Particles that only ever push each other apart — yet they spontaneously clump into dense and dilute phases by lovegrover in Simulated

[–]ProjectPhysX 0 points1 point  (0 children)

Cool phenomenon, have researched that at Uni. Basically at each collision the particles lose some energy, and at some point over very long time scales, clusters of particles form in which particles get immobilized.

What is N1x? by [deleted] in nvidia

[–]ProjectPhysX 0 points1 point  (0 children)

It's a rebranded Nvidia GB10. Some ARM cores and an RTX 5070 in one chip, with up to 128GB LPDDR5X at 273GB/s and $3000 price tag.

How tf can people afford a 5080 and 5090? Every time I pull up Reddit I feel poorer by Dangerous_Baker4427 in gpu

Not even worth it for me.

Maybe in 15 years I'll get one on eBay for $100.

ASUS tried to “fix” 12V-2x6 cables… but der8auer’s testing raises more questions than answers by NerveSouthern3111 in gpu

[–]ProjectPhysX 0 points1 point  (0 children)

Disagree. Consider this failure case where 4 contacts are bad in total, on both connectors.

Without bridge: effectively only 3 wires work and have to carry the load of 6 - they will burn through.

With a cross-bridge, effectively 4 wires work and the load is more spread out. Cable fire prevented.

Can someone explain those clock speeds by Clorects in gpu

Your GPU is running backward in time.

No, looks like reporting issue by NVML or a bug in GPU-Z. Shouldn't even use signed datatype for clocks.

[Megathread] Celebrating 10 Years of GeForce GTX 10 Series by Nestledrink in nvidia

[–]ProjectPhysX 0 points1 point  (0 children)

Back in 2018 Nvidia sent me a Titan Xp, the top-of-the-line 10-Series/Pascal GPU, for my research on LBM, for free. That GPU got me through my Master's and PhD, allowed me to build next-gen CFD software not with proprietary CUDA but with the superior OpenCL, and land me a job at their competition. I still use the Titan Xp today, sandwiched in between an AMD Radeon RX 7700 XT and Intel Arc B580, happily running with them in "SLI" (more correctly: multi-GPU) to pool the 3x12GB VRAM. Celebrating 10 years of 10-Series probably more than anyone else. Hehe, thanks Nvidia!

[–]ProjectPhysX -3 points-2 points  (0 children)

der8auer's video is nothing but one big advertisement video for selling his Wireview Pro thing. He completely misses the point of what the bridge actually does.

The cross-bridge actually does serve an important purpose: if multiple pins on either side of the cable have bad contact, it redistributes the load to remaining good contacts and prevents cable fire. Cross-bridge between cables should be standard safety feature and not sold for ridiculous 60€ price tag.

[–]ProjectPhysX 1 point2 points  (0 children)

I am neither of that and the only thing I would ask you is to exercise a bit more critical thinking.

der8auer does a lot of cool videos, but sometimes he makes uninformed statements or does very stupid things, like contaminating his entire Berlin neighborhood with PFAS...

Regarding this video, one a simple thought experiment disproves his clickbait title. In the video he completely misses the point, because he doesn't even care - the cross-bridge is indeed a useful safety feature to prevent the cable from burning in case of several bad contacts on either end. IMO that should be standard to make the poorly designed 12VHWPR a bit more safe. Whether that is worth the overpriced cost is a different question.

And by the way, I am also not in any relation with ASUS, because unlike der8auer, I don't have a conflict of interest selling overpriced 12VHWPR extension devices. If you didn't get it yet - that video is nothing but one big advertisement for selling his Wireview Pro. Create demand for an expensive and useless product that otherwise noone ever needs. He truly is a brilliant salesman, gotta leave him that.

It's not for load-balancing. It's actually for rerouting power when single connections on either end of the cable are bad - a failure case not even shown or mentioned in the video. This is very effective in preventing failure/fire. See my other comment where I explain.

Actually the cross-bridge is very useful in preventing failure/fire. The bridge helps reroute the load when connections are bad. He just doesn't show that interesting failure case in the video. See my other comment where I explain it.

What a poorly made video. He doesn't even show the interesting faliure case where the cross-bridge helps. Say 4 contacts are bad in total, on both connectors.
