7900X to a 9800X3D worth it?

Gained some single core performance and obv lost multi due to not as many cores. Boot up seems a tad quicker, games performing well, all good. GPU upgrade is next on the cards, this CPU seems like a safe bet though for the next few years. I considered a 9900X3D or 9950X3D, but due to the chiplet design, the way the cache gets accessed. I doubt they will be faster for gaming and I don't mind just having the 8 core 16 threads, this PC is mainly for gaming.







 
I went from a 7950X3D to a 9800X3D when they finally appeared in stock properly, all I can say is........yawn, I played with it for a week or 2 and then went back to my 7950X3D, I wont ever do a downgrade like that again, honestly it felt horrible, especially as my frequency cores boost to 5.9ghz on my 7950X3D, vs the 5.425ghz on the 9800X3D, you really could tell the difference in things like installing windows, apps and drivers, the only thing I loved about it was it didnt have the long memory training that 7000 does, I think MCR is enabled by default, but doesnt require power down to be enabled too.

I may try the 9950X3D when its released, but for now im sticking with my 7950X3D.

I think this is something which gets overlooked in all the hype - I've had a few systems side by side including the 7800X3D, sadly not got my hands on a 9800X3D yet, and the difference in stuff like installing games can be massive with some of these CPUs when you've got the systems side by side.

in games did you see any real differance? i had a 7800x3d that i brake about 18 months ago and ended up with a 13900kf...
im genuinly thinking at buying a 9800x3d and moving back to AM5 but if im honest at 1440p in the games i pay the differance is next to nothing going from 7800x3d to the 13900kf.

im trying to talk my brain out of buying a 9800x3d, unless there is big gains.
i already have a board and ram from my old build.

Honestly, I cant say I noticed any difference, games didnt feel any smoother, no extra FPS.......im running a 7900XT on an Alienware AW3423DWF 165hz ultrawide for gaming, everything just felt pretty much the same in games, as above the only thing I noticed was reduced performance when installing something large like Windows, it just seemed to take a lot longer, but that could just be 16 threads vs 32 threads, at the end of the day until you get windows installed and power profiles / drivers setup, its using all the cores of the 7950X3D.

you know, when you know.. somthing will make little to no differance but your brain is just screaming do it.
i may just shelve the board i have as it was B-Grade and very cheap and wait for the next set of CPU's

Generally the higher end CPUs come with a higher boost, by 200mhz or so, the 7800X3D vs the 7950X3D is 5ghz boost vs 5.25ghz boost on the 3D cache, so if the 9800X3D vs the 9950X3D follows the same, im hoping for 5.6 or 5.7ghz boost on all cores on the 9950X3D, with a bit of tuning on curve shaper and optimizer and FMAX boost override, that can probably be pushed all cores to 5.8 / 5.9ghz, now thats a different story and much more interesting, its going to leave everything behind.

so as a person that had a 7800x3d your saying i can expect the 9800x3d to be same same before overclocking(that i just wont do).
i think im just going to stay as is for now..
 
Hey guys,

Keep going back and forth on a X3D chip. Would this be worth the upgrade? I dont do any productivity, just gaming.

This is running well but wonder if the extra Cache is worth it?
Tought to really answer this for me as I don't really know anything about X3D. So I am a former owner of 12900k,13900k and 14900k. I decided to switch to an AM5 platform as I had never tried an x3d chip. I only like to play games. So I decided to try the 7800x3d as a stop gap as I was waiting in the 9800x3d pre order queue. Straight away I loved it. Low temps, low power draw. But I did notice when reinstalling windows for the 7800x3d that app reinstallaion felt a little bit slower. Now I say 'felt' as I didn't time it but it was more of a feeling compared to my intels. I don't know the 7900x as I haven't been on AMD platform for a few years.

I game at 4k and at the time I had the 4090. Tbh it didn't feel massively different to my intels. I guess maybe the minimums might of been a little better. And in certain games I tried it was a little more smoother in some games but not all titles. After I sold my 14900k and z790 motherboard it pretty much covered the cost and gave a little extra back. 3 days after getting my 7800x3d my 9800x3d arrived I was pleasantly surprised as I wasn't expecting it to be that quick to be delivered.

When I first got the 9800x3d NGL I didn't really think much of it. It didn't stand out to me compared to the 7800x3d coming from the intel platform. And I was pretty much sure I was going to sell it and just stick with the 7800x3d for my gaming jollies. That was until I read some members talking about PBO undervolting of which I was aware, but what I wasn't aware of is that it will self boost itself due to lower temps. Then there was the clock over ride function which is pretty much pointless on the 7800x3d as they are pretty much hard capped to like 80W ish more or less. So I gave it a try it running at 5450mhz and then if you have eclk you can get past the 5450 limit. Then combined with tuning the memory which I had never done before after reading it here. Setting timings manually rather than using Expo or XMP profiles. that's when I felt it ran snappier compared to the 7800x3d setup.

here's where things take a turn for the worse. So I now have a 7800x3d and 9800x3d setup as I have two pc's now. And for some unexplained reason I got it in to my head that along with the 5xxx series launch that the 9950x3d was going to be released around the same time as well (It releases in March) to be blunt I don't need a 9950x3d in any shape or form as I only game. But I do if I am a serial tinkerer. So I sold the 7800x3d...

