Community rules (click to expand)

1. Follow the site-wide rules

2. Be civil
  • Understand the difference between a joke and an insult.
  • Do not harrass or attack members of the community for any reason.
  • Leave remarks of "peasantry" to the PCMR community. If you dislike an OS/service/application, attack the thing you dislike, not the individuals who use it. Some people may not have a choice.
  • Bigotry will not be tolerated.
  • These rules are somewhat loosened when the subject is a public figure. Still, do not attack their person or incite harrassment.
    • 3. Post Linux-related content
  • Including Unix and BSD.
  • Non-Linux content is acceptable as long as it makes a reference to Linux. For example, the poorly made mockery of sudo in Windows.
  • No porn. Even if you watch it on a Linux machine.
    • 4. No recent reposts
  • Everybody uses Arch btw, can't quit Vim, and wants to interject for a moment. You can stop now.

    • Please report posts and comments that break these rules!

    iGPUs are pretty useless for the most part.

    1. Shared memory. Regular DDR is high latency high throuput. GDDR is low latency low throuput. Not only you're sharing memory with other apps, you're also penalising yourself in terms of performance.
    2. iGPUs are very slow at computation. Yes, they have codecs built-in, but if you want to run custom math they are not much better than running it on CPU.
    3. CUDA is not available. OpenCL is, but some apps are locked to CUDA.
    4. Old GTX 1080 is 5.5 times faster than brand new Iris Xe at computation. RTX 4080 is like 3x times faster than GTX 1080. That's an order of magnitude difference between modern GPU and modern iGPU.

    That makes sense. Thanks.
