For many LLM load, it seems ROCm is slower than vulkan. What’s the point?

he won't. if anything, openai is falling behind recently. the trend won't change easily. it is like the old time Netscape.

only works if the users are evenly distributed around the globe (which is likely more of less the case). if the user concentrates in on century, the token rate will be terrible.

i hope someone do a 100b 1-bit parameter model. that should fit into most 16GB graphics cards. local AI democratized.

i am guessing, without any proof, that, when one breaker fails the server lose it all, or loose two GPUs, depending on whether one connected to the cpu side failed.

9070XT provide roughly same inference performance at double the power, half the cost, as RTX PRO 4500. So this one is optimized for total BOM cost.

they could had gone with the Max-Q version RTX PRO 6000 and only require 120V circuit. 10% performance hit, but half the power.

fundamentally, looks like they are shipping consumer off-the-shelf hardwares in a custom box.

ycui1986 — Fri, 20 Mar 2026 05:11:55 +0000

for all past years, I have been told wayland is the future. but the decade long dragged out rolling out did not made much sense to me. neither did I investigate why. until today, I found out how difficult to force a 1920x1200 resolution over remote desktop. it is plain feature degradation.

people ask why do you need it. I have a 3440x1440 physical monitor on the server, I need to remove login with a 1920x1200 laptop. I want full screen at laptop's native resolution. Windows can do this decade ago.

the reality is no where to get the fuel. hydrogen stations are shutting down not building up.

it is bizarre that a notepad app can have remote code execution. how much unnecessary function did MS add to get to this point?

If what Waymo wrote is true, this sounds more like kids fault or guardian’s.

everyone uses cellphone that transmit on the same frequency. they don't seem to cause interference. once enough lidar enters real word use. there will be regulation to make them work with each other.

used NI-GPIB on USB cost $100 on ebay. You don’t need $1000.

very impressive. better than anything on the market either NI or Keysight.

from the picture, the compressor and generator located inside the dome. the dome is filled with CO2. maintenance people have to carry oxygen tank, or they die.

i think it had something to do with CO2 can be made into supercritical state relatively easily, not for nitrogen or other common gases.

no mentioning of storage overhead? how much energy being wasted for each charging and discharging cycle?

cheap microcontrollers use RC oscillators. If they only drift a few seconds a day, that would be an achievement by itself.

RC oscillator is poor enough that early days USB communication would fail if running on RC clock.
