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.

All 7xxx3D CPUs have a TPD of 120W and a max 162W PPT. The 7950X3D and 7900X3D have two CCDs to share the power. The 7800X3D has one CCD for all that power.

That's why you see some gaming benchmarks higher for the 7800X3D compared to the other two.

Disabling the frequency CCD on the 7950X3D will allow the V-Cache CCD to use all the power while simultaneously boosting higher with it's increased Fmax.

Just wanted to put that out there if it wasn't clear for some.

 

[AdamK47]

Lol OK I own it too. Enjoy it.

If you have +200 set in PBO, turn it off. You'll see there is no difference on the V-Cache CCD.

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.

there was never a plus, it was through 2025 at a minimum. they made no extra promises. 2025+ means beginning with 2026 and later years. you seem to forget amd didn't want to include later zen support on older motherboards whether or not their eeprom had sufficient storage space. after much outcry from their customers AMD allowed aib's to push new bioses to support zen 3 on older am4 boards. did you also forget amd left consumers hanging with an expensive strx4 socket that's only useful for 1 generation of cpu's?

2022: zen 4
2023: zen 4+
2024: zen 5
2025: zen 5+

Amd can say beyond and make whatever promises they want but remember what was pointed out to you here and how they implied am4 will still get new hardware or updated hardware but nothing's come out since then that the majority of mainstream users will want to buy. There's a small market for any apus.

 

[A///]

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.

very simple

the 7800x3d performs on par or slightly better than the 16c in games. someone who only plays games on the computer won't find a useful need for more cores. They can turn around and sell their used processor for msrp or higher just as people have been doing for a few years now on sought after hardware, during a pandemic or not. Why not recoup your money if you're never going to use or need the other 50% of your hardware you've disabled because it gets in the way of gaming?

on the intel side it would be like buying a 13900K only to play tetris on it when a cheaper potato would be beneficial to your wallet.

The guy that does that is an idiot.

The guy that does that is an idiot.

your opinion is that a lot of gamers who bought the 7950x3d with no use case for 8 of the 16 cores when all they wanted but couldn't wait for the 7800x3d and now have an avenue of recouping their intiial spend if not more to get the 7800x3d which has 99% of the gaming performance at a much lower cost and won't be a waste of cores that would otherwise get disabled are idiots?

Yes. Impulsive idiots.

 

[A///]

Yes. Impulsive idiots.

Idiocy for buying the product without impulse control I'll deem ok because I agree with it, but not idiots for realizing they can turn around and sell the processor now for MSRP or even higher and recoup their costs. It's sheer luck they can. these people selling them for msrp or higher and moving on are better than the flood of dual ccd buggy behavior that may come about in future and clog up support forums with the same questions. only my 2c.

I impulse bought faulty space heaters 20 years ago and barely sold them before my house caught fire or lost money on them. I'm sure the next person who used them dealt with the same issues.

faulty space heaters = intel pentium 4s

in case certain people won't get the joke and think I really did sell strangers malfunctioning space heaters that posed a fire hazard.

You're not going to back down from your initial assertion I quoted earlier. I get it. Internet and all that.

Think about it from a macro level. A person buying a 7950X3D is not going to go through the effort of selling their CPU to get a lesser one in order to recoup $100 to $200 when the rest of their components are most likely also high end and expensive.

So yes, that hypothetical person is an idiot.

Why should I back down? You have your own opinion and I have mine, except I've seen people do just that as I've pointed out once their dunce brain has realized they messed up and need to sell fast as possible or return if it they're in a return window.

What I usually recommend to dunces like that is to have a card with return protection that's outlined by max amount and exceptions by their crediter and use that card to buy hardware under the yearly limit for the card, if it's over then they're screwed to noon on a friday unless they can offload it to the next dunce who'll pay msrp or over msrp on ebay or similar.

Man, this guy you're describing... sound like a person that needs reminding to simply breathe.

Someone that shouldn't be buying a 7950X3D to begin with.

You've been around this hobby as long as I have to know there's plenty of those people who have zero patience even those in their 50s and 60s who've been using computers in one form or another for decades and decades. to make it clear I haven't bought a 7950x3d if you were trying to hint that it was me I was trying to defend. I'm opting for the 7950X but won't be building for another 2 months.

the fear of missing out gets to those people real bad.

I don’t think you need to disable CCD1 in BIOS to force the game on CCD0.

Setting up all the software on process lasso doesn’t take that long. In my opinion relying on Xbox Game bar is just an awful native solution from Microsoft and AMD.

Leaving CCD1 enabled still eats into total available power.

Just for the record, I don't disable mine. It still does have advantages is other titles. CP2077 being one example.

Ah yeah true. In my eyes CCD1 is busy doing some
work while CCD0 is gaming!

Xbox game bar is used to help Windows assign game to CCD0. Really dumb imo because a lot of software won’t work with that.

leave it up to M$ to over complicate everything. when I was a kid and computers were just starting to come out they said life will be easier in the future. they were partially right but now you spend more time setting stuff up than enjoying the damn thing.

 

[Joe NYC]

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.

As opposed to other 8 Core CPUs (7950x3d, 13,000) that cost $700 but have an appendage of additional cores that does not do anything for you?

 

[Joe NYC]

If I was still an AMD shareholder I’d be pretty pissed that this didn’t launch with AM5.

Can somebody make a good case why it didn’t?

AMD is the lead customer of this type of stacking (Hybrid Bond) for TSMC.

Stacking of 7nm on 5nm was not available as of the time of AM5 launch. Zem 4 V-Cache are the first production parts to use this combination of technologies.

 

[AtenRa]

You can have 8 cores for $329, but obviously the fastest gaming CPU will be sold with a premium.

I might be wrong, but I don't expect games to take good use of more than 8 cores for the next four years.

2017 - Ryzen 1800X 8C 16T = MSRP $499
2018 - Ryzen 2700X 8C 16T = MSRP $329
2019 - Ryzen 3700X 8C 16T = MSRP $329
2020 - Ryzen 5800X 8C 16T = MSRP $449
2022 - Ryzen 5800X3D 8C 16T = MSRP $449
2022 - Ryzen 7700X 8C 16T = MSRP $399
2023 - Ryzen 7800X3D 8C 16T = MSRP $449

Sorry to say but this is stagnation, I could understand why 5800X increased (vs 3700X) the MSRP at $449 back in 2020 with the Ming and Cov pandemic but having again an 8C 16T at $449 in 2023 , we are not going forward but staying at the same spot .
We need a Ryzen 1000 moment again soon otherwise we are reaching the Intel 2011 to 2017 time of 4C 8T parade but with a little bit higher IPC this time.

I have been looking at the 16c/32t side. I forget what the 3950 was, but I think $800. The 5950x was definitely $800 Then the 7950x was $700 and now its $550. A whole different picture.

That is why it is good Intel is there for competition and you can buy a 13 gen if more cores are important to you.

I understand your reasoning, but personally I don't have any work/games that requires more than 8 cores. And I would like less expensive 8 core CPUs, but if AMD kan keep up generational improvements around 30 percent ST performance, I don't think it will happen.

Just imagine where Intel would be today if they had 30 percent improvement with every generation from 2700K to 11900K :O
