    coffee lake architecture, so it still gets a slow down with meltdown and spectre patches right? Can you confirm whether these were turned on in your testing or left off so it can be compared directly to the older tests in the charts. If the latter, what is the performance drop once they are run with the MD + Spectre patches activated?

    Explain how does PiFast benchmark help us in the real world?

    It has an OK correlation with most real world tasks that are not heavily threaded.

    As much as any artificial benchmark meant to represent the performance under a task utilizing certain types of features or workloads on a CPU.
    As kalniel said, PiFast is single-threaded, and so offers a relative performance comparison for applications which are entirely or mostly single-threaded.
    That still applies to a lot of games for instance.

    While I don't broadly disagree with you I have to say the old 'most games are singlenthreaded' had been used as a defence for focusing on these kinds of benchmarks for too long. Even IF a modern game is single thread heavy the main thread still uses much more of the functionality of the core that deviding 23 by 7 over and over again. I really don't think there is a direct comparison, approximation sure, but going by the pifast scores alone you'd get a very different picture from actual gaming benchmarks.

    bump on this - any feedback Hexus?? Given this is a binned chip of the old variety I presume it doesn't have the hardware fixes built in, and is still vulnerable to variants 4+5 even if they are?

    Hi,

    The Meltdown and Spectre patches were enabled for all CPUs in this line-up, thanks.

  10. Received thanks from:

    I like one of "the bad" points is NO COOLER in box...really? Like a cooler from Intel is going to keep a 5GHz chip cool

    It should, not having something up to the task isn't an excuse for giving up. Even if it needs an integrated water cooler, an Intel approved one should be in the retail box. If it needs a big air cooler, one should be provided. It should be there and it should be up to the task, there are always OEM chips to be had for people who want their own cooling solution.
