It really gives me the heebie jeebies when people refer to Reddit (or any website) as an app, and in general demand that everything that used to be a simple website get turned into a data-hoovering Electron abomination.

New comment by pixelpoet in "85.3 GFlops: Optimizing FP32 Matrix Multiplication on a Single AMD Zen 3 Core"

pixelpoet — Mon, 20 Jul 2026 20:34:40 +0000

Zen3 isn't the best performing CPU today, though of course it'll never approach GPU level (which is pretty much ASIC level for matrix muls with special units). CPUs are getting dedicated "AI accelerators" too so it'd be interesting to compare per watt. The real limit is almost certainly memory bandwidth, not flops.

It would also be very interesting to see someone like Fabien Giesen / ryg do a maxed out AVX512 version for Zen5. His code's so fast it makes Intel 13900k's self destruct.

The next logical thought would be, maybe I want the thing I can't have (i.e. 100% of subscription used for Fable).

If they want to sell me 50% something I don't want then they get 0% sale and my money goes to their competitors. Simple as that, Anthropic.

Yes, yes, yes! I'm absolutely ready and waiting with dual Strix Halo machines here and really want something approaching Opus at home. Speed is secondary concern for now, that would absolutely change the world.

Qwen 3.6 27b 8b quant 16b kv cache is already pretty good on the Strix.

> Most of us would struggle to imagine a world in which U.S. soldiers, police officers, Border Patrol agents and elected leaders could be dragged before an international court, tried by judges from random countries across the globe, found guilty under international laws we neither consent to nor control, and then imprisoned thousands of miles from America.

Strange how they don't have any problems with abducting people from other nations (plenty of recent examples) to stand trial in the US under US laws, complete with meme'ing about being sent to alligator Alcatraz etc.

I disagree, it's both right in the title and the topic of the article. Weariness (fatigue), not wariness.

Yes, I'm aware of the word wary; now look up "weary". Wary as in "beware" is different from weary as in tired. I see this mistake all the time...

Since we're talking about fatigue: weary*

People who make such blanket statements only see things in black and white.

We're about to find out! Not to mention all the doctors who'll be getting sick from hordes of people with basic cold and flu piling up in their practices.

Man, Merz truly is a genius! You can tell he's had so much experience in normal jobs, truly understands the average worker's situation.

"Wireless-free" is such a ridiculous designation; you have a double negation and it still doesn't mean what you might expect (that it's wired).

I have a Framework Desktop as primary PC (great cooling, beautiful case with handle) and the Bosgame M5 dedicated for AI use.

I was also a bit wary about Bosgame but TBH they've been great and the machine is rock solid, if a little noisier than and not as pretty as the FD. You can just buy from them directly and be fine, best computer deal out there by a mile.

The Strix Halo mini PCs use the exact same chip, and have a much smaller footprint than any laptop. Have you seen the size of these machines? I can and have easily popped my daily driver computer into my very small backpack to attend a demoparty for example.

With the laptop you probably won't get silent operation at the peak 100-140w, i.e. you've now massively overpaid for lower performance.

I think people buying laptops for AI use are, sorry, just plain crazy. You overpay for the screen and keyboard and battery and whatever, plus you get much worse thermal performance because of basic physics (area vs volume). My Framework Desktop has a Noctua cooler which works really well.

[Tangent: all my life I've been downvoted into a smoking hole in the ground, particularly on reddit r/hardware, for questioning the wisdom of laptops for high performance computing, including gaming. Everyone insists they need the mobility, and then just leave it plugged in the whole time, absolutely refusing to admit it's about aesthetic preference.]

IIRC llama.cpp doesn't implement DSv4's compressed attention mechanism, and while it does use (credited) parts of llama.cpp, it's focused on this great model for now. Much of this is covered better in the repo's readme.
