    I bought a really nice intel xeon eng. sample cpu. They pop up sometimes on ebay.
    But this one is really special..
    Anyone have experience with such CPUs?
    They are selected chips, much better as retail ? They are limited in such way?

    Wait, that's 18 physical cores, 36 logical ones with HTT? Or is it reporting erronerously?
    [EDIT]
    Turns out such xeon really are marketted, I didn't know! Now find a motherboard with 2 such CPU and you're the king of parallelisation.

    yeah its a broadwell :confused:, x99 boards will work fine. Really nice with ddr4-2400 support.

    Id love to have a machine with more than the 8 cores I have. That plus google fiber would make video work much better.

    which 8 core you use?

    I do research IRL and we got those awesome 5 years old desktops in the lab, with two hexacores xenon with HTT and 16+ GB RAM. 24 threads is almost impossible to clutter no matter how many stuff is running. I totally plan on salvaging one when we trash them. The electricity bill though...

    i still use a i7 5820k, and its perfect.. But i got this one now really cheap, i cant resist..
    Good thing is i need no new board its a switch on cpu and go...

    I have 2x Xeons with 4 cores each. Two machines running so technically thats 16 cores, but it isnt the same :p

    18 cores ? wow...
    Still running I5 3570K at 4 Ghz, it's powerful enough :p

    Unless you're doing very heavy calculations, virtualisation, or multiple video encoding in parallel, there's no real need for more than 8 threads. That said, of course everyone wants it.
    I for one use almost exclusively a 2cores/4threads laptop and it's perfect for anything bar gaming or computation heavy calculations.

    I use the aforementioned xenon setup for the real-time complicated calculations. Timing was such an issue that we had to split our 8 threads 6/2 between the two cpus, because 4/4 couldn't cope in realtime because of the electrical delay with the ram (the ram is closer to one of the cpu). HTT wouldn't help enough to warrant putting the 8 threads on the same cpu.

    there is no need for me , only nice to have ^^ Bought it becaue it was cheaper as the latest i7 x99 new, and its a engineering sample
    also made in usa ^^

    How much did you pay for it if I may ask?

    cheaper as a i7 5960x ^^
    a v3 18core xeon cost new around 5k$ and its 22nm ^^ so a good deal i think.

    We get engineering samples of micros and sensors pretty frequently, typically they are units from after the R&D phase, but before a unit goes to EVT and gets certified for resale. They usually have all the "hidden" features unlocked/documented (depending on your relationship with the vendor) and come with beta versions of the data sheets and reference manual. Sometimes we get samples in configurations that aren't ever going to be available to the public, to test feasibility of a design for the vendor among other things.

    Using them allows us to get the majority of the design done while the vendor brings the final product to market, and then we only have minor tweaks to make once they finalize their design.

    I have a couple Pentium Pro 133 Engineering Samples. Also I believe I have a 10186 ES CPU.

    None are cores happy like yours but I saw the topic. I think the upstairs WS has 8 physical and 16 logical cores though, AMD.

    Most consumer model engineering samples have much slower clock speeds than the final chip.

    Depending on the price, they can be a good deal sometimes.

    Also, evaluation chips can be rushed to important vendors for servers, those ones usually with the same specs as final. You see a lot of evaluation xeons that will be the same as final.

    Finding a previous socket with a next gen core is rare, like a few 1155 sandy bridge or similar odd makes.

    Well I went down cellar and fired up Bessy, it still boots and even remembered the date. I was shocked when I saw it said 4 x 200Mhz 1MB CPUs. I must have upgraded it back in the 90s but I found both DUAL CPU riser boards populated with 2 x 133 256K CPU's each. So I thought I had 2, but I have 4 of these KB80521EX133 Q0821 256K PentiumPro 133 ES CPUs.
