Well we know now how they will bridge the long wait to Zen4 on AM5 Q4 2022.
Production start for V-cache is end this year so too early for Zen4 so this is certainly coming to AM4.
+15% Lisa said is "like an entire architectural generation"

I currently own a Ryzen 5800x and was wondering if a Ryzen 5800X3D is the best CPU for Flight Simulator and X-Plane 11 right now? Does the greater L3 cache size still bring a huge benefit in these two games despite the lower clock speed or are these two games mainly reliant on clock speeds and IPC with L3 cache size having barely any effect?

So Far I cant seem to find anyone testing Flight Simulator

I don't think anyone takes them too seriously these days. Even r/Intel has banned them from their subreddit for being so obviously biased when they intentionally changed the way the calculated their benchmark scores to add more weight to single core performance because AMD had such a massive advantage in terms of core count at the time. I was hoping that they had a blurb for the KS just to see the comparison, but they don't have any write-up for it yet.

I'm pretty sure "God's gift to the world" would appear in such a writeup.

AMD's radical new design approach with Zen and their ability to iterate and refine it so well caught Intel completely off guard. The process issues they had also hindered their ability to compete, but I'm not sure it ultimately would have been able to save them.

Even now that they've made some architectural shifts that will allow them to compete better, they're still having a difficult time of it. Even without v-cache, AMD has still remained competitive with Intel's latest and greatest and there are still a few benchmarks that Intel can't win, even when pushing the power to absurd levels.

But the inclusion of v-cache opens up even more possibilities for AMD and it's built in the same modular fashion that allows them to apply is selectively so that they can use a very limited number of dies to assail Intel's entire product stack and even control areas that Intel has had to essentially abandon.

I went back to check the write up for the 11900K since that would have been in a similar position and it's a gold mine. They legitimately spend more of their summary complaining about AMD or other reviewers than they do talking about the 11900K.

It's like Lisa Su ran over their dog or something.

While the golden cove core is strong, the way Intel has configured it, it takes a lot of power and produces too much heat.

Very much this. I think the most interesting of the 12th gen lineup are actually the T versions. Where the turbo is limited to 69-74W until you get to the 12700T which is merely 99W. That 74W power limit is very close to the 76W PPT of my new 5700X.

Those are more like it for efficiency. Nobody seems like taking them* out for a spin though, but I think a comparison to Zen3 would be interesting.

*You can even simulate one on a standard non-T. Just set PL1/PL2 and there won't be any difference.

Do not speak that name! He may yet appear!

That aside

I don't see AMD's launch of the 5800X3D as a reaction to Alder Lake. If anything, AMD has demonstrated that they just don't care about Alder Lake one bit. They probably could have launched Vermeer-X months ago, but chose not to (okay they may have been working on that cache optimizer doohickey I dunno whatever). If Alder Lake "scared" them then 5800X3D would have been paper launched before February. And they only launched one SKU! Where is the 5900X3D from the original demo? I don't see it. Much less a 5950X3D. Competing with Alder Lake directly and immediately just wasn't worth AMD's time.

Think they just ditched the idea after ADL officially launched. There is just no need for a 5900X3D or even 5950X3D because ADL is no threat for AMDs MT and efficiency leadership. The 5950X is still the best CPU regarding that. And for gaming the 5800X3D is good enough to compete while being crazy efficient against the competetion.

Kind of my point. AMD realized they didn't need either SKU as much as they needed more Milan-X.
 
I'm more inclined to think that a 5900X3D or 5950X3D with a larger V-cache may pose a threat to Zen 4 since that won't have the benefit of V-cache for some time to come. Cache is king if most of the hot data resides in the cache. I doubt Zen 4 with even DDR5-8888 would be able to counter the benefit of a huge cache.

Maybe, but there seems to be a lot of workloads that does not benefit from the extra cache and lower clocks, and if zen4 both has better IPC and 5Ghz all core boost, then it should not have any problems beating a hypothetical 5950X3D. I think AMD has been very open about where extra cache is beneficial: Large scale computing and various professional work and gaming. But they have from the start also showed that some games and and some software actually saw a slight regression in performance, due to lower clocks. So as a potential customer I find it very transparent and quite easy to see if it it is a product that would suit my needs.

41% Faster Than 5800X and 21% Faster than 12900KS is a Generational+ Upgrade kind of performance boost

If I would of know about the robust PCIe slot setup with this Godlike board before I bought my Xtreme I wouldn't be posting these sentiments
