LuxMark 3.1

OpenCL is a platform for harnessing GPU power for activities other than real-time 3D rendering to screen, also known as GPGPU. Unlike NVIDIA’s CUDA platform, OpenCL is open source and can be ported to anything with processing power. So drivers are available for CPUs as well, both from Intel and AMD. NVIDIA's graphics cards also support OpenCL, and the latest Ampere cards can handle 3.0, whereas the AMD cards remain on version 2.1.

A popular tool for testing OpenCL performance is LuxMark. We rendered the most gruelling Hotel Lobby scene.

This was the most compelling result for the A4500. Where it is faster with 3D acceleration for visualisation, as a GPU compute device it streaks ahead. The NVIDIA RTX A4000 and AMD Radeon Pro W6800 post almost identical results in the LuxMark test, but the A4500 is 31 per cent ahead. When you also consider that you can install two cards, add in NVLink 3.0, and create a device with a combined 40GB of frame buffer, you can see what this card is really all about.
