Ignore them. They don't bear the slightest resemblance to reality. F. |

That's a little harsh. They mean something, just not as much as we'd like. |

??? You publish a set of benchmarks.. Now what?? What is Your Question? Do You want us to make a guessing game? (We try to figure out what CPU You are using based on the figures). This idea is because You have hidden Your Computer.. That must be it :) because without further info and a question, this is all I can think of. sorry. Now, go and donate $10 to SETI@Home, and get Your little green star. :) ChrisD |

But how much credence can we give them when my Q6600 running XP Home overclocked to 3336MHz reports 3273 FP and 7476 Int whereas another Q6600 running Vista and not overclocked (i.e. 2400Mhz) reports 6862 FP and 10828 Int? Just didn't see much point encouraging a thread for swapping figures that are meaningless for comparing different machines. F. |

I can't comment on the specifics without a whole lot more detail on this specific case. But I can comment on the arguments over benchmarks over the past six decades or so. A benchmark is a synthetic application designed to predict performance in the real world. It depends on a lot of factors, including how well the benchmark models the real world instruction mix. If you're writing benchmarks in a high-level language, it's harder to produce a portable benchmark because compilers optimize. A really good optimizing compiler __should__ remove the actual benchmark code completely, running the "benchmark" in zero time. What it does mean is if you take your machine running at "stock" and get the benchmarks, then increase the clock speed by 20%, you should see a roughly 20% increase in the benchmark numbers -- holding everything else equal, and assuming memory performance isn't measured (because the benchmark fits in the cache). It doesn't mean very much when comparing apples and oranges (dissimilar systems). |

I suppose you're right, without knowing sytem specifics, they do appear meaningless. Here, I use my PC and my partner's PC (when available) to 'crunch' - they're both 3.2Ghz P4 Prescotts, on i875P chipset boards with 2 Gig of RAM. The 'Benchmarks' reckon that my partner's PC is a tad quicker, but my PC 'feels' quicker and always proves to be a bit quicker - especially when running on-line games (WoW) in spite of the older HIS X850XT Graphics card, compared to their newer HIS X1950 Pro....... Perhaps the RAM in my PC is playing a bigger part in this - OCZ Platinum EL, as opposed to 'standard' timed Hynix. Don't take life too seriously, as you'll never come out of it alive! |
