13700k VS 5800x3d on DDR4, worth the price difference?

[Zarax]

Hello,
I'm evaluating two identical configurations (aside from CPU and motherboard), one using a 5800X3D and one with a 13700k.

Everything between them is exactly the same except for CPU and motherboard but the 13700k configuration is approximately 200€ more expensive, using 64GB Kingston FURY Beast 3.200MHz (KF432C16BBK2/64) as RAM kit.
Which one would be better form a longevity standpoint? Take into account right now I have a 3770k.
I'm not going to change CPU for a long time (6+ years) and when I do it's going to be a full system rebuild so please leave out any other suggestion right now.

Thanks in advance!

Intel will be better for multi core work, but has a huge cache disadvantage.

I suppose the question is how well will a 8c 16t chip perform in 6 years and will the extra cores of Intel offer noticeably more performance then.

I’d be carful using such high density memory with either system.

Do you have any negative reports about 2x32 kits?

Intel , only way would consider 5800x3d if already on am4 to drop CPU in wouldn't do new build for it

Why the need for 64gb of ram if you doing productivity even less reason for the 5800x3d

Because 90% of the time I would be gaming and 10% running machine learning workflows that requires a ton of RAM. Also a little bit of future proofing, 16GB in 2013 was seen crazy yet now they pay themselves in extra longevity...

It can be an issue with desktop kit. I’d check the memory is on the QVL list of the motherboard maker at least. Personally I’d lean toward 4 matched sticks of 1R low density and avoid anything 2R.

I'm getting it a semi-pre built so hopefully the manufacturer will have cleared those issues.

If that 10% needs the CPU I'd get the 13700K by a mile, it just smashes the 5800X3D (it can be literally twice as fast in some tasks) and you're unlikely to notice the difference in games.

If you don't intend to overclock, then you could potentially have some ££ by going with a B760 & 13700 non-K combo (or Z690 if it has bios flashback).

Coming from the 3770k I'm confident either way I'll be pretty much blown by performance jump, what I'm trying to do is to understand if the extra multi core performance is worth the extra cash.

13700k on DDR4 seems the most balanced option so far, paired with a 6700xt it should provide decent 1080p/1440p for quite a while in gaming while being flexible for other tasks from what I'm gathering.

 

[Zarax]

13700K is overkill for a 6700 XT, a i5-13500 or 5700X would be fine, but I guess you'll be ready for a 4080/4090.

It is today but not for the equivalent card in 5 years.

The 13700K gives the 5800X3D an absolute spanking overall, so this is not even a contest. Plus if you keep it for a long time the better CPU makes even more sense. Paying 33€ more a year is nothing by comparison. Though you did not mention what you will actually use it for so we're just left throwing darts in the dark based on our biases.

On the other hand I'm not sure why you wouldn't go AM5 and then 5 years or so in you will be able to drop a 9950X3D or whatever's end-game on AM5 then and you'll have a much stronger system & won't need to re-buy RAM & Mobo, or fiddle with the build as much.

I didn't specify because I wanted a full spectrum of answers, biases included. Saying 90% gaming 10% machine learning isn't going to be more helpful anyway.
As for the other part of your post... Even though I'm a very long term PC users and I'm comfortable with upgrading components I'm not keen on replacing CPUs as I'm clumsy and the risk of bending pins is a strong disincentive to me, plus by the time the CPU will truly hold everything back (meaning <60 fps in games) it's usually time to upgrade everything.

My 10 year old 3770k doesn't feel slow (but then I'm not playing cutting edge either!) and to give you specifics this is what I'm likely to play in the next 2 years along with some gamepass stuff: https://www.gog.com/en/u/Zarax999/wishlist

In 5 years I might be adding Cyberpunk 2077 to that list (when they will stop updating it and price will drop to 10€ on sale) but the most CPU demanding title I could imagine would be an hypothetical Cities: Skylines 2.
I doubt there are benchmarks for classical machine learning workflows (like the CRAN Random Forest package) but given my current PC I'm sure I'd see an uplift either way

My personal bias is: I used exclusively Intel since 1988, I'm curious about the Zen 3D platform but I'm scared about potential issues, hence a very late series seemed enticing (by now drivers and BIOS are very well tested), especially at -10% platform cost. Current gen AMD seems too costly for my taste although I'm not thrilled by Intel mixed cores either (wasted opportunity IMHO, they could have made some truly specialized heterogeneous architecture!) so in a bit of a stump.

Phoronix (13600K review) and TPU (13700K review) have quite a variety of benchmarks in their reviews, but whether any of them are directly relevant for you, I have no idea.

Thanks but unfortunately they took all examples of neural networks (which BTW are better devoted to a GPU).
Those took all the media hype in the recent years but businesses tend to rely on different algorithms for their use cases and TBH who runs that stuff is usually not interested in benchmarks, especially as it would require a large enough public dataset to train on (the Titanic one is too small to appreciate measurable differences).
