    pyprime not good for ryzen ?

    It depends, Zen3 and Comet Lake are basically on par (architecture wise), the main problem there is that most of these AMD CPUs are limited to about 4000MHz on the ram (because of infinity fabric limitations), sure, you can get it higher, but that will increase latency which will seriously hinder performance; your main avenue for increasing performance is tightening the timings and overclocking the CPU itself.

    Older zen based architectures don't do as well, this is mainly due to the relatively high memory access latency and the lower maximum infinity fabric clock, this is also the reason I think Rocket Lake won't be as fast as Comet Lake and zen3 in this benchmark.

    I hope this helped! :)

    Hi, I was looking through the submissions to see how well the benchmark scales on other systems with different ram, and I noticed you got a relatively low score for your setup (which is basically the fastest PC you can buy at the moment); Since this is a new benchmark and people might not know yet what to prioritize, here are some suggestions to get a better results: You might want to get the FCLK/UCLK (infinity fabric and memory controller clock) to a 1:1 ratio (I'd start with 1800MHz, then try to get it to 1900MHz), then lower the DRAM clock to 2x that of the FCLK/UCLK. After that you can start tightening the timings, CL20 is quite bad, I think you should be able to get it to at least CL16, the results here will depend on your memory though, but generally the lower the better! Sorry for being annoying, good luck with your benchmarking!

    [WTB] 10900K or 10900KF

    in Sold

    The cheaper one? The 10900KF is a 10900K without the iGPU, and unless you need it it's gonna be the better buy, many disable it anyways when overclocking

    To be completely honest though I would wait for the 11th gen, it should come out fairly soon (about 2 months) and unless you need a 10900K right now it will be the better buy

    There is an issue with the supplied data file. when uploading data file

    in Support

    Posted

    I'm updating my benchmark to use encrypted datafiles, and I get this error when I try to upload something.

    Without encryption the datafiles seem to work just fine, but when I add it I get this error.

    I am using AES 128 CBC.

    this is the unencrypted .xml file

    datafile.xml

    and this is the encrypted one 

    datafile.hwbot

    when it goes public I will change the key, so here it is 

    3778214125442A472D4B615064536756

    and the initialization vector  

    6E5A723475377821

    The iv has to be 16 bytes otherwise cryptodome, the library I use, launches an exception.

    this is the function that creates the .xml and encrypts it 

    def datafile(second):
    time = datetime.datetime.now()
    submission = ET.Element('submission')
    application = ET.Element('application')
    name = ET.Element('name')
    version = ET.Element('version')
    score = ET.Element('score')
    points = ET.Element('points')
    timestamp = ET.Element('timestamp')

    name.text = 'PYPrime'
    version.text = '1.4.1'
    points.text = str(second)
    timestamp.text = str(time)
    submission.set('xmlns:xsi', "http://www.w3.org/2001/XMLSchema-instance")
    submission.set('xmlns', "http://hwbot.org/submit/api?client=pyprime&clientVersion=1.4.1")

    submission.append(application)
    application.append(name)
    application.append(version)
    submission.append(score)
    score.append(points)
    submission.append(timestamp)

    file = open("datafile.hwbot", 'wb')
    file2 = open("datafile.xml", 'wb')

    key = b'3778214125442A472D4B615064536756'

    iv = b'6E5A723475377821'

    cipher = AES.new(key, AES.MODE_CBC, iv=iv)
    file.write(cipher.encrypt(pad(ET.tostring(submission, xml_declaration=True, encoding="utf-8"), 16)))
    file2.write(ET.tostring(submission, xml_declaration=True, encoding="utf-8"))
    file.close()

    I've been on stuck on this thing for about 10 hours, I hope someone can help me.

    Benchmark development problems

    Is there a suggested API to get all specs in the computer? I am using python to make a multi platform benchmark (yes, python) and I have sorted most of the basic things out, in fact you can try it out (its called PYPrime, you can find it in the benchmarks section) but there are some, SOME, security issues I'm working on, being open source it's way too easy now to cheat, so I am now implementing datafiles to add some security, but I still can't reliably get the system specs (like memory timings, memory speed, motherboard vendor) ,heck, even the CPU is a bit hard to find in some cases.

    I would like to avoid using external libraries to make the installations as simple as possible, that's why I used this kind of things: 

    def get_processor_info():
    if platform.system() == "Windows":
        print('CPU: ', platform.processor())
    elif platform.system() == "Darwin":
        print('CPU: ',
              bytes(subprocess.check_output(['/usr/sbin/sysctl', "-n", "machdep.cpu.brand_string"]).strip()).decode())
    elif platform.system() == "Linux":
        command = "cat /proc/cpuinfo"
        print('CPU: ', subprocess.check_output(command, shell=True).strip())
    return ""

    The worst part is that I can't seem to get access to the API documentation because this weird problem 

    <response>
  <status>error</status>
  <message>Unable to process data request, please contact HWBOT if this issue persists.</message>
</response>

    that appears every time I try to open the link, sometimes It happens when I try to view some benchmark submissions
