AMD Ryzen 9 7900X3D Drops to $409, to Clash with Core i7-14700K
AMD Ryzen 9 7900X3D is the often-ignored middle child of the 7000X3D series that's flanked by the reigning gaming CPU champion, the Ryzen 7 7800X3D; and the company's flagship Ryzen 9 7950X3D, which performs within 5% of the 7800X3D in gaming, but with the added 8 cores shoring up its productivity performance against the Core i9-14900K. Pricing of the 7900X3D dropped to $409 on Amazon, which is a huge departure from its $600 launch price. At this price, the 7900X3D is set up for a direct clash with the Intel Core i7-14700K, which is going for $400, with its iGPU-disabled sibling, the i7-14700KF listed at $392.
The Ryzen 9 7900X3D is is a 12-core/24-thread dual-CCD processor, with its 12 cores spread among two CCDs in a 6+6 configuration. The first of the two CCDs has the 96 MB L3 cache thanks to the 3D Vertical Cache (3D V-cache) technology, while the second is a regular CCD with just the 32 MB on-die L3 cache, but which can sustain higher clock speeds than the 3D V-cache CCD. The similar 16 core 7950X3D flagship can be had for $600, or about $50 higher than the i9-14900K, while the 7800X3D is going for $370.

To prove anegdotal observation about new productions units, there would need to be a robust and triagulated testing on dozens of CPUs from both periods. Something that Gamers Nexus might want to do, as they did in past.
Notebooks also get priority for energy efficient bins, and AMD laptop chips these days come in both monolithic and chiplet based.
Have you asked the member whether he/she got a deal for entire system or joint parts? I am sure there were and there are better choices for some buyers, and not for others.
There is no "objective" perspective here, because buyers' choices will depend on many factors, such as use case, price, product availability, deals, enthusiasm, etc. If we agree on this, we understand each other and there is nothing more to discuss as disagreement. That's why I said above that allusion to 7600X is practically fruitless. Waste of time. La La Land.
5900X
7900X3D
Now people that have PC experience understand that there are more than double transistors
7600X
Now can we all agree that the basic notion of PC software that more transistors lead to more performance. Clock speed and transistor count are the same thing and if you tell me that a CPU that has half or more than half the transistors that you have no understanding of how PCs work. The mitigating factor in this is software and if you believe that the 7900X3D will not get better you have not tried AMD. Just for inquiry let's look at the 7800X3D
Oh that looks like less and that translates to less performance when optimized. I already showed that all cores are used and therefore the transistor count
Let's look at the 13900KS
26 billion transistors
It has more but those are comprised of E cores and we know they are weaker. That is probably why Intel are disabling HT to save on the power envelope but right now it gives you great Gaming performance. The reason it uses more power is directly related to transistor count.
I am not a simp that is just getting into PCs. I have been using Ryzen since the 1700X and before that I started my PC journey with a 965BE. As a result every CPU I have bought has been faster than the one before. Now I have a 7900X3D and love it.
What I don't understand is why people are so passionate to hate on this CPU and that leads to my responses. Imagine if you owned a Caddy STS (I had one) and people keep telling you the Chevy Cavalier is just as good.
I know what I see when Gaming at 4K. Before you jump on me realize that I have 5 PCs in my home and have tried all of them. As an example the 7600XT is a great GPU but not really better than a 6650XT at Mining. Where it shines is playing my Daughter's Games at 4K. It had a 7600X before. These are not AAA games but Games like Unpacking and Dora the Explorer.
Why do I have 5 PCs. Well 3 of them are Mining rigs and BItcoin is at $69000 Canadian. I can't even tell you what I have made but my wallet is over $7000 and growing.
I am also a person that grew up in a real Christian home. As a result I judge Good and Evil. Intel did shady practices against AMD so they do not get my money (Vote with your wallet) and Nvidia made me feel like I did not own my hardware that I paid for. As a result it has been all AMD for like 15 years.
