    Is Geekbench 5 a reasonable CPU benchmark?

    Posted: 06 Nov 2020 12:02 AM PST

    Hi,

    I've tested a few devices and wonder if the results are reasonable:

    1. The iPhone SE 2020 has such a high single core performance (1328 points), that only the i9-10900K (1388 points) surpasses it. All my other computers are rated lower. I actually cannot believe this.
    2. I've tested two MacBooks in macOS and Linux. Both show a much higher (>5-12 %) performance in Linux. I would not mind for 1-2 %, but 12 %? EDIT: At least different compilers are used on macOS and Linux (Clang vs. Xcode), so this could make a difference.

    My results are here: https://browser.geekbench.com/user/349816

    EDIT: The documentation for the Geekbench 5 tests can be found here: https://www.geekbench.com/doc/geekbench5-cpu-workloads.pdf I can see a lot real world stuff in there.

    Serializing PCBs across Revisions

    Posted: 05 Nov 2020 01:24 PM PST

    I was always put the board rev (like 'Rev (-)') in the silkscreen on the board, and leave a spot to write in a serial number.

    We made a first run of 5 boards, found a few issues, and fixed them in the rev A design. In terms of serializing the PCBs, I've always restarted at '1' with each new, rev, but it seems that continuing the count regardless of revs, seems to make more sense so there is never more than one board with SN 5, for example.

    On the flip side, in the case of continuing the count, I suppose that some sort of spreadsheet would be needed to know that SN 100 may not be drop-in replaceable with SN 150.

    So, what does the hive mind think?

    For over 10 years now, people have been saying that Moore's Law will end at the next die shrink, yet were still going strong. What gives?

    Posted: 05 Nov 2020 07:54 AM PST

    I'm sorry if this sounds slightly ignorant as I'm not nearly as knowledgeable about hardware as most of you are, but anyways, especially when speculation about 5nm processors began to grow around the mid 2010s people seemed confident that this was the absolute limit, yet here we are in 2020 with 5nm commercialization well underway and 3nm development making steady progress, which is predicted to enter commercial use around H2 2022. 2nm research and development is also well underway albeit in its early stages. So the basis of my question is what keeps pushing Moore's law forward when the large majority of the semiconductor industry believed 5nm to be an unavoidable wall of sorts just a few years ago?

    CPU 8 pin, Motherboard 10 pin, GPU 12 pin.

    Posted: 05 Nov 2020 02:10 PM PST

    I am confused, how come an 8Pin gives 235W , the new 10 pin from the ATX12VO standard gives 288W (continuous?) and the 12 pin gives 650W.

    The number of pins dont really add up to the wattage

    And why dont we (in the future) just use 2x 12 pin one for cpu+motherboard and one for gpu?

    Is it possible to develop a hybrid CPU that has extremely high single core performance on 1-2 cores and seperate group of highly efficient multi cores (8-16+ cores)?

    Posted: 05 Nov 2020 03:08 AM PST

    The idea is to run single threaded applications on the single thread optimized cores so that they run faster. Especially Main render thread of games.

    The multi-core optimized core group would support hyper threading or SMT and can run multithreaded programs, where these group of cores would be efficient and better perform on multi threaded programs.

    P.S: Im not knowledgeable in cpu architecture, it's just a thought I had, forgive me if this is dumb.
