VoluMark is based on pure CPU rendering without using the GPU. It is highly optimized with SIMD and multi-threading and an excellent tool to benchmark your CPU performance.
When hitting the BenchMark button benchmarking starts. The rendered volume is a micro -CT scanned head of a mouse of 500x500x400 voxels.
During benchmarking the volume is rotated for 10 seconds. At the end the score is displayed. Rendering is at 500x500 pixels and the image is upscaled to fit the display.
The number of CPU cores used is configurable.
CPU throttling can be analysed by running x10 or x100 times, statistics are displayed.
The benchmark has been optimized both for ARM and x86 processors (32 and 64 bit)
Measured VoluMark scores (32 bit) are:
97 for Samsung ARM A57 Exynos 5433 Quad 1.9 Ghz
80 for Samsung ARM A15 Exynos 5420 Quad 1.9 Ghz
72 for Nvidia Denver K1 Dual 2.5 Ghz
58 for Qualcomn 805 Krait Quad 2.7 Ghz
58 for Intel Bay Trail Z3745 Quad 1.86 Ghz
55 for Qualcomn 801 Krait Quad 2.5 Ghz
45 for Qualcomn 600 Krait Quad 1.9 Ghz
43 for QualComn 410 ARM A53 Quad 1.2 Ghz
29 for Nvidia Tegra 3 ARM A9 Quad 1.2 Ghz
26 for QualComn 400 ARM A7 Quad 1.2 Ghz
22 for RockChip RK3066 ARM A9 Dual 1.6 Ghz
19 for QualComn 400 Krait Dual 1.4 Ghz
Besides benchmarking it's possible to interact with the volume.
Drag to rotate. Pinch to zoom.
Clip volume, with first action bar button and then long press on a cube face and drag.
Change the volume transparency and contrast with second action bar button,.
drag up down to remove soft tissue, right left to increase contrast.
Third button to reset.