When you do it from that tangent you are quite happy with the free upgrades that come. Some are Nvidia influenced like Freesync and FSR and some are AMD focused like Mantle and the consoles. If you have been doing it that long you probably bought a Nvidia card for Physx (Everybody played Batman) and when they removed it with a driver update it sent me further down the rabbit hole. For the reviewers out there I went from a GTS 450 to a 6800 to a 7950XT Crossfire to Vega 64 Crossfire to RDNA2 5600XT and now have a 7900XT. So yeah my 7900X3D makes my 5.0 PC sing with 2 5.0 drives and all NAND storage, just like how the 5900X does on AM4. For $400, you would be not well served to listen to the narrative, just look at reviews on Newegg or Amazon. Even if it has some propaganda inserted there are still plenty of regular people that have nothing but positive for the 7900X3D.
This is just like the 6500XT (At the time) reviewers bemoaned the lack of what made them succesful but the reviews of people who bought them were the reverse, including me appreciating that it supported 4K 120hz as I have a TV that supports that as much as we like to say the RX 570 is still relevant the lack of 4K 120Hz support means no full VRR. I even bought another one for my one of my mining rigs and since it is doing nothing that 2w power draw is also sweet.
But I stopped taking you seriously the moment you brought up religion and how AMD should be defended because of that. Didn't even finish writing a retort, that's just... baffling.
At ~$400, the benchmarks we currently have suggest to me that this CPU has become a great deal for those who need even more efficient CPU than vanilla models, a bit more than 7800X3D for productivity and a bit less than 7950X3D to save another $200, while still being really good in gaming. A perfect compromize.
Looking into performance of 7900X and 7900X3D, and other two vanilla and their X3D SKUs, I can see that X3D models are just a little bit slower due to lower TDP. I cannot see at the moment any benchmarks where V-cache itself hampers CPUs. Those applications that do not benefit from it will simply ignore it, no?
I can see that the main reason why vanilla and their X3D equivalents are so close in performance is because Zen4 CPUs scale really well to 95-96% of performance at 120-125W and little more is available beyond that point.
For games that play nicely with thread assignment and use less the 8 main threads the 7900X3D also has a 100-200mhz advantage and over the 7800X3D so there are even times were it will be faster by default.
Everyone is aware, or should be, if you don’t wanna muck about with software to properly assign tasks, the 7800X3D is the easier CPU to just pop in and deal with, but for all intensive purposes the 7950X3D is faster (disabling a CCD takes 10 seconds in the bios, same stupid argument people make about disabling ecores on intel). To the same degree in some circumstances the 7900X3D will be faster via the same process.
The out of box stock efficiency is overblown a lot, but a fair enough critique just the same. Intel pushed things a bit heavily to slightly bolster relative benchmark results. Just the same Raptor Lake/Refresh are great chips in the right hands. Alder Lake is a bit more debatable I'd argue since the cache structure was bit different and E-cores not as tunable, but at least are price aggressively at times. They still are pretty great value on a fire sale.
Overall AMD's biggest issue is pricing and value for dollar. That could change with it's next architecture, but until then unless they do more aggressive price cuts on current offerings probably won't change a great deal. One thing not so much in Intel's favor is the initial introductory pricing on Raptor Lake Refresh has eroded quite a bit, but if they can get back to that point it'll certainly puts a lot of pressure on AMD in terms of pricing and value for dollar. Really $310 for a 14700K was if anything entirely too damn cheap for the relative performance it offers that comes modestly close to a 7950X on MT and beats it easily in ST. It also basically slightly beats or matches the 13900K a in ST which is pretty respectable.
That's less than the 7800X3D with these price cuts and destroys it in MT and it's also better ST, but sure it's cache performance isn't quite as good however 7800X3D is actually the worst of the X3D chips on stacked cache amount technically speaking and frequency clocked lower in terms of binning.
