SPECviewperf™ is a portable OpenGL performance 
benchmark program written in C. It was developed by IBM. Later updates and 
significant contributions were made by SGI, Digital and other SPECopcSM project group members. SPECviewperf provides a vast 
amount of flexibility in benchmarking OpenGL performance. Currently, the program 
runs on most implementations of UNIX, Windows NT, Windows 95/98 and 
Linux.
Yet again 
we can see that increasing MHz to 2.16GHz results in faster scores in these processor intensive tests. The AMD AthlonXP 2000+ 
tested better here however. 
The Persistence of Vision Ray Tracer (POV-Ray) is 
an all round excellent package, but there are two things that particularly make 
it stand out above the rest of the crowd. Firstly, it's free, and secondly, the 
source is distributed so you can compile it on virtually any 
platform.
Lower numbers denote faster calculation times 
(seconds), and hence, better performance.
  
  
    | POVRay Benchmark Results (lower is better) | 
  
    |  | Processor | seconds | Ranking | 
  
    | 1. | Pentium 4 2 GHz | 304 sec |  | 
  
    | 2. | Pentium 4 2.16GHz | 281 sec |  | 
With no 
special instructions for either CPU, the Pentium 4 produces good, but not 
especially amazing results in POVray. Knowing AMD's history with number 
crunching this is not very surprising to see, but still we can 
see some improvement with the P4 when the FSB is 
increased.
