Comparative CPU Benchmarks From 1995 to 2004 320

Lux writes "The guys over at Tom's Hardware Guide have been busy recently! They've compared over a hundred different architectures dating all the way back to the Pentium 1 in one huge benchmarking effort. Looking to upgrade an older system? Unlike most benchmarks, which compare modern systems to other modern systems, these charts can help you figure out if the cost of upgrading is worth the speedup or if you should hold off for a bit longer."

      A 487 math co-processor will turn it into (almost) an equivelant pentium.

      Actually a 486+487 still has enough juice for a homebrewed linux firewall/router, and you can get boards with chips for a buck in the throwaway bin at my local computer shop.
      • The 486 has had a built-in math coprocessor ever since it debuted. After the 486 was around for a while, they made a stripped down version without a coprocessor called the 486SX. The plain 486's were called 486DX.

        You could get a coprocessor for the 486SX, but not the DX. From what I've heard, the original 486SX's were actually re-badged 486DX's whose math coprocessor unit was either not functional or just disabled. When you bought the 487SX "co-processor" you were actually buying a fully functional 486DX t

        • When you bought the 487SX "co-processor" you were actually buying a fully functional 486DX that disabled the other CPU on the board.

          Correct.

          And for the 386, the 386SX was like a 386DX but it was crippled by a 16-bit bus instead of a 32-bit bus. Which made them the same speed as a fast 286.

          Neither 386SX or 386DX had math-coprocessors. You had to add them on later.

      • A 486+487 is still far away from a Pentium.
        Anyway, how will a math coprocessor help firewall or router software? It will help you to play Quake I, but will make no diference for a program that is not intensive on floating point math.

    Artificial benchmarks tend to exaggerate minor differences in speed that aren't noticable or relevant in human time.

    The best analysis of whether you should upgrade is a subjective one. Sit down at the computer. Does it do what you want or not?

    Benchmarks tell me my Radeon 9800 is horribly out of date and imply its too weak to play any modern games. But I know from experience, that's bullshit.

    Back when I upgraded my 386 16 Mhz, I told myself that I'd upgrade every 10x in performance gain. I upgraded to a Pentium 90 Mhz, then to an Athlon 900 Mhz. It seems that with the recent troubles of AMD/Intel at breaking the 4 Ghz barrier that I won't keep my 'promise' anytime soon, sadly.

    How will they keep their market alive if they can't upgrade the performance? Its not like CPU chips are burning easily anyhow... so why get a replacement if the performance gain is not worth it?

      With multi-core chips and on-die memory controllers, the benefits of performance will be felt, even if the clock speed is constrained to 4ghz for now.

          Best example is Sims 2. If you have a T&L Video card, you can run the game with a 900mhz processor. If you don't, you need a 2.4ghz processor.
        • Most games are multi-threaded just a little bit, but not enough for multicore to help rather than hurt. They'll certainly consider multicore in next generation titles, but most titles today aren't anything like cpu bound (they're all GPU bound).
      • Because megahertz is not totally where it's at, contrary to Intel's marketing hype.

        Somewhat true, but historically most cpu improvement was due to clock speed increases, which have slowed way down.

        CPUs just aren't getting faster like they used to. We've hit something of a wall. It would be interesting to seem Tom's benchmark charts plotted against release dates.

        The move to multiple cores is a white flag waving. Two cpus aren't in any was as good as one that's twice as fast.

    • Another one of those people who think that clock speed equates to performance. :sigh:

      I'd take a 1 Ghz proc that executes 5 ops/clock over a 3 Ghz proc that executes 1.5 ops/clock, if I were given a choice. Price is also a major determinating factor for me.

    I only see x86 CPUs. What about the PowerPCs, SPARCs, MIPS, Alphas, ARMs, and so on?

    For instance, the m68060 was the first consumer level processor with branch prediction and branch folding, superscalar dispatch, and real-world throughput of more than one instruction per clock cycle. Except for floating point where it performed only modestly, the m68060 seriously outperformed the Pentium in spite of only having a 32 bit data bus as compared with the Pentium's 64 bit bus. Isn't this significant in illustrating the influences in processor architecture?

    The article is a bit slashdotted but it looks like it doesn't go back all that far.

    Just a teaser, I have been running a collection of benchmarks since the Pentium 90.

  • but I'm sure that I read a similar article at tom's this year comparing x86 CPUs from ~386 to recent systems.

    IIRC they decompressed zip files and encoded video stuff among other things. It's quite impressive to see a fairly modern CPU performing the same task in minutes which used to take several hours on one of those 'antiques'.
  • If you installed Intel's PII Overdrive for Socket 8 mommyboard you could obtain MMX, but that was the only way.
  • I've got a Duron 1200 and am trying desperately to upgrade to an nForce2 / XP 3200+.

    After a bad board and bad processor (from partspc!) blew a RAM chip I had bought for it, I ended up RMAing all three of them, likely with little or no compensation coming my way.

    So here I am, after Christmas, stuck with one functional 512 stick of PC3200 Corsair after have spent $400 or more on my upgrade fest.

    That's why I don't upgrade very often, besides the lack of money. Because I know that there's a good chance what
  • People don't really detect a perceivable performance boost for less than 25% more actual performace. And the perception of that 25% varies wildly from 'fneh' to 'wowieeeee'.

    But I'm talking to a bunch of gamers for whom that last 0.4% performance boost is worth more than a hot cheerleader full of X.

      These are the same people that get into squabbles over which display adapter is better when A gets 150FPS (frames per second) and B gets 140FPS but with better double-dodecahedron rendering or whatever. It makes no difference to them that most human eyes cannot distinguish between 40FPS and 80FPS, let alone anything above 100. However, if the [abstract and wholly meaningless n
      • I must disagree with you on the "most human eyes can't distinguish the difference between 40 and 80fps." This may be somewhat more true of movies which are made with motion blur that blends the frames together. But you can certainly still tell the difference for the better when a movie is captured at 60fps rather than 30. Its not as big a difference as changing the framerate in a game is due to the motion blur but its certainly more visually pleasing when a video is captured and played at a higher framerate
    • Actually, a worthy performance boost should be an order of magnitude (10x).

      I don't upgrade until there's a computer 10x better than the one I have right now, and available at a good value.
  • The primary end-result of the evolution of this commodity hardware is the fact that expensive software is now just obsolete - plain and simple. Ten years ago, there was a justified price premium associated with state of the art software algorithms. I still see these zealots for the DB companies raising these red-herring issues as to why every organization should still spend hundreds of thousands of dollars on expensive DB software. With the evolution of hardware the way it is, any credible SQL DB Engine co
  • If you take a look at the big chart, why is it that the clock speeds have increased by ~10 fold from start to end, but the front side busses have only increased ~5 fold?
