Still,I would like to see the benches from all like made processors besides FX,or EE on the similar platforms.

    Wouldn't hurt if sales floors had outlines ,with pictographs,detailing differences of socket types ,boards/bus,mem/mem ram types.Ya know,say you got a good deal"...,for a AMD 754. Nevermind they dont use PCI-e (do they have pci-e?),..or dual channel memory for some of the boards.

    Mean if you know a marketing guy,tell him to put some balls on.The consumer needs the power in todays machines.They are upgradable.They are powerful.They are participation to new technology.

    Thanks for reply.Have a good day now.

    My own take on the naming scheme is that it is strictly for Joe-Six-Pack, those of us who post here (thanks to the AT staff) have a much clearer idea of what they actually have/do.
    That said, the question the AMD model numbers actually corelate to the chips performance level?
    AMD has said that to arrive at model numbers, they test the CPU on a battery of commonly used apps and compare it to the original Athlon 1GHz.
    I have actually never seen an independant reviewer attempt to emulate this to see if their numbers are justified or not, but I would be most curious to see the results! (hint, hint...)

    Tujan, I'm not sure what that has to do with this article. This wasn't intended as a Buyer's Guide or Price Guide. We're talking about what each aspect of each core means (in a simplified manner). We recommended some upgrade options, but nothing we recommended was more than a few hundred dollars, and it wasn't meant as a "you MUST upgrade" but more as "you might consider upgrading if...."

    My comment about not getting the point of your post #37 was genuine. You say you're being critical, but I don't see how your comment is related to this article. If you can point out specific statements we made that you have problems with, I'm all ears. Right now, I'm simply confused. Sorry.

    I understand how the generic names can be disapointing to a "techno-snob" (LOL) like yourself. I just got carried away with my post and didn't want to just delete it after writing so much. I must not be as much a "techno-snob" as some :) BTW, nice crib sheet (I mean article).
