9800X3D vs ??????

[Pocahawtness]

I am looking to buy a new PC. AMD is something new to me, so I am very unfamiliar with what they do.

The 9800X3D seems like a good choice, but I am a little concerned that it's being over-hyped. It seems that it's an E-Sports CPU, and not necessarily for me. I'm not sure about other AMD processors though. I know very little about them.

What are your thoughts on this? Is the 9800X3D a no-brainer for gamers, or are they really just for the 1080P players?

The Ryzen X3D model of CPUs can also be quite good in productivity and work apps as well; it will just depend if the app in question does better with more cores, higher clocks, more cpu cache; etc.

With something like Video Editing for example; it usually would benefit from more cores vs higher clocks (such as what is offered via Ryzen 9 series) and because it's generally dealing with larger amounts of data, the CPU cache isn't a big deal. But in many other work apps, that CPU cache can be a big deal.

I rather an all-around processor instead of these hyped Ryzen FX CPU's but that is just me. :csd2smile:

What are you even on about? Are you lost?

The 14900K + 4090/5090 is the best all rounder.

The 14900K has a massively higher gflop score compared to the 9800x3d making the 14900K the best dedicated CPU out of the 2 in raw performance.

4K GPU bound games wont care if you're using a 14900K or the 9800X3D because the performance will be handled by the dedicated GPU you're using; the performance will be the same.

lol, the 14900k. You're funny.

[_I_]

14900k have 8 fast cores with ht, and 16 slower cores

good for highly threaded tasks of lots of tasks at the same time

but games need core performance, which the 9800x3d would be better at

13th/14th Gen CPUs to me are a complete joke. The E-Cores and OS Scheduler doesn't work properly. If that were true, there wouldn't be this growing list of Games that we needs to disable E-Cores for.

No thanks.

9950X3D is the true best all-rounder because you get the best of both worlds -- the gaming performance potential of 3D V-cache with the benefit of high performance in heavier multi-core tasks that comes with the higher core count. It might have 8 less cores than the 14900K and 285K, but it makes up for it in the fact that all 16 cores are the same architecture.

Don't only half of the views gave 3d v cache still? So it still has the issue if notable dips when it uses a core on the second ccu, meaning gir gaming you sort of need to disable half the chip.

The other CCD has boosts higher than the CCD with 3D cache to compensate, and it just comes down to scheduling to choose which CCD needs to be used, the problems with that were already mostly fixed, the user themselves can go the extra mile and control it themselves through software

People who are buying these CPUs should probably know how to do simple things like that regardless, as they are not the average user

Schedulers are supposed to prevent cross CCD hits like that for certain workloads and honestly works well enough except Windows has pretty bad schedulers and certain games are programmed in such a way where they disobey core affinity settings.

I'm lucky as thats pretty much just a Windows issue but still sucks for people who haven't moved on yet.

Would of also helped if they put 3d v cache on both ccu's.

Still, 9800x3d should be the chip most gamers should be looking at.

Not really. In many scenarios the Ryzen 9 (yes all of them) actually benchmark worse in many games, especially the 7950X3D and 9950X3D because of the way the V-Cache is divided up across CCUs and as a result many games will see in-game stutters or increases to frame-time latency. This is why gamers as a whole were LOL / ROFL when they had released the 7950X3D and we saw real world results in many games. On-par with, slightly higher then 7800X3D and in many cases, actually worse performance benchmarks overall. Which is kinda sad. In many scenarios we actually see 7950X3D does worse in many games then the 7900X

Now many seemed to have claimed this could be combated by doing a clean Win11 install + latest Ryzen Chipset driver install to get the 7950X3D back performing like it should, but if you know anything, you already know this sounds ridiculous to say the least. If somehow true, then that doesn't make a whole lot of sense.

I've only to-date seen a small # of tests with 9950X3D so hopefully something has changed. And with regards to Win11, hopefully something in that regard is fixed at some point with 24H2.

For games that know not to cross CCDs on the same job sure that'd help but most games don't use more than 8 cores and you'd still take a hit for any job that leaves on CCD to the other regardless of whether both have a cache hat on or not.

Its pretty much exclusively a Windows problem.

Not only is Linux's schedulers better but you can either use task set in either a games launch options or Steam's iteslf to manually set core/CCD affinity. Gamemode in Linux already does this automatically though.

The problem with that is that they would have to choose between splitting the same capacity between chiplets or increasing the capacity, which would further increase the cost of the CPU.

If they split the capacity, the performance impact of the cache would be less than what it is now on the 3D cache CCD we got with the 9950X3D, and as is it's already a very expensive CPU that isn't going to sell out every single unit when most people can't afford it at its current pricing.

The scheduling issue is with Windows anyway which is biased towards Intel, Linux has far better scheduling and is able to perform noticeably better with Ryzen CPUs in particular compared to Windows because the kernel and scheduler aren't inherently biased, you can optimise them for any CPU.

Most games leave it up to however the OS scheduler handles things across cores/threads. Especially as so many game devs have gotten lazy over the years. How the OS handles that can sometimes be dictated via certain BIOS settings too. But it one major reason many were suggesting to use Win11 over Win10 and such for AM5 platform, especially where Ryzen 9 or any of the X3D CPUs are concerned because of the better more refined OS scheduler.

I also would not doubt many users fail to bother with installing or ensuring AMD Chipset Driver is up to date, which can also help.
