Why everyone say Zen 5 is bad ?

[Dr. Dro]

In my book, this is a performance increase per watt of 13%.

As Alexander J. Yee (Mysticial) one of the authors of y-cruncher wrote on numberworld.org, it really depends on the workload.
Some instructions (AVX-512) saw a 2x increase (I'm not kidding) others 0%.

The AVX-512 gain is massive, that's for sure. Not only that, it also pulls off AVX-512 without heating into a supernova, which is a first - Skylake-X/SP, Cascade Lake-X, Rocket Lake and Alder Lake (earlier samples), as well as Zen 4 to a lesser extent, all do.

Which begs the question, AVX-512 is such a foreign and utterly useless instruction set for consumer-level workloads that makes me believe that AMD developed this architecture and chiplet primarily with Epyc in mind, tailored to the AVX-512/VNNI requirements of AI customers. Essentially, this is a processor for the AI cloud, downsized for a desktop.

which is a first

TGL did it fine IIRC although it was limited to laptops or NUC.

iirc, Tiger still took a massive clock speed hit executing AVX-512. Either way, amongst high-performance desktop-class processors, this one is the first that does AVX-512 this competently and efficiently, no doubt thanks to the native 512-bit FPU

The secret is to run the hardware you want and not care what everyone else thinks

This is probably the wisest hardware-related post I've seen.

 

[R0H1T]

It was TDP constrained hence clocks took a nose dive.

Tiger still took a massive clock speed hit executing AVX-512.

I have a 6 core laptop & it beats the 5800x on some synthetic benches.

 

[GhostRyder]

I agree, I think that the point of this part is to show max efficiency while keeping performance the same or higher. It can be unlocked to provide more performance but right now 88watts for a chip that has 8 cores and performs like it does is great. Will be even better in mobile spaces I assume.

We will get a better picture of what Zen 5 can do with the Ryzen 9 parts. Now that may end up being disappointing but for right now I am optimistic.

Because it lacks cores

IMO, the number of cores isn't too relevant when Windows is still sporadically being a piece of shit with how it distributes tasks across the cores and its obsession with core0, plus the lack of optimization in the rest of the software around us to take advantage of more than 8 cores (if that, even. Lots of software around probably doesn't know anything beyond 4, maybe 6 cores still).

people feel there is no initiative to buy.

I think that's fair, though. IMO, buying either 9700X or 9600X makes more sense to people upgrading from old platforms (pre-Zen2), but if you're in Zen3 or 4, there's not much incentive unless you have some really good use case that benefits massively from Zen5 processors.

Comparing benchmarks with the previous model in TPU reviews, well except for the first one.

                   1800X    2700X    3700X    5800X    7700X    9700X
Cinebench R15 MT   224%*    10%
Cinebench R20 MT   -                 23%      24%
Cinebench R23 MT   -                                   45%
Cinebench 24 MT    -                                            5%
Games 1080p        -        4%       7%       5%       11%      2%

*AT reviews shows that the 95W 1800X is 224% faster than the 220 W FX-9590 in R15. I just had to add it.


I'm not sure the 65 W TDP makes such a difference after comparing with the 7700.

                7700    9700X
Cinebench 24 MT -       9%
Games 1080p     -       3%

 

[Devon68]

Well I'm happy with my 7700 non X. Might consider the 9800x3d when it launches just to stay up with the tech

The one after that is hopefully more interesting, I just hope it won't be called 1-0-8-0-0-X-3-D.

Nah...."AMD Ultra 18X3D"...

Dunno how they will survive without an AI in there tho..

Zen 5 is "DOA"

Never used in comments below article or topic for ZEN 5 in TPU... Excluding your thread here.

Well you can always go 9999 xxx right?

 

[GreiverBlade]

Given the hot mess Intel is, right now...

Even my R7 5800X3D is a prime CPU
well, disclaimer, since I got it cheap... not even 9x00 series can make me upgrade...

Tho if I still was on my i5 6600k or R5 3600... I would definitely go for the 9700X

The 7xx0 series were also looking good but the DDR5 requirements weren't good looking...

right now I am enjoying perfect 1620p60 in every games I play without any crashes

But AMD is really looking, to me, more and more, the top choice...

As I mentioned once, I gave Intel and AMD a fair share of my time since mid/late 80s.
But recently, Intel is disappointing me quite a lot...
Childish pr campaign,
biased bench under chiller or ln2
and "optimisation" that became performances hit once vulnerabilities induced by them, got patched.

 

[Vayra86]

Apparently there's a lot of room to improve performance by increasing power and overclocking. But I understand why they are doing it this way... just look at intel.

People always say they miss they days when they went into the bios to increase performance and not decrease it. Well, here you go.

Right? I remember not too long ago we were screaming things were clocked too high out of the box, now we're screaming a chip's efficient at stock? Dafuq?

I guess you didn't saw, for example, Intel's 11-th gen comparisons anywhere ?
But that may be just me reading and watching more than few reviews...

In general, I specified a specific architecture in my comment. Also mentioned TPU not other websites. Otherwise, this abbreviation is actually used here for a number of other products, which is not relevant to the topic.

I thought so as well, then I compared the performance with the 65 W 7700 and sobered up.

 

[FoulOnWhite]

Iv seen him take it to dinner wearing his best blazer.

But it’s still a really great chip I don’t blame him at all.

And so so stable for nearly 3 years fo me too. When i do upgrade be it AM5 or 1851 i will keep this trooper of a cpu/board combo.

 

[AusWolf]

I don't agree with the Ryzen Master thing, I don't OC from within Windows & have never considered it stable although ideally your own software should be able to do it! But I have anywhere between 50-500 third party games/applications (i.e. non MS) installed at various times so I know there's a lot of conflict that may lead to system instability. This is why I do it from the BIOS, always!

I think support for Ryzen Master should be dropped. I wanted to try it once, but it didn't work, so I gave up on it. I don't think a CPU should be tuned in software anyway, it has always been a bad idea.

Yeah! Give us back pencil mods and BSEL mods!

 

[AusWolf]

Give me one reason why tuning in the BIOS should be ditched. My thinking is, if it's not broken, don't fix it.

Right over his head. I caught it though
