    Is OpenGl hardware acceleration overrated??

    Glenn Scully

      I have 2 computers that I am using Solidworks one is an older workstation and one is a new low-mid end consumer computer.  In summary the newer computer has a 20% faster CPU (based on passmark) but no graphics card (integrated graphics only).  Using Anna's punchholder benchmark they almost the same.  Using the solidworks benchmark the for processor workstation took 33% longer (seems reasonable).  In graphics the workstation took 240% longer!  For windows experience the workstation gets 6.9 for graphics and the newer computer get 5.9.  What is wrong with the FX-3800 in the workstation?  I am using driver 8.17.12.7090. My settings are 3D app global default with vertical sync off.  I have windows visual effects set to best performance and I selected an aero theme.  I can understand the new computer processor being faster it is expected but how is the integrated graphics that need to us software Open GL better than a certified graphics card? Is something wrong with the FX-3800 or the benchmark or is openGl hardware acceleration very overrated?

          As a followup to this post I got an assembly from work and brought it home to compare the function between the two computers.  The workstation can pan rotate zoom etc flawlessly.  The I5 has a low from rate when rotating or zooming and some of the parts get turn into simplified as boxes while rotating and are then return to normal when you stop rotating.  So I think anyone looking at the solidworks benchmarks to base a new hardware decision should take what they see with a grain of salt.  In my situation the benchmark did not at all represent the performance of the machine.
