There are quite some factors to consider when building a new PC that is mainly targeted at After Effects use.
This article is about building the best bang-for-the-buck Adobe After Effects Workstation and what hardware components are the best picks for your intended use:
Let’s start out with identifying some of the workloads you might want to run when working in After Effects.
There are two main categories of workloads that we should take a closer look at:
- Active work: Active After Effects work is when you sit at your desk and are actively using your workstation. This might involve animating layers, editing your footage, adding effects, scrolling the timeline and navigating the User Interface through menus and buttons.
- Passive Work: Passive After Effects work is done when the Program executes tasks itself without you having to interact with it. Such workloads include Rendering out your Projects and Effect Processing Tasks such as Footage Stabilization.
Let’s take a look at how the CPU handles the above tasks.
Best Processor (CPU) for After Effects
1. Actively Working in After Effects
The 12-Core AMD Ryzen 9 3900X clocks at 3,8 GHz base and has a 4,6 GHz single-core turbo-clock and the i9 9900K even boosts up to 5GHz but only sports 8 Cores total.
User Interface and frame updates in After Effects heavily benefit from high core clocks.
Take a look at these benchmarks from Pugetsystems, where it becomes clear very quickly how superior high-clocking CPUs are in After Effects CC.

2. Passive tasks or using the Machine mainly as a Render-Node
Now if you are using this Computer mainly to render out projects that you have already set-up on a different workstation, you would want to go “max CPU-core count” x “CPU-core clock” or in other words max CPU-Multi-Core Performance (similar as for 3D Rendering).
This means the more cores you have and the higher those cores are clocked, the better.
Unfortunately, there are no CPUs with more than 8 cores that have Turbo-Boost frequencies as high as an i9 9900K, meaning you will have to trade clock speeds for core-count.
Excellent options here are:
- AMD Ryzen 9 3950X (16 Cores), AMD Threadripper 3970X (32 cores), 3960X (24 Cores), 2950X(16 Cores)
- Intel i9 Series 9920X (12 cores), 9940X (14 cores), 9960X (16 cores), 9980XE (18 cores)
The above recommendations don’t clock quite as high as an Intel i9 9900K Processor but because of the higher number of cores they are a lot faster in tasks that make good use of multi-threading, such as rendering.
After Effects used to make full use of all of your Cores, but Adobe refactored the renderer a few Versions back, making it much less powerful.
To still be able to make use of high-core-count CPUs though, check out the BGRenderer Plugin.
How much Memory (RAM) do you need for After Effects?
You can never have enough RAM for After Effects. If you thought Chrome was RAM hungry, think again.
The amount of RAM you will need depends a lot on what type of projects you are working on, what other programs you have opened at the same time and how many Cores your CPU has and if you are using plugins like BGRenderer.
If you are using After Effects for lower-res projects that don’t go above 1280×720 and you work in 8Bit Color and your timeline isn’t too complex or long, you might get away with 16GB of RAM without noticing any slowdowns.
I wholeheartedly recommend at least 32GB of RAM for serious After Effects use though, better 64GB if your projects are in FullHD or above and in 16 or 32Bit Color and your Footage consists of multiLayer EXRs or similar heavy footage.
After Effects will take it all, and be sure you limit the RAM usage of After Effects in your preferences, otherwise your System might crawl to a halt.
Best RAM specs for After Effects
Be sure the RAM you chose is decently clocked, with 3200Mhz or 3600Mhz usually being the sweet spot of performance to price. Look out for lower latency RAM such as CL14 or CL16 if your budget allows this.
Having at least two RAM modules makes sure they run in Dual Channel mode, giving you double the potential bandwidth for accessing your Memory. On HEDT Motherboards with chipsets such as x399, TRX40 or x299, you can double that bandwidth again if you have at least 4 RAM Modules hooked up.
Be sure to buy RAM Modules in Kits. The modules within a Kit are factory tested and guaranteed to run smoothly within that configuration of modules.
If you buy multiple kits or even modules from different manufacturers, the possibility of them not working together smoothly is much higher.
Best Graphics Card (GPU) for After Effects
Most After Effects workloads are much more dependent on CPU Performance than on GPU Performance.
It is only when using certain effects or plugins, that a strong GPU will show you noticeable speed-ups – Or if you are working on 3D-Projects and are using the After Effects Raytracing engine.
The most important features in a GPU for After Effects are the number of Compute Units (on AMD Cards) or CUDA Cores (on Nvidia’s GPUs) since After Effects can make use of these in 3D viewport rendering, as well as in speeding up some effects-calculations that might be applied to your footage.
Great choices here are the Nvidia 2070 RTX and 2080 RTX since these have a great price/performance ratio. If you have some cash left over, consider the Nvidia RTX 2080 TI for that extra bit of performance.
As you can see in the above Benchmark Rankings by Pugetsystems, it almost doesn’t matter if you buy a GPU for 150$ or one that costs 10 times that.
If After Effects is the only Content Creation Tool you are using, and you know you won’t use the Raytracing Engine or specific Effects that make use of GPU accelleration, then feel free to get a lower-tier GPU such as the Nvidia GTX 1660 or AMD Radeon Vega 64.
Also, After Effects doesn’t natively make use of Multiple GPUs, but if you also use your PC for 3D-Animation in tasks such as GPU rendering in Octane or Redshift, having Multiple GPUs will greatly increase your performance.
Best Hard-Drive (HDD/SSD) for After Effects
When working on projects in After Effects, often-times you’ll be using Footage, which is high-res and high-bit-depth. Multiple Layers of 32Bit EXRs or RED Files come to mind here, and these are huge.
You’ll greatly benefit from having a fast drive to read all this footage from, to make previews and rendering as fast as possible.
The new M.2 SSD Drives such as the Samsung 970 EVO PLUS or PRO have excellent performance and outperform any SATA SSD by far. Highly recommended for Footage, Cache and Software Drives.
The above Chart shows you how superior an nvme SSD is to HDDs or traditional SATA SSDs. Of course this is sequential performance, but random read / write and higher cue-depths too are faster on most nvme Drives.
Best Monitor for After Effects
Buying Monitors is an extremely interesting area in itself.
