Switched to chip only power after people kept complaining about wall power.

Honest question: what kind of wall power testing would you like to see, and why? and how does it improve the results vs chip-only?

I'd like only to point out that CPU power, if software-reported, might or might not be inaccurate depending on motherboard settings. On Intel, it relies on the DC Loadline parameter in advanced BIOS settings to be correct (it should be set so that VID matches motherboard-reported die voltage/vcore under all-core loads). I am not sure if a similar setting exists for AMD as well.

94C at stock. Ooooof.

Are you surprising ? 12900K is still at 99'c ! everyone knew that going to lower nm means hotter CPU.

 

[EzioAs]

This is about as awesome (or rather mediocre) as the alleged performance of the RTX 4000 GPUs. The fact that efficiency isn't improved significantly while drawing so much more power and running so hot isn't a good generational upgrade by my own criteria.

Thanks for the review

@W1zzard
What's up with the MySQL test? it looks obscenely low

I'd love to have a Unity Engine game included, looking forward to the full 50 game test.

Not using software measurement of course.. these are trash .. i'm using proper physical measurements

edit: any thoughts where in the text i could clarify that, so it's more obvious?

Yeah, I noticed that, too, and retested it several times. No change, no idea what's happening

I mean the ram, Cooling, chipset all of these stack up must be pretty significant.

Right .. so you're looking or some kind of "platform power" number .. in idle? load? gaming?

 

[SLObinger]

I think when you look at the overall platform plus the CPU gains Zen 4 is a very compelling upgrade. Perhaps held back a bit by DDR5 maturity which will only improve.

 

[Pumper]

94C at stock. Ooooof.

Steve said in GN review, that AMD design Zen4 to boost like GPU, with a temp limit. So it goes to 95C in seconds and stays there, but does not throttle.

Perhaps a small box with the methodology could be added either in the beginning on the page or at the end; personally I assumed it was the software-reported value, as used by many (most?) people when referring to CPU-only power. Physical measurements might or might not take into account PSU and/or motherboard VRM efficiency, so some clarification could be useful in this regard.

 

[SLObinger]

@W1zzard excellent work as always. Like the new test setup and methodology changes.

 

[Legacy-ZA]

Suffice it to say, this is the generation I wanted to upgrade to initially, but my old PC was just well, too old and well, dead. That being said, I am still very happy with this setup, it will probably last me a good 7 to 10 years.

Oh and AMD, well done, can't wait to see what you have done with RDNA3, I hope you slaughter nVidia, and at a good price range too.

Lol I could swear I added some text at the start of the power measurmeents page .. will fix later today

 

[ModEl4]

Lol wtf.
AMD claimed 7600X was 5% faster than 12900K at 1080p high, and in TPU 1080p Ultra/high, 7950X is only 1.6% faster than 12600K, rofl!!!
Also there are other major failures (it was supposed to be faster in emulation especially in RPCS3 and it's slower in that especially 7950X/7900X vs 12900K/12700K, gaming power efficiency if you exclude 7600X is just at Alder's Lake level, in the vast majority of the multithreading rendering and Video encoding tasks 12700K and 12600K are better than 7700X and 7600X, cooling requirements are at similar level of what Alder Lake needs etc.)
Just wait for Raptor's Lake reviews and then decide!

 

[lsevald]

I would like to know what clocks these CPU's are able to sustain in a "more worst case scenario", like under Prime95 or maybe even Blender. The Clock analysis chart is interesting, but seems to be more type of instruction focused. What happens to boost and clocks at different temps and power loads?

 

[Gameslove]

Thanks for the test. Ryzen 7 5800x3d stay stong in the gaming. Ryzen 5xxx series gamers no reason to upgrade AM5.

 

[CrAsHnBuRnXp]

Is it just me (could be reading the chart wrong) but the overclocking shows slightly worse performance over stock?

Honestly, you cant compare 12th gen to AMD 7000. By all rights, AMD 7000 should beat Intel 12th gen. Ill wait for the comparisons for 13th gen and AMD 7000.

Said apple with 4nm and much cooler than prodecessors.

Low clock vs High clock , really?

 

[defaultluser]

And STT AND gaming say yes.

yeah, zen 4 is in need of a 3d treatment to enhance efficiency once again (and now we can see how much improvement those APUs get with 3d cache)

 

[Jism]

And derbauer already shaved off 20 degrees off those cores.

 

[W1zzard]

So it goes to 95C in seconds and stays there, but does not throttle.

That is not true. It will reduce the clock speeds to stay at or below 95°C. In my definition that's "throttling", even if it's very mild (when you have decent cooling)

 

[Ravenas]

Thank you for the review.

The 7950X absolutely dominates all work loads Quite amazing that the 7950x achieving 50% more efficiency in multi threaded workloads compared to the 12900k, and I would venture to say this will be even more compared to the 13900k.

25% increase in performance may not be a deal breaker for me having a 5950x, and I may wait another generation.

AMD providing integrated graphics is defiantly a plus.

 

[zmeul]

this ain't good
AMD did a Intel - gamers will not buy this, expensive CPU, hard to cool, expensive mobo, expensive RAM

 

[TheLostSwede]

edit: any thoughts where in the text i could clarify that, so it's more obvious?

Maybe include that in the test equipment being used?

Did gamers buy the 5950X?

Nice review @W1zzard Can you share a bit more regarding your genome analysis benchmark? We can DM if you dont want it out publicly.

Thanks!
