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.

Did any reviewer test with tuned ddr5 6000 memory for the 7950x3d ?

I believe Tom’s did, along with PBO. That’s where the assertions of memory performance being a diminished factor with the 3D Cache parts - again - has been coming from. Like the AM4 platform when you ease the memory performance bottleneck, the memory performance matters that much less.

Looks like tomshardware turned on expo. Not sure if they did anything else. I'll find out myself when I get a 7950x3d. It really is annoying that no reviewers ever go all out. If you know there is a chance for more speed, why not do it? It takes like 5 minutes to change these bios settings. They don't have to run all the benchmarks, just throw in a few to see whats going on and maybe a more in depth article later. I found out within 10 minutes that it made a difference with my 7950x to tune the memory.

AMD should partner with some memory manufacturer and tweak the ram to the limit. They could bundle it with the processor and make it the ultimate AMD experience or something. They aern't going to go any higher than 6000mhz easily, so they should get every bit out of it they can.

 

[LightningZ71]

Scatterbencher does a decent look at the overclocking/tuning strategies and also uses expo. I haven't seen anyone try to tune subtimings yet, but, iitwould probably make a notable difference for the 7900/7950x3d because they have a non vcache ccd. The 7800x3d may be the least affected by memory tuning.

HWUB will do a video with memory scaling.

Good review and uses some games not seen elswhere:

I think she raises another good point in regards to costs. You really can save a lot if you're willing to use an midrange air cooler on the CPU compared to a 360mm CLC on a 13900k.

Wouldn’t this only matter on production workloads? You don’t need a 360mm CLC to play games on a 13900K. Zen 4 also has way lower cooling efficiency than Raptor Lake due to the comically thick IHS they use.

Production is the only place where these CPUs make sense. You don't need a 13900K to play games.

And amusingly, all the reviews are done on gaming channels…

Both the 13900K and the 7950X3D only makes sens if you also have some work that can make use of all the other cores, if you're only for gaming 13600K, 13700K, 7600(X), 7700(X) and 7800X3D are the CPU's you should be buying.

Hardware enthusiast channels, not gaming channels: Toms Hardware, Anandtech, Techpowerup, Hardware unboxed, etc.

But sure, hardware enthusiasts often like to game as well.

Computerbase did a test with jedec 5200, expo 6000, 6200 and 6000 with tuned timings. Gain over jedec is pretty small at 3-4% for the tuned 6000 ram.

... Intel Core i9-13900KS already requires 76 watts in the single-core benchmark in Cinebench. A performance core of the Intel Core i9-13900KS already requires more energy than all 16 cores of the AMD Ryzen 9 7950X3D together, related to games.

Sorry, but this is BS. Authors should clock the 13900KS and 7950X3D the same, (e.g. to 5700 Mhz), and then measure the performance and power consumption in single thread loads. They may be surprised by the outcome.

BTW 13900KS is balls to the wall limited edition model which runs the fastest as it can no matter what, and 7950X3D is a reasonable low clocked product with sane power consumtion. They are not really comparable.

Except for Excel, in that case it's fair game.

If AMD ever decides to make a mobile CPU with 3D cache...

That sounds like B-die (3-4%) from the DDR4 era. I hate to be that guy but bandwidth matters most once the mhz starts hitting the 7200mhz+ range. They already have DDR5 sticks rated at 8000mhz.

It's just a matter of time, Dragon Range can fully utilize this tech while even hiding some of it's drawbacks.

 

[uzzi38]

ComputerBase did and they also compared it against a 13900KS with DDR5-7200 tuned.

 

[Kocicak]

"Normal K" Raptor lake CPUs are very competitive or even winning in some tasks (as Office programs), and in low thread count loads they are reasonably efficient.

BTW I myself reached a score 2407 in CNB R23 with a 13900K running at 6200 MHz and it consumed LESS than 76W, if I remember correctly it was around 50.

 

[Carfax83]

While I've seen a few people go on about Spiderman:remastered and how it uses the e-cores to precompile shaders etc, doing so comes at a significant energy cost. The 7950X3d manages to perform very well for around 85 watts with the 13900ks pulling around 200 watts in comparison. That's 40% of the power usage. THAT is a significant difference.

Spider-Man remastered doesn't use the efficiency cores to compile the shaders, it uses them for decompression. The 200w figure is due to the game being run at 720p with maxed settings with an RTX 4090, which increases the CPU load, for testing purposes. But in an actual gaming workload, the CPU will never hit 200w or even come close to it. I have this game and the package power draw at normal settings is about 120-130w for me at 4K maxed settings.

It's a very CPU demanding game due to RT effects as well as the asset decompression as the game has to stream in a lot of data. On the PS5, this is handled by the hardware decompression.

 

[Carfax83]

The 7950X3D is an impressive CPU for gaming, but it's far from the "domination" that several forum members predicted. With stock for stock memory, it slightly edges the 13900K, which is ironic because several members have argued that the 7700x/7950x was on par or even faster than the 13900K which is just LOL! When both are paired with optimal memory configuration, they are more or less the same and trade blows depending on the particular game. And to be honest, no reviewer really pushed RPL's memory ceiling. XMP DDR5 7200 can be slower than tuned DDR5 6600 in games. The secondary and tertiary timings matter a lot more and the XMP auto settings don't really touch those. Also it still appears that heavy CPU games like Spider-Man Remastered favor RPL due to it's lead in single threaded performance.

Where the 7950x3D really comes out ahead is in efficiency. It's amazingly efficient, but that's one of the effects of having such large amounts of cache ie less memory access and reduced power usage. I still think that Zen 4's memory controller is weak and flawed, but the cache definitely helps to ameliorate that issue. If Zen 4 3D had launched last year, I would certainly have given it serious consideration as someone like myself that games primarily but also does a fair bit of encoding would be a prime candidate for that CPU.

13900k with 7400Mhz

https://tpucdn.com/review/intel-core-i9-13900k/images/relative-performance-games-1280-720.png

different vs stock : 1.5%

7950X3d with 6000 + good timings

https://tpucdn.com/review/amd-ryzen-9-7950x3d/images/relative-performance-games-1280-720.png

different vs stock : 2.2%
so overall , 7950X3D is still faster than 13900K ( 7400Mhz)

Computerbase did a review for both OC and got same result.

Why are you providing testimonials for Raptor in the Zen 4 3D review thread? Chillax. We all know what it can do. The 3D on the other hand, is brand new, and the topic of discussion here.

Stop. I say this as a forum member. If you continue with your usual long winded propagandistic postings about Raptor, in a thread that isn't about it. I'll report you myself.

That you can't even discuss the topic without pimping Raptor is bad, and you should feel bad. If you were intellectually honest about it, I wouldn't mind. But you aren't. When hit with evidence to the contrary, you use the opportunity to further obfuscate whatever is being discussed about AMD. And turn the thread into a slog no one wants to read anymore. I am here in this thread, for information and analysis concerning the new Zen 4 3D. Not to read about what Raptor can do, or why you think it's better. There is already a thread for that.
