AMD - Ryzen 9 7950X

[River]

Is it much faster or faster at all than a Intel i9 14900k ?

May compare the two but not sure if it is worth it.

Can get it tomorrow but big but I am worried it is a waste of time.



Is it even possible to run both systems side by side with one without a case ?

14900k is faster than the 7950x for gaming.

If you want something from AMD that can compete the 7800x3d will probably be the best option, its cheaper and uses less power and outperforms it in majority of games

Your right but I need it fast in programs too.

Stupid question but why is the 7800x3d better than the 7950X ?

Easy.

The 7800X3D has less cores but it doesn't matter when 8 cores/16 threads is enough for gaming. So forget this difference.

The other remaining difference is the 7800X3D has "faster cores" for gaming (they're actually the same underlying cores, but the X3D models having more cache speeds them up a lot on average for games so they're still faster).

For AMD's side, a rough hierarchy to think of in terms of "per core performance for gaming" (non-gaming is different)...

7000 series X3D > 5000 series X3D ~= 7000 series > 5000 series > 3000 series > etc.

Higher tiers (like Ryzen 9 versus Ryzen 7, etc.) don't offer as much of a jump in gaming performance on AMD's side like they do on Intel's side because the clock speed deficit of lower models relative to high tiers isn't as large as it is on Intel's side. They still do offer more, but the above series hierarchy roughly works.

If it's for non-gaming, the hierarchy shifts to...

7000 series > 7000 series X3D > 5000 series > 5000 series X3D > 3000 series > etc.

And in this case the higher tiers aren't moot like in gaming because more cores help with productivity a lot, so a 5000 series Ryzen 9 (especially the 16 core model) might outperform 7000 series Ryzen 5 or even Ryzen 7.

The Ryzen 9 7000 series X3Ds are a wild card. They have two CCDs but only one has the extra cache.

The 7900X3D is pretty... strange. It's a pair of hex cores (6/6 CCD configuration) and only one has the X3D cache so the 7800X3D is often better than it in gaming, and the 7900X is better than it in productivity. I honestly don't know why this chip even exists.

The 7950X3D, by contrast, is fine. It's basically a 7800X3D and a 7700X on the same chip. So theoretically you get the 7800X3D for gaming and it has the extra 8 cores for productivity still. While might fall a bit shy of the 7950X in raw productivity, it's still far better than an 8 core chip for it, so it's a really decent hybrid gaming/workstation CPU that offers almost the best of both. If you're only gaming though it's a massive waste of money. It'd be worse to spend up to this on AMD's side for gaming than it would be to spend up to a Core i9 on Intel's side for gaming, because at least doing that on Intel's side still gets you a bigger clock speed advantage relative to the lower tiers.

There's not much point in buying the 7950X over the 7950X3D if you're doing any kind of gaming, 3D cache is the only reason AMD is even a strong competitor with Intel right now in gaming performance, and with how Intel's productivity performance has improved, if Intel took advantage of cache, AMD would have a harder time beating them in general. Intel is basically letting AMD win at this point.

he is wrong.

the 7800x3d and 7950x3d perform both equal in ganing
and both better than than intel 14900k

so either amd chip is better for gaming.


the 7950x costs a few hundred more, has more cores and mote cashe.. nom of that helps you in gaming. but it does helo in multicore processes..
so for most gamers wirh 7800x3d and 7950x3d perclrming equal you will want the 7800 due it beumg much cheaper.

but as you state you need your pc also for other uses.. well than spendimg the extta money on that 7950x3d is worth it.

7950X3D is consistently faster than the 7800X3D in games and rather consistently slower than the 7950X in productivity because most of those loads don't benefit from more cache, it's mainly games that see the large gains that have been giving Intel a hard time.

Realistically if someone needs high performance for gaming and productivity, then Intel makes more sense because the 14900K is trading blows with the 7950X3D in games but clearly winning when it comes to productivity.

Gamers who want the best bang for the buck should buy the 7800X3D, those who need more should be considering a Core i9.

Is it really consistent?
According to Gamers Nexus and Hardware Unboxed the 7800x3D is slightly faster in games.
They of course can be wrong but are they?

Didn't we discuss this question somewhere in the previous topics from the same OP?

Thank you. Very helpful.

I wish a store had both side by side.

When the cache is actually being used properly, yes, which is a hit or miss depending on Windows' garbage task scheduling, R9X3D only has the 3D cache on one chiplet, not both. It's probably more consistent on Linux, these chips have garnered more performance on Arch Linux than Windows 11 and there's kernels that are optimized specifically for Zen4.

From what I've seen from other reviews, the 7950X3D was consistently slightly ahead of the 7800X3D, but marginally so, they can easily go back and forth depending on the test setup and methodology.

[Illusion of Progress]

They're basically close enough that you get equivalent performance. It's really best to treat the 7950X3D as a 7800X3D and 7700X put together on the same chip because that's what it is. It's a pair of octo core CCDs where one has 3D cache and the other doesn't, and that's what the 7800X3D and 7700X respectively are.

Before the X3D came to the Ryzen 9 tier in the 7000 series, getting a Ryzen 9 for the multi-threaded performance meant losing out on gaming performance (as the 5800X3D is just on another level compared to the 5900X/5950X in gaming) and that sort of use case (top tier gaming plus multi-threaded) was where Intel was previously just better with the Core i9 and even Core i7, so this is where the v-cache being added to the Ryzen 9 stack comes in (I still think the 7900X3D in particular is awkward as all heck though...). The 7950X3D is basically a 7800X3D that multi-threads a lot better because it has an additional 7700X on the side, but it may lose a hair of performance in gaming (really not much) due to scheduling.

Since you were originally looking at Core i9s and were interested in multi-threading (I think from other threads; you've made a lot of threads on this same subject so I've honestly lost track...), then the 7950X3D might be of interest to you over the 7800X3D. Otherwise, if this is just for gaming and you're not actually doing serious multi-threading stuff, then there's little (read as, almost no) reason to choose either the Core i9 or the Ryzen 9 X3D over the 7800X3D, as it will offer the same level of gaming performance and for much less investment.

What nonsense. You just gonna ignore reality? AMD is competitive even without 3d vcache.

With 3d vcahe AMD destroys Intel.

[The_Abortionator]

Honestly its probably gonna make more sense to go with AMD. Intels gains at the top are marginal and require you have atleast a 360 rad to get the advertised performance.

Not to mention you can air cool a 7950x if you want. Thats not an option with the 14900k.

You can also power limit the 7950x without much real world performance loss. Thats not the case with the 13/14900k as they are pretty much required to be at insane power usage to hit those numbers.

If all you are doing is gaming the 7800x3d is king. If you are going more but not really heavy production then still the same.

If you need heavier workloads then you can fish around the R9 Ryzens.

I wouldn't bother with Intel atm as they suck up so much juice and in many games are unstable unless you stable E cores.
