I'm salty that they waste so much die area on irrelevant crap like ray tracing cores, tensor cores, and graphics stuff. Just give me a good massively parallel general-purpose SIMT chip dammit.

"tensor cores" are literally just special matrix instructions in the SM, they don't even take up that much die space, you've been tricked by gamer marketing

the way i understood it rtx is mostly a marketing play to get gamers to buy gpus with a bunch of tensor cores (designed with tensor cores originally for the numerics-on-servers market). the idea being that "rt cores" are a tiny extension on the existing tensor cores, giving them easy economies of scale on the single design. e: and i guess tensor cores are indeed a lumping-together of cuda cores. 8 cuda cores make a tensor core (presumably with some little added logic block), 8 tensor cores make an rt core (presumably with some little added logic block).

the relationship between SMs / CUDA cores depends on who you ask (sometimes they group them multiple SMs with a texture unit and call that the CUDA core, sometimes they mean SM = CUDA core, whatever marketing finds convenient), but RT cores have a real hardware unit that are 2:1 with the SM (I think? depends on the arch / revision), tensor cores are effectively some extra matrix math the gamer premise for "tensor cores" is DLSS the gamer premise for "rt cores" is ??? i mean, they tried quake 2 rtx, it was... kinda ok? they're working on more rtx remasters too

none of the rtx cards are fast enough to do all the rt effects at the same time so every game that comes out now uses rt for one thing. it definitely improves things tho so it will be cool in a few card generations when its viable.

Athas posted:Pretty funny that RMS of all people had to step in and be the adult, in particular giving social advice on how to cater to ESRs ego. i was gonna post about that if you didn’t, it was astonishing seeing rms of all people coming in and talking esr off the ledge after esr tried to claim the right to prevent the de facto maintainer, thomas dickey, from making new releases if you follow the story to the end, the solution was to bring in a mutually agreed upon neutral new guy as the new maintainer and get the main copyright owners to assign to the fsf so that a new license (not the gpl!!!) could be applied, clarifying problems with the original. but then the new guy hosed off without doing much other than blessing a single release and dickey resumed maintainership

Soricidus posted:you probably can’t escape the tensor cores anymore but lol if you’re doing work on gamer hardware. get a tesla card already Gamer hardware is all I can afford. I do the wrong kind of ML (the PL kind), so I don't have infinite money. I tried programming against one of the original Xeon Phi's but I can't say I liked it much. It was batshit insane that it ran its own Linux instance that you had to SSH into. I hear they fixed that later, but I just can't get over the feeling that they're really pushing x86 beyond what it's meant for. No matter how much they widen those vector registers, it still ain't gonna provide GPU-style latency hiding. I really like the NVIDIA-style GPU architecture and also its low-level programming model. The rules are strict but predictable, while x86 rules are much more flexible, but the performance pitfalls less obvious. I much prefer the former (esp. since my job is writing compilers, not so much writing GPU code by hand). That's also why I don't care so much for specialised things like tensor and RT cores, since they are tricky to exploit from a high-level language. I know that's probably where we have to go anyway for physical reasons, but I much prefer general-purpose computing. The tensor cores are at least useful for doing silly half-precision small matrix operations. The RT cores... aren't they about accelerating BVH lookups somehow? Can't see how that's generally useful. Did NVIDIA give much more detail than Make Quake 2 Pretty Lights?

I've been using silver blue on my new laptop, which is red hat's new think that distributes the is as a read only system image with various container things used to install additional software There are rough edges of course but it is surprisingly usable day to day. Very fast system updates too.
