How Many CPU Cores Do I Need For Gaming?​


6 cores are enaugh for gaming? do you believe that 6 and 8 cores will be enaugh in the next 3 years΄; or do yoy believe that 12 cores will be the future in some years from now??

Do you expect to see games optimised for 8 core CPUs along with their usage in the consoles?

4-8, depending on the game.
yes, maybe, yes eventually.
probably, if the game is dev'd for consoles first.

Historically game engines have mirrored what is available to consoles, so probably 8c16t zen 3 would be a good baseline. Donno if you have seen benches, but 6c12t zen 3 slams 8c16t zen 2 and intel chips so architectures matter as well.

Console devs have certain CPU IPC and GPU performance at their disposal with the PS5 and XBOX Series X. The XBOX is the better of the two, but it's only running an optimized Zen 2 with no boost clock. Per other discussions, it is a 3700Xish processor but no boost and low power limit. The Zen 3 IPC on the 6-core 5600X at stock, under stock boost, and especially when overclocked will surpass whatever the consoles deliver with "8 cores" and this will be forever. The lack of boost clock will just kill consoles compared to what we can run on PC.

GPU power on the XBOX is lower than the upcoming 6800 (fewer CUs) and the PS5 is even worse. The 6800 is supposed to have 2080TIish performance and the console GPUs will be worse with lower CU count. As we know with gaming, GPU power is far more important than CPU power. Are people trying to tell me the consoles are going to outclass my 5600X and 3080? Not a chance in hell.

Don't get me started on the VRAM debate. This is even sillier than the previous two points. VRAM is third on the list behind CPU IPC and GPU power and it's not even close.

Historically game engines have mirrored what is available to consoles, so probably 8c16t zen 3 would be a good baseline. Donno if you have seen benches, but 6c12t zen 3 slams 8c16t zen 2 and intel chips so architectures matter as well.
Not even remotely true unless by mirrored you mean PC gaming is historically held back by consoles.

For now days 6 core/12 threads is what I would get minimun or 8 core cpu. For future proofing that is. I'm still using 4 core/8 thread cpu and its fine for 1080P so far but it seems that is going to change going forward.

Neither. 5950 or bust.

I picked up a 5600x since it was easily obtainable. I'll revisit again in 6 months when other CPUs are in stock at reasonable prices. I have plenty of boards I could upgrade to a 5600x later.

What CPU did you upgrade from? Has the FPS been noticeably higher?

That's purely because the game doesn't scale at all after adding more than 12 threads. Of course at that point the IPC gains over Zen 2 are what you see as the difference.

It ALL depends on your resolution and corresponding GPU. Only the highest end CPUs aren't bottlenecking the 3090.

I still run a Ivy-E 4960X and at 1080P with a Vega 64 I have zero issues playing anything slower then the 75Hz of my odd monitor.

3600x, and I haven't really played around with it to notice a difference. I'm waiting for AC: Valhalla to release. I upgraded from a 5700xt to a 3080 also, so it's going to be hard to tell exactly how much difference it made.

Saturating available cpu cores isn't a good strategy given the recording/streaming/simultaneous workloads while gaming use cases.

Gpus can't shoulder everything yet as a coprocessor for non game load.

I mean on some level, yes, it will still play games 5 years from now. Obviously, technology marches on, and it won't be the best gaming processor you can buy. Realistically, by the time that the 8C/16T CPU is obsolete, the 12C/24T CPU from the same generation will also be obsolete.

you mean that the 5600 x can work better in games against 5950 x>??

also the ps5 have 8 cores that means that most games will be optimized for 8 cores corect??

You don't seem to be reading anything in the thread and with that I wish you luck.

I'm sorry for asking stupid question (I don't this, but my kids want to), but if anyone knows please reply...

For playing games at 1440p@165 with 3080 GPU and streaming, would 5600X (6 core be enough)? or would 5900X do much better job? I believe streaming is done off GPU, however I don't know how much OBS adds.

I bought a 5600x 6 core onlaunch day. Got around to setting it up today.

Put my temp 5600xt card on it.

Played some games.

Wow incredibly powerful 6 core cpu. Games running much smoother on it than my 24 core threadripper. But that might be due to clock speed and the new cache arrangement, or my Threadripper OS is dirty and has too much shit running. I even set 3960x to one CCD which is 6/12 threads and the 5700x is much smoother and faster in games.

I plan to return the 6 core to Microcenter and buy the 8. I need the 2nd PC for other things like small servers having my son play with me, etc.....

However, keep in mind the 3960x is still brutally faster in productivity due to massive core count and cache. I havent tested plroductivity yet. Too many family things to do right now.

That's the same setup I have. I'm going to start with the 5600X and go from there. I'm sure I will upgrade to a 5900 at some point but they are hard to find right now.

