Question 7800x3d vs CPU more hated than young Bieber

[megagreenball]

Hii

I have the 7800x3d and 7900x3d in my hands for free right now, and next week I need to return one.

Reading comments on YouTube benchmarks, etc., is telling me I should keep the 7800x3d. And gamers are realy realy badly hating 7900 x3d.

However, some people are saying that the 7900x3d could be improved by tweaking cores (

).

Most benchmarks don’t consider that while playing games, you have other programs working in the background such as Steam, Discord, etc. Maybe in a scenario like this, the 7900x3d could have an edge?

What are your thoughts?

Since they really aren't "free" ... The question is "do you believe the additional cost is justified?" ... That is really the question to be answered.

Free?

And gamers are realy realy badly hating 7900 x3d.

Why do they say this?
Specific reasons matter.


What does your gut tell you?
Disregarding the benchmarks and rando comments...if you choose the other one, you will be continually unhappy.

My friend owns a pawnshop and he offered me free CPU. I’m having a hard time deciding what to choose.

Some say that 7800X3D CPU has 8 cores, all of which benefit from the extra cache. On the other hand, the 7900X3D CPU has 12 cores, but they are divided into a 6+6 configuration, and only 6 cores can access the cache.

And none of them are doing your exact workload, with your exact parts, and your exact software stack running.

The core scheduling for the dual CCX models isn't perfect, so one CAN run into scenarios where higher priority tasks can get assigned to the slower CCX, and then the cpu is no faster, or even slower, than the single CCX 7800X3D at those same tasks.

I think the Ryzen 9 X3D parts are not very good options for those who actually NEED Ryzen 9, mostly due to that driver - even though improvements/optimizations have been made, consistency is more important in my book.
The same issue arose with Intel's P & E cores.

What I want to know is where is this pawn shop located that has boxed Ryzen CPU?

Just about the newest PC I have seen in any pawn shops around here is 6th gen or so. And priced horribly to boot. I had been crawling a few local ones looking for a cheap "dumb" TV set, but the options even on that were abysmal.

Is your pc already built, or are you in the process?
If running now, do you have a problem?
What are the rest of your parts?
Yes, the X3D chips are designed for gaming only.
Any other important work and one is better off with the underlying processor.
The 7900X3d is the stronger of the two; passmark ratings:
R7-7800X3d 16 34469/3757
R9-7900X3d 24 50563/4120

And, if you can pay for it, you will have fewer regrets buying the better option.

Im in the process, last thing missing is CPU.

Rest of my parts:

Kingston NV2 500GB M.2 2280​

Deepcool Wave V2 Black​

Seasonic Focus GX-850 850W 80+​

KINGSTON 16GB 6000MHz DDR5​

Rtx 4070 12GB​

I’m in Finland, some local PC shops’ belongings were auctioned off by the government. I think the PC shop owner was arrested for tax fraud.

What is the make/model of your motherboard?
Ryzen systems are very picky about cpu/mobo/ram compatibility.
Verify that the exact ram kit you picked shows up on the motherboard ram QVL list or, on the Kingston ram support list for your cpu/mobo combination.
Knowledge and bios fiddling can often get non supported combos to work.
But save yourself trouble by buying known compatible parts.

Im going to buy ASUS TUF GAMING B650-PLUS WIFI AM5 MB. I think its good enought ?

[geofelt]

I have not used that board.
But, newegg reviews do not look promising.
Look at the negative reviews of confirmed users to see if they might apply to you.
https://www.newegg.com/asus-tuf-gaming-b650-plus-wifi/p/N82E16813119595

Looking at these forums, I see just too many problems with ryzen systems compared to Intel.
Possibly because they might be more frequently purchased
Intel 13th or 14th gen processor I5 or higher combined with a B760 motherboard would, in my mind be ok.

As mentioned the 7900X3D can have scheduling issues. Keep the 7800X3D, it will do everything you need just fine.

If im using RTX 4070, CPU will be overpowered? I wouldn`t notice diffrence between 7900 and 7800 ?

Don't worry about that. There's this complete and total misconception of system bottlenecks and how that's bad. It's always going to be the case of one component or another limiting performance. The real issue being people running unlocked framerates. You're not supposed to do that except for some very limited situations. Anyways, that pairing will be just fine, myself I have a 4070Ti with a 5800X3D and it's just peachy.

No problems building AMD rigs since the 90's. Also Intel rigs. As hobby, not my real job. Maybe it is the person building the machine that causes most problems.

I've done both as well, kinda back and forth over the years as they each get better or worse. I've had zero issues building AMD or Intel but then I also know what I'm doing (for the most part), and I'm never an early adopter. Early AM4 and now AM5 have had some difficult teething pains, with AM5's being a very hot topic (literally). Anyways, for budding enthusiasts I typically recommend Intel, or an established AMD platform. It really depends on the person. Some people will have the tools to overcome issues on their own (or with a little prompting) and some should probably just buy a prebuilt and we all hope for the best. These forums are full of both.

Haven't built an AM5 machine yet. I usually wait until the teething problems have been worked out.
