Lagging so much preview After effects and Premiere Pro on nvidia rtx 2060 super and amd ryzen 3700x

[Blinnnarts]

Hello!My after effects is lagging(preview) on not hard scenes.Adobe remote sessions cant help me and specialist said me i need to post my problem here.My pc config:

Amd ryzen 3700x, nvidia rtx 2060 super, ballistix aes 32 gb, ssd samsung 970 EVO plus 500gb, motherboard asus prime x570-P, hdd seagate barracude 2 tb.Im working on Windows 10 2004.

I cant solve this problem for 1 month.I did so many actions,but nothing helped.I really appreciate all your answers and help.Information:ae use 55% of my cpu power maximum,i dont know why.I tested my cpu and gpu and its okay.I think i need do something not in after effects,because i did all i can in settigs,e.t.c.Solving this problem is not easy,please dont write me somehing like "clear cashe".

If you need more information please write comment and i will provide all inf.Specialist said that problem in hardware,not in ae,not in project,not in windows account and thats why i dont even know what i can write else.Sorry for my english,thank you for all your help in advance!

Here is the problem:

After Effects is not well multi-threaded to begin with. In fact, it cannot take full advantage of more than eight processing threads total. Your CPU, however, has 16 threads. That means that After Effects performance relies very heavily on both CPU IPC and high clock speeds. It just so happens that AMD CPUs have a significantly lower clock speed, even with only one core in use, than contemporaneous Intel CPUs.

As such, when it comes to After Effects performance, that Ryzen 7 3700X performs right in between two budget quad-core Ryzen 3 CPUs - the Ryzen 3 3100 and the Ryzen 3 3300X. That does not inspire confidence when After Effects is the only content app you're using.

Thank you so much for your answer.Its mean i need buy intel?I know that intel in ae is faster,but really too much?Because ae lagging very,very much,1 frame can loading 3-6 sec in quarter relosution on not super super hard scenes.

[RjL190365]

Yes. There is not much that you can do, especially since you can actually go cheap on the Ryzen 3000-series non-G line and still achieve almost the same level of performance as your 3700X for After Effects.

Now, if you're running other CPU-intensive apps such as Premiere Pro, then yes, the 3700X is worth the additional power and cost.

Oh,i really didnt know about that.I have watched so many videos about config for after effects and other and nobody said about this.So,thank you.I work in premiere pro,but i use after effects more than premiere,so i really need intel cpu.If it is not hard for you,can you give me advice about intel.Which cpu should i buy,that cost like 3700x(+- 100$) and will be better.If you know about it of course.

[RjL190365]

The closest CPU (cost-wise) on the Intel side would be the recently available Intel i5-10600K, which has 6 cores and 12 threads. You'll also need a Z490 chipset-based motherboard and a new aftermarket cooler for that CPU as none of the K CPUs come with a cooler at all.

Thank you.

I hope it's okay if I bud in - thanks for this thread.  I too am struggling with a new computer.. I need to use After Effects and Premiere Pro.  Budget is $1300 so I purchased a cyberpc amd ryzen 7 3700x and GPU AMD Radeon RX 5700xt.   I have an SSD and 16 gig ram.  (will upgrade ram in next few weeks).

Why is my After Effects crashing the second I put anything on the timeline?  should I return this and get an Intel - even an intel i5 would work okay in both PP and AE?  I don't understand what you are saying about the chipset based motherboard.. and a cooler... I'm purchasing a prebuilt PC. 

Thank you very much for your advice. This thread is really helping me too!

Most Intel prebuilt PCs will come with locked, non-overclockable CPUs and non-tweakable motherboards and motherboard chipsets.

And your After Effects is crashing, not because of the CPU, but the GPU. You see, currently available drivers for all of the RDNA-based Radeons, including the RX 5700XT, have serious teething problems when used with content-creation programs.

And if I were you I would buy a new prebuilt PC somewhere else. CyberPower and iBuyPower are both subsidiaries of the same company - one whose reputation as a PC builder/assembler is less than stellar.

Unless you're cutting H.264/HEVC, then you want that sweet, sweet Quick Sync in Intel.

I have underdtand.Thanks.Its really sad,that so many popular and no popular sites are recommeding ryzen for ae.

[RjL190365]

Now, if this were between a really low-end Intel CPU that's locked and a comparably priced AMD, then yes, go for the AMD. But most mainstream Intel CPUs can sustain significantly higher clock speeds than comparable Ryzen CPUs when no more than half of the CPU's cores are being utilized, thereby more than negating the IPC advantage for the Ryzen.

In other words, the significantly higher lightly-threaded clock speeds of Intel CPUs more than compensate for the comparatively small deficit of Intel's IPC.

And the performance problems of After Effects boil down to the fact that AE itself simply cannot utilize more than a quad-core CPU to anywhere near its fullest capability to begin with. This means that the performance improvement of After Effects will begin to flatline above 4 threads.
