AMD Radeon RX 6800 XT : Benchmarking Notes
In this review, we will take a look at its gaming performance (with and without Smart Access Memory), and compare it to seven other graphics cards :
- NVIDIA GeForce RTX 2080 SUPER
- NVIDIA GeForce RTX 2070 SUPER
- NVIDIA GeForce RTX 2060 SUPER
- AMD Radeon RX 5700 XT
- AMD Radeon RX 5700
- NVIDIA GeForce GTX 1080 Ti
- NVIDIA GeForce GTX 1070 Ti
Here is a quick comparison of their key specifications:
| Min. Texture Fill Rate | Min. Pixel Fill Rate | Graphics Memory | Memory Bandwidth | |
| Radeon RX 6800 XT | 580.3 GT/s | 257.9 GP/s | 16 GB GDDR6 | 512 GB/s |
| GeForce GTX 1080 Ti | 331.5 GT/s | 130.2 GP/s | 11 GB GDDR5X | 484 GB/s |
| GeForce RTX 2080 SUPER | 316.8 GT/s | 105.6 GP/s | 8 GB GDDR6 | 496 GB/s |
| Radeon RX 5700 XT | 256.8 GT/s | 102.7 GP/s | 8 GB GDDR6 | 448 GB/s |
| GeForce GTX 2070 SUPER | 256.8 GT/s | 102.7 GP/s | 8 GB GDDR6 | 448 GB/s |
| GeForce GTX 1070 Ti | 224.3 GT/s | 102.8 GP/s | 8 GB GDDR5 | 256 GB/s |

Here are the specifications of the AMD testbed we used.
| Processor | AMD Ryzen 9 5950X |
| Motherboard | ASUS ROG Crosshair VIII Hero |
| Memory Speed | G.SKILL Sniper X DDR4-3400 (8 GB x 2) Corsair Vengeance LPX DDR4-3200 (8 GB x 2) |
| Monitor | Dell P2415Q Ultra HD Monitor |
| Storage | 1TB SanDisk Ultra 3D SSD |
| Operating System | Microsoft Windows 10 (64-bit) |
| Graphics Drivers | NVIDIA GameReady Driver 457.30 AMD Radeon Software Adrenalin 20.45.01.12-11.6 Beta |
AMD Radeon RX 6800 XT : In Action!
Our testbed pairs the AMD Ryzen 9 5950X processor with the ASUS CROSSHAIR VIII Hero (AMD X570) motherboard, with 32 GB of DDR4 memory.
Take a look at the Radeon RX 6800 XT in action, and listen to how quiet it sounds… even when it revs up during the strenuous part of the test!
AMD Radeon RX 6800 XT : Peak Exhaust Temperature
We recorded the peak exhaust temperatures of those cards, to see how much heat they throw out. Take a look…
Note that these are not the recorded temperatures, but how much hotter the exhaust air is above ambient temperature.
Rated for 300 watts, AMD Radeon RX 6800 XT is definitely a hot card, blowing out really hot air like a hairdryer. The good news is – its triple axial fans are quiet even during the most strenuous tests.
But please make sure your case is well-ventilated, as the hot air is expelled from the top and bottom of the card, and will recirculate within the case.
It will get really, REALLY hot inside the chassis if you don’t ventilate well!
AMD Radeon RX 6800 XT Performance : 3DMark
We used 3DMark’s Time Spy and Time Spy Extreme synthetic benchmarks, which offers a great approximation of gaming performance in general.
The Time Spy and Time Spy Extreme benchmarks support DirectX 12, and the latest features like asynchronous compute, and multi-threading support.
Time Spy – 2560 x 1440
Look at that! The AMD Radeon RX 6800 XT was about 52% faster than the RTX 2080 SUPER, and 73% faster than the RTX 2070 SUPER!
In the overall gaming score, the AMD Radeon RX 6800 XT ends up about 42% faster than the RTX 2080 SUPER, and 58% faster than the RTX 2070 SUPER. Very impressive!
Time Spy Extreme – 3840 x 2160
At the higher 4K resolution, the AMD Radeon RX 6800 XT did even better – it was about 56% faster than the RTX 2080 SUPER, and 77% faster than the RTX 2070 SUPER!
In the overall score, the AMD Radeon RX 6800 XT was about 48% faster than the RTX 2080 SUPER, and 65% faster than the RTX 2070 SUPER!
Port Royal (Ray Tracing)
Nice! The AMD Radeon RX 6800 XT was about 29% faster than the RTX 2080 SUPER, and 49% faster than the RTX 2070 SUPER in ray tracing!
DirectX Raytracing Test
We ran the standalone DirectX Raytracing test too, and it confirmed that the AMD Radeon RX 6800 XT was about 22% faster than the RTX 2080 SUPER, and 47% faster than the RTX 2070 SUPER in ray tracing!
PCI Express Bandwidth
The AMD cards all support PCI Express 4.0, which gives them an edge over the NVIDIA cards.
