Review Zen4 3D review thread

[Hitman928]

Thread to focus on Zen4 3D cache CPUs.

New gaming king (as most expected), though the 2 CCD 7950x3d does seem to have issues with some games, more than I would expect of it getting stuck on the "wrong" CCD. I imagine it will get cleared up with subsequent updates but we'll see. Simulated 7800X3D showed no such issues and overall has the gaming lead (real product might be slightly slower though depending on in game clocks).

Computerbase also has the 7950x3d as the gaming champ. They (and TPU) also show that efficiency while gaming is extremely good.

Ryzen 9 7950X3D im Test gegen 5800X3D und 13900K(S)

Zen 4 3D ist da. Im Test erweist sich AMDs Ryzen 9 7950X3D gegen 7950X, 5800X3D und Core i9-13900K(S) als schnell und effizient.

Just to toot my own horn a little, it landed spot on with my prediction of fastest gaming CPU but not significantly so over a 13900k on average, but with much higher efficiency.

Additional reviews, will add more later.

Excellent CPU the 7800X3D but for 2023 its too expensive for 8-cores, Im starting to believe we are in the first stages of CPU stagnation again and this time is AMD.

for this to happen zen 4 and the accompanying x3d would have had to have a minima improvement over zen 3 while lacking the necessary competition. If amd stagnates they lose to intel who's been increasing performance at a greater than historic rate for several generations now. this isn't amd stagnating, this is amd grabbing consumers by the jewels and squeezing them. Don't need tons of cores but care about gaming? buy a 7800x3d. It'll run cooler and use less power than a 13700k or 13900k.

Past experience. AMD only got around to allowing zen3 on 300 series boards after time and customer outrage as it were. Along with the cheapo boards getting support before the 300 mobos. I have no faith that some little thing won't pop up that means you can't run a Ryzen 8000/9000 in a 650/670 mobo. Hopefully it won't but why trust these companies on this stuff at all?

The problem was the bios ROM size on the AMD boards could not hold the data for all the CPU's from zen1 to zen3 being 64 or 128mb, and even so they made it work. With AM5 as far as I have seen all boards are sold with 256mb flash memory.

That's me, and also because I'm hoping AM5 will support zen6.

I'm surprised by how often the 7800X3D beats the 7950X3D across many games. No wonder they were holding off on releasing it. It shows the Windows scheduler really doesn't work properly yet. The 7950X3D might be interesting in old games that are CPU limited by one thread.

this is what I alluded to about two months ago. they released the 7900x3d and 7950x3d to get every tom dick and harry to buy it thinking it was hot stuff and it is but at a higher asp.amd pocketed big money on this since the 7950x3d has been consistently selling out and may continue to sell out idk.

Now those who bought the 7950x3d but now want this will sell it on the used market and buy the 7800x3d, amd double dipping into their wallet. it's not that amd was afraid of harming sales, that's one part of it, the greater larger part is they knew they could make a ton more money than they would have and double dip into the wallets of many. It's not different from the AMD of 20 years ago when they had the better product then too. if you're old enough you'd remember amd charged much more than intel in those days for a lot of products but it was worth it.

 

[A///]

fingers crossed it will but I'm not expecting much past zen 5 3d mate. Intel would have to put pressure on amd through arrow or panther for them to take a face savng move such as that. as it stands now intel is competitive but also sports a self immolation feature built into their processors.

 

[biostud]

Everybody has their opinions. The higher TDP of the x series Zen 4 doesn't amount to much. Other than using a lot of power with a high and very hot running CPU's compared to Zen 3.

You are better off with a 7700 or a 7900 and OCing it out of the box. Lower power consumption and nearly if not identical performance to the 7700x at a lower price. 65w is real bargain.

I know (7700 or 7700X is the same to me), and I could have bought long time ago. But I also know that for the next four years I would regret not getting the 7800X3D instead. It's not a logical reasoning, but that is the CPU I want.

I have nothing bad to say about the 7800X3d if that is what you want. Go for it.

good luck getting one any time soon. I expect it will be hard to get for months.

 

[blckgrffn]

If it were a time/cost/feasibility thing though, why didnt they come out with the 7800x3d first? Would have even given them more time to work on the scheduler. Seems like a profit motive to me, but I dont really have a problem with that. Everyone knew the 7800x3d was coming, and if they were too impatient to wait, then they have to pay the early adopter tax.

For sure. I’ve said as much earlier. But for those who wanted or needed to wait, the time is now.

 

[Panino Manino]

Those who said AMD should feature the energy efficiency more prominently were right, this is incredible.
Makes me think CPUs should try so hard for the most performance possible, not by the usual conventional ways.

The only bad part is the price. They are surely making huge profits.

 

[eek2121]

I got shouted down on this forum for asking the same question back during the Zen 4 launch. It was after the 13 series of Intel CPU's basically smoked the Zen 4 processors. Then AMD released the non X variants consuming 65w. That would have been far more compelling because they would have continued AMD's sipping power concept. The X3D CPU's would have taken the gaming crown on launch and the non X CPU's would have won the efficiency title. Both important in my opinion.

The only thing smoking anything is you. Intel smoked AMD at absolutely nothing, except in terms of power consumption, of course. The 7950X is extremely competitive with the 13900K. Winning most, and only losing a few benchmarks, despite having a 'handicap' in terms of power consumption and cores. A tweaked 7950X will absolutely spank a tweaked 13900K any day of the week, except, of course, if the 13900k is allowed to consume 2-6x the power consumption.

Are we surprised though?

 

[Hail The Brain Slug]

Are we surprised though?

We shouldn't be, this was well predicted by the "simulated 7800X3D" benchmarks many reviewers did by disabling the second CCD on the 7950X3D.

When AMD finally gets around to fixing up the scheduling issues still remaining on the dual CCD SKU's it should even up.

Intel is too concerned with eating glue to make their processors more energy efficient.

 

[Abwx]

At 35W it would be on par with a stock 5800X3D, zctuzlly those X3D CPUs would be perfect for gaming laptops, eventually they ll release such dedicated SKUs but even then an OEM can use the DT part for such products, albeit lacking the power optimisations done on the DTR parts.

I'd like to know who would be silly enough to do that. That's a terrible path.

If someone wanted the absolute best CPU just for games, they would just disable the frequency CCD on the 7950X3D. Not sell the 7950X3D and get a lower clock frequency 7800X3D.

7800X3D frequency at stock during gaming is between 4.8GHz and 4.9GHz. A 7950X3D cache CCD will be consistently over 5GHz.

AMD has not only said that compatibility would last through 2025+ they posted it on a slide during the AM5 launch. No way they back out on that. They know users loved that about AM4.

Source? FMAX for 7950X3D V$ die is 5050MHz stock. What's the FMAX for 7800X3D?

If the X3D chips are anything like my 7700 I don't think they would be good mobile chips. My CPU idles around 38W. While they are much more efficient than Intel as load increases, they consume too much at idle/low use.

Fmax on 7950X3D CCD0 is 5250MHz. Not sure where you got 5050MHz.

Playing around with a -20 to -30 CO offset on a 100MHz bclk I can hit fmax quite frequently.

Edit: Also note, v-cache CCDs have Fmax fused. It cannot be raised.

FMAX is only 5250 when PBO with +200MHz offset is enabled.

No.

Read the article I posted. 5250MHz is stock. As I said, positive offsets will not work on v-cache CCDs.

I should know. I own the freakin CPU!
At stock boost clocks will often go above your stated 5050MHz and hit 5250MHz max. A negative CO makes hitting Fmax more likely.

Lol OK I own it too. Enjoy it.