So for the past 15 year or so I have always had two pc's minimum that I build every year or build every generation release. And of course the 9950x3d doesn't get released. Luckily I have managed to get a 7950x3d for tinkering stop gap purpose off a gentleman off MM that will see me until the 9950x3d gets released. So this weekend I get to pit a 9800x3d against a 7950x3d. Not really sure what to expect.

So from all of this the main benefits from the 7800x3d to 9800x3d (not sure how close the 7900x is to a 7800x3d) it is a marginal increase at 4k with some benefits in the lows percentile framerate and can be a benefit to heavy CPU based titles. Most of the improvements come at lower res like 1080p and 1440p which frankly I never use. There is a performance increase productivity wise but I prefer my intels albeit at high temps and higher power usage again I am not a productivity user. And quite possibly if you are getting a 5090 you can run it to its full potential, again I have no idea as I don't have a 5090 which needs to be tested and verified.

As for whether you switch from the 7900x to the 9800x3d. I still can't answer that but make of the above post of what you will.
 
I swapped from a 7900x to a 9800x3d, the main reason I did it was because I won't to upgrade my daughters PC to AM5. I find games seem smoother, but not massively and windows doesn't seem any slower with 4 cores less.

Personally I don't think the cost of swapping CPU is worth it, I only did it as I want to upgrade my daughters 3800x. Obviously for her, going from a 3800x to a 7900x was worth it and gave me the opportunity to swap.

The reason I didn't give her the 9800x3d was because she only has a 2080 super graphics card :D

Anyway my son had a better gaming CPU than me, as he has a 7800x3d and so I couldn't use him as an excuse ;)

My son had a better CPU than me and yet again my wife says you don't have a son either you azz.

Son upgrade excuse credited yet again to @w00dy85 (copyrighted)

You are on a roll good sir. :P

yeah guys, thanks for all the input. Im going to stick with my 7900X, as i dont think that its worth it for me, as it seems the X3D chips help with the lows more than FPS, which is fine as even when my 1% lows do drop there is no stuttering, the games keep running smooth. And thats good enough for me!

Considering you have worked your way through both the AL and RL CPU's top end also, many of the AMD 3D chip offering, if you had to note practical differences that are meaningful in the games or applications you play or use, what would those be..?
Also the cost is not going to be cheap going from one platform to another, when you are playing the games you enjoy do you really appreciate having the 9800x3d over that of the 14900k in the differences it has made, perhaps more relevant as you run at 4k...?

Thanks

With the exception of the 12900k. I prefer the 7800x3d and 9800x3d over the 13900k and 14900k. When I went from the 12900k to the 13900 I could tell there was a performance uplify straight away but also the downside of that uplift was even more higher temps and more heat that needed to be exhausted out of the case. I hate summer normally. now imagine it with a 13900k and a 3090ti. it drove me bonkers the heat. The 14900k I hated. Just when I didn;t think a CPU could out put as much heat and have higher insane temps then the 14900k plodded along. this left a very very bad taste I my mouth and for marginal if any uplift. this really annoyed the hell out of me. I knew my love affair with intel was over then. Having said that I loved my 12900k.

I like intels as my way of thinking is that they are more of an all rounder. Might not truly exceed in one particular aspect but it can do the rest decently well. I am not too fond of the AMD approach if you want to game you get the 5800x3D, 7800x3d but their productivity suffers as a result for having a good gaming chip and if you prefer a more productivity bias like the non X3d then gaming has to suffer albeit it gotten better since then.

I have often said AMD users don;t know how lucky they are cost wise. I appreciate when they say AMD is expensive and that is within context of the AMD architecture. 450 for 7800x3d or 450 9800x3d on release? Try £700 each intel release. It's not like a x800X3d gaming CPU which is roughly 2 years apart on release. But I know what I signed up for when I went 12900k onwards.

As to whether I appreciate the 9800x3d over say something like 14900k for 4k gaming. To be transparent I couldn't;t tell you there is only one game I like to play and that's league of legends. You don't need a 9800x3d or a 14900k for that matter to play that game. But I do like to bench and I love to tinker. If I played other games where it make use of the 9800x3d or 14900k brute strength I could report back on it. But seeming as I only play LoL it makes no diff what CPU I use in the game and for that matter what GPU.
 
The reason I didn't give her the 9800x3d was because she only has a 2080 super graphics card :D

Anyway my son had a better gaming CPU than me, as he has a 7800x3d and so I couldn't use him as an excuse ;)

If you think about it the 9800X3D is ideal for your daughter. Nvidia cards need all the CPU help they can get because of the CPU processor overhead they suffer and the obsession with V RAM starvation limits the resolution the cards can run.
