It was skeptical at first that it could be made and sold for less than $500, but I think my estimates on die costs being $250 was a little too pessimistic, doing rough math on my own with the 390mm die area and $18,000 N4 wafer price and the knowledge that being a lower tier part means potentially better wafer utilization if they're still making them the same as they did the last gen, I think circa $130 could be a more accurate estimate on die cost, and with this being meant to be midrange and considered a 7-tier part, I would expect it to be more expensive than but generally fall around 7700 XT pricing, so I could see them pice it anywhere from $450 to $500. I think $429 would be the thing that would make it an autobuy for me, $500 or more and I start considering waiting to see if UDNA will have something comparable, and if not, then get it cheap after all the discounts over time (or secondhand).

Of course, its only competition for me being $3,000 means they could price it $1,000 and I'd still be better off with it, but that would absolutely be a mistake I might still skip regardless out of indignation. I'm still happy with the RX 570 and want to make the way too much I spent on it worth it; the only reason I'm thinking of upgrading is for RT.

Firmware / Re: Messing with WOF Tables

Interesting, and that seems fair enough. Would you say there's a noticeable performance difference before and after, even if it's not enough to make it worthwhile? My case does have a bit more cooling capacity and internal volume so I have a little more headroom on heat, I'll still see how far undervolting gets me.

And yeah, the halved memory bandwidth does kind of hurt, but it seems like it's still on par with 7800X3D and such, so silver linings?

I bought the same CPU and I'm looking at some of the other tables, I wonder if one of the ones for 140 W could be used instead, or the voltage dropped a little and the nest and base frequency dropped a lot. I guess I'll test undervolts when I get the chance, but if I do go too far and don't give the CPU enough power, is there a way to bump it back up to regular voltages?

Yes, 9070 XT is... kind of stretching this nearly 10 year old CPU a little considering it's meant to be roughly 7900 XTX-tier, especially for people like me with paired CPUs, but it's also 2.0-slot and is guaranteed not to be $1,500 used or $3,000 new like the Radeon Pro W7800 is. Plus, it can always move on to the next generation when Raptor puts out the S1-based boards. I think it'll be my next move after the RX 570... I'd almost certainly need to get a stouter PSU than 550 W though, even that's cutting it close when I got a 231 (to be fair, it was a really good price).

Hopefully, RDNA 4 is similar enough to 3 that compatibility is pretty much already taken care of even before it's out, I know AMD has been doing some kernel work recently regarding it on AMD64.

Hopefully it gets picked up by someone else either in funding or manpower, it seemed really promising for the laptop space.

I can't see Raptor not wanting direct-attach RAM so they can try to maximize their sales of the new gen, I know I'd be less interested in S1 if I had to also buy the memory off them and I imagine most people would be; I kept hearing price as being the reason a lot of people didn't pick up Talos II or Blackbird I and that's with as much standard PC parts as they had. As much as I want to support them, I don't know if I want to support them enough to spend $900 on 32 GB of DDR5 because it's in a different form factor. I know SoSi is supposed to be a different company, but considering Raptor is probably their biggest partner and use case (if I was a company, I don't think I'd trust Solid Silicon based on their website alone), I don't imagine it's not a priority.

Nope, that seems to be where the April date comes from, though they did retweet something posted in May.

It seems SoSi's last LinkedIn post was only three months ago so I don't quite have alarm bells ringing just yet, but it would be nice to at least get like a photo of a prototype board or screenshot or something. We know they're working on it and they've released more information than that like it's compatible with at least one major heatsink format (I'm guessing SF2).

I'm looking at an AM5 air cooler, the Thermalright AXP90-X47. Is that a matter of air vs water cooled, or AM5 vs SF2?

You mentioned earlier that it could be 3D printable with the right plastic, would PA12 nylon be worth giving a shot? It seems it can be done for about $50 including vapor smoothing or tumbling, or $35 without. If I'm reading the spec sheets right it should have enough strength for the P9 mount and heat resistance up to ~90 C at that pressure, I'd mainly be wondering how it would fare statically.

Alright, good to know. What material should I get it done with?

I've read that already and didn't want to if I could avoid it, but finally went around to starting a trial of BricsCAD. Not even it can open it. I should also note apparently the commandline instantly crashes when I try opening it (so I can try to recover the file) so... I don't really know.
Also, the earlier file worked with all the aforementioned, it's just the repository ones that haven't.

I've been trying to even open the files on the github, and nothing seems to open them. FreeCAD, LibreCAD, Cura, ODA File Converter... I even tried handing them off to various print shops' quote pages and none of them could open them either. I don't think my copy is corrupt, I've redownloaded it a few times...

Oh, thanks for mentioning the 6800 directly. I'll probably only go with a 6600 or a 7700, but maybe I'll change my mind, so the confirmation is nice.

Hopefully, we see some optimizations soon.
