Suffering from excitritis as well. Well, more than regular. Still hanging on to a (r)aging Intel 2600k though. So perhaps I could wait just a little, little bit until the reviews come out. Done that for over 10 years now 😕 or is it 11 or 12 😀

Well, you're in for a treat. Going from an i7 920 x58 to the 3800x and x570 was an amazing upgrade! I just built a new gaming rig a couple weeks ago due to wife in need of a new pc. The timing couldn't have been worse. I was looking at the 13700's and 13900's and they do perform quite well. But as a 1440p gamer also in need of a gpu upgrade I went with the AM4 platform using the 5800x3d. Wish I had the budget for the AM5 but the pricing was just out of the budget. It's all good, my 5 year old will get the 5800x3d rig in a few years. I've had Intel and AMD gaming rigs over the years. The 3800x has not dissappointed.

There are very few work applications that benefit from all that extra cache. The only people that should care about these 3DV cache parts are gamers.

Oddly enough, it's almost the opposite on Linux. In any case, your underlying point remains valid: these CPUs are only worth getting if they improve the workload you put them under. While it'd be nice to have the same OC capability, I'm guessing most people would quickly find out that they're not going to benefit much from doing so when the chip keeps thermal throttling.

i think its worth mentioning that the boost limits of the 7950x3d 7900x3d are still 5.7/5.6ghz doubt that you'd ever hit or exceed that with a boost override on the 3dvcached die. only product that seems to be badly nerfed by the lack of overclocking is the 7800x3d. though if your board has eclk support it wont stop you like the locked multi on the 5800x3d did.

Well only the CCD without 3D cache overclocks that high out of the box. But you are right still. edit: I'm wondering... does AMD allow you to overclock the CCD with 3Dcache and the CCD without it seperately? 😱

Zen CPUs can be overclocked with deferent values per core. So it's possible to do that, if AMD wants to.

you might already be able to do that, as you can set per ccx ratios, If you set one to auto and one to a fixed ratio, I would assume that you get normal boost on one and fixed frequency on the other, I've never seen anyone actually do that though, so I can't confirm it.

Thanks, I didn't know that, haven't had an AMD CPU in decades ^^

The answer could be more simple... they might just want to pull an Intel and artificially gate performance. I certainly believe they did that with the 5800X3D. I have one and it runs cool, with the L3 running far cooler than the cores. IIRC the L3 runs no higher than 52C while the cores are stressed even to 80C+. I use PBO2 tuner to undervolt it to get a pseudo overclock, and it does make a significant difference under 100% load. The 5800X3D, at least my sample, appears to have a ton of headroom with no good reason that I can find for it to be locked down.

What is there to gate? Those will be amds top gaming CPUs and if you do not care about the extra fps on 1080p vs the non 3d ones you buy the cheaper non 3d ones! They would have been pulling a total Intel if they where to lock the non k CPUs!

To gate for? Their own next generation? The 5800X3D is part of the reason (with the main one being stupid prices) why Zen 4 was selling really poorly to start.

Yup, and AMD knew it when they released the 5800x3d. The AM4 socket had a 5 year lifetime so you have a large base of customers at hand for the 5800x3d. Once again, I'm surprised AMD released an x3d cpu at all for the AM4 socket. That shows us that AMD does understand the enthusiast market even though they knew it would cut into the AM5 sales. So rather than piss off the enthusiast base they give those of us on a budget the 5800x3d. AMD as a company doesn't survive on the enthusiast market, we are another class of customer and a small base in comparison to the large quantity of sales to desktop producers etc. But to your other point, the AM5 prices are quite high. I wanted to go AM5 but budget said no freakin way! I'll give AMD credit for giving the AM4 gamers the 5800x3d.

Well ... There must be something they afraid some users might do ... Since those will be their best CPUs until Ryzen 8xxx 3d comes out the have no other reason to lock em up no ?

Probably they are afraid that some people might fry their CPUs overclocking them while they are still under warranty... Sometimes is better to play safe than to be sorry.

Can you share your PBO2 tuner settings? I recently bought myself the 5800X3D as well.

not accurate 5800X3D IS a triumph, but sales have more to do with the economy plus Intel cutting their margins on AL & RL to limit AMD's market share. AMD has been playing in Intel's most profitable sector (client computing group) and in their head for the last five years. Intel's gamesmanship has a direct effect on sales and availability worldwide as they have a far larger number of sales channels. this is not a guess Q3 2022 numbers show the reality that Intel is taking "a dive" to increase sales numbers and to make up for the 13% of business lost to Apple's (M1/M2 replacing 11/12 gen cpus from CCG) increase in PC shipments.

we have different definitions of "enthusiast base". every Ryzen processor ever sold separately is an "enthusiast" sale. AMD does survive on the enthusiast market - it's everywhere else they have difficulties. i'm not being argumentative, there are real differences in how th PC market shakes out. as many know Intel rules the marketplace regardless of qualitative differences. as such i will roll with Intel's definition where all CPUs not bound for OEM machines/laptops/ultralight are part of their Client Computing Group - which is in a huge tussle with AMD. the situation is completely reversed for AMD as they have a tiny share of the OEM/laptop/ultralight business.

5800x3D here, no "unusual" issues infact none anyway overclocking the 3d chips is not needed at all cause your only going to buy if your a gamer under volting with curve optimizer/PBO2 however is an absolute must! mine is set to -30 all core and that results in an all core boost of 4.45ghz sustained at 1.163v max tdie temp was 77c before UV it was 84c under corsair h100i pro 240mm less voltage = less heat, on my chip that also means higher boosts

Was a bit tongue in cheek fun poking at the existing usb issues on zen 3 still affecting some cpu+mobo combos, i hope to heck zen 4 doesn't have them.

Expensivasts? Some could say, masochists? People who like to experiment with new platforms that are not really tweaked and optimised yet? I don't know... I think people should have two mains to go for Ryzen: If it performs well enough for a reasonable price and you don't want to suffer from monthly mitigations (like it used to be the case with Intel for some time) That said, and now I'm probably going to get stoned, but not in the good way: I have the feeling that for most people, it does not matter what platform they use.
