RTX 3080 Ti Performance

Performance Summary Charts & Graphs

Gaming Performance Summary Charts

Here are the summary charts of 25 games and 3 synthetic tests. The highest settings were always chosen and the settings are listed on the chart.  The benches were run at 1920×1080, 2560×1440 and at 3840×2160.  Five cards were compared and they are listed in order starting from left to right with the reference RX 6800 XT, the RTX 3080 FE, the RTX 3080 Ti FE, the RTX 3090, and the Red Devil RX 6900 XT (which was benchmarked in April).

Most results, except for  synthetic scores, show average framerates, and higher is better. Minimum framerates are next to the averages in italics and in a slightly smaller font.  Games benched with OCAT show average framerates, but the minimums are expressed by frametimes (99th-percentile) in ms where lower are better.  

Although there is some variability, the RTX 3080 Ti FE is only around 2-4% slower than the RTX 3090 FE and it is faster than either the RX 6800 XT or the RX 3080.  It trades blows with the Red Devil RX 6900 XT in rasterized games, but is much faster in most ray traced games and a lot faster when DLSS is used.

Next we look at overclocked performance.

Overclocked benchmarks

These benchmarks are run with the RTX 3080 Ti overclocked +160MHz on the core and +700MHz on the memory versus at stock clocks.  The RTX 3080 Ti  stock results are presented first and the overclocked results are shown in the second column.

There is a small performance increase from overclocking the RTX 3080 Ti Founders Edition.  NVIDIA has  locked down Ampere cards overclocking in an attempt to maximize performance for all Founders Edition gamers.  We would also suggest that the RTX 3080 Ti FE is rather voltage constrained and if you want a higher overclock, pick a factory-overclocked partner version instead of a Founders Edition.

Let’s look at non-gaming applications next to see if the RTX 3080 Ti is a good upgrade from the other video cards we test starting with Blender.

Blender 2.92 Benchmark

Blender is a very popular open source 3D content creation suite. It supports every aspect of 3D development with a complete range of tools for professional 3D creation.

We benchmarked three Blender 2.92 benchmarks which measure GPU performance by timing how long it takes to render production files. We tested seven of our comparison cards with both CUDA and Optix running on the GPU instead of using the CPU.  We did not benchmark the RX 6800 XT using OpenCL.

For the following chart, lower is better as the benchmark renders a scene multiple times and gives the results in minutes and seconds.

Blender’s benchmark performance is similar between the RTX 3080 Ti compared with the RTX 3090.

Next we look at the OctaneBench.

OctaneBench

OctaneBench allows you to benchmark your GPU using OctaneRender.  The hardware and software requirements to run OctaneBench are the same as for OctaneRender Standalone.

We run OctaneBench 2020.1.5 for Windows and here are the RTX 3080 Ti’s complete results and overall score of 644.48.

Here is the summary chart comparing our three GeForce cards. Radeons cannot run Octane benchmark.

The RTX 3080 Ti is a decent card when used for rendering and closer to the RTX 3090 in performance than the RTX 3080.

Next, we move on to AIDA64 GPGPU benchmarks.

AIDA64 v6.33

AIDA64 is an important industry tool for benchmarkers.   Its GPGPU benchmarks measure performance and give scores to compare against other popular video cards.

AIDA64’s benchmark code methods are written in Assembly language, and they are well-optimized for every popular AMD, Intel, NVIDIA and VIA processor by utilizing the appropriate instruction set extensions.  We use the Engineer’s full version of AIDA64 courtesy of FinalWire.  AIDA64 is free to to try and use for 30 days.

Here are the RTX 3080 Ti AIDA64 GPGPU results.

Here is the chart summary of the AIDA64 GPGPU benchmarks with four of our competing cards side-by-side.

The RTX 3080 Ti is a fast GPGPU card and it compares favorably with the RTX 3090.  So let’s look at Sandra 2020 next.

SiSoft Sandra 2020/21

To see where the CPU, GPU, and motherboard performance results differ, there is no better tool than SiSoft’s Sandra 2020.  SiSoftware SANDRA (the System ANalyser, Diagnostic and Reporting Assistant) is a excellent information & diagnostic utility in a complete package.  It is able to provide all the information about your hardware, software, and other devices for diagnosis and for benchmarking.  Sandra is derived from a Greek name that implies “defender” or “helper”.

There are several versions of Sandra, including a free version of Sandra Lite that anyone can download and use.  Sandra 2021 R2 is the latest version, and we are using the full engineer suite courtesy of SiSoft.  Sandra 2020/21 features continuous multiple monthly incremental improvements over earlier versions of Sandra.  It will benchmark and analyze all of the important PC subsystems and even rank your PC while giving recommendations for improvement.

We ran Sandra’s intensive GPGPU benchmarks and charted the results summarizing them.  There was a bug in one Processing benchmark that affected the Red Devil RX 6800 XT with OpenCL that is being addressed by SiSoft.

In Sandra GPGPU benchmarks, the RTX 3080 Ti is similar in performance to the RTX 3090.  Interestingly, the RTX 3080 Ti Hashing bandwidth is much lower than the RTX 3080 and even the RX 6800 XT as NVIDIA has limited its cryptocurrency mining ability.  However, since the architectures are different, each card exhibits different characteristics with different strengths and weaknesses.

SPECworkstation3 Benchmarks

All the SPECworkstation3 benchmarks are based on professional applications, most of which are in the CAD/CAM or media and entertainment fields. All of these benchmarks are free except for vendors of computer-related products and/or services.

The most comprehensive workstation benchmark is SPECworkstation3.  It’s a free-standing benchmark which does not require ancillary software. It measures GPU, CPU, storage and all other major aspects of workstation performance based on actual applications and representative workloads.  We only tested the GPU-related workstation performance as checked in the image above.

Here are our raw SPECworkstation 3.0.4.summary and raw scores for the RTX 3080 Ti.

Here are the SPECworkstation3 results summarized in a chart along with four competing cards.  Higher is better.

Using SPEC benchmarks, the RTX 3080 Ti is similar in performance to the RTX 3090.  However, since the architectures are different, the cards each exhibit different characteristics with different strengths and weaknesses.

SPECviewperf 2020 GPU Benches

The SPEC Graphics Performance Characterization Group (SPECgpc) has released a 2020 version of its SPECviewperf benchmark that features updated viewsets, new models, support for both 2K and 4K display resolutions, and improved set-up and results management.

We benchmarked at 4K and here are the summary and the raw results for the RTX 3080 Ti.

Here are SPECviewperf 2020 GPU benchmarks summarized in a chart together with three other cards.

Again the RTX 3080 Ti is faster than the RTX 3080 and very close to RTX 3090 performance.

After seeing these benches, some creative users may wish to upgrade their existing systems with a new RTX 30X0 series card based on the performance increases and the associated increases in productivity that they require. The question to buy an RTX 3080 Ti should be based on the workflow and requirements of each user as well as their budget.  Time is money depending on how these apps are used.  However, the target demographic for the RTX 3080 Ti is primarily gaming for gamers, especially at 1440P and at 4K.

Let’s head to our conclusion.
