  • I can guarantee you’ll get more bang for your buck going with Nvidia just due to the fact that so much compute software requires cuda (blender, machine learning, any sort of engineering simulation software). Nvidia drivers are just less of a pain to deal with as a developer, since they’re less strict on error handling and syntax.

    You can get a 3050 on amazon for like $150 now, which is more than enough for most games.

    Plus DLSS is still miles ahead of FSR in terms of quality and efficiency.






  • Based on this pin configuration, there’s only two dedicated power pins, which isn’t very good for large wattages. The rest are twinax signal pairs separated by ground to reduce crosstalk.

    Usually when connectors are designed for power delivery, they’ll use bigger contacts to reduce the contact resistance (signal contacts tend to be small so you can fit more of them in the same space). I’m guessing the original DP connector form factor wasn’t made with such high power in mind, so it would make a lot of sense to use the spare signal pins for power delivery in this case. Running too much power through too few small pins can damage the contacts, by either by instant-welding the contact surfaces or by overheating the connector (see NVIDIA GPUs) ((also high voltages can cause arcing, which even in the best case will seriously degrade any connector)).

    Take all of this with a huge grain of salt cause I just learned this stuff like a month ago, and my department has nothing to do with any of it. Just though someone might find it interesting.






  • One of their older color products is a traditional B/W screen with an RGB filter over the top. The problem with this is the filter tends to make everything way darker and muted than it should be.

    They are also working on newer ACeP screens that use multiple colored dye and pigment particles in the same capsule. By swapping the colors around with specific electric waveforms, they can control what the color looks like from the front. The downside is that this color swapping often takes several seconds to produce the correct color ((also the color gamut has a lot of holes))

    The article starts by doing the “quantum” thing that really irks me, where they use confusing terminology to make it sound like “FTL communication” without actually saying it. This is garbage that doesn’t actually matter to the article.

    Basically, they found a way to send quantum entangled photons (which exist in a very delicate unobserved state) through existing fiber optic infrastructure without interfering with the standard internet information already travelling through the fiber. A lot of the difficulty with this is due to signal noise that needs to be filtered out. This will be useful communicating quantum measurements over long distances.
