NVIDIA GeForce GTX 660 Review


3DMark11 by Futuremark is the latest iteration of their "world's most popular" graphics benchmarking suite.  It's based upon DirectX 11 and "makes extensive use of all the new features in DirectX 11 including tessellation, compute shaders and multi-threading."

We ran the four graphics tests of the "Performance" and "Extreme" presets to determine our system graphics score.  The four tests evaluate the following:

Graphics Test 1

  • Based on the Deep Sea scene
  • No tessellation
  • Heavy lighting with several shadow casting lights

Graphics Test 2

  • Based on the Deep Sea scene
  • Medium tessellation
  • Medium lighting with few shadow casting lights

Graphics Test 3

  • Based on the High Temple scene
  • Medium tessellation
  • One shadow casting light

Graphics Test 4

  • Based on the High Temple scene
  • Heavy tessellation
  • Many shadow casting lights


Benchmarks - 3DMark11 Extreme


Again, the 9800GT had to sit out, since 3DMark11 is a DirectX 11 benchmark.  We singled out the GTX 560 Ti for Physics and overall performance, and we see a roughly linear increase in graphics scores for the GTX 560 models we've tested previously.  We see that the graphics score is ~33% better than the overclocked GTX 560 Ti with tests that are very tesselation-heavy.  This shows how far ahead the GTX 660 pulls from its predecessors in tests which are very heavy with state-of-the-art tesselation and intensive lighting.  We can also see that the physics scores haven't increased as much, so the GTX 560 Ti still offers good value for the number-crunching of physics-related modelling. 


Benchmarks - 3DMark11 Performance


We see the same overall trends in the Performance presets, which shows us that these cards are scaling roughly the same in response to more demanding environements.  The GTX 660 is again about 33% better than an overclocked GTX 560 Ti.
