After Effects CC 2018: Core i7 9700K & i9 9900K PerformanceWritten on October 19, 2018 by Matt Bach
In old versions of After Effects, it was extremely good at utilizing a high number of cores - but things changed when Adobe started adding support for GPU acceleration. Being able to utilize the GPU typically results in much higher overall performance for most AE users, but unfortunately (or fortunate if you consider your wallet) it meant that AE was no longer able to make effective use of a high number of CPU cores. Core count can still make a difference if you utilize the Cinema 4D 3D Renderer, but for most tasks the performance of each individual core is more important.
With the new 9th Gen Intel Core Processors, there are a number of improvements including a small frequency bump and an increase in core count. Where the current top-end consumer Core i7 CPU (the Core i7 8700K) has only 6 cores and a max Turbo of 4.7 GHz, the Core i7 9700K and i9 9900K both have 8 cores and a 4.9-5.0 GHz max Turbo frequency. Because of this blend of both a higher core count and a higher operating frequency, these CPUs should fare very well in After Effects but the only way to know for sure is to put them through our After Effects benchmark suite.

While benchmarking the i7 9700K and i9 9900K against the i7 8700K is likely the most direct comparison we could make, we also wanted to see how these new CPUs stack up against a number of other processors. AMD vs Intel is always a popular discussion, so we included the Ryzen 7 2700X - which tends to be cheaper than either of these new CPUs - as well as the Threadripper 1920X which is similar in price to the i9 9900K. To get an idea of whether or not purchasing a more expensive Intel CPU would give you a notable increase in performance, we also include the i7 7820X and the i9 7900X.
In order to accurately benchmark the different systems, we used a range of After Effects projects that are mostly publicly available for download. The projects we used (along with their source) are:

RAM Preview - Benchmark Analysis
In After Effects, there is a big difference between standard projects and those that utilize the Cinema 4D CPU renderer. Since not everyone uses this feature, we decided to separate out our testing results between "standard" projects and those utilizing the C4D renderer.
Before we get into the results themselves, we want to explain the scoring system used in this test. In essence, a score of "20" would mean that on average that processor was able to play our projects at 20% of the project's defined FPS. A perfect score would be "100" which would mean that the system was able to play it back in real time, although with the difficult projects we use this should never actually occur.
Starting with the standard projects (shown in blue), the i7 9700k and i9 9900K are faster than any other CPU we tested, but that only works out to being 4-7% faster than the Core i7 8700K. This certainly isn't nothing, but it will be hard to notice in the real world.
If you use the C4D rendering engine, however, these new CPUs are really good. The Core i7 9700K is about 10% faster than the i7 8700K which puts it right in line with the more expensive Core i7 7820X. At the top-end, the Core i9 9900K is about 37% faster than the i7 8700K. We didn't test the full range of Intel and AMD CPUs in this article, but if you compare it to the results in our recent After Effects CC 2018: AMD Threadripper 2990WX & 2950X Performance article, the i9 9900K is actually about the same as the Core i9 7940X which was the top performer for C4D projects.
Final Render - Benchmark Analysis
Once again, since the results will vary based on whether or not you utilize the Cinema 4D CPU renderer, we have separated our testing results between "standard" projects and those utilizing the C4D renderer:
For the final render (or export), the results are fairly similar to the RAM Preview test. With standard projects the i7 9700K and i9 9900K are about 3% and 8% faster than the i7 8700K respectively. With C4D projects, the i7 9700K is about 11% faster than the i7 8700K which is in line with the more expensive i7 7820X. The i9 9900K was once again excellent, coming in at 37% faster than the i7 8700K which is only a hair behind the more powerful CPUs tested in our previous After Effects CPU roundup article.
Are the 9th Gen Intel Core Processors good for After Effects?
Yes! The i7 9700K is roughly the same price as the i7 8700K, but scores about 6% higher in our After Effects Benchmark. The i9 9900K is a bit more expensive, but in return we saw a 17% higher score over the i7 8700K. In fact, even when using the C4D renderer, the i9 9900K is able to match much higher core count CPUs.
The score in the chart above is a weighted average of our testing based on what our customers tend to be the most concerned about. RAM Preview of standard projects makes up 40% of the overall score while the Ram Preview (C4D Renderer), Final Render (Standard), and Final Render (C4D Renderer) tests each contribute 20% towards the score.
Overall, the new 9th Gen CPUs from Intel are great for After Effects. The i9 9900K in particular is terrific as it is not only the best for standard projects, but it actually matches the much more expensive Intel X-series CPUs when using the Cinema 4D rendering engine. The biggest issue with these CPUs is not their performance, but rather the 64GB RAM limitation of the Z370/Z390 platform they use. Many AE users benefit greatly from having more system RAM which is the only reason we may still recommend an Intel X-series CPU in some situations. It has been reported by Anandtech that the i9 9900K may support 128GB of RAM in the future, but we will have to see if it ends up being stable or if the 32GB RAM modules will be at all cost effective.
Core i7 9700K vs Core i7 8700K for After Effects
For standard projects, the Core i7 9700K is about 4% faster that the Core i7 8700K but that rises to 10% faster if you use the C4D rendering engine. While this is likely not worth a straight upgrade from the i7 8700K, if you are already in the market for a new AE workstation the i7 9700K is a solid choice.
Core i9 9900K vs Core i7 8700K for After Effects
The Core i9 9900K is more expensive than the i7 8700K, but in exchange we saw an 8% performance increase with standard projects and a massive 37% performance increase when using the C4D rendering engine. This makes the i9 9900K an incredibly versatile CPU for After Effects as it is not only the best for standard projects, but also stands toe to toe with much more expensive CPUs when using the C4D renderer.
