SPEC has updated the Maya test suite since our last review, so we're using the Maya 2012 test rather than the older Maya 2009 benchmark. Performance is given as a single GFX composite score for each of the four cards. Just in case this is confusing: We're using a benchmark compiled for Maya 2012, but running it in Maya 2015.
Maya doesn't present any of our GPUs with a particularly demanding workload. The M6000 is only slightly faster than the K6000 here, but both Nvidia cards are about 30% faster than AMD's W9100.
AutoCAD 2015:
For AutoCAD 2015 we tested the latest version of the long-running CADalyst benchmark (now up to Version 5.5). The CADalyst tests aren't necessarily the best fit for high-end GPUs, since the workloads don't really stretch the huge framebuffers on any GPU -- but since part of the buying process is figuring out what programs do and don't benefit from high-end GPUs, we've included the results here:
Maxwell picks up about 8% over Kepler and beats the W9100 by almost 35%. AutoCAD's performance doesn't change much between lower and higher-end cards, unless you've got truly enormous models that can stretch the frame buffer.
