looks like 5800x is indeed the only zen3 cpu getting 3d cache   zen4 2nd half of 2022

man, i don't know why i expected their 3d cache cpu's to have more cores than this, but this is not the hedge against intel's push i thought it'd be not sure whether i'll do an am4 upgrade of my cpu if that's it

I guess supply constraints so do the CPU that has one chiplet. 5900X or 5950X would require two chiplets to be stacked with the extra cache, and 5600X isn't premium enough. Guess it's a mind-share halo product rather than a mass seller. Disappointing lack of info about Zen4, other than it can boost to 5GHz all core.

The comparisons to the 12900k are making me think that the 3d cache chips will be pricey.

Imagine going back to 2018 and saying AMD has the fastest gaming CPU but it sacrifices cores and application performance compared to similarly priced Intel options. Topsy turvy.

do they usually announce cpu prices at these things? does the lack of a 5800x3d price tag imply it's not gonna be pretty?

I might just pick up the 5950x to upgrade from my 2700x. This machine will eventually become a server, anyway.

I'll wait to see how the pricing shakes out over time, but a 5800X3D RAGEMODE does seem like it would be a decent last AM4 upgrade over my 3600X.

Overall the announcement is a damp squib (for desktop anyway, I didn't listen to any of the laptop stuff). Not much we didn't already know. I was expecting at least a firm date for the 3D cache chips.

I finally got a hold of a 5900x to upgrade from a 3900xt. I sort of didn't buy memory quite right and it's 4000mhz. After a bunch of tries in increments leading up to it I got it to boot at 4000mhz and 2000 fclk. Everything has tested OK for my uses so far, though I need to do more. Sometimes, though, when booting up it halts and clocks the memory and IF back down. Is this likely just the ram or motherboard being finicky (It's the Asus TUF x570-Plus, which I know is on the budget side of things). I have it all set to the XMP profile for memory at 1.4v and no changes to CPU stuff other than the 2000 fclk. A couple resets later it'll boot OK or I put it at 1966fclk/3933mhz, boot into Windows, reset, put it back to 2000 and then it'll work without issue after many reboots and days. Or maybe I'm doing all of this wrong. Now I need to try to sell the 3900xt I was using this year while trying to get a 59xx series, so hopefully there's still an easy market for them.

Been waiting for someone not apple to make a good igpu for awhile.

I don't think you can avoid having the board retrain the memory if it fails diagnostics on boot.

Going to go pick it up today.

repiv posted:some AI company is already doing chips that fill an entire wafer yeah they basically just have a mesh topology (like the mesh interconnect Intel uses in Skylake-X and Skylake-SP) and they just turn off the cells with defects and route around them. at a smaller scale, I actually met a guy at an IEEE conference who was working on the software for the Epiphany co-processors used in the Parallela SBCs. Same kinda thing, it's basically a square grid of RISC cores that can pass messages along an x- or y-direction. Anyway basically the Ephiphany-III was a 4x4 grid which yielded well enough but the Epiphany-IV was 8x8 and the Epiphany-V was a 32x32 grid and at that point they couldn't get full yields, so they pursued the same kind of solution where a couple cores would be turned off and you'd have to route around them. Also they could then stack the chips themselves into grids to scale even further. Similar to Intel, the IO blocks were on the edges of the mesh. It kinda sounded like the applications were some of the same kinds of things that DSPs do, heavy numeric crunching, but I assume there were some advantages of doing that vs just a DSP. Obviously still needs the program to be seriously contorted (MPI, and you need to route the program data processing flow along that grid, or at least pass the messages) to make it work, but kinda neat. https://arxiv.org/pdf/1610.01832.pdf https://www.adapteva.com/docs/epiphany_arch_ref.pdf Paul MaudDib fucked around with this message at 19:52 on Jan 5, 2022 |

Dropping in with an anecdote: I tried to flash my ASRock Rack X470D4U BMC this week and it completely poo poo the bed. I assumed I was well out of warranty but submitted a ticket anyway, and after a bit of diagnostics they just told me tonight that they're sending me a new preflashed BMC chip. Super happy with the support and though I'm glad this means I don't have to buy a whole new mobo right now, I'll definitely look at ASRock Rack products whenever I upgrade this machine.

Too bad little was said about Zen4. I'd like to hear more about PCIe lane availability. I really doubt that the added 300 pins are just power delivery and some pins for video.
