Newb question..

Hello, my name's Mark, and I'm building a new gaming rig.
I told my friend about this, since his brother has a cook gaming pc which is awesome.
I told him I'm getting the i5 2500k @ 4.5 Ghz, but he said that it's really slow for a processor. He said that if you divide 4.5 by the 4 cores you get 1.125,
and he says that thats how fast the CPU really is.
So please tell my friends he's a nub, and that my cpu really is the best bang for your buck and actually one of the best arround.

  1. Your friend is an idiot. What is a "faster" processor for he?
  2. Well his brothers rig is arround 2 years old.
    So I told him unless he had spent 1200 euros on his cpu it wouldn't be better then mine. But he wouldn't believe me, but now I've shown him a benchmark of the i5 vs the most expensive i7 intel sells now, and the were almost equal.
    So when I overclock mine it'll probable even outperform the intel i7 990 extreme something something right?
  3. Do you want prove that your CPU is better?

    Download SuperPI in both rigs from here:

    Run it and select SuperPI 32M test, run it with your rig at 4.5GHz and then on the other rig. At the end, compare results vs price and you will find that your CPU is a lot better.
  4. The stated clock speed of a processor is always set at the clock speed for each core on the processor. So if we list a quad core processor of having a clock speed of 3.3GHz like the Intel® Core™ i5-2500K that is the speed at which each one of those 4 cores can run at. Due to changes in microarchitecture and new technologies like Turbo mode an Intel Core i5-2500k will outperform any processor from 2 years ago in both single and multi-threaded applications.

  5. It would be a better analogy, though still ridiculous (it's just not the same thing), to multiply the cores. Four cores at 4.5 ghz makes 18 billion total cycles per second, 18 ghz.
  6. With the same analogy:

    i5-2500k @ 4.5GHz = (4.5GHz) / (4) = 1.125GHz
    Athlon II X4 265 @ 3.3ghZ = (3.3GHz) / (2) = 1.65GHz

    Nice, my $72 CPU is more fast that your i5-2500k :lol:
