  1. High DPI: It's one of those things everyone is trying to get right. Perhaps offer two versions of the interface, one that fits nicely into a 4K screen :)

    Screenshot: Awesome, thanks

    Time left/time taken: Also, thanks!

    CLI: I ask for this in the sense that say I'm testing a bunch of CPUs at stock for a review, and I want to automate the process but still have the results applicable for comparison. So you can disable HWBot submissions with CLI mode, but just so I could get a score out without having to babysit my benchmarking routine.

    8K: Do it. Do it. Do it. :D If you can find an appropriate video to add to the download (1GB?). You'll be surprised and how the x265 algorithm deals with small frames and big frames, where L3 cache / eDRAM matters and whether it can exploit IPC. That's when the step ups to larger L3/core might be more significant.

     

    MultiCoreWare: Like I said, I only discussed it as part of an IDF meeting and they hadn't given it much thought at that point so you wouldn't have seen any basic benchmark online from them yet. But we did discuss and they were keen - they'd work with anyone who is/was willing to develop one and spread it out.

  2. My input:

     

    Doesn't display properly on HiDPI displays - allow for 150% / 200% scaling.

    The submit 'take a screenshot' takes a long time when running high resolution displays. If you're going to implement a result submission that relies on a checksum, I'd suggested limiting the screenshot to an ALT+PRTSCN application that just captures the benchmark window.

    Show the time taken to process the benchmark at the end

    Show the estimated time to complete during the benchmark

    Allow a command line interface to run the benchmark which screenshots the result, saves the HWBOT file, and quits out automatically. That way someone could script up 50 runs and just choose to submit the best.

    Automatically generate a result text file with a verbose output, or in the log include the benchmark result.

    Include 8K. For LOLz.

     

     

    Out of interest, have you spoken at all to MultiCoreWare in preparing this benchmark? They develop the x265 algorithm which is meant to be the toughest and most efficient in the business. I had a good long chat with their VP of product management about our own x265 encoding tests at AnandTech, relating to overclocked stability while transcoding, last week at IDF. We even discussed the potential of an open benchmark, like x264 HD 5.0 and the like. Looks like you're already ahead here, albeit with Java in tow. But it might be interesting if you did a cross collaboration on this. I can make intros where necessary, hit me up.

  3. You might be confusing the science here.

     

    Here is the phase diagram of pure water:

    In order to get below 0C with pure, regular liquid water, you would need atmospheric pressure around 100 MPa (or 1000 atmospheres).

     

    Supercooling is a process that allows liquid water to be below zero, but any presence of turbulence (i.e. a pump or a heat source) or nucleation site (water cooling tubes) will cause the liquid water to form water ice.

    http://en.wikipedia.org/wiki/Supercooling

     

    Using a commercial walk-in fridge to increase the localised air pressure will have minimal effect. The act of opening the door creates the slush - movement creating nucleation sites.

     

    Of course when you start using blends (water/ethanol, antifreeze), then the freezing point can be lower than 0C due to the prevalence of hydrogen bonding in the mixture. Add in a multi-alcohol chained compound into water and away you go. But as we have mentioned, introducing a blend means you should be moving on up. Is there a way to check if someone has used a blend? No, but therein lies a small amount of trust within the community (just like everyone trusts you won't murder someone in the street).

  4. This topic has been discussed AT LENGTH before on the forum (I'm sure even I've told you Lewis!).

     

    Using a water chiller with WATER: OK for Enthusiast League

    Using a water chiller with a blend: Not OK, move on up.

     

    It's also the only way regular enthusiast users can compete with sub-zero climates of mountain benchers.

     

    I have a Hailea chiller, just need to get the rest of the loop. These chillers are built to have 3C to 20C selectable - the only way to go lower is by modding the thing.

  5. I'll be there. G.Skill and Galaxy/HKEPC will both probably be doing something on their booths, no?

     

    Yes, everyone the Monday of Computex Week is a national holiday. So arriving on that day might not be fun. Get there the day before, recover from lag, and enjoy the Dragon Boat festival.

     

    DTF would be awesome, but if you go with more than 4 people at a time good luck. With three it took 45 minutes to get a table.
