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.

Average increase at 1080p of the six games is 7.7 percent.

If that's "free" performance due to something exclusive to MSI mobos, great news for those mobo owners.

It's interesting to watch that not only does the CPU consume less power, the GPU does that as well all while delivering slightly more FPS.

I notice this too. Somehow the framerates are a bit higher but GPU power is 30W lower than before in the exact same games and situations. Maybe it's allowing the Nvidia drivers to run more efficiently somehow, or using less GPU due to being maxed out at 120fps.

My guess is those are just "safe" PBO+CO presets.

Imagine the irony if it was due to Zen4 having AVX512 and Intel having dropped the feature they spent years hyping!

a few years ago nvidia dropped intel to use epycs in their systems and only recently did nvidia use xeon in some applications i suspect amd will be the choice again going forward since intel is a very lost little boy in a big boy world. Epyc for the mo is very untouchable for intel. you'd only choose intel for specific loads it's better on than amd. I'd expect intel's dc share to keep slipping and mobile is next. desktop is dead locked for the most part because of how much consumer purchase power existed during covid.

I think the main problem was that Intel just did not have a platform supporting PCIe Gen4 until too late in the game. NVidia had a no choice but to use EPYC.

Now, that both Intel and AMD are equal in support of Gen4 and Gen5, NVidia can go with inferior Intel product, only to make their Grace CPU look more attractive (when it launches), in comparison.

Alternatively: they just got SPR for cheaper.

They don't really care about the performance of the CPU, just how much PCIe bandwidth it has, so it's a lot easier for Intel to be price competitive for them.

no ice lake was already shipping when nvidia made that decision. they went for epyc for the superior performance and price. goiing with spr means the price was right and maybe more extensibility than genoa. amd may have also said they couldn't supply nvidia enough units when the demand from their major partners is greater and more important or implemented a time out period before nvidia can use them because amd wanted to incorporate them into their dc vision products first idk. nvidia + amd performance used to be worse but i was basing my previous post on memories i had of using amd's junk proessors /w a nvidia gpu at work.

amd messed up by pissing off a lot of people with intel like maneuvers and pricing for tr and epyc. intel offering extensibility will hopefully mean amd can unclench their teeth and give people what they want. ryzen pricing can be better too.

I am pretty sure it was the opposite. Quick search gave me:
- Ice Lake release date: April 6, 2021
- A100 release date: May 14, 2020

that may be general availability. inspur began offering icelake-sp a100 systems in june 2020. inspure is an nvidia partner.

Yes, and the memory timings are probably Buildzoids safe tweaks

But looking forward to next Agesa update 1.0.0.6, seems to reduce boot time, lower idle power usage and have better memory stability.

I also look forward to receive my 7800X3D...

Does it solve the idle power consumption that some motherboards had?

It appears to improve idle power for me on 1406 (AGESA 1006) vs 1223 on my ASUS board. I would typically idle in the teens (15-18W) as measured by Adrenaline but now I can idle at sub 4W:



This is with Steam, email, browser open so true idle maybe even less.

Well it turns out I was already on 1.0.0.6. It was a BETA version so I upgraded to the official version. No real change for me. Maybe 3W less at idle and a couple of degrees lower temps.

Beta BIOS 7E10V151 - idle was typically around 38W (these are all PPT values) today it was near 40w, but I think something was updating in the background, should've checked. CPU Tdie was ~50C
BIOS 7E10V15, default BIOS settings - idle around 24W, 47C. Took ~34s to boot from pushing the power button.
BIOS 7E10V15, XMP enabled only - idle around 37W, 50C, took 47s to boot
BIOS 7E10V15, all my OC settings - idle around 35W, 48C, took 47s to boot

This is what I have seen since I built it and "tuned" it. It might be slightly better today than it was previously, but nothing like what others are seeing in that Reddit. It makes me wonder if they had something wrong to see those drastic changes or if I have something wrong, lol. Performance wise though I am getting good numbers though.

That's very nice.

I have to finally get off my behind and put together the system. I am procrastinating a little on researching cases and power supplies.

I think I will stick with a 6600 XT from another system for a few months and wait for 7800 XT (Navi 32).

I had this idea of of going with a water cooling, but that would need even more research. It seems that the 7800x3d is just fine with an average AIO, and maybe I will get one of the higher end models of 7800 XT, like the PowerColor Red Devil, and it should be very quiet.

Where are you getting the wattage numbers from?

Average increase at 1080p of the six games is 7.7 percent. Not sure one could tell the difference in real world gaming, but i guess it does give a boost if you are looking for bragging rights vs Intel or non-X processors.

I have this board and tried this out but got random reboots in Windows. It's probably better to just use the AMD tool. In general I've found the motherboard auto-OC features are too aggressive and overvolt the CPU too much even when they work.

Does the new agesa effective twin chiplet processors? I'm curious whether it affects the iod on Zen 4 and power usage through various stages of io compute.

7800X3D on A620

Why didn’t he isolate the boards and Coolers as variables? With the way he did it it’s hard to know if the board or the cooler is responsible for the clock speed difference.

 

[lopri]

I'm loving the performance of mine, but the power consumption everyone is talking about is not a strong point imo. The idle power is 30-40W higher than my old 10700K/Z490 setup. I can't tell if it's the CPU or the platform. The X670E heatsink does get quite hot, too hot to touch even when the computer is not doing anything. The video card is also a bit power hungry on idle (because of the AIO pump), so the total idle power is at least 50W over what I had a year ago.

promontory is a power hog for what it is and gets hot whenever there is a sizable load. (e.g. NVME transfer) It Is probably not high on AMD’s list (of things to fix) though.
