Radeon Pro

Radeon Pro is AMD's brand of professional oriented GPUs. It replaced AMD's FirePro brand in 2016. Compared to the Radeon brand for mainstream consumer/gamer products, the Radeon Pro brand is intended for use in workstations and the running of computer-aided design (CAD), computer-generated imagery (CGI), digital content creation (DCC), high-performance computing/GPGPU applications, and the creation and running of virtual reality programs and games.
The Radeon Pro product line directly competes with Nvidia, i.e. their Quadro (since discontinued) line of professional workstation cards.
Products.
Radeon Pro Duo 2016.
The first card to be released under the Radeon Pro name was the dual GPU "Radeon Pro Duo" in April 2016. The card features 2 liquid cooled "R9 Nano" cores & was marketed strongly for both the running and creation of virtual reality content with the slogan "For Gamers Who Create and Creators Who Game". The aesthetics and marketing of the "Pro Duo" follow that of the rest of the "Fury" products in the "300 series".
Radeon Pro SSG.
Fiji Radeon Pro SSG.
Using AMD Radeon's GCN 1.2 architecture, the "Radeon Pro SSG" was unveiled in July 2016. SSG stands for Solid State Graphics, and the card will couple AMD's "Fiji" core with solid-state storage to increase the frame buffer for rendering. This expansion of quick access storage will, therefore, relieve the issue of latency that occurs when a GPU has to retrieve information from a mass storage device via the CPU when a card's limited VRAM is maxed out in heavy workloads. Users will be able to add up to 1TB of PCIe M.2 NAND flash memory to improve render and scrubbing times. AMD demonstrated a 5.3 fold increase in performance on 8K video scrubbing. This SSD storage space can be made available to the operating system or controlled entirely by the GPU. The Fiji-based Radeon Pro SSG card was available as a beta program.
Vega Radeon Pro SSG.
In July 2017, AMD released the Vega-based Radeon Pro SSG. The card utilizes 16GB of second generation ECC high bandwidth memory (HBM2), an upgrade from the Fiji-based card's 4GB of first generation HBM memory. The Vega card also increased the built in solid-state storage to 2TB.
Radeon Pro WX series.
Radeon Pro WX series are graphics cards designed specifically for professional applications used in engineering, design, content creation, and science. The first Radeon Pro cards with the "WX" prefix to be announced were the "WX 7100", the "WX 5100" and the "WX 4100" in July 2016. These Polaris based cards are once again aimed at the traditional professional market and are set to replace the FirePro Wx100 series and FirePro Wx300 series. These cards, along with the Pro SSG, will use the new, non-toxic and energy efficient YInMn Blue, discovered by Mas Subramanian. This unique aesthetic for the Radeon Pro line will distinguish the professional products from the consumer Radeon series.
The smallest card, the half-height "WX 4100", is marketed for use in small form factor workstations. Designed for real-time content engines and CAD and CAM manufacturing, the "WX 5100" fits in between the "WX 4100" and the "WX 7100" in terms of performance, with the latter once again marketed with emphasis on the application of VR and other media creation, while claiming to be "The Most Affordable Workstation Solution".
In June 2017, AMD announced the addition of the lower power WX 2100 and WX 3100 cards to the Radeon Pro WX series. Both cards are based on the Polaris GPU and are rated at 1.25 TFLOPS. The WX 2100 has 2 GB of GDDR5 SDRAM, while the WX 3100 has 4 GB of GDDR5 memory.
In September 2017, AMD launched the WX 9100 based on the Vega architecture. The card features 16 GB of ECC HBM2 memory and is rated at 12.29 TFLOPS. As the new flagship of the WX line, it greatly exceeds the performance of the older WX 7100 which is rated at 5.73 TFLOPS. The WX 9100 has ISV (Independent Software Vendor) certified drivers for professional applications including Siemens NX, PTC Creo, Dassault Systèmes CATIA and 3DExperience Platform, Dassault Systèmes SOLIDWORKS, and Autodesk® Revit®. The WX 9100 is particularly well-suited for mission critical workloads and complex scientific modeling because the ECC memory helps correct "single or double bit error as a result of naturally occurring background radiation."
Radeon Pro 400 series.
Mobile Radeon Pro parts were first revealed with the release of the 2016 update to the Apple 15" MacBook Pro. These appear to be Polaris 11 derived parts with 10-16 4th generation GCN compute units, providing between 1 and 1.86 TFLOPS of performance.
Radeon Pro Duo 2017.
