Which computer is the fastest to process complex data?

For processing complex data, both processor speed and RAM matter: a faster processor can perform more cycles per second, and more RAM lets the computer handle larger workloads efficiently. Choice D has the highest processor speed, 2.6 GHz, and the most RAM, 8 GB. The larger hard drive in choice C provides more storage space, not faster processing.