The 5600x and 5800x are the closest design to intel single processor design which still has the least amount of latency , the 5600x is a less binned chip than the 5800x. but both are godly in game performance but a built tweaked non stock 9900ks or 10900k can stay ahead

so if I read it correctly, you would recommend 8 core (to be on the safe side)?
Yes and no

Games only 6 core / end of discussion
Games and productivity / maybe 8 core but 6 is brutally fast already
Productivity and then games / 8 core

Depends on how long you keep a setup around. If you get the "itch" and upgrade every year or two just go with 6 unless you have non-gaming uses in mind for more cores. Thinking back to the benchmarks I was staring at on Thursday the 3700X and i7-10700k (stock clocks) tend to beat a 5600X in a lot of heavily threaded non-gaming apps but get beat by the 5600X in games. Nice IPC bump on Zen 3 but not enough to make up for 33% more cores in apps that really use them. If you're looking to future proof and keep it until it annoys you I'd go with 8 since that's what the next batch of consoles are using. The catch is we won't see games that really need that for a bit. A lot of the launches in the next year or two will also come out for the old Consoles, plus game devs try to make things work ok for the installed base. A lot of that is quad cores.

1440p streaming is highly limited in what platforms will accept that bandwidth for transcoding.

If you stream off your gpu you will still have some cpu impact depending on how you are pushing the stream.
OBS will have more impact on your cpu than using software baked into your gpu drivers at a high level.
This is bc OBS allows for more quality tweaking than limited gpu driver stream options, so you need to know how to stay in either lane.

Low impact would be streaming at the same resolution you game in, which is why 900p/1080p is still popular.
No extra face or keyboard cams for the cpu to deal with.
Limit audio, limit output resolution bc a lot of devices will black screen the stream if it’s too high with little transcoding support at lower res.
Know what the bandwidth and transcoding limits for the account, assuming kids that aren’t partnered or featured.
Just bc a pc can push a given rate doesn’t mean your platform will accept.

Don’t overbuy their gear, if they get good at content creation they can go buy their own upgrades.

For strictly gaming the 5600x is the best value. $150 for two more cores... yea that 150 can be spent towards something else if one has reasonable cost contraints.

Price is another issue with Zen 3 for builds that aren't about gaming, especially if you have a local Microcenter around. I wouldn't buy a 5800X for content creation. I'd get a 12-core 3900X at my local Microcenter for $400 and use the $50 saved by buying a more powerful chip on something else. Or just spend it on beer. No Microcenter? Newegg has the 3900X for $460 and I bet you can do better elsewhere. Same with new 6 cores vs old 8 cores. 3800X is $300 and 3700X is $280 at Microcenter. More at Newegg, but they haven't had the best prices for a long time. Might even want to check Best Buy. Best Buy beats Newegg prices on the 3700X by $20 and $5 on the 3800X.

Yep Microcenter, so for me the 3600 at $180 is a lot more palatable than 5600x at $300, but it does give a 20% ipc bump so maybe worth the 120 extra if ipc is your need. Heck the 9700k at 200 is a sweet chip for gaming if you are wanting to go down that road, with a 5ghz OC it it still near the top.

Early indications are also showing lower temps as well, which could be useful (like me in my mini itx). 9700k @ 5ghz is not as friendly to my case or PSU. Anyways, honestly, 6/12 will probably be about it in gaming for some time. I don't think there is much to gain from 8 cores in current or soon to be games. I bought a 3700x because I do blender and some transcoding stuff as well, and a 65w 8-core was hard to pass up for $260 on sale. It's much easier for me to pass on a $450 8 core that draws more power. If they release a 5700x @ $350 and 65w I might upgrad again. Otherwise I think the 3600x for a gaming build is the current sweet spot. If you have other uses for the cores than sure, just for gaming I wouldn't bother personally, but to each their own.

I moved from a 3600x to a 5600x and the 5600x is about 12C less under a load (95W vs 65W), and is faster. I would definitely put this CPU in a SFF system over anything comparable right now.

How Many CPU Cores Do I Need For Gaming?​

I could be wrong but it seem that it is more about multi-core performance than multicore count that is the main variable, i.e. no gaming scenario for which a 3700 will ever beat a 5600.

Some game already seem to scale significantly going over 6 cores (Vulkan Serious sam 4) or a little bit going from 6 to 8 to 12 (but stop there do not scale at 16) like Death Stranding/Shadow of the tomb raider, with a 3090 rtx at just 1080p.

Would be interesting to validate that comparing, is there a game in which a 3300x is slower than a double the amount of core cpu like a 1800x.

Now the semantic shift between multi-core performance and number of core can be a small one considering how linked the 2 tend to be, but if the question is between a 5600x or a 3700x for gaming that would answer it:

A video with some though and graph where you can see some ranking and core scaling:

You can use the most extreme scenarios right now and tell you maybe all game will be like this in the near future (3 year's or so).

Do you expect to be playing at 1080p, 1440 or 4K ?
