I'm a bit disappointed by this. It's comparable to the 12900k by the looks of things and that suggests 13900k is going to blow it out of the water.

It IS good for competition, however. It keeps Intel on their toes. It just might not be good for our wallets, since Intel could theoretically price the top tier 13th generation CPUs at higher than the top tier AMD CPUs.

I'm not planning on upgrading for a year or two (have a 10700k from my 2020 build), but if I were this fall/winter I would (even with Intel CPUs still not officially released) be buying Intel still.
The 7000 series X3D are the one to look out for, if the 3dCache benefits your application.

Maybe include that in the test equipment being used?


Did gamers buy the 5950X?

I don’t really care to get in the weeds on this, but I will say…

I purchased the 5950X at the time, because like the 7950X, it was the best overall processor. It basically does everything that the 7700X does, plus more but for extra money. I don’t build PCs strictly for gaming, and therefore to me to say a gamer would never buy a processor like this is incorrect.

These are pushed way past efficiency. Really the undervolt looks amazing though. You lose almost nothing by shaving off 50W - in fact it's actually faster in some instances.

It's a shame, at stock power consumption I don't see these processors as worth it and stock is what a majority of people will be using.

Thanks the Zen4 reviews.

I'm curious what AMD will come back with in response to the CCD boost clock disparity. If I was a CPU designer with limited good early yields, I would absolutely only put one top-tier CCD on a 7950X and 7900X package because there's no way that those boost clocks are sustainable over more than 8 cores without melting the socket. At the point where the second CCD cores are needed, you're already well into lower clock bins because of the total TDP.

Intel 10 nm isn't really competing in efficiency with TSMC's N5. Take a look at this slide from Anandtech when they limited the 7950X to 65 W, i.e. 88 W total power draw:

View attachment 263070

A full power 12900k is unable to even come close to a hobbled 7950X. this is going to be a bloodbath in servers which is the actual focus of Zen 4.
This was what caught my eye the most. Intel opened the door for higher TDP, and the infrastructure will build around that. AMD would be stupid not to join in and make a design that can at least use the extra headroom. However, they also allowed you to run it at more traditional TDPs, and it still results in a very solid product. It also tells me that mobile Zen4 is going to be very good, especially since I’m sure we’ll see a nice RDNA2 IGP.

Hi @W1zzard, great reviews thanks!
Can you please share with us how the % score of each CPU is calculated in application performance summary?
(I mean which applications contribute to the application score and at what percentage each?)


Edit: out of curiosity, when you found out based on your testing that 12900K is 4% faster than 7950X in 1080p, did you check with AMD or other reviewers what is going on? (because AMD claimed at 1080p high 7950X was 11% faster than 12900K based on their testbed and the difference between them is 15%, it's not something small)
Thanks again!

The gaming performance is excellent, but it's not outperforming Alder Lake. But as I've been saying, when most current games are not bottlenecked by Alder Lake, we shouldn't expect something to perform significantly better either until more demanding games arrives. The same will hold true with Raptor Lake too, there will probably be a few games improving, but overall it's only going to be slightly faster in gaming.

I do expect the gaming performance to be improved by AMD. But they either don't know how or don't want to do it.
Some games like Borderlands 3 show very large performance gains with the large additional cache in the Ryzen 7 5800X3D.

Which is a fair comment.
I very much doubt that people that mainly only game on their PC got one though.

All applications (not the games), equal weight of course

did you check with AMD or other reviewers what is going on?
Yeah, many of them have it match or beat 12900K, but with fewer and older games. If you look at my tests, Age of Empires, Watch Dogs, Far Cry 6, RDR2 run very well on Intel. Far Cry 6 is very memory intensive, just like FC5. Not sure what the others are doing that Alder Lake runs them so well. Given that these are recent, highly popular titles, I can't just dismiss them and cherry pick the games that I'd like to use, so that AMD beats Intel. Or should I?

At the end of the day, you should look at multiple reviews. As I said in my conclusion, gaming performance is fantastic onall these CPUs and you'll never notice a difference without FPS counter

What a beast! o_O

I'm tempted to buy one just for fun, but I know I don't need one. It's just that my 750 W Seasonic PSU and be quiet! Silent Loop 2 280 mm AIO are a bit bored with my Rocket Lake Core i7. :D

Only three things hold me back:
1. The incredible heat output of the small chiplets,
2. The cost of buying into a new platform,
3. The CCD clock speed disparity. I'll be eagerly waiting for the update in the review to see what AMD says about the matter. Hopefully it will be rectified in Agesa updates or something.

Honestly, I'm half tempted to direct die it. Although, if I have to ask how to do so then I most likely can't.

Maybe I will skip this gen, I have at moment a 5900x or I could sell this and buy that 7900x or maybe that 7700x, or even that 7950x because that 7950x will be very binned x 7900x. Other than that, need to wait for that 13400 or lower ones with minimal wattage and very good single thread, lots of choices here. At moment my 240mm aio cooler is dissipating that 5900x at 4.3ghz at 1.15v using 130 watts. Or maybe wait for the 7800x3d. The 13900x or the 13700 will be power hungry, my aio cooler will not be able to cool that down. What I like about this next gen amd is ddr5, need at least 64gb, 32gb has not been enough.

Honestly if they released these chips at their efficiency curve (like the undervolt in the review) and with X3D off the bat, they would have absolutely buried raptor lake. Right now they're on par with stock ADL....

Non-X3D Zen 4 is very underwhelming. But based on zen3 X3D, Zen 4 X3D will be incredible...

What a bad trend, so now 12k, 13k and 7000 series are going to be absolute nuclear balls of fire to attempt to cool in a reasonable fashion…

Side note, 7600 and 7700 are priced way out of their performance category; I’m going to assume some of that is attributed to the node/wafer cost, but these are not gonna sell well depending where the 13600/13700 come in.

Well, the trash power draw is no surprise after AMD said these will be 170W TDP. Wonder what the people who keep shitting on Intel over this will say now, lol.

Looks like I'll be hunting for a 5950X for an upgrade as Zen4 is is just not good enough in a lot of ways, especially for the entry price, or maybe I get a 13xxx as those will at least let me keep my RAM.

What, this beast of a CPU still draws much less power than the 12900K.

Hi,
When was 16 core+ 32 threads+ ever easy to cool ?

Multicore overclocking has always been a beast to cool
Only solution is leave on default clocks and enjoy with air/ aio cooling

A lot higher than current Intel chips.
