Radeon Pro W6800 Review: AMD RDNA 2-Infused Workstation Muscle

AMD Radeon Pro W6800: GPGU Crypto, Image Processing and Rendering Benchmarks

How We Configured Our Test Systems: We tested the professional graphics cards represented in this article on a MSI X570 Godlike motherboard, equipped with a Ryzen 9 5950X and 16GB of G.SKILL DDR4 RAM clocked at 3,200MHz. The first thing we did when configuring the test system was enter the UEFI and set all values to their "high performance" defaults, then we disabled any integrated peripherals that wouldn't be put to use, and enabled Resizable BAR. The memory's clock was dialed in to its optimal performance settings using its XMP profile and the solid state drive was then formatted and Windows 10 Professional x64 was installed and fully updated. When the Windows installation was complete, we installed all of the drivers, applications and benchmark tools necessary to complete our tests.

Cryptography And Image Processing OpenCL Performance Tests
SANDRA's GPGPU Image Processing benchmark runs through an array of filters on its reference data and offers up an aggregate score, derived from a multitude of individual results. Its GPGPU Cryptography benchmark churns through an assortment of workloads, and presents individual results for overall bandwidth, AES256 encryption and decryption, and SHA2-256 hashing bandwidth. CUDA and OpenCL code paths are available in these tests, but we used OpenCL on all cards. Previously, using the CUDA path with NVIDIA GPUs resulted in better performance, but OpenCL actually outperforms CUDA in the latest versions of this test.

The new Radeon Pro W6800 significantly outperformed all of the other GPUs we tested in this benchmark, by a wide margin. It was over 2.45X faster than the second place finisher, Radeon Pro W5700. We wish we had a Quadro RTX 5000 or Ampere-based pro-vis GPU available for testing, but unfortunately did not have either on hand.

SANDRA's various Cryptography-related benchmarks also had the new new Radeon Pro W6800 finishing well out in front of the other GPUs in every portion of the test.

LuxMark v4
OpenCL Benchmark

LuxMark is a cross-platform, 
OpenCL-accelerated 3D rendering benchmark. It's a tool based on the open source LuxRender physically-based spectral rendering engine, which accurately models the transportation of light and supports high dynamic range. LuxRender features a number of material types to allow rendering of photo-realistic and artistic scenes. LuxRender is free software, licensed under the GPL, that offers plugins for packages like Blender, Maya, Cinema 4D and 3DS Max.

The Radeon Pro W6800 significantly outperformed all of the other GPUs in both of the Luxmark scenes we tested as well. It finished nearly 73% ahead of the next-fastest Radeon Pro W5700.

GPU Rendering Performance
IndigoBench is based on Indigo 4's advanced rendering engine and offers both CPU and GPU rendering modes for its two built-in models. The standalone benchmark is available for Windows, MacOS, and Linux and outputs results in M/Samples per second.

The Radeon Pro W6800 nearly doubled the performance of the Quadro RTX 4000 in the more taxing IndigoBench Bedroom scene, and once again, outran all of the other cards by a wide margin.

Blender v2.92
GPU Rendering Benchmark
Blender is a free and open source 3D creation suite that can handle everything from modeling, rigging, animation, simulation, rendering, compositing and motion tracking, even video editing and game creation. It has a built-in benchmarking tool that will track the time it takes to complete rendering a particular model. We used a GPU-focused BMW model for these tests here...

With both of the models we tested in the latest Blender benchmark, the Radeon Pro W6800 led the pack once again, with the fastest render times by far.
