3900x or 5800x??? Help!

[CriSis_]

Hi, 

after hunting round for a while I’ve come to the conclusion that the 5900x isn’t going to drop in price or come into stock any time soon (before September) so I’ve decided to go with either the 5800x or 3900x.

 

My work load will consist of 3D cad, most of the adobe work space, programming, gaming, perhaps streaming with friends once in a while and most general uses.

My max budget for a cpu is £500 and will most likely be paired with a 3070 or 3080 (if I can get my hands on one )

 

Which cpu will be better equipped for my work load? I’m not to sure which will be more beneficial

 

Thanks for the help,

stay safe,

Probably a 3900x tbh. The 5800x runs hot and isn't a very great value anyways, so it makes it an easier choice. A Normally-priced 5900x would be around 549 euros, right now maybe 600 since the stock still isn't great, so that's an option if you're willing to stretch, unless you have a pretty bad stock situation which it seems you might have.

Heyo,

 

Go for the 3900X with a B550 or X570 Chipset (newest chipset for possible CPU upgrades down the line). 
Your workload is heaviely multicore optimized and the 3900X got 12 cores at 4.2GHz vs 8 cores at 4.4GHz for the 5800X.
I know you should not directly compare speeds across generations but benchmarks show 15-20% faster results with the 3900X in multithreaded loads. here
Furthermore, the 3900X got more cache and is cheaper. 

 

I just bought a 3900X and I couldn't be happier, even though the "overclocking" was counterintuitive for me. (coming from a 8700K, it felt weird to overclock the chip by decreasing the voltage and letting the chip do the rest)

A few places have the 5900x for £549 but it’s out of stock and the ones that have it in stock are £600+ ... I guess if I go with the 3900x I can upgrade later to a 5900x if needed.

 

I can get the 3900x for around £396-£410 and the cheapest 5800x is £403 (in stock)

Good to hear think I might go for it . Will most likely be paring it with a b550 tomahawk mag so future comparability should be good . And yh, I heard ocing on Ryzen is rlly strange

3900X OR 5800X for 3d cad, full use of the adobe suite, gaming, streaming, programming and general purpose tasks? (all of these are of equal importance )

Re post + a poll to get a good sample of opinions to make a decision . The 5900x is well out of my price in the UK  and is mostly out of stock unless im willing to pay upwards of £650.

Most of the things you mentioned are optimized for up to 16 cores (other than programming and gaming). The 3900x has zen 2 cores which are still very good for gaming/programming. So I would reccomend the 3900x

[NattyKathy]

That's a really tough decision, both are superb CPUs. I vote the 5800X though for a mixed-use system. If you were only doing content creation I'd say 3900X but from the reviews I've read the difference in multicore performance in favor of the Zen2 12C is smaller than the difference in single/few core performance in favor of the Zen3 8C if that makes sense. Looking at all use cases both chips seem to have an about even number of situations where one is faster than the other so it's basically a wash for an all-purpose system but given the much higher per-core performance of the 5800X that would be my preferred option. When the 3900X is faster than the 5800X it's by less than one would expect, but it seems that when the 5800X is faster it's often by much more than the specs would suggest.

I'd go with 5800X cuz it's newer I'm not sure how much 4 extra cores would make his PC faster at apps.

I can suppose 5800X has higher IPC.

Maybe 5900X the best option since you probably won't upgrade PC any soon.

Hi, 

Finally managed to get hold of a temp GPU for my system (RTX 2060) while I wait for the RTX 3070 or RTX 3080 to come into stock and am now buying the rest of my parts over the next week.

 

I need to choose between the 3900x and 5800x (both £400 respectively) for a mix of 3d cad, programming, full use of the adobe suite, gaming and casual streaming once in a while with friends. 

 

Does anybody know which would be more suited for my needs? I cant seem to find a head to head video placing these two against each other. 

 

Thanks for the help, 

Stay safe,

5800X is around 8-14% better in benchmarks:

In the future, please add context to your post instead of just a link... this can be considered a LMGTFY.

Ah ok lol, sorry

[GeorgeMKane]

Doesn't the 5800X run super hot though? I would've thought a 3800X or 3900X would be better, no?

What about 10850k is that not in stock?
