Performance summary charts
Here are the performance results of 35 games and 3 synthetic tests comparing the factory-clocked 12GB Red Devil and reference RX 6700 XTs with the RTX 3070 FE 8GB and versus the RTX 3060 Ti 8GB plus five other cards all at their factory set clocks. The highest settings are used and are listed on the charts. The benches were run at 1920×1080 and at 2560×1440. Click on each chart to open in a pop-up for best viewing.
Most gaming results show average framerates in bold text, and higher is better. Minimum framerates are next to the averages in italics and in a slightly smaller font. The games benched with OCAT show average framerates but the minimums are expressed by frametimes in ms where lower numbers are better.
The Red Devil RX 6700 XT & the reference RX 6700 XT vs. the RTX 3070 & RTX 3060 Ti FEs
The first set of charts show our four main competing cards. Column one represents the RTX 3070 reference version ($499) performance, column two is the Red Devil RX 6700 XT (no SEP), column three is the RTX 3060 Ti FE ($399), and column four represents the reference RX 6700 XT ($479) performance.
The Red Devil RX 6700 XT is perhaps around 1-2% faster than the reference version and it more-or-less trades blows with the RTX 3070 Founders Edition in some games although the GeForce card is faster overall using our Intel platform.
NVIDIA cards tend to be stronger in DX11, and it appears that Vulcan performance is also strong on the RTX 3070 although one has to go on a game-by-game basis to see which card card is faster in DX12. Since we do not use Resizable BAR or have Smart Access Memory, we expect that some games would shift in favor of the Radeons using a Ryzen 5000 platform.
Let’s see how the reference and Red Devil RX 6700 XTs fit in with our expanded main summary chart, the “Big Picture”, comparing a total of nine cards.
The Big Picture
The RX 6700 XT is in a class above the RX 5700 XT and it clearly outclasses the other two older cards, the RTX 2060 and the GTX 1060.
Next we look at seven ray traced enabled games, each using maximum ray traced settings where available.
Ray Traced Benchmarks
The RX 6700 XTs now appear to perform similarly to the RTX 3060/2060 Super when ultra ray tracing features are enabled in-game. But AMD has no hardware equivalent to NVIDIA’s dedicated AI Tensor cores, so it cannot take advantage of DLSS enabled games which puts its ray tracing performance even further behind.
Although AMD has promised a DLSS equivalent in the future, the RX 6700 XT cannot currently compete with the RTX 3070 or RTX 3060 Ti in our benchmarked ray traced games.
Next we look at overclocked performance.
These ten benchmarks were run with both Red Devil RX 6700 XT overclocked as far as they can go while remaining stable as described in the overclocking section. The Red Devil RX 6700 XT factory-clocked card results are presented first and the manually overclocked Red Devil is in the second column. The third column represents manually overclocked reference RX 6700 XT performance results followed by the stock results in the last column.
There is a reasonable performance increase from manually overclocking the Red Devil RX 6700 XT beyond its factory clocks which already give it an approximately 1% performance boost over the reference version. AMD has evidently locked all RX 6700 XT cards overclocking down in an attempt to maximize overall performance, but by virtue of its better cooling, the manually overclocked Red Devil achieves higher performance than the reference version which throttles when it gets too warm.
Let’s look at non-gaming applications next to see if the RX 6700 XT is a good upgrade from the other video cards we test starting with Blender.
Blender 2.912 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 2.90 benchmarks which measure GPU performance by timing how long it takes to render production files. We tested nine of our comparison cards using OpenCL for the Radeons and CUDA and OPTTIX on GeForce – all running on the GPU instead of using the CPU.
For the following chart, lower is better as the benchmark renders a scene multiple times and gives the results in minutes and seconds.
OpenCL does not appear as well-optimized for Radeons compared with either Optix or CUDA for GeForce.
Next, we move on to AIDA64 GPGPU benchmarks.
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. CPU results are also shown for comparison with both the RTX 3070 and GTX 2080 Ti GPGPU benchmarks.
Here is the chart summary of the AIDA64 GPGPU benchmarks with nine of our competing cards side-by-side.
The RX 6700 XT is a fast GPGPU card and it compares favorably with the Ampere cards, being weaker in some areas and stronger in others. So let’s look at Sandra 2020 next.
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 2020 R10 is the latest version, and we are using the full engineer suite courtesy of SiSoft. Sandra 2020 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.
In Sandra GPGPU benchmarks, since the architectures are different, each card exhibits different characteristics with different strengths and weaknesses. However, we see very solid improvement of the RX 6700 XT over the RX 5700 XT.
SPECworkstation3 (3.0.4) 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 Red Devil RX 6700XT. Here are the Red Devil SPECworkstation3 results summarized in a chart of our nine competing cards. Higher is better.
Using SPEC benchmarks, 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 new 2020 version of its SPECviewperf benchmark last year that features updated viewsets, new models, support for both 2K and 4K display resolutions, and improved set-up and results management.
Here are SPECviewperf 2020 GPU reference and Red Devil RX 6700 XT benchmarks summarized in a chart together with eight other cards.
Again we see different architectures with different strengths and weaknesses. The reference version and the Red Devil RX 6700 XT are quite close in performance and they are significantly faster than the RX 5700 XT.
After seeing these benches, some creative users will probably upgrade their existing systems with a new card based on the performance increases and the associated increases in productivity that they require. The question to buy a new video card 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 reference and Red Devil RX 6700 XTs is primarily gaming for gamers.
Let’s head to our conclusion.
