This reminded me of the thick IHS on the 7000's but maybe its the weay to go in the futur. Where the IHS *is* the heatsink.

This i9 is passively cooled using a single block of copper, and results are surprisingly good (35°C idle, 80°C max) https://reddit.com/r/hardwaregore/comments/10mrrp5/passive_cooling_an_i9_with_a_8lb_block_of_copper/

Kind of annoying that they are holding the 7800X3D back, but I will likely wait for it. For a gaming system more than 8 cores rarely matters, and I already have other 16 core systems for productivity tasks. I feel a single CCD is also more reliable for gaming. Although two CCDs works fine most of the time there is still the odd game that migrates threads between the CPUs resulting in lost or inconsistent performance, and that would be especially bad with the X3D versions. But we'll see what the reviews show. Maybe it won't be an issue.

With that being said the 7900X3D is kind of iffy for me because you only have six X3D cores. Six cores is generally enough for gaming now, but four cores (with not SMT) was also enough for gaming for a long time up until it suddenly wasn't. My i5 2500K was a great buy, but my i5 7600K definitely was not.

No big surprise...

AMD confirms it has been 'under shipping' CPUs and GPUs to keep prices stable

AMD confirms it's 'under shipping' and closely managing inventory as PC sales decline, and inventory management technique that has also kept prices high.

Guess am waiting till April. 699$ 7950X3D. F that.

[demo]

I believe they want to sell the higher models first knowing damn well the 7800x3d will have almost identical gaming performance and would cannibalise their sales.. X3D chips are after all gaming focused chips, no one is buying the 7950x3d for productivity.

[pax]

Only reason I can figure the 7800X3D is a month later is that they need to build up inventory for that part...or they want us to buy the pricier models...

A whole month after (April) for the one that most people would like to buy. I`m not super happy with this decision. That being said, with all the back tracking that has been happening recently on the AMD web site concerning these CPUs, not sure I`ll believe anything until these are actually out.

[KAC]

Yeah, it's not like the damn thing is going to overclock worth anything. At this point I only need a board that can get 4 M2 slots at full speeds and doesn't mess up the PCI e lanes. Apparently that alone seems like a hurdle on stupid AMD platform in the past. Can you tell me which CPU and motherboard combo will allow for this (PCI e 5.0 16 X for gfx, PCI e 5.0 for 1 M2, PCI e 4.0 for remaining M2 slots X 3).

[demo]

I'm sure those will do just fine. Most X670E boards seem over engineered.

[KAC]

Those are like 500$ boards. Wtf?
Is the ASUS TUF X670E not enough? What about Prime Strix or whatever the ASUS X670E-A board is like?

[demo]

Go for an MSI Carbon or ASUS Strix if you don't want to stretch for an ACE or Hero.

[KAC]

What’s a good board? I am confused af about AM5. Seems all boards start at 300 smokes. I would like a X670E board but any known brand is 400+. I used to pay 400 for a CPU ffs.

Can someone link me. Most likely I might go 7950X3D.

[demo]

May as well as you also get pcie5 for storage.

[Nagorak]

What are your guys' thoughts on paying up for an Extreme board for PCI-e 5 for the GPU? Obviously it's not worth anything now, but if AM5 has the same longevity as AM4 do you think it would be worth it 4 or 5 years out? Will it be a decent difference at that point, or still not really relevant?

Extreme boards also tend to cost a fair bit more than a non-extreme, so I suppose you could also just save the money and buy a new board down the road probably for lower prices than currently.

[Nagorak]

Returned the 5600x and bought the 5800x3d instead.

Probably a good choice if you're going to be using it for many years.

[Tyr-Sog]

I just moved from a i5 6600k to a ryzen 5 5600x Yay me! Still working on the setup. Hoping to see some improvements.

Hrmm you might be right KAC. There's something odd about this announcement.. they might be duds.

I don't fully agree with the guy's reasoning. He has a fair point about some of the benchmarks that are picked out (they're comparing Zen 3 vs Zen 4 vs really comparing the effect of vcache). But even if the 7800X3D were to only tie the 5800X3D in games that vcache benefits (which seems unrealistic, it should be at least 10% faster from clock speed alone, plus you'd think a little from IPC), yet run at Zen 4 speeds in games that don't benefit, that would still be a really fast gaming CPU.

I'd guess it would be enough for the CPU to take the gaming crown, considering the 5800X3D is only about 10% down on average from the 13900K, and the 7700X is like 5% down from it.

You also have to consider how relevant the performance is in some of the games that the 5800X3D does poorly in. If you're already getting 400+ fps in CS:GO then I'd argue it makes no difference whether one CPU is faster in that game or not. I also doubt a seriously dated game like that will serve as a solid reference point for how future games will perform.

Either way wait for third party reviews, but I am hopeful about the 7800X3D.

[KAC]

I am waiting for reviews. Otherwise will throw a 13900K system together.

