4.5

7 sources3 derived$1,649.96as of Oct 2

The AMD Radeon Pro W6800 is a workstation-class GPU featuring 32 GB of VRAM and hardware-based ray tracing capabilities. It's designed for demanding architectural visualization workflows and supports professional applications like Solidworks Visualize, Autodesk Maya, and Unreal Engine. While it offers significant memory capacity and viewport boost technology, it's not optimized for FP64 workloads and has limited ray tracing support compared to Nvidia's offerings. This card targets visualization professionals who need substantial memory and ray tracing performance.

Strengths

— Features 32 GB of on-board GDDR6 memory, double that of consumer counterparts
— Includes hardware-based ray tracing with dedicated Ray Accelerators
— Supports up to six displays and Error Correcting Code (ECC) memory

Watch-outs

— Not optimized for FP64 (Double Precision) code used in engineering simulation
— Limited ray tracing acceleration support compared to Nvidia RTX GPUs

Ranked #5 in Best Workstation Gpus For AI

NVIDIA RTX A5000

3.8

7 sourcesall derived

NVIDIA's RTX A5000 delivers a significant upgrade over the previous Turing-based Quadro RTX 4000 with 24 GB of GDDR6 ECC memory and Ampere architecture performance improvements. Develop3D reported that it offers substantial gains in general processing, AI operations, and hardware-based ray tracing. The card supports up to four 5K displays through its four DisplayPort 1.4a connectors and features a single-slot form factor suitable for compact workstations. However, the 24 GB memory limit may constrain very large projects, and its blower-style cooling design could be noisier than traditional axial fans.

Strengths

— 24 GB GDDR6 ECC memory provides significant upgrade from previous generation Quadro RTX 4000's 8 GB
— Ampere architecture delivers substantial performance improvements across CUDA cores, Tensor Cores, and RT Cores
— Supports up to four 5K displays via four DisplayPort 1.4a ports

Watch-outs

— Performance may be inferior to newer consumer cards
— Potential for instability and high power consumption

How they stack up

AMD Radeon Pro W6800

The AMD Radeon Pro W6800 provides 32 GB of GDDR6 memory and dedicated Ray Accelerators, making it suitable for CAD, BIM, and visualization tools. While it offers more memory than the RTX A5000's 16 GB, it's less memory-intensive than the RTX 6000 Ada Generation's 48 GB and the RTX A6000's 48 GB. Unlike the NVIDIA cards, it's not optimized for FP64 workloads and has limited ray tracing acceleration support compared to the RTX 6000 Ada Generation.

NVIDIA RTX A5000

The NVIDIA RTX A5000 offers 24 GB of GDDR6 ECC memory and is built on the Ampere architecture, providing a significant upgrade from previous generation cards. While it's less memory-intensive than the RTX 6000 Ada Generation's 48 GB and the RTX A6000's 48 GB, it provides better performance than the RTX 4500 Ada Generation in terms of CUDA cores and ray tracing capabilities. Compared to the RTX A6000, it offers less VRAM but is more affordable and doesn't require a specialized power connector.
