CPU frequency and number of cores

Processor families like Intel, AMD, SPARC, etc, have various process architectures with a range of frequencies. Processors with a good frequency and architecture give the best performance. Nowadays, processors have specific frequency units in GHz, which was not the case earlier. Earlier generations of processors had processing frequencies measured in MHz, so gaps in the performance of the CPU unit could be seen and analysed easily. CPU performance metrics are based on the following parameters. i. Response time Processing speed Channel capacity Latency Bandwidth Throughput Power consumption Environmental impact Gzip compression testing: This test shows how long it takes to do Gzip compression of files.