[pax]

Id just wait for reviews. 5800X3D was anywhere from no improvement to a couple slight losses vs the 5800x vanilla to 40% increase in a couple games. Averaging about 15% uplift so it depends what games you care for to spend the extra $.

[demo]

Hrmm you might be right KAC. There's something odd about this announcement.. they might be duds.

[KAC]

Hmm, this is not the kind of results that I saw at launch time. I am waiting for X3D procs and will pickup the one that makes the most sense.

[demo]

Of course I know its a different architecture. I meant scam in the sense that they locked 5800X3D without a real reason and now have this chip that is so close to the 5800X3D that it doesn't make sense.

On the 17% claim, honestly I haven't seen it. The 7000 series is getting its 15-17% gain because it also clocks about 0.6-0.7 GHz higher on single core and about 0.5-0.8 GHz on all core. I doubt, clock for clock it is really gaining that 17%.

Also given AMD numbers lately, I would trust their comments about performance as much as I would trust a Dutch pedo telling me there is candy in the orange van.

It's not close. They are claiming it's 20-30% faster than 5800X3D.

As for Zen4 uplift, 7700X vs 5800X is 22% faster in gaming here. Likely ~17% from IPC as claimed, and another ~5% from higher clocks.

Gaming dude. Don't care about productivity. Also those are handpicked benches already showing differences depending on app.

I thought AMD locked because of the v-cache can't handle over 1.35v so they didn't want to risk the returns.

[demo]

Not really, it's a different architecture. I remember reading Zen4 is 17% faster than Zen3 clock for clock. Along with higher clocks AMD are claiming a 20-30% improvement over 5800X3D. Not sure what the gains are for 7 series though, perhaps 10-15% over a 7700X.

Plus you have all the platform improvements, so I don't see it as a 'scam'. I do agree 5GHz is a bit disappointing though, would like to have seen it a little higher.

[KAC]

Yeah I just realized it. 7800x3D feels like a scam though. As if they allowed a 5800x3D to overclock by about 300-500 MHz, which tbh they could’ve done it already to this processor and it wouldn’t have broken. With just CO my 5800x3D jumps from 4450 all core to 4600 already. And seems there was headroom. New proc running around 5 G s seems like a scam and they will again charge 450 for it.

[demo]

I dunno, it only has 6 cores with v-cache. I feel like the 7800x3d and 7950x3d would be better options.

[KAC]

Need that 3D 7900X. Dope af.

[demo]

I just read this at another forum:

AMD is working with Microsoft on Windows optimizations that will work in tandem with a new AMD chipset driver to identify games that prefer the increased L3 cache capacity and pin them into the CCD with the stacked cache. Other games that prefer higher frequencies more than increased L3 cache will be pinned into the bare CCD. AMD says that the bare chiplet can access the stacked L3 cache in the adjacent chiplet, but this isn’t optimal and will be rare. Yes, the chip with the extra L3 cache will run games at a slower speed, but most games don’t operate at peak clock rates, so you should still get a huge performance benefit.

[demo]

Yeh scheduling will likely have teething problems. I'm wondering if the 7950x3d v-cache CCD actually boosts higher than the 7800x3d. Perhaps 200mhz higher? I'd definitely give the 7900x3d a miss, having only 6 cores with v-cache.


It's an interesting design choice, almost like intels hybrid design.. but with beefier e-cores.

[Nagorak]

It's weird to me that they didn't release any prices. You'd think that would already be determined at this point. Maybe they are spooked by Zen 4 sales and aren't sure how much they're going to have to cut them to get the moving?

Yeh but only one of the two CCD's has v-cache. The 5.7 boost is for CCD without v-cache. Interesting design choice, didn't see that coming. I hope the scheduler can correctly select CCD depending on load, or even which games prefer cache or clock speed.

I don't know, that looks to me like something that is not likely to work without issues. I'm wondering if the rated boosts are almost just for marketing purposes and in practice doesn't really provide much benefit. It's pretty easy to miss that only the non-vcache die hits those boosts.

[pax]

Oh scoot ya... the difference in cache is due to less L2 from the missing cores between the 2 top skus dang... It'll be interesting to see how it goes but with as much cache as a 3000 gen threadripper but much higher clocks itll be a good productivity choice besides a gaming one.

[Megaman]

These new CPUs will be great to pair up with your 4090s.

Kind of impressed the 7950X3D can run 5.7 ghz boost... Way more than the 5.0 boost of the 7800X3D, tho Id bet that one is probably a good ocer. These are not gonna be cheap tho. They didnt even bother to mention pricing...

[pax]

We should get some look at the new 7000 X3D gen tonight:

Rumor is the 7800X3D is about 20-30% above the 5800X3D...

[KAC]

I will jump on Zen 4 X3D for sure. Been waiting for it for a while. The 5800 X3D is not a bad processor either. Just takes a while to cache shaders. If they do a 12 or 16 core X3D I will be all over it.
