GBR_RIP Performance Benchmark
Revised February 5, 2000

The purpose of these benchmarks is to determine how memory and CPU speed effects the time required to RIP a large Gerber file. We ran the benchmarks using two separate machines.

  • A 500 MHz PIII with 128 MB RAM
  • A 500 MHz PIII with 512 MB RAM
  • A 300 MHZ PII with 512 MB RAM

In each case, the bitmap was only written to memory - not to disk and was not compressed or otherwise formatted.

 


Scale              1                                 PII    = Pentium II  333MHz with 512MB RAM
DPI             5080                                 PIII   = Pentium III 500MHz with 128MB RAM
                                                     PIII/5 = Pentium III 500Mhz with 512MB RAM

Notes:

1. The first 5 gerber files are from Artwork's benchmark set. The next 10 files were provided by Creo Ltd.

2. We do not account for any delays caused by resources used by the calling program to compress each band or to perform other housekeeping chores.

3. These times are for fast pixel placement. If improved smoothness is required, then the file will be RIP'd at twice the stated DPI resulting in 4x the processing time. Each 2x2 array of pixels is then reduced to a single pixel value.
