PerformanceTest 10

PassMark Advanced GPU Compute Test

We are using PerformanceTest 10.1 and its PassMark Advanced GPU Compute Tests feature set of benchmarks. This is a suite of compute tests to test specific functions using DirectCompute and OpenCL. We have graphed out each one separately to compare in graphs.

Radeon RX 6900 XT vs GeForce RTX 3090 Compute Benchmarks PerformanceTest PassMark NBodyGravity

NBodyGravity is a physics simulation of gravity and motion. It seems the RTX 3090 is faster at this compute performance by 25%.

Radeon RX 6900 XT vs GeForce RTX 3090 Compute Benchmarks PerformanceTest PassMark Fluid Simulation

This test performs a fluid simulation using the MacCormack method to simulate a fire reaction in an enclosed volume. The AMD Radeon RX 6900 XT seems to be just slightly faster at this fluid simulation by 3% over the RTX 3090.

Radeon RX 6900 XT vs GeForce RTX 3090 Compute Benchmarks PerformanceTest PassMark Quaternion Julia Fractals

This test generates a four-dimensional Julia fractal set, which is then rendered in three dimensions and animated. Epsilon is set at 0.001 which increases the load on the GPU. The RTX 3090 is much faster at this compute task which is 51% faster than the Radeon RX 6900 XT.

Radeon RX 6900 XT vs GeForce RTX 3090 Compute Benchmarks PerformanceTest PassMark Mandelbrot

This test continuously zooms onto a particular point in a two-dimensional Mandelbrot fractal set, generating various shapes and patterns. The RTX 3090 is faster here just slightly by 3%.

Radeon RX 6900 XT vs GeForce RTX 3090 Compute Benchmarks PerformanceTest PassMark OpenCL

In the OpenCL physics testing the AMD Radeon RX 6900 XT is a lot faster than the RTX 3090 by 51%.
