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.

What do you consider cheap? The cheapest so far is an ASROCK $125 mobo.

Yes.

7800X3D official performance slides from AMD released by Tom's Hardware:
AMD Shares First Official Ryzen 7 7800X3D Gaming Benchmarks vs Core i9-13900K, Up To 24% Faster

Reading between the results, it appears to show exactly what we all suspected - 7800X3D will be the gaming chip to get and that's why AMD is launching it later - to avoid cannibalizing sales from the 7950X3D and 7900X3D.

7950X3D may be a few % faster overall, but it's hard to argue with a chip that costs $250 less and doesn't have an asymmetric setup. It also costs $130 less than the 13900K.

April is only a month away...

Looks like the 13% IPC+10% clockspeed vs the 5800X3D is spot on.

Even cheaper B650 models are coming soon.

$124.99 for ASRock B650M micro ATX motherboard
$127.99 for 32GB G.Skill DDR5-6000 CL32 FlareX EXPO kit (should be Hynix memory chips @ 32-38-38-96 timings)



Yup, AM5 is finally budget-friendly.

We can hope that's what is going on, that AMD is just trying to get some higher ASP sales.

Alternative is that the supply is just coming online, and that it is still below anticipated demand. In which case, why not release a low volume part a month+ before the supply can catch up for the high demand part.

What is better timing, 32-38-38-96 or 30-40-40-96?

 

[IEC]

What is better timing, 32-38-38-96 or 30-40-40-96?

About the same. Both should be Hynix M-die (small possibility Hynix A-die).

Pick whatever you like, should end up with essentially the same result on the AM5 platform, particularly if you are manually tuning to Buildzoid's timings. If you want an EXPO option mine was cheapest for DDR5-6000 CL32 or better. If you're okay with XMP the CL30 kit wasn't much more expensive.

For many people sure. But mATX is a hard no for me. ATX boards seem to start at $200, so $200-250 for one I'd want for awhile. Not that I am in the market. A lot of them have limited PCIe and/or SATA as well. I have a 16x and two 1x PCIe cards so I can still use M.2 and 6 SATA devices.

I still think they are miling customers more now that AMD has proven itself over a long period of time and that they may have to support quite a few new new generations of motherboards and thus lose future sales. Says the one who went from a 2600X to a 5700X without having to buy and swap a board. Used to be a thing back in the 939/AM2 days and probably before that with socket 7, etc.

 

[A///]

Latest words on the tech street were CES 2024 for Strix Point and Q2 2024 for Turin, no idea were Granite Ridge fits in all of that but possibly in-between.

Not even a whispers on next gen chipsets tho, yet.

Latest word for Zen5 tape out were quite awhile ago and they were surrounding TSMC's N3 woes and if AMD can decide plan B to stay on N5/N4 nodes instead. Which TBH sounded like typical WCCFTech clickbait, so haul in some trucks of salt.

I mean specifically about tape outs is not something I've seen AMD comment on. I would not place too much emphasis on any news about tsmc that isn't from their mouths because it almost always turns out to be wrong.

I specifically chose the current cheapest AM5 board to purchase so I can review it, warts and all.

Other than the cheapout on USB ports (which it has enough headers to overcome) and audio (crappy AC) it actually appears to be a decent board. PCIe 5.0 capable top m.2 and PCIe 4.0 for GPU and secondary m.2. Only 2 DIMM slots which should lead to better memory tweaking vs 4 DIMMs. 8+2+1 DRMOS 50A phases (I suspect it is a doubled 4 phase for vCore). BIOS Flashback built-in. It's already substantially better spec-wise than the B350M I reviewed back with Zen 1, and costs about the same in inflation-adjusted dollars.

Either way, I get to disassemble it to see if the components are worth the asking price. And I have a nice X670E board to compare performance to. We'll see if it's a decent entry point to AM5 or if ASRock cut too many corners.

The 13900k is doing better that I thought and with DDR4, but Zen 4 3D is beating it at half the power consumption. ~120 vs 60 watts...

13900K is a beastly CPU.

Don't forget the 3D is doing that well with only 6 cores. While the performance is impressive, turning off that CCD is saving power.

13900K ≠ 6 cores ≠ CCD

CPU will go into infinite loop trying to figure out how those three are related

 

[DAPUNISHER]

I should have separated paragraphs, to avoid confusion. I was referring to the 7900X 3D after the first sentence.

 

[igor_kavinski]

The results are intriguing but the RAM speeds are unrealistic for the majority out there.

5800X3D @ 3800 MT/s CL15

13900K @ 4100 MT/s CL16

7900X3D @ 6400 MT/s CL30

I wish we lived in a world where stock XMP/EXPO speeds/timings were like that.

But it's good to know that we can pay for 24 threads and use half the CPU for maximum performance

I would prefer if AMD allowed the 2nd CCD to disappear within Windows without having to reboot.

 

[DAPUNISHER]

He clearly shows they are tuned. Also shows an example of what stock EXPO would look like.

I think it is important he does tune everything. Otherwise we get mired down in post after post where we get spicy because the results don't include it.

 

[igor_kavinski]

This graph deserves being reproduced here:



@Zenoth Are you happy to see the 7900X3D beating the stock 7950X3D?

 

[igor_kavinski]

Otherwise we get mired down in post after post where we get spicy because the results don't include it.

Or AMD can give us a DDR5-6400 CL30 EXPO kit.

I KNOW what you are gonna say

 

[Kaluan]

I would prefer if AMD allowed the 2nd CCD to disappear within Windows without having to reboot.

I suppose, AMD also needs a hardware scheduler. If this is the way they're going forward with Zen5. IF.

With potentially 16C CCDs coming with Zen5, it'll be interesting.

 

[Mopetar]

Price can vary each hour.?...

Yes, that is quite normal here in Denmark were the usage is monitored digitally.

Electricity everywhere is usually priced at an hourly rate. The idea is that when usage increases, the price should also go up to incentivize people to cut back or to delay consumption until off-peak hours.

Not true for the southeast US. It's rare to see Time Of Use rates. It's usually reserved for special large industrial customers. We are charged flat rates. Some used to have winter and summer rates, but most have abandoned those as well.

My electric bill is so complicated, I can't even tell, but it definitely has hourly, and also total use and all sorts of other rates.

@ondma

Fix that post where you quoted Igor please. It has no personal commentary.

As to the power savings, try recalculating for our friends in Europe that are paying much more for it. We have members in Denmark, it ain't $50 for them.

And on the point of 50$. Doesn't matter what else the system is running. Because $50 is $50. Throws the talking point about saving money by buying a skt1700 with cheaper boards and DDR4 right out the window.

post 310 was meant to be a reply to igor. Somehow I messed up and it ended up as a new post. In any case, the cost of electricity I quoted is for where I live. I think that is a pretty normal rate for the US. Yes, 50.00 is obviously 50.00, but my reply was in context to igor's comment that you could save enough to "buy a new cpu", which obviously will take a long time at the cost I pay for electricity.

Hard to read, but its essentially $0.15 per kwh. And Europe appears to be about $0.52 or more than 3 times our rate. So the difference between a 142 watt 7950x and a ~250 watt 13900k is considerable per year. My 64 core 7742's are only 225 watt !
