Benchmarks - LuxMark
LuxMark is an open-source, cross-platform GPU computing benchmark. Based on LuxRender, a freeware rendering program, this GPGPU benchmark tests each graphics card's ability to construct a complex scene using OpenCL.
The extra power of the Tahiti LE architecture is better realised in an application that can push it to the limit. This GPGPU test runs around 15 per cent faster than on a Radeon HD 7870.
