zeuskon US tech stocks see sharp falls over AI cost fears

More of these would be immensely helpful, right about now given the inference landscape.

zeuskon US tech stocks see sharp falls over AI cost fears

CXMT was hindered by various sanctions and lawsuits for the "allegedly" stolen IP. Intel can cleanly partner with Micron like they did for their Optane line (which btw can also offload a lot of the demand via CXL DIMMs).

They also don't have to match Micron, they just need to introduce sufficient marginal supply to a supply constrained market or use it to their advantage by making the memory for their own platforms by-passing the shortage everyone else has to contend with.

The upcoming cards for local inference use LPDDR (which is also not immune to the shortage) - but maybe it's time Intel gets back to its roots and produce some memory chips. CXL Optane would also shine as a KV cache store.

At-least Tesla didn't get sued and settle for $250M.

Exactly, are we forgetting the apple airpower? or apple intelligence?

btw, slicers turn the STL into g-code for the printer before you hit print. STL is just easier to work with for the transformations that need to happen within slicer software.

zeuskon Samsung's Processing-in-Memory (PIM)

Hey, just don't store your pagetables in PIM capable sections :)

zeuskon Samsung's Processing-in-Memory (PIM)

That really doesn't make sense because your system is already using memory that needs to be physically contiguous but mapped virtually. Also, would you say pinned memory is not part of the virtual memory system??

You're only restricted by the fragmentation of the system memory which is an issue yes, but it's dealt with in other ways.

zeuskon Samsung's Processing-in-Memory (PIM)

why would it? the parent OS can already handle physically contiguous allocations so these should be no different (with the exception that a separate interface can be used to do compute over these buffers/pages).

zeuskon New Mac Studio with M5 Max and M5 Ultra

PS4 is as close as it gets to the colloquial computer; it's a AMD APU running BSD with homebrew linux builds available.

And if not, would you consider a raspberry pi a computer? or your iphone a computer?

zeuskon The USB Situation

> copper can barely support 10G and is terribly power hungry when it does that.

AFAIK, thunderbolt cables are also copper - so what trickery do they use for supporting USB4-80? i believe both connectors use differential pair wires for signalling.

zeuskon Roblox shares plummet 18% as child safety measures weigh on bookings

Half life alyx and their push for openVR has made a big impact in that part of the gaming world.

But yeah, their games are just as filled with lootbox, crates, skin garbage as other low effort money grabs; saving grace being its all cosmetics only (and they’re private about their financials).

SR-IOV is just that? and is well supported by both Windows and Linux.

zeuskon SIMD programming in pure Rust

They’re used by the internal register renamer/allocator so if it sees you’re storing the results to memory then reusing the named register for a new result - it will allocate a new physical register so your instruction doesn’t stall for the previous write to go through.

zeuskon The 512KB Club

Yes, but parent comment definitely implied they weren't talking about people running on the latest and best out there. Even the middle-grade smartphones today are leaps and bounds better than the atom from 2010.

> And yet, if I go to Youtube or just about any other modern site, it takes literally a minute to load and render, none of the UI elements are responsive, and the site is unusable for playing videos. Why? I'm not asking for anything the hardware isn't capable of doing.

but the website and web renderer are definitely not optimized for a netbook from 2010 - even modern smartphones are better at rendering pages and video than your atom (or even 8350u) computers.
