It beats the 7970 1ghz ed. in 3 out of 15 OpenCL tasks/benchmarks.
Software:
2D autocad (directx) = 580 beats the Titan.
3D autocad (directx) = Titan rules.
Autodesk Inventor (directX) = 7970 1ghz beats the titan.
Maya 2013 (OpenGL) = titan rules
CATIA (OpenGL) = 7970 1ghz beats the titan.
EnSight (OpenGL) = 7970 1ghz beats the titan.
Lightwave (OpenGL) = 7970 1ghz beats the titan.
Pro Engineer (OpenGL) = 7970 1ghz beats the titan.
Solid Works (OpenGL) = 7970 1ghz beats the titan.
TcVis (OpenGL) = 7970 1ghz beats the titan.
NX (OpenGL) = 7970 1ghz beats the titan.
Benchmarks:
Unigine Heaven & Unigine Sanctuary & Unigine Tropics (OpenGL) = Titan rules.
PostFX (OpenGL) = 7970 1ghz beats the titan.
TessMark = titan rules.
Didnt mention any OpenCL ones, nearly all of those 12/15 go to the 7970 1ghz.
So reasons to get a Titan:
3ds Max iray Render (Cuda)
Blender (Cuda)
Octane (Cuda)
Autocad (DirectX)
Maya (OpenGL)
The 7970 does OpenGL + OpenCL really well. Surprisingly well compaired to the Titan.
