Tempting to go for the 5800X3D to avoid a large upgrade and then to a larger upgrade when the AM5 platform is more stable. Not sure wether this is the best plan or to take the gamble and jump onboard AM5 on release with Zen4.

AMD confirms Ryzen 7 5800X3D launches this spring, Zen4 Raphael in 2H 2022

If you have Zen 2 or lower go for the 5800x-3d, and rest of the money spend on better gpu cuz that gives you biggest performance boost. If you have Zen 3 then you don't need to upgrade, just spend money on better gpu cuz as i said, gpu gives you biggest boost.
Depends what cpu you have now
if you have ryzen 1000 or 2000 it's worth it. If you have ryzen 3000, don't bother the gap between 3000 and 5000 is not massive so wait for next gen
Thanks, I have a 3900 but will hold off for Zen4 I think.
Some good deals on B550 and A520 boards recently.
first 3D V Cache benchmarks appear.
And interestingly, the benchmarks show that for applications that don't fill up the L3 cache, actually perform Worse on the new models. This makes sense, we know the new v cache chips run slower than the old ones, so if a piece of software is not utilizing the extra L3 cache available then all you have is a CPU with useless cache and slower clock speeds for your efforts.
When all the L3 cache is filled, overall memory latency is reduced below the old models and this benefits gaming - this is why some games will see a nice performance gain on the 5800x3d and some will see no difference or even a reduction in performance. To get any of the benefit of the new v cache requires the game/application to fill the L3 v cache, otherwise bandwidth and latency is no different to the old models and because the boost clocks are lower the game/application performs the same or slower.
This means reviews for the 5800x3d are going to be very interesting, because you will able to cherry picks benchmarks to show the 5800x3d running slower than the 5800x in some games and cherry pick benchmarks to show the 5800x3d running significantly faster than the 5800x in other games.

Not good, especially when the price may be considerably more than a 5800X thanks to the complicated manufacturing process.
AMD need Zen4 now - lets hope it remains on track for "2H 2022".
Server workloads are different as article said, we have yet to see game benchmark where 3d cache decreased performance. In AMD benchmarks worst results are tied with 12900k, and in games that use more cache they gained leadership. It is short term solution, enough to beat 12900k till Zen 4 comes and destroy RPL.
https://wccftech.com/amd-ryzen-5000...ower-stable-boost-clocks-better-ddr4-support/ Zen3d will be based on B2 stepping too so it will compensate lower clocks and power consumpion cuz of added 3d cache. Lisa Su also said in some interview that 3d cache could be disabled in BIOS, so with B2 stepping and in workloads that dont use much cache you could clock little more than regular Zen 3.
I'm sure AMDs cherry picked results are not going include games where it performs worse than the original Zen 3 but if this holds true then we may see a scenario like the HW unboxed 39 game benchmarks where it wins some and loses some so don't end up much faster than the vanilla Zen3 when averaged out.
Zen 3d will be enough for ADL, as i said it is short term solution, no need to create new architecture for ADL. Zen 4 will beat RPL, especially with their full ddr5 memory controller, and if that isn't enough they will have better 3d cache integration and yield by that time that will demolish Intel.
It's got to beat the 5800X first and given AMDs latest GPU can't even beat their previous one while being on a better node I certainly don't think beating ADL is a given especially now we are looking at performance regressions on some games.

Even AMD's own slides had it close to the 1200K. Are we just assuming that the 1200KS will slide into that tiny space on AMD's slides between the 1200K and the 5800X3D?
That shouldn't be a forgone conclusion with the limited data we have now.
I feel like people are picking a "side" and either overestimating or underestimating the performance of each of these parts based on the side they have chosen.
You are flip flopping betweeen believing early results and not depending on which suits you again., You said this just a page or 2 ago
Even the Linked review of Milan X states the performance difference on cosumer CPU's is likely to be different
we all know he is the greatest hypocrite here, he tells everyone how to behave/what to believe, but he does everything opposite of it.He Manipulates data, predicts the results the way he would like them to be etc. AMD poked him, and he can't cooldown a.k.a meltdown, classic fanboy symptom. Nowdays kids...
Doesn't have enough cores to beat ADL in vast majority of benchmarks. Would need a 5950X with 3d cache for that, which is not being released.

I don’t recall the test system amd used but if it’s something like base spec ddr5 on adl and 58003dx was trading blows, it’s gonna be a long day when put up against a tuned adl system.
I'm very curious as to the price. 5800X is already overpriced (vs ADL competition) at £400. 5800X3D needs to be £450 max for it to be a consideration IMO, though I can easily see it being closer to £600, considering the manufacturing complexity and price increases from TSMC.

5800X seems to be available online at around £330 today. I can see the 5600x down to £240 too. Both have been quite volatile over the last few weeks.
