TL;DR: NVIDIA GeForce RTX 3080 Performance in Pix4D
The RTX 3080 is a solid video card choice for Pix4D, although if you already have a high-end 10- or 20-series GeForce card then there probably isn't a reason to upgrade for this application. In our past testing we've seen more of a drop-off on the performance of older and lower-end models like the 1060 and 2060 non-Super, but most of the recent cards in the $400+ price range will give similar results.

Introduction
On September 1st, NVIDIA launched the new GeForce RTX 30 Series, touting major advancements in performance and efficiency. While gaming is almost always this media focus during these kinds of launches, professional applications like Pix4D should see some improvements as well.
If you want to see the full specs for the new GeForce RTX 3070, 3080, and 3090 cards, we recommend checking out NVIDIA's page for the new RTX 30 Series cards. But at a glance, here are what we consider to be the most important specs:
| VRAM | CUDA Cores | Boost Clock | Power | MSRP | |
|---|---|---|---|---|---|
| RTX 2070 Super | 8GB | 2,560 | 1.77 GHz | 215W | $499 |
| RTX 3070 | 8GB | 5,888 | 1.70 GHz | 220W | $499 |
| RTX 2080 Super | 8GB | 3,072 | 1.65 GHz | 250W | $699 |
| RTX 3080 | 10GB | 8,704 | 1.71 GHz | 320W | $699 |
| RTX 2080 Ti | 11GB | 4,352 | 1.55 GHz | 250W | $1,199 |
| RTX 3090 | 24GB | 10,496 | 1.73 GHz | 350W | $1,499 |
| Titan RTX | 24GB | 4,608 | 1.77 GHz | 280W | $2,499 |
While specs don't always line up with real-world performance, it is a great sign that NVIDIA has roughly doubled the number of CUDA cores compared to the GeForce RTX 20 Series cards at similar price points. At the top-end of the new line, NVIDIA appears to have also combined the roles of the previous-gen RTX 2080 Ti and Titan RTX into the new RTX 3090. It has as much VRAM as the Titan did, but for $1,000 less – putting it in the same ballpark as the 2080 Ti, but with more than double the memory and CUDA cores.
Since only the GeForce RTX 3080 is fully launched at this point (the RTX 3090 is set to launch on Sept 24th, and the RTX 3070 sometime in October) we, unfortunately, will only be able to examine the RTX 3080 at this time. However, we are very interested in how the RTX 3070 and 3090 will perform, and when we are able to test those cards we will post follow-up articles with their results.

Big thank you to Gigabyte for providing the GeForce RTX™ 3080 GAMING OC 10G sample used in our testing!
To test each video card, we used our in-house Pix4D benchmark – both the standard and extended versions. Each was run twice per GPU, and the best results were included in the charts below. Here is some basic info about the image sets in these projects:
- Rock Model – 82 photos at 20 megapixels each
- School Map – 51 photos at 18 megapixels each
- School Model – 278 photos at 18 megapixels each
- Park Map – 810 photos at 18 megapixels each
We make these benchmarks publicly available under the Creative Commons BY-ND license, so if you have a copy of Pix4D you can download them from our website and compare your system's performance with the results shown here.
Benchmark Results
Here are charts showing the performance of the new GeForce RTX 3080 compared to the other video cards we tested:
Performance Analysis
There isn't much of a difference between the cards we tested for this review, with all of them performing within 5% or less of each other. That indicates to me that either Pix4D is mostly CPU bound or else the video card's utilization in this application is somewhat limited. Digging into the processing steps within Pix4D, we can see that only Step 1's time is substantially impacted by which card is installed:

Is the NVIDIA GeForce RTX 3080 Good for Pix4D?
Yes, the RTX 3080 is a solid video card for Pix4D – although if you already have a high-end 10- or 20-series GeForce card then there probably isn't a reason to upgrade for this application. In our past testing we've seen more of a drop-off on the performance of older and lower-end models like the 1060 and 2060 non-Super, but most of the recent cards in the $400+ price range will give similar results.
As always, please keep in mind that these results are strictly for photogrammetry in Pix4D. If you have performance concerns for other applications in your workflow, we highly recommend checking out our Hardware Articles (you can filter by "Video Card") for the latest information on how a wide range of programs perform with various GPUs, CPUs, and other hardware.