In April 2017 AMD announced a new version of the Radeon Pro Duo for release the following month. The newer version of the Pro Duo utilizes dual GPUs from the Polaris architecture, using the same GPUs as in the WX7100. While this results a smaller number of compute units and lower theoretical performance, it allows for the inclusion of 32GB GDDR5 SDRAM and a lower board power.
Radeon Vega Frontier Edition.
AMD announced in May 2017 the Radeon Vega Frontier Edition, for release in June of that year. While not branded as a Pro product, the card is marketed within the Radeon Pro series. The Radeon Vega Frontier Edition uses the new "Next-Gen Compute Unit" and 16GB of HBM2 memory for an expected 13.1 TFLOPs of single precision and 26.2 TFLOPs of half precision performance. Ultimately, two Frontier Edition products were released with either air or liquid cooling. The liquid cooling part supported a higher TDP, and was able to reach and sustain higher clock speeds, but otherwise the two products have similar hardware specifications.
Radeon Pro 500 series.
Released in conjunction with the 2017 Apple iMac refresh, the Radeon Pro 500 series serve as GPUs for the 4K and 5K Retina Display iMacs. The 500 series ranges supports 2 to 8 GB of graphics RAM with performance from 1.3 to 5.5 TFLOPS.
Radeon Pro Vega.
The Radeon Pro Vega product line of GPUs were first announced in 2017 as a part of Apple's iMac Pro. The two models, Radeon Pro Vega 56 and 64, support 8 and 16 GB of HBM2 memory, respectively. On October 30, 2018, Apple added graphics upgrade options for their 15-inch MacBook Pro lineup consisting Radeon Pro Vega 16 and 20. Derived from Vega 12 GPU that was only used on Apple laptops, both GPU features a 4GB HBM2 memory stack and performance up to 3.3 TFLOPS. 
The second-generation, 7 nm Radeon Pro Vega II was announced in 2019 as part of Apple's third-generation Mac Pro desktop computer. The Pro Vega II supports 32 GB of HBM2 memory, while the Pro Vega II Duo combines two Vega GPUs and supports 64 GB of HBM2 memory. The Mac Pro supports up to two Pro Vega II or Pro Vega II Duo graphics cards, allowing up to four Vega GPUs and 128 GB of HBM2 memory to be used in a system.
The Radeon Pro VII was announced on May 2020, as a professional variant of the Radeon VII.
Radeon Pro 5000M series.
Released in conjunction with the 2019 Apple 16 inch MacBook Pro. Two models were announced, the 5300M and the 5500M. Both feature GDDR6 memory interfaces, with 192 GB/s bandwidth. The 5500M supports up to 8 GB of GDDR6 and 4.0 TFLOPS. In June 2020, a new 5600M GPU model with 8 GB of HBM2 memory was quietly released.
Radeon Pro W5000 series.
The Radeon Pro W5700, which is based on RDNA Architecture for desktop workstations, was officially released on November 19, 2019. The smaller model Radeon Pro W5500 was released in February 2020.
Software.
Project Loom.
At an AMD event in 2016 Project Loom was announced as a collaboration between AMD and Radiant Images. The real-time GPU accelerated photo and video stitching program will complement AMD's virtual reality development platform. While traditional photo stitching is not that much of a complex task, Project Loom aims to improve render times when tasked with the heavy workload of stitching together multiple high resolution angles to form a 360 degree VR experience, either to headsets or mobile devices. Using AMD's Direct GMA protocol, the software allows Radeon Pro graphics cards to work directly with video capture hardware to stitch together a 30 fps, 360 degree 4k resolution video from 24, 1080p cameras at 60 fps.
The software is to be competitive with Nvidia's VRWorks 360 Video SDK, and is reportedly set to be made open-source through GPUOpen.
ProRender.
The successor to FireRender, Radeon ProRender works with high-end graphics programs as an OpenCL photorealistic offline 3D renderer and raytracing engine. ProRender aims to compete with programs such as NVIDIA's Iray and other expensive, proprietary solutions. However, AMD is making ProRender free, open source and available for all graphics hardware. ProRender was released by AMD in June 2016 with support for Blender, 3D Studio Max, SolidWorks, and Maya.
Driver.
API OpenGL 4.5 is supported and 4.6 is in development.
API Vulkan 1.0 is supported for all with GCN Architecture. Vulkan 1.1 (GCN 2. Gen. or 1.2 and higher) will be supported with actual drivers in 2018.
As with other GPU architectures, the floating-point performance is dependent on the precision and the GCN generation:
For those requiring higher FP64 performance, a form of FP64 "distinct from" the IEEE double-precision can be emulated with the much faster FP32 operations. The cost is around a ~1/3 performance compared to FP32, much better than what the native support could provide.
