Starfield is probably not representative for most future games, but DF found that on Intel both HT and E-cores caused performance degradation (12900K). On AMD however (3600) it scaled as its supposed to with more threads (SMT on). I think I'll be just fine with avoiding the whole b.L/heterogenous thing for the next generation too...
Starfield seems perform very badly with AMD CPUs, almost like they used crippling Intel compiler. So much for AMD sponsored title.

Would be interesting to see where exactly is the bottleneck for AMD systems.

Yep. So much for AMD sponsored title. Forget the performance woes for a while. Now this...

Starfield keeps frequently crashing on AMD CPUs (here & here). AMD should thoroughly test out their sponsored titles internally before it's released.

Why would AMD have to do the work FOR THE DEVELOPERS?
Note that there is precedent. Back during the golden age of twimtbp, when it seemed like nearly every game participated, the reason so many game devs signed up to the program wasn't payments of money (only major aaa titles got that), but access to nVidia QA, which was very competent and would test the game on all reasonably current nV cards using all reasonably modern cpus. For many smaller studios, this was too good of a deal to pass up.

(The unethical flipside was that nV often didn't actually report the bugs to the devs, and just added game-specific shader fixes to their drivers, leaving ati users to suffer from the bugs until ati replicated the fixes after launch.)

From the source you quote and presumably read:
However, there have also been a few cases of the game causing reboots on Intel machines as well. For one, the player who tipped us off about this issue was playing the game on an Core i7 13700k with a RTX 4090 GPU.
I've got an i7 13700k with a 4090 and have similar reboot crashes to what's being described. The first happened when Barrett gave me the watch, and the second is when I talk to a certain NPC in New Atlantis who asks me to get her a coffee from TerraBrew. That one seems to be reproducible. I also had another crash on the first planet Kreet when walking around, possibly from panning my view too quickly.

From the Reddit thread that the article quotes as source:


So the game consistently crashes on 13700K, 12700K and 8700K.

@SiliconFly did you do a minimal reading of either the press articles or the Reddit thread?

PcWorld & NeoWin articles say it clearly. Check'em out...
Yeah, NeoWin got tipped by someone who has these crashes on a 13700K.

It's right there, in the article. And both articles have one source of information, the reddit thread in which a number of people with Intel CPUs report having crashes as well.

So basically the game has issues on both AMD and Intel CPUs since the thread OP is on an AMD mobile system...

Has to be GPU drivers correct? If CPU is stable, user mode code won't crash CPU and the whole system.

Not really. Went thru the reddit. Looks like PCWorld & NeoWin have done a pretty thorough analysis. Majority of the cpus are predominantly Ryzen (with a few Intel cpus in the mix).

Speaking again on usefulness of higher single-thread performance, anyone has any idea what is the deal with Fandom/Wikia site? Just wanted to read something there, and its clearly heavy on CPU, as can hear the fans on the rad increasing their noise, as it loads, and it kinda stutters as well, like you wanted to scroll it down, but it has delay. This with tweaked 7950x to 5,8GHz on couple of best cores and 5,7 across the first CCD.

I am using Opera, so maybe its just some browser issue.

You know what I want to see? A benchmark face off between Granite Ridge and Stoney Ridge. Call it the "Rocky Ridge Race" or something.

Granite Ridge would probably be, what, 8X faster on multithreaded code?
Based on Geekbench numbers, a single GNR thread is about 4x faster than Stoney multi-core.

Starfield keeps frequently crashing on AMD CPUs (here & here). AMD should thoroughly test out their sponsored titles internally before it's released.

If they sponsor, it's in their best interest to make sure it just works!

Should we? Maybe we should inform PCWorld & NeoWin about this.

This is a Moderator response, so don't respond to it.

Most of the quoted posts were reported. And indeed upon evaluation; every one of these posts meets the definition of trolling in an AMD thread. The posts have nothing to do with Zen 5. They are all pot shots at AMD or follow ups to pot shots. This is your cease and desist order. Discuss Zen 5 or get out of the thread. Failure to comply will result in points that fill in spaces on your Ban hammer bingo cards.

EDIT: Discuss Zen 5 or stay out of the thread applies to everyone.

I don't have time to wade through this thread; seems to be a lot of off topic stuff recently.

Anyway, I was thinking about the CPUs used on MI300. They seem to be specialized to stack on top of the base die, but I don't know if they use SoIC or some micro-bump tech? The cpu doesn't really need SoIC levels of interconnect. It is a specialized cpu chiplet, although it is likely only the top metal layers. AMD does have a bit more ability to make specialized parts and the top metal layers would not need EUV, so mask are probably cheap.

I have to wonder if they would make use of this somewhere else though. I was thinking they might make use of them in mobile parts, but for Zen 4 based parts, that doesn't seem to be the case. The portion of the IO die where it is acceptable to stack on top may not be big enough. It probably cannot be stacked over GPU area due to thermal limitations. So are they really only making this special chiplet for MI300? Perhaps this will change with Zen 5. It would be nice to be able to get essentially 1/4 of an MI300 as a desktop or mobile part with up to 3 cpu chiplets. AMD seems to not be planning on using much stacking, other than v-cache, for mainstream parts. Has there been any rumors related to this?
