New CPUs and GPUs. How is the speed?

It has been a while since we posted a series of articles about best hardware for Neat Video noise reduction and for video editing in general. Since then AMD, Intel and NVIDIA have released a number of new CPUs and GPUs, so it’s time to check what speed gain is possible on new hardware.

New CPUs tested

Both Intel and AMD have updated their CPUs lines. We’ve had a chance to test some of the new CPUs directly and have also got some NeatBench results from our community (a big Thank you guys!).

AMD Ryzen 3900X wins this competition with a pretty big score. In addition to the high speed, this CPU is also compatible with PCIe 4 (the newest PCIe), which allows to use PCIe 4-compatible GPUs more effectively. However, to get this advantage you will also need a motherboard supporting PCIe 4.

GPUs battle: Speed or Value?

This time the fastest GPU was NVIDIA GeForce RTX 2080 Ti with 42.9 FPS, however AMD Radeon VII did not fall too far from it. And if you compare the prices, 2080 Ti does not look as attractive as it costs -- $1200 at the time of writing, while Radeon VII costs $850. GeForce RTX 2080 as well as Radeon RX 5700 XT both give a sound result of around 35 FPS for a more reasonable price: $720 and $440 correspondingly.

In the previous article we explained that the GPU Processing Power, Memory Bandwidth and VRAM are the parameters you want to watch for when choosing a new GPU. Head to “4 Factors when Choosing a GPU for Faster Digital Noise Reduction” article to learn more about that.

Other things to keep in mind

A very big contributor to your GPU’s speed is a PCIe bus. When using older versions of PCIe (prior to PCIe 3.0) or a eGPU via Thunderbolt connection, the data exchange between GPUs and the system memory may become a bottleneck and slow down the overall render speed.

If you are thinking about upgrading the whole system, choose a system with a fast PCIe bus, preferably PCIe 3.0 or PCIe 4.0. The latter is better because each PCI Express 4.0 lane is twice as fast as a PCI Express 3.0 one. The practical choice between these two is currently determined by the number of GPUs that you plan to use in the system. If you are going to use only one GPU, then you can already find suitable PCIe 4.0-based systems on the market, although neither NVIDIA nor AMD have supported PCIe 4.0 in their top GPUs yet. Please note that in order to work at PCIe 4.0 speed all components -- CPU, motherboard and GPU -- need to support this standard. However if you need two GPUs, then things get a bit more complicated. At the time of writing no CPUs and no motherboards are able to support more than one PCIe 4.0 GPU at full speed. In fact, if you are planning to use two fast PCIe 3.0 GPUs (such as RTX 2080 Ti), you will be better off with a PCIe 3.0 system where both CPU and motherboard provide enough PCIe lanes (32 or more). We certainly hope that the situation will improve as PCIe 4.0 support becomes more widespread.

Another thing to keep in mind is the amount and speed of RAM you have in your system. It’s a good idea to have more than 32 GB available. This raises the chances of your video editing software and plugins getting enough memory for their needs. This becomes especially important when working with higher resolution videos such as 4K and larger. Higher memory speed will also contribute to better CPU performance.

Check your system

To find out what your system is capable of at the moment, run our freely available NeatBench tool or run the Optimize Settings tool in Neat Video Performance settings. We would love you to send the results to our team (contacts)! The more data our developers have the easier it gets to optimize Neat Video and the quicker you will get your video rendered!
