AMD Ryzen 5800X or 5900X

[father-ted]

Hi,

I currently have a 3700X and have the urge to upgrade to either of the above (at the same time of upgrading my gfx card from my current 1080Ti to a RTX 3080).

My PC is mainly used for gaming, would I be better off future-proofing more with the 12 cores on the 5900X? Is it worth the extra £s?

Thanks

Personally for gaming i don't think the 5900X is worth it over the 5800X, having said that there are some occasions where the extra 4 cores make a difference so if you just want the best and you can afford it go for it...

5900X is a little slower in lightly threaded tasks but considerably faster in multithreaded. Both are stupidly fast desktop chips and much faster than a 3700X, especially for gaming with a RTX 3080. I seen 10-15% performance jumps recently at 4K between a 3700X and 5900X.

Personally I think the 5900X is worth the extra money.

Ok decision made then I think - thanks

I'd wait for the Zen3 update with 3D cache coming early next year, not long to wait and especially for gaming will be a nice bump over 'plain' Zen3...

Ok I will try, I didn't know that.....but my patience may get the better of me

I had a 3700X and upgraded to a 5900X and it was definetly worth it! However, if the vCache versions are coming out soon, I would have held on - 3700X is still plenty! For now, focus on getting a new GPU as the 1080ti is becoming old now

Yeah, Zen3 is still an upgrade but AMD have given a 'date' of Q1 2022 for the vCache versions, and given numbers of 10-25% IPC improvement and 15% average in games over Zen3...

Of course this is gaming at 1080p or lower, as always with CPU related numbers... If you're still rocking a 1080Ti you might be better off getting a new GPU?

I found the upgrade from a ryzen 5 3600 to ryzen 7 5800X with a 3080 at 1440p to be quite small in terms fps gains of around 0-10% so I'd definetly wait for the Vcache versions

You wouldn't benefit from a VCache version at all as it sounds like the games you play are GPU locked, Zen 2 to Zen 3 is a huge upgrade where the CPU matters, anything up to 50%.

I won't be upgrading to the Vcache versions myself from Zen 3 as its not worth it but what I'm saying to OP is don't expect to see huge FPS increase going from a 3700X to a 5800X or 5900X as in most games it won't be noticeable especially at 1440+ outside of the odd few exceptions or old games with don't really tax the GPU and already running at over 200+ fps.

I went for the 5800x for the single threaded performance.

Your games must only use 6 cores or the Nvidia RTX scheduler must be really bad. There is more than 10% between a 3600 and 3700X.

Most games do only use 6 cores or less which is why the 5600X isn't much different in gaming then any of the other higher core count Zen 3 CPUs.

No, most games scale well past that. Maybe most of the games you play only scale to 6 cores or the RTX3080 only scales to 6 cores.

I am more than happy with my 5800X 3080 combo

Most games do not scale past 6 cores hense why it's widely accepted that if your just gaming then a 6 core CPU is fine.

It’s only widely accepted by you I think. Pretty much everything scales past 8 cores now.

Then why do all the big tech channels that review the CPUs say that if your just gaming then 6 cores are fine?.

That’s not what they say, though is it. It might be what you want hear?
