Which CPU Is Tops in Price/Performance?

mikemuch writes "You can spend 150 bucks or over a thousand on a processor, but how do you know which gives you the most power for your money? It's a little like MPG for CPUs. ExtremeTech's Loyd Case does extensive benchmarking on twenty-three current desktop processor flavors from AMD and Intel. While of course most folks won't make dollar-efficiency the sole basis for their chip decisions, it's interesting to see which CPUs get you, for example, the most frames per second in Far Cry for a dollar." From the article: "Take PC games, for example. The cheapest CPU available may have the best frame rate per dollar ratio. But you still need an adequate frame rate for an optimum gaming experience, and the cheapest CPU may not deliver that. On the other hand, office applications are generally not as sensitive to raw performance, and the lower cost processor may be better. It's all in what you do."

      There is an interesting article at pcworld ( http://pcworld.com/news/article/0,aid,122700,pg,3, 00.asp ). It states that both AMD and Intel have low cost 64 bit microprocessors out(AMD Sempron 2200+, Intel Celeron D.) The AMD Sempron cost only $60 so it is less than half the cheapest microprocessor reviewed here. I would like to see one of these reviewed using a 64 bit Linux operating system with only 64 bit programs.

    I like how after the full analysis, the ultimate result is that there's really no answer. Cheap is slower, expensive is faster. Dual core has poor support in Windows currently.

    Not exactly surprising, but I wonder how much of that is tied to the OS (f'rinstance, dual core kicks ass on OS X for processor-intensive tasks). Similarly, I wonder how much of it is simply benchmarking the wrong kinds of things. Comparing "office productivity" is mostly useless, as they say in the article, yet it still gets benched. Similarly, graphics, while still relying on the CPU, uses the GPU more and more.

    I've found in my own little "tests" that heavy-duty rendering and long-term CPU processes are really where the benchmark tests are at. Fire up something like VirtualDub and compare the time it takes to transcode video files, for instance, or use ffmpegX on Mac OS X. That's where the real CPU tests come into play. Not office and games.

    (I'd also be curious to see what happens if you start switching around operating systems. Test to see if an AMD chip and NVIDIA board is better running a Linux flavor compared to Intel, for instance).

  13. The analysis is nonsense by Saunalainen · · Score: 5, Interesting
    Suppose processor A costs $100 and gives 100 units of performance, but processor B costs $200 and gives 150 units of performance. Then the cost per performance is 1.0 unit/$ for processor A and 0.75 unit/$ for processor B. Right? WRONG!

    Both of these processors need $500 of ancillary equipment in order to function. Therefore, a system with processor A gives 100 units for $600, or 0.167 units/$, whereas processor B gives 150 units for $650, or 0.231 units/$. This analysis shows that processor B is better value when speccing out a new system

    But what about the case where you're just upgrading your cpu? Well, in that case it's moot to compare the AMD with the Intel processors, as you would need a new motherboard too. But simply dividing the performance by the cost of the cpu is meaningless here, too, because staying with your existing processor ($0) would give you a performance/price ratio of infinity.

    Conclusion: you have to calculate your total outlay in order to figure out which cpu is the better value.

    Well ... there is no boundary work, no (mechanical) forces acting over a distance, and no shaft work.

    I'd say that a processor produces ZERO mechanical work.

    When you look at a computer as a whole, you put in electrical power, and get out heat (with only a tiny amount of real 'work' from the fans). So from a thermodynamic standpoint, it's just an overpriced, inefficient spaceheater.

    That's not uncommon. When a company doesn't want to carry/sell a product, instead of saying no, they just price themselves out of the market. That way: a) The customer never hears a, "no", which is something to avoid. b) If someone actually does buy from you at that price, what the hell, you made a buttload.
    I ran into this on my home printer. I bought an HP 2550 printer (for doing all of the printing for my wedding). It comes standard with 64MB of RAM. This is plenty until you start sending graphics to the printer. So to stop the "Out of Memory" errors, I decided to upgrade the memory. The printer would handle an extra 128MB SODIMM.
    Price from HP: US$800

    Price from Kingston: US$50
    And, it only took me moments to find the right part with Kingston's website (they have a really nice memory finder). Also, Kingston offers a lifetime warranty and puts out a solid product, so no worries about a fly by night company.
    So, in the end, I got what I wanted and HP got to stay out of the memory business, without ever explicitly telling me "no".

    In a way he is right. The programing for a 486dx2 was leaner and faster then the stuff availible today. It seems that you upgrade a slow and slugish computer for a faster new one and after years of program upgrades, the bloated newer stuff apears to run as slow as the computers you upgraded. Windoes runs slower (even though they say it is faster) with every upgrade, office applications tend to do the same. Even antivirus (especialy symantecs offerings) end up using more resources and cycle and give the apearance or running like an older computer.

    In fact, i just pulled out my 486SX/33 computer running windows 3.11. loaded a couple programs i used then and still use today. Even thought the newer programs have become more powerfull and such, the 3.11 486 loaded a program at about the same speed and apeared more respncive to menu commands then the new program on my P4/2.8gig machine.
