I'm looking at two comparable generic GPS receivers running WinCE6 and don't know how the differences affect performance. The following specs are the big differences in the units:

Unit A: CPU: SAMSUNG S3C2416 Processor 400MHZ, GPS: Signal Channels = 28

Unit B: CPU: MSB2531 ARM Cortex A7 32bir 800MHZ, GPS: Signal Channels = 22
