Benchmark Results: Image Processing And Image Rendering
Image processing and rendering are CPU- and memory bandwidth-heavy tasks. The only exception is Adobe Photoshop CS6, which uses OpenCL for some filters, and consequently exploits graphics resources.
Windows 8 edges out Windows 7 in our CPU-bound test, but gets outperformed by Windows 7 when we shift the workload to OpenCL-based compute. Chances are good that this is a driver maturity issue that'll work its way out over time.
Windows 8 does better than Windows 7 in our 3ds Max 2012, Adobe After Effects CS6, and Blender benchmarks, but the lead is very small. This is really more a draw than a win for Windows 8.
Our Cinebench benchmarks end with a draw between the two operating systems.