It's actually really great that CPU competition is as heated as it is between AMD and Intel. It's a fantastic time for x86 hardware really and certainly can't wait to see the progress to come in the next decade. Exciting times ahead for technology.
Your 7900X3D is a BMW M5 Estate. A very fast car that can also carry a chest of draws. Problem is that a saloon M5 (7800X3D) is a better sports car and a 530d Estate (7950X) is better at carrying the chest of draws as you dont need to stop at every other petrol station on your journey.
To MOST people the compromises either dont make sense or dont offer enough benefits to outweigh other aspects that other "similar" priced offerings give in comparison.
Yes but the mitigating factor is that you are getting a BMW M5 for the price of a Cavalier. At $409 this is academic. The saloon is good reference as I will be a smoother experience with the BMW vs a Saloon as well and more fuel efficient. As I said before I live in Canada so the 7900X3D was $699 and the 7950X3D was $999. That is $300. The 7800X3D is basically $500 but was $549 for a long time. The best deal was the 7900 for $499.. Those all came later though. I do not regret my purchase in any way. You know where you notice the difference in cores? When you use your PC everyday for hours, when you fully engage with the latest specs. This actually feels better than when I had my 990FX Sabretooth (what a board).
The drawbacks? That is the narrative. If I am enjoying the hell out of my PC where are the drawbacks? I can't make anyone believe that the 7900X3D is a super fast CPU because of this sentiment. Who cares about these other metrics if you just want a fast PC that can do anything just get it. Dual CCD is not new, as much as people would like to say that Windows have done no refinement for Ryzen, well I would have to say that based on my experience I disagree.
So again the narrative has people saying that at $409 this is not a good buy because it was never sampled by AMD. This is for people that just want a fast CPU . Gaming is my hobby and 8 cores just don't do it for me anymore but I also make the occasional video. You don't know how fast your PC is until you use someone else. So yes based on my experience I can strongly recommend this chip for $409. In Canada it is $599 and the 7950X3D is $799.
None of them are inherently bad chips and all have the cache benefits of X3D. If wanted MT and X3D I'd go with the 7950X3D however generally speaking if cost wasn't a significant consideration between it and 7900X3D. Given the price difference I'd rather get a 7900X3D and higher quality memory kit and board myself which will offset the CCX problem a bit. Possibly some better storage as well. If you cut down the cache miss latency the CCX issue is less dramatic in the end.
I don't know why AMD didn't just make a 7600X3D with the same cache as 7900X3D. Those would sell really well and not be particularly expensive. Instead they made the 5600X3D more inexplicably and much much too little too late.
- gamers with gaming rigs should absolutely buy 7800X3D. No doubt about it. The best overall gaming CPU to date, hence its great popularity.
- I am in a smaller group of users who would benefit more from 12 cores; it is the best 'compromise-CPU' for productivity and gaming together without breaking the bank on higher SKUs, plus it is more efficient than vanilla model and faster in games.
- productivity powerhouses 7950X or 7950X3D are for users who need ultimate CPU, one more, another one less energy efficient SKU to anyone's liking, plus X3D is an option for some halo gaming aside from productivity
I can see that 90-100 of 7900X3D are sold every week on Mindfactory in Germany only, so some people find it interesting. This means that thousands are sold globally every week. It is impossible to assume that all those users do not know what they are doing by buyng it. That would be an absurd idea to ponder!
I will probably upgrade to Zen5, but if I was to buy today, I'd buy 7900X3D. Why?
- 12-core CPU is a sweet spot for me
- X3D model uses less energy, so more efficiency
- 7950X is £60 more expensive, less efficient and worse in gaming
- 7950X3D is £150 more expensive; not needed for intended case use
- my favourite games, such as MSFS take a great advantage of V-cache
I really need members to open their minds and think out-of-the-box.
There is space for every SKU, for every buyer and all needs.
A good 'problem' to have.
