Pix4D 4.5.6 - NVIDIA GeForce RTX 3080 Performance

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.

Pix4D Photogrammetry Performance Review for NVIDIA GeForce RTX 3080 10GB

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.

Test Setup

Listed below is the specifications of the system we used for our Pix4D testing:

*All the latest drivers, OS updates, BIOS, and firmware applied as of August 31st, 2020

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.
