 The inital RSA key generation is done the CPU. An ivybridge i7 can generate 51 keys per second using a single core. Each key can provide 1 gigahash worth of exponents to mine and a decent CPU can keep up with several GPUs as it is currently implemented.
 
-SHA1 hashing is done on the GPU. The hashrates for several GPUs we have tested are below:
